Download a PDF and open with Acrobat Reader - java

I just try to play with the PRDownloader class to get a PDF from the Internet.
This works good in the VDI (I see the file in the Device File Explorer).
But now I want to test this on a real Android phone and let the Acrobat Reader open the PDF.
I use "getFilesDir()" as path to save the document, this seems to work (file.exist()).
But when I start an Intent to open this file with a PDF Viewer, the Acrobar Reader opens very short and reports (as a Toast) "Cannot access this file".
I use "file.setReadable(true,false)" to set the rights, and I see (also on the read device) the rights "-rw-r--r--" to the file.
How/where to set the rights for other applications to read this file/folder?
Thanks
Steffen

I use this code in "MainActivity::onDownloadComplete" ('String fname' is the complete filename)
String fname = getContext().getFilesDir().getPath() + File.separator + "download.pdf";
....
File file = new File(fname);
String ext = file.getName().substring(file.getName().lastIndexOf(".") + 1);
MimeTypeMap mime = MimeTypeMap.getSingleton();
String type = mime.getMimeTypeFromExtension(ext);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(fname), type);
file.setReadable(true, false);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
I also tried to save to file to download folder, but this (also) failed (no file was written):
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString()
--[2021-03-02 07:20]--
I extracted and merge all the code to another button onClick:
public void onClick(View v) {
String url = "https://www.antennahouse.com/hubfs/xsl-fo-sample/pdf/basic-link-1.pdf";
String dir = getContext().getFilesDir().getPath();
String bname = "download.pdf";
int downloadId = PRDownloader.download(url, dir, bname)
.build()
.start(new OnDownloadListener() {
#Override
public void onDownloadComplete() {
try {
File file = new File(dir + File.separator + bname);
String ext = file.getName().substring(file.getName().lastIndexOf(".") + 1);
MimeTypeMap mime = MimeTypeMap.getSingleton();
String type = mime.getMimeTypeFromExtension(ext);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), type);
file.setReadable(true, false);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
catch (FileUriExposedException e) {
Log.e("Download", e.toString());
}
}
#Override
public void onError(Error error) {
}
});

Install app automatically in android 7 or higher

I want to install app in my projects.
But my code don't work in api 24 or higher.
What is its solution?
My code is:
String timestamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());
String dir = Environment.getExternalStorageDirectory() + "/" + context.getResources().getString(R.string.cache_path);
String appName = appModel.getAppUrl().substring(appModel.getAppUrl().lastIndexOf('/') + 1, appModel.getAppUrl().length());
appName = timestamp + "_" + appName;
private void appInstaller(String dir, String appName) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
File file = new File(dir, appName);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
startActivity(intent);
} else {
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/" + dir + "/" + appName)), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
Manifest:
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
This question is like my question. But does not work its solution for me!
Thanks about to help me!
I resolved this problem and this way is true for me:
First:
private static final String APP_DIR = Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyAppFolderInStorage/";
private void install() {
File file = new File(APP_DIR + fileName);
if (file.exists()) {
Intent intent = new Intent(Intent.ACTION_VIEW);
String type = "application/vnd.android.package-archive";
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Uri downloadedApk = FileProvider.getUriForFile(getContext(), "ir.greencode", file);
intent.setDataAndType(downloadedApk, type);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
} else {
intent.setDataAndType(Uri.fromFile(file), type);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
getContext().startActivity(intent);
} else {
Toast.makeText(getContext(), "ّFile not found!", Toast.LENGTH_SHORT).show();
}
}
Second: For android 7 and above you should define a provider in manifest like below!
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="ir.greencode"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/paths" />
</provider>
Third: Define path.xml in res/xml folder like below! I'm using this path for internal storage if you want to change it to something else there is a few way! You can go to this FileProvider
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="your_folder_name" path="MyAppFolderInStorage/"/>
</paths>
Forth: You should add this permission in manifest:
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>

java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/

EDIT:Ok I have tried the suggestions and changed it to getExternalFilesDir() and am still getting the same error. Skip to the bottom where it says "EDITED CODE" to see what it is now. I also changed it so that the screenshot will save to the pictures directory instead of creating a new directory. (END EDIT)
I have an android app that contains a recyclerview. I have created a button that will export create a PNG of the recyclerview data, save it to the device, and then send it as an attachment to the email application so it can be emailed. I'm getting the exception " java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/ExportedFlares/FlareData.png"
Here is the code for the function that saves the bitmap to the device:
private void saveBitmap(Bitmap bitmap){
if(bitmap!=null){
try {
FileOutputStream outputStream = null;
try {
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +
"/ExportedFlares";
File dir = new File(file_path, "FlareData");
if(!dir.exists())
dir.mkdirs();
outputStream = new FileOutputStream(dir); //here is set your file path where you want to save or also here you can set file object directly
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream); // bitmap is your Bitmap instance, if you want to compress it you can compress reduce percentage
// PNG is a lossless format, the compression factor (100) is ignored
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (outputStream != null) {
outputStream.flush();
outputStream.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
And here is the onClick code for when the button is tapped:
public void onClick(View v) {
saveBitmap(getScreenshotFromRecyclerView(recyclerView));
String filename = "FlareData.png";
File fileLocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +
"/ExportedFlares", filename);
Uri path = FileProvider.getUriForFile(FlareActivity.this, BuildConfig.APPLICATION_ID + ".provider",fileLocation);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
emailIntent .setType("vnd.android.cursor.dir/email");
String to[] = {"email#gmail.com"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
startActivity(Intent.createChooser(emailIntent , "Send email..."));
The final line of the following code is what is throwing the exception:
File fileLocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +
"/ExportedFlares", filename);
Uri path = FileProvider.getUriForFile(FlareActivity.this, BuildConfig.APPLICATION_ID + ".provider",fileLocation);
Here is the XML data, I have provider_paths.xml here:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-files-path name="FlareData.png" path="ExportedFlares/"/>
</paths>
And this is from the manifest:
enter code here
<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>
EDITED CODE:
emailFlaresButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Context context = getApplicationContext();
saveBitmap(context, getScreenshotFromRecyclerView(recyclerView));
String filename = "FlareData.png";
File fileLocation = new File(context.getExternalFilesDir(DIRECTORY_PICTURES).getAbsolutePath()
, filename);
Uri path = FileProvider.getUriForFile(FlareActivity.this, BuildConfig.APPLICATION_ID + ".provider",fileLocation);
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
emailIntent .setType("vnd.android.cursor.dir/email");
String to[] = {"asd#gmail.com"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
startActivity(Intent.createChooser(emailIntent , "Send
email..."));
// Intent intent = new Intent(FlareActivity.this,
AddFlareActivity.class);
//startActivityForResult(intent, ADD_FLARE_RESULT_CODE);
}
});
And here is the piece of code that the error is pointing to (the last line) :
Uri path = FileProvider.getUriForFile(FlareActivity.this, BuildConfig.APPLICATION_ID + ".provider",fileLocation);
I have tried it with the provider path being set to both external-files-path and external-path and it doesn't affect the issue

Change external-files-path to external-path.
Or, put your files in getExternalFilesDir() (called on a Context). This is the better solution, as your current code will not work on Android Q (by default) and Android R+ (for all apps).

Save downloaded file in public Downloads directory and open it with intent

I am having trouble downloading and opening a file.
I successfully download the file in device's public external Download folder and I can open it through File Explorer, but when I want to open it with intent right after the download has finished from my app, java.lang.IllegalArgumentException occurs:
Caused by: java.lang.IllegalArgumentException: Failed to find configured root that contains /file:/storage/emulated/0/Download/Colors.pdf

MainActivity.java:97 is
Uri uri = FileProvider.getUriForFile(MainActivity.this,
BuildConfig.APPLICATION_ID+".provider",
new File(filePath));
I tried to implement FileProvider, but I can't figure out how to make it work with public directories. Also when I do the "hack" with removing StrictMode, the file opens. Here's my code:
#Override
public void onDownloadPrepared(Request downloadRequest, String fileName) {
downloadRequest.allowScanningByMediaScanner();
downloadRequest.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS,
fileName);
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
if (manager == null) return;
long id = manager.enqueue(downloadRequest);
BroadcastReceiver downloadReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
long receivedId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID,
-1);
if (id == receivedId) {
Query query = new Query();
query.setFilterById(id);
Cursor cursor = manager.query(query);
if (cursor.moveToFirst()) {
int columnIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == cursor.getInt(columnIndex)) {
String filePath = cursor.getString(
cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
Intent intent1 = new Intent(Intent.ACTION_VIEW);
Uri uri = FileProvider.getUriForFile(MainActivity.this,
BuildConfig.APPLICATION_ID+".provider",
new File(filePath));
intent1.setData(uri);
intent1.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent1);
}
}
unregisterReceiver(this);
}
}
};
IntentFilter filter = new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE);
registerReceiver(downloadReceiver, filter);
}
<paths>
<external-path name="external_files" path="."/>
</paths>
<provider
android:name="android.support.v4.content.FileProvider"

android:exported="false"
android:grantUriPermissions="true">

</provider>
Remove the "file" prefix from the path:
filePath = filePath.replace("file:/","");

The Download folder is not listed as a path, supported by your FileProvider.
Try adding the following to the provider_path.xml:

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"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/path" />
</provider>
/res/xml/path.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="cache" path="cache/"/>
</paths>
Java code (file location)
File file = new File(context.getApplicationInfo().dataDir + File.separator + "cache" + File.separator + filename);
Java code (open file)
if(file != null && file.isFile() && file.canRead() && file.length() > 0){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
List<ResolveInfo> resInfoList = this.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
Uri uri = Uri.parse(file.toURI().toString());
for (int i = 0; i < resInfoList.size(); i++) {
try{
ResolveInfo resolveInfo = resInfoList.get(i);
String packageName = resolveInfo.activityInfo.packageName;
grantUriPermission(packageName, uri, Intent.FLAG_GRANT_READ_URI_PERMISSION);
}catch(Exception e){
}catch(Error e){
}
}
MimeTypeMap myMime = MimeTypeMap.getSingleton();
Intent newIntent = new Intent(Intent.ACTION_VIEW);
String mimeType = myMime.getMimeTypeFromExtension(".jpg");
newIntent.setDataAndType(Uri.fromFile(file), mimeType);
newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
try {
context.startActivity(newIntent);
return true;
} catch (Exception e) {
}
}
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.

Android sharing Files, by sending them via email or other apps

I have a list of files in my android app and I want to be able to get the selected items and send them via email or any other sharing app. Here is my code.
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_EMAIL, getListView().getCheckedItemIds());
sendIntent.setType("text/plain");
startActivity(sendIntent);
this is the code for sharing file in android
Intent intentShareFile = new Intent(Intent.ACTION_SEND);
File fileWithinMyDir = new File(myFilePath);
if(fileWithinMyDir.exists()) {
intentShareFile.setType("application/pdf");
intentShareFile.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+myFilePath));
intentShareFile.putExtra(Intent.EXTRA_SUBJECT,
"Sharing File...");
intentShareFile.putExtra(Intent.EXTRA_TEXT, "Sharing File...");
startActivity(Intent.createChooser(intentShareFile, "Share File"));
}
Below is another method to share PDF file if you have put file provider in manifest
Uri pdfUri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
pdfUri = FileProvider.getUriForFile(PDFViewerActivity.this, fileprovider, pdfFile);
} else {
pdfUri = Uri.fromFile(pdfFile);
}
Intent share = new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType("application/pdf");
share.putExtra(Intent.EXTRA_STREAM, pdfUri);
startActivity(Intent.createChooser(share, "Share file"));
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(exportPath));
also you can make zip file of all file and attach zip file for send multiple file in android
For those who trying in Kotlin here is the way:
Start the intent like below:
fun startFileShareIntent(filePath: String) { // pass the file path where the actual file is located.
val shareIntent = Intent(Intent.ACTION_SEND).apply {
type = FILE_TYPE // "*/*" will accepts all types of files, if you want specific then change it on your need.
flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
putExtra(
Intent.EXTRA_SUBJECT,
"Sharing file from the AppName"
)
putExtra(
Intent.EXTRA_TEXT,
"Sharing file from the AppName with some description"
)
val fileURI = FileProvider.getUriForFile(
context!!, context!!.packageName + ".provider",
File(filePath)
)
putExtra(Intent.EXTRA_STREAM, fileURI)
}
startActivity(shareIntent)
}
In Manifest inside the application tag:
<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>
Under res-->xml--> provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
<files-path name="files" path="." />
<external-path name="external_files" path="."/>
</paths>
This is work for every single file!
private void shareFile(File file) {
Intent intentShareFile = new Intent(Intent.ACTION_SEND);
intentShareFile.setType(URLConnection.guessContentTypeFromName(file.getName()));
intentShareFile.putExtra(Intent.EXTRA_STREAM,
Uri.parse("file://"+file.getAbsolutePath()));
//if you need
//intentShareFile.putExtra(Intent.EXTRA_SUBJECT,"Sharing File Subject);
//intentShareFile.putExtra(Intent.EXTRA_TEXT, "Sharing File Description");
startActivity(Intent.createChooser(intentShareFile, "Share File"));
}
Thanks Tushar-Mate!
First you should define File Provider, see https://medium.com/#ali.dev/open-a-file-in-another-app-with-android-fileprovider-for-android-7-42c9abb198c1.
The code checks that a device contains applications which can receive the file, see How to check if an intent can be handled from some activity?.
fun sharePdf(file: File, context: Context) {
val uri = getUriFromFile(file, context)
if (uri != null) {
val intent = Intent().apply {
action = Intent.ACTION_SEND
type = "application/pdf" // For PDF files.
putExtra(Intent.EXTRA_STREAM, uri)
putExtra(Intent.EXTRA_SUBJECT, file.name)
putExtra(Intent.EXTRA_TEXT, file.name)
// Grant temporary read permission to the content URI.
addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
}
// Validate that the device can open your File.
val activityInfo = intent.resolveActivityInfo(context.packageManager, intent.flags)
if (activityInfo?.exported == true) {
context.startActivity(Intent.createChooser(intent,
"Share PDF file")
}
}
}
fun getUriFromFile(file: File, context: Context): Uri? =
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Uri.fromFile(file)
} else {
try {
FileProvider.getUriForFile(context, context.packageName + ".provider", file)
} catch (e: Exception) {
throw if (e.message?.contains("ProviderInfo.loadXmlMetaData") == true) {
Error("FileProvider is not set or doesn't have needed permissions")
} else {
e
}
}
}
Use ACTION_SEND_MULTIPLE for delivering multiple data to someone
intent.setAction(Intent.ACTION_SEND_MULTIPLE);
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, arrayUri);
intent.setType("text/plain");
startActivity(intent);
The arrayUri is the Array List of Uri of files to Send.
Here is an example to share or save a text file:
private void shareFile(String filePath) {
File f = new File(filePath);
Intent intentShareFile = new Intent(Intent.ACTION_SEND);
File fileWithinMyDir = new File(filePath);
if (fileWithinMyDir.exists()) {
intentShareFile.setType("text/*");
intentShareFile.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + filePath));
intentShareFile.putExtra(Intent.EXTRA_SUBJECT, "MyApp File Share: " + f.getName());
intentShareFile.putExtra(Intent.EXTRA_TEXT, "MyApp File Share: " + f.getName());
this.startActivity(Intent.createChooser(intentShareFile, f.getName()));
}
}
File directory = new File(Environment.getExternalStorageDirectory() + File.separator + BuildConfig.APPLICATION_ID + File.separator + DIRECTORY_VIDEO);
String fileName = mediaModel.getContentPath().substring(mediaModel.getContentPath().lastIndexOf('/') + 1, mediaModel.getContentPath().length());
File fileWithinMyDir = new File(directory, fileName);
if (fileWithinMyDir.exists()) {
Uri fileUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", fileWithinMyDir);
Intent intent = ShareCompat.IntentBuilder.from(this)
.setStream(fileUri) // uri from FileProvider
.setType("text/html")
.getIntent()
.setAction(Intent.ACTION_SEND) //Change if needed
.setDataAndType(fileUri, "video/*")
.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
val uriArrayList: ArrayList<Uri> = ArrayList()
GlobalScope.launch(Dispatchers.IO) {
runCatching {
itemsList!!.forEach {
uriArrayList.add(
FileProvider.getUriForFile(
mContext,
APPLICATION_ID + ".provider",
File(it.path)
)
)
}
}.onSuccess {
requireActivity().runOnUiThread {
if (uriArrayList.size > 0) {
val intent = Intent()
intent.action = Intent.ACTION_SEND_MULTIPLE
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uriArrayList)
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
intent.type = "image/*|application/pdf/*"
startActivity(Intent.createChooser(intent, resources.getString(R.string.share)))
}
}
}
.onFailure {
Log.e("SHARING_FAILED", it)
}
}
First of all you have to write provider code in app manifest file for sharing on android 7.0 and above
<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>
here provider_paths are:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="/storage/emulated/0" path="."/>
<root-path name="root" path="." />
<files-path name="files" path="."/>
</paths>
