Open PDF after download with DownloadManager and FileProvider on Android Q (10)

targetSdkVersion: 30
In our App we have a feature, where we download files (mostly pdf) to the public download folder and start an intent afterwards to open it. Our code works fine for android apps with api >= 28 and >= 30. Just our app on Android 10 (sdkVersion 29) will try to open the document and instantly closes the activity that tried to display the pdf. The logcat shows following error:
22-03-17 14:23:42.486 12161-15168/? E/DisplayData: openFd: java.io.FileNotFoundException: open failed: EACCES (Permission denied)
22-03-17 14:23:42.486 12161-15168/? E/PdfLoader: Can't load file (doesn't open) Display Data [PDF : download.pdf] +ContentOpenable, uri: content://com.example.fileprovider/Download/download.pdf
If I grant the files permission in the app settings, it will work flawlessly but if I understood the android documentation correctly this should not be necessary since Android 10. Especially because there are no problems on Android 11 and Android 12 devices that do not have this permission. On all Android versions the file will be downloaded correctly and the user could manually open it from the download section of his device.
This is the Android Manifest section for the fileprovider
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/filepaths" />
</provider>
The filepaths XML file
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path
name="external_files"
path="." />
<external-path
name="Download"
path="Download/"/>
<files-path
name="files"
path="." />
<external-cache-path
name="external_cache"
path="." />
</paths>
This is the code with the DownloadManager usage to download the files
public static long downloadFile(Context context, String url, String fileName) {
DownloadManager downloadManager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
try {
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setTitle(fileName)
.setDescription(Localization.getStringClient("file_download_progress"))
.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName)
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
return downloadManager.enqueue(request);
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(context, Localization.getStringClient("error_downloading_asset"), Toast.LENGTH_SHORT).show();
}
return -1;
}
The broadcast receiver that listens on the download progress
public class DownloadBroadcastReceiver extends BroadcastReceiver {
private long downloadId = -2;
public void setDownloadId(long downloadId) {
this.downloadId = downloadId;
}
#Override
public void onReceive(Context context, Intent intent) {
long id = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
if (id == downloadId) {
DownloadManager downloadManager = (DownloadManager) context.getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(id);
Cursor c = downloadManager.query(query);
if (c != null) {
c.moveToFirst();
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
String uriString = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
String mediaType = c.getString(c.getColumnIndex(DownloadManager.COLUMN_MEDIA_TYPE));
Uri fileUri = Uri.parse(uriString);
DownloadUtils.openFile(context, fileUri, mediaType);
} else if (DownloadManager.STATUS_FAILED == c.getInt(columnIndex)) {
Toast.makeText(context, Localization.getStringClient("error_downloading_asset"), Toast.LENGTH_SHORT).show();
}
c.close();
}
}
}
}
The code to open the file. Only on Android 10 the app closes the activity instantly again.
public static void openFile(Context context, Uri fileUri, String mediaType) {
File file = new File(fileUri.getPath());
Uri uri = FileProvider.getUriForFile(
context,
context.getApplicationContext().getPackageName() + ".fileprovider",
file
);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, mediaType);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
context.startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
Toast.makeText(context, Localization.getStringClient("open_file_no_activity"), Toast.LENGTH_SHORT).show();
}
}
And a download call in the looks like this
#Override
public void startPDFDownload(String pdfDownloadUrl, String fileName) {
long downloadId = DownloadUtils.downloadFile(requireContext(), pdfDownloadUrl, fileName);
if (downloadId > -1) {
DownloadBroadcastReceiver receiver = new DownloadBroadcastReceiver();
receiver.setDownloadId(downloadId);
requireContext().registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}
}
I think I have a false understanding of how file handling works in Android 10 but I do not know where I have to adjust the code or configuration. Help is really appreciated. Currently as a workaround we ask for the permission for WRITE_EXTERNAL_STORAGE to open downloaded files on Android 10. But I would prefer to do it the right way.
Solution:
I adjusted the BroadcastReceiver to the following code. I removed the LOCAL_URI from the cursor and used the URI from the DownloadManager method.
public class DownloadBroadcastReceiver extends BroadcastReceiver {
private long downloadId = -2;
public void setDownloadId(long downloadId) {
this.downloadId = downloadId;
}
#Override
public void onReceive(Context context, Intent intent) {
long id = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
if (id == downloadId) {
DownloadManager downloadManager = (DownloadManager) context.getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(id);
Cursor c = downloadManager.query(query);
if (c != null) {
c.moveToFirst();
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
String mediaType = c.getString(c.getColumnIndex(DownloadManager.COLUMN_MEDIA_TYPE));
DownloadUtils.openFile(context, downloadManager.getUriForDownloadedFile(id), mediaType);
} else if (DownloadManager.STATUS_FAILED == c.getInt(columnIndex)) {
Toast.makeText(context, Localization.getStringClient("error_downloading_asset"), Toast.LENGTH_SHORT).show();
}
c.close();
}
}
}
}
And I adjusted the method to open the file with the uri to following code. I removed the FileProvider code and used the uri from the DownloadManager.
public static void openFile(Context context, Uri fileUri, String mediaType) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(fileUri, mediaType);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
context.startActivity(intent);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
Toast.makeText(context, Localization.getStringClient("open_file_no_activity"), Toast.LENGTH_SHORT).show();
}
}
The code of the other methods remains the same.

You should not use FileProvider to obtain an uri for your file.
You can get an uri from DownloadManager and use it to serve your file.
Code would be the same for all Android versions.
Not a single permission needed.

Android Image FIle variable is becoming null after image capture

The app I am currently developing has the feature of being able to capture an image, record a video, browse and upload a media file from gallery. Problem is, the app works well enough in emulator. Without any errors (checked with android 9+ emulators). But the app behaves unexpectedly while testing on physical device (Android 10). Unexpected, because, video recording and playing works fine, as well as browsing and uploading media from gallery. What fails is image capture. The thing is the image file is actually getting created, But I am getting the image file variable photoFile value as null in onActivityResult() method.
Here is the implementation:
manifest.xml
<provider android:name=".utils.MyFileProvider"
android:authorities="com.app.mtccrm.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external"
path="." />
<external-files-path
name="external_files"
path="." />
<cache-path
name="cache"
path="." />
<external-cache-path
name="external_cache"
path="." />
<files-path
name="files"
path="." />
</paths>
method to create image_file
public static File createImageFile(Context mContext, String name) throws IOException {
String imageFileName = name.replaceAll(" ", "_");
File storageDir = mContext.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = new File(storageDir + File.separator + imageFileName + ".png");
return image;
}
method responsible for opening the camera
private void openCamera() {
if (ActivityCompat.checkSelfPermission(AddNewFileActivity.this, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, REQUEST_PERMISSION_CODE_IMAGE);
} else {
Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try {
photoFile = CommonMethod.createImageFile(this, fileName);
} catch (IOException ioe) {
ioe.printStackTrace();
}
//Toast.makeText(this, ""+photoFile.getAbsolutePath(), Toast.LENGTH_SHORT).show();
if(photoFile != null ) {
Uri photoURI = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".fileprovider", photoFile);
captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
captureIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivityForResult(captureIntent, TAKE_PICTURE_CODE);
}else {
Toast.makeText(this, "Something went wrong while trying to create a file. Please try again", Toast.LENGTH_SHORT).show();
}
}
}
onActivityResult()
Toast.makeText(this, ""+photoFile, Toast.LENGTH_SHORT).show();
if (requestCode == TAKE_PICTURE_CODE && resultCode == RESULT_OK) {
if(photoFile == null) {
if(data != null) {
parseGalleryFile(data);
}
}else {
setImage(Uri.parse(photoFile.getAbsolutePath()));
}
}
The first Toast in onActivityResult() gives me null value. So somehow the photoFile variable is becoming null, however I am at a loss about the cause. Since, from the same activity using the same methods, recording of videos and browsing gallery works just fine. I thought it might have something to do with the activity getting paused when the camera is called. So, I added this
#Override
public void onSaveInstanceState(#NonNull Bundle outState, #NonNull PersistableBundle outPersistentState) {
super.onSaveInstanceState(outState, outPersistentState);
Toast.makeText(this, ""+photoFile, Toast.LENGTH_SHORT).show();
if(photoFile != null) {
outState.putString("FileId", photoFile.getAbsolutePath());
}
}
#Override
protected void onRestoreInstanceState(#NonNull Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
Toast.makeText(this, ""+savedInstanceState.getString("FileId"), Toast.LENGTH_SHORT).show();
if(savedInstanceState.getString("FileId") != null) {
if (photoFile == null) {
photoFile = new File(savedInstanceState.getString("FileId"));
}
}
}
Unfortunately, save and restore state methods are not getting called, so that means the activity is not being paused. So what could be the cause for photofile becoming null? what exactly am I doing wrong?
Thanks for the help.

How to retrieve and open PDF file saved to downloads through MediaStore API in Android?

I am downloading a PDF file from a server and passing the response body bytestream into the function below, which is storing the PDF file successfully in the user downloads folder.
#RequiresApi(Build.VERSION_CODES.Q)
fun saveDownload(pdfInputStream: InputStream) {
val values = ContentValues().apply {
put(MediaStore.Downloads.DISPLAY_NAME, "test")
put(MediaStore.Downloads.MIME_TYPE, "application/pdf")
put(MediaStore.Downloads.IS_PENDING, 1)
}
val resolver = context.contentResolver
val collection = MediaStore.Downloads.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
val itemUri = resolver.insert(collection, values)
if (itemUri != null) {
resolver.openFileDescriptor(itemUri, "w").use { parcelFileDescriptor ->
ParcelFileDescriptor.AutoCloseOutputStream(parcelFileDescriptor)
.write(pdfInputStream.readBytes())
}
values.clear()
values.put(MediaStore.Downloads.IS_PENDING, 0)
resolver.update(itemUri, values, null, null)
}
}
Now once this function returns I want to open the saved PDF file. I've tried several ways to get this to work but the pickers always say that there is nothing to open the file. I think that there is either still a permissions issue going on (maybe I'm using the FileProvider wrong?), or perhaps the path is wrong, or it could be something else entirely.
Here's a couple of examples of what I've tried:
fun uriFromFile(context: Context, file: File): Uri {
return FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file)
}
a)
val openIntent = Intent(Intent.ACTION_VIEW)
openIntent.putExtra(Intent.EXTRA_STREAM, uriFromFile(this, File(this.getExternalFilesDir(DIRECTORY_DOWNLOADS)?.absolutePath.toString(), "test")))
openIntent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
openIntent.type = "application/pdf"
startActivity(Intent.createChooser(openIntent, "share.."))
b)
val shareIntent = Intent(Intent.ACTION_SEND)
shareIntent.putExtra(Intent.EXTRA_STREAM, uriFromFile(this, File(this.getExternalFilesDir(null)?.absolutePath.toString(), "test.pdf")))
shareIntent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
shareIntent.type = "application/pdf"
startActivity(Intent.createChooser(shareIntent, "share.."))
c)
val file = File(itemUri.toString()) //itemUri from the saveDownload function
val target = Intent(Intent.ACTION_VIEW)
val newFile = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", file);
target.setDataAndType(newFile, "application/pdf")
target.flags = Intent.FLAG_ACTIVITY_NO_HISTORY
val intent = Intent.createChooser(target, "Open File")
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
ContextCompat.startActivity(this, intent, null)
d)
val target = Intent(Intent.ACTION_VIEW)
target.setDataAndType(Uri.parse("content://media/external_primary/downloads/2802"), "application/pdf"
target.flags = Intent.FLAG_ACTIVITY_NO_HISTORY
val intent = Intent.createChooser(target, "Open File")
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
ContextCompat.startActivity(this, intent, null)
(also tried /test.pdf on the end of this URI, and replacing media with my authority name)
I have also added this to my manifest file within the application tags:
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths" />
</provider>
#xml/provider_paths is as follows, although I have tried various combinations in addition to this including the paths as ".":
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path name="files_root" path="/"/>
<files-path name="files_root" path="/"/>
<external-path name="files_root" path="/"/>
</paths>
As a side note, there is definitely pickers available capable of opening PDFs, and going into the file explorer and opening it from there works fine. When attempting to share instead of opening the sharing also fails.

Follow this step and code, it will manage everything from downloading your pdf and opening it.
Create a class name as DownloadTask and put the complete code given below
public class DownloadTask {
private static final String TAG = "Download Task";
private Context context;
private String downloadFileUrl = "", downloadFileName = "";
private ProgressDialog progressDialog;
long downloadID;
private BroadcastReceiver onDownloadComplete = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
//Fetching the download id received with the broadcast
long id = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
//Checking if the received broadcast is for our enqueued download by matching download id
if (downloadID == id) {
downloadCompleted(downloadID);
}
}
};
public DownloadTask(Context context, String downloadUrl) {
this.context = context;
this.downloadFileUrl = downloadUrl;
downloadFileName = downloadFileUrl.substring(downloadFileUrl.lastIndexOf('/') + 1);//Create file name by picking download file name from URL
Log.e(TAG, downloadFileName);
context.registerReceiver(onDownloadComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
downloadFile(downloadFileUrl);
}
public void downloadFile(String url) {
try {
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).getAbsolutePath(), downloadFileName);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url))
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)// Visibility of the download Notification
.setDestinationInExternalPublicDir(
Environment.DIRECTORY_DOWNLOADS,
downloadFileName
)
.setDestinationUri(Uri.fromFile(file))
.setTitle(downloadFileName)// Title of the Download Notification
.setDescription("Downloading")// Description of the Download Notification
.setAllowedOverMetered(true)// Set if download is allowed on Mobile network
.setAllowedOverRoaming(true);// Set if download is allowed on roaming network
request.allowScanningByMediaScanner();
DownloadManager downloadManager = (DownloadManager) context.getSystemService(DOWNLOAD_SERVICE);
downloadID = downloadManager.enqueue(request);// enqueue puts the download request in the queue.
progressDialog = new ProgressDialog(context);
progressDialog.setMessage("Downloading...");
progressDialog.setCancelable(false);
progressDialog.show();
} catch (Exception e) {
Log.d("Download", e.toString());
}
}
void downloadCompleted(long downloadID) {
progressDialog.dismiss();
new AlertDialog.Builder(context)
.setTitle("Document")
.setMessage("Document Downloaded Successfully")
.setPositiveButton("Open", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
openDownloadedAttachment(downloadID);
}
})
// A null listener allows the button to dismiss the dialog and take no further action.
.setNegativeButton(android.R.string.no, null)
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
context.unregisterReceiver(onDownloadComplete);
}
Uri path;
private void openDownloadedAttachment(final long downloadId) {
DownloadManager downloadManager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(downloadId);
Cursor cursor = downloadManager.query(query);
if (cursor.moveToFirst()) {
int downloadStatus = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS));
String downloadLocalUri = cursor.getString(cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
String downloadMimeType = cursor.getString(cursor.getColumnIndex(DownloadManager.COLUMN_MEDIA_TYPE));
if ((downloadStatus == DownloadManager.STATUS_SUCCESSFUL) && downloadLocalUri != null) {
path = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", new File(Uri.parse(downloadLocalUri).getPath()));
//path = Uri.parse(downloadLocalUri);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, downloadMimeType);
pdfIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
context.startActivity(pdfIntent);
} catch (ActivityNotFoundException e) {
Toast.makeText(context, "No Application available to view PDF", Toast.LENGTH_SHORT).show();
}
}
}
cursor.close();
}
}
And then download your pdf like this from your activity.
new DownloadTask(this, "PDF_URL");
And from your fragment
new DownloadTask(getContext(), "PDF_URL");
After download completed it will open your pdf automatically.

According to Android Developer, MediaStore isn't being used for accessing non-media files such as pdf files:
If your app works with documents and files that don't exclusively
contain media content, such as files that use the EPUB or PDF file
extension, use the ACTION_OPEN_DOCUMENT intent action, as described in
the guide on how to store and access documents and other files.
Moreover, there isn't any official solution to access non-media files by means of using Cursor and Content Provider. However, there is an official and clean code approach which I've tested it on Android 11 and worked as expected. here is:
public class retrieve_pdf_file {
#RequiresApi(Build.VERSION_CODES.Q)
public static void get(Activity activity) {
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("application/pdf");
// Optionally, specify a URI for the file that should appear in the
// system file picker when it loads.
intent.putExtra(DocumentsContract.EXTRA_INITIAL_URI, MediaStore.Downloads.EXTERNAL_CONTENT_URI);
activity.startActivityForResult(intent, main_activity.PICK_PDF_FILE);
}
public static void get(Activity activity, String filename) { // filename is used for lower that API level 29
// older that API level 29 approaches
File file = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
// TODO
}
}
And also, to get the selected pdf file's Uri you must listen for the activity's result:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent resultData) {
if (requestCode == PICK_PDF_FILE && resultCode == Activity.RESULT_OK) {
System.out.println("request code: PICK_PDF_FILE && result code: OK");
// The result data contains a URI for the document or directory that
// the user selected.
Uri uri = null;
if (resultData != null) {
uri = resultData.getData();
// Perform operations on the document using its URI.
System.out.println(uri);
} else {
System.out.println("resultData is null");
}
} else {
System.out.println("result code: NOT OK");
}
}
This is the official solution that can be found in Android Developer for API level 29 or higher.

Here is the code that i use to open doc file with Uri.
fun viewPDFIntent(fileUri: Uri?, context: Context, title: String?, type: String) {
val viewPDFIntent = Intent(Intent.ACTION_VIEW).apply {
setDataAndType(fileUri, type)
flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
}
context.startActivity(Intent.createChooser(viewPDFIntent, title))
}
Here type for pdf is "application/pdf".
You are getting created pdf uri in itemUri variable, pass this to first argument of this function.

Android Application Crashes while Capturing Full Size Picture

I am developing an Android Application that takes a picture and saves a full-size picture onto the device. I have mostly taken help from developers android site. When I run my code and try to take the picture the application crashes instantly. The code I am using is as follows:
static final int REQUEST_IMAGE_CAPTURE = 1;
static final int REQUEST_TAKE_PHOTO = 1;
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
System.out.println("Error in Dispatch Take Picture Intent");
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
//Bundle extras = data.getExtras();
//Bitmap imageBitmap = (Bitmap) extras.get("data");
//imageView.setImageBitmap(imageBitmap);
Toast.makeText(getApplicationContext(),"Working",Toast.LENGTH_LONG).show();
}
}
String currentPhotoPath;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
currentPhotoPath = image.getAbsolutePath();
return image;
}
private View.OnClickListener onCamClick() {
return new View.OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("Starting Camera Activity");
//dispatchTakePictureIntent();
//Toast.makeText(getApplicationContext(),"Working",Toast.LENGTH_LONG).show();
dispatchTakePictureIntent();
}
};
}
When I run my code I get the following error:

Please advise regarding this matter.

Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
Here, you are saying that the authority string for your FileProvider is com.example.android.fileprovider. Based on the error, that is not what you have on the <provider> element in the manifest.

add this in your manifest.xml (after ):
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="android.getqardio.com.gmslocationtest"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
Create provider_paths on Resources/xml, and add this content:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<files-path
name="share"
path="external_files"/>
</paths>
Activity:
File imagePath = new File(getFilesDir(), "external_files");
imagePath.mkdir();
File imageFile = new File(imagePath.getPath(), "test.jpg");
// Write data in your file
Uri uri = FileProvider.getUriForFile(this, getPackageName(), imageFile);
Intent intent = ShareCompat.IntentBuilder.from(this)
.setStream(uri) // uri from FileProvider
.setType("text/html")
.getIntent()
.setAction(Intent.ACTION_VIEW) //Change if needed
.setDataAndType(uri, "image/*")
.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);

FileProvider not working

What I am trying to do is to get a file that is in the private area to be opened by another program. In this example, a image viewer app.
AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.mydomain.myapp"
android:exported="false"

This always results in a toast message "Unable to find item". What am I doing wrong and how to resolve this?

What am I doing wrong
File file = new File(context.getApplicationInfo().dataDir + File.separator + "cache" + File.separator + filename);
Use getCacheDir() to get the cache directory, as your approach is not going to be reliable for secondary accounts on Android 4.2+ tablets and Android 5.0+ phones. So, this should be:
File file = new File(context.getCacheDir(), filename);
Then, you need to replace Uri.fromFile(file) with a call to getUriForFile() on FileProvider, as is covered in the documentation. What you presently have is a Uri pointing to a file, not pointing to a ContentProvider, let alone your FileProvider implementation.
Finally, you will need to call addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION) on the Intent before you use it with startActivity(), as otherwise the app that responds to the startActivity() request will not have access to the content.
This sample app demonstrates a working implementation of a FileProvider.
