Can't set imageview from Uri - java

In the MainActivity I take a picture from camera as the official documentation show:
private void dispatchTakePictureIntent() {
if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_PERMISSION_CAMERA);
} else {
if (Build.VERSION.SDK_INT >= 24) {
try {
Method m = StrictMode.class.getMethod("disableDeathOnFileUriExposure");
m.invoke(null);
} catch (Exception e) {
e.printStackTrace();
}
}
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
}
// Continue only if the File was successfully created
if (photoFile != null) {
photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, 2);
}
}
}
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
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
Then I save the photo to the gallery:
private Uri galleryAddPic() {
try{
file = new File(mCurrentPhotoPath);
MediaStore.Images.Media.insertImage(getContentResolver(),
file.getAbsolutePath(), file.getName(), null);
this.sendBroadcast(new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(file)));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Log.v("UriTaken", Uri.fromFile(file).toString());
return Uri.fromFile(file);
}
Then, with putExtra, I pass to the next activity the Uri of the file.
The uri is this:
file:///storage/emulated/0/Android/data/com.my.name.myappname/files/Pictures/JPEG_20181231_002549_9133887087473873179.jpg
In the new activity, I retrieve the uri, and before I set the imageview with it(if I use image.setImageURI(imageUri); it works), I want to rotate the image to the exact orientation(I don't know why in the image view is always rotated).
I use this code:
if (getIntent().getExtras() != null) {
imageUri = Uri.parse(getIntent().getStringExtra("uri"));
path = getPath(imageUri);
try {
//filePath = getFileName(path);
ExifInterface exifInterface = new ExifInterface(path);
int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_UNDEFINED);
Bitmap bitmap = BitmapFactory.decodeFile(path);
Bitmap rotatedBitmap = null;
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
rotatedBitmap = rotateImage(bitmap, 90);
image.setImageBitmap(rotatedBitmap);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotatedBitmap = rotateImage(bitmap, 180);
image.setImageBitmap(rotatedBitmap);
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotatedBitmap = rotateImage(bitmap, 270);
image.setImageBitmap(rotatedBitmap);
break;
case ExifInterface.ORIENTATION_NORMAL:
image.setImageBitmap(bitmap);
default:
rotatedBitmap = bitmap;
image.setImageBitmap(rotatedBitmap);
}
} catch (IOException e) {
Log.w("TAG", "-- Error in setting image");
}
And here the method that cause the crash:
public String getPath(Uri imageUri) {
String wholeId = DocumentsContract.getDocumentId(imageUri);
String id = wholeId.split(":")[1];
String[] column = {MediaStore.Images.Media.DATA};
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = getContentResolver().
query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, new String[]{id}, null);
filePath = "";
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
cursor.close();
return filePath;
}
On the first line of the method I got the error posted above, invalid uri: file///storage........etc
If I get the picture from gallery it works, because i get this Uri:
content://com.android.providers.media.documents/document/image%3A97897
I don't know if the problem is in the method that saves the image in the MainActivity or is in the getPath() method. What I need to do is to take a picture, save to the gallery and retrieve in the next activity.

How do I properly compress an image and get the URI?

I'm trying to put the URIs of both the image and the thumbnail from a camera intent into a SQLite database.
I have the full image inserting just fine. I thought I had the thumbnail going in too but it's actually still the full image going into the database again.
Can I get a bit of guidance on how to go about doing this? I've tried a number of things so far but have been stuck for a couple days on this step.
Here are my relevant methods:
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;
File photoThumbnailFile = null;
try {
photoFile = createImageFile();
photoThumbnailFile = createImageThumbnailFile();
} catch (IOException ex) {
}
// Continue only if the File was successfully created
if (photoFile != null) {
photoURI = FileProvider.getUriForFile(this,
"com.example.jeremy.sqlwine.fileprovider",
photoFile);
photoThumbnailURI = FileProvider.getUriForFile(this,
"com.example.jeremy.sqlwine.fileprovider",
photoThumbnailFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
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
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
private File createImageThumbnailFile() throws IOException {
// Create an image thumbnail file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageThumbnailFileName = "THUMBNAIL_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageThumbnailFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoThumbnailPath = image.getAbsolutePath();
return image;
}
//This method will happen when the camera is done taking the picture
#Override

OnActivityResult: Uri and getData is a null object during capture a photo

I have a problem with Uri object. User should take a photo and next this is sending to Firebase Storage. But sth is wrong with onActivityResult.
I read a lot of topics (https://developer.android.com/training/camera/photobasics.html, StackOverFlow too) but nothing works with this code.
There is an error:
Attempt to invoke virtual method 'java.lang.String android.net.Uri.getLastPathSegment()' on a null object reference
Below is a code:
mUploadBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, CAMERA_REQUEST_CODE);
}
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK && data != null) {
mProgress.setMessage("Uploading Image...");
mProgress.show();
Uri uri = data.getData();
StorageReference filepath = mStorage.child("Photos").child(uri.getLastPathSegment());
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
mProgress.dismiss();
Uri downloadUri = taskSnapshot.getDownloadUrl();
Picasso.with(MainActivity.this).load(downloadUri).fit().centerCrop().into(mImageView);
Toast.makeText(MainActivity.this, "Upload Done.", Toast.LENGTH_LONG).show();
}
});
}
}
}
As I checked, data (Intent) in onActivityResult is equal to NULL, so uri is null as well.
So, how can I resolve this challenge and make it usable? Should I use a Bitmap to have an access to a photo?
Could someone help me to resolve this situation?
Regards
I figured out with my question.
It works at now.
private ProgressDialog mProgress;
private Button mUploadBtn;
private ImageView mImageView;
Uri picUri;
private StorageReference mStorage;
private static final int CAMERA_REQUEST_CODE = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mStorage = FirebaseStorage.getInstance().getReference();
mUploadBtn = (Button) findViewById(R.id.uploadBtn);
mImageView = (ImageView) findViewById(R.id.imageView);
mProgress = new ProgressDialog(this);
mUploadBtn.setOnClickListener(new View.OnClickListener() {
#Override

Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File file=getOutputMediaFile(1);
picUri = Uri.fromFile(file); // create

startActivityForResult(i, CAMERA_REQUEST_CODE);
}
});
}

}
}
Always create your file and store the captured image using the path as follows
File photoFile = null;
mUploadBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(getPackageManager()) != null) {
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
startActivityForResult(takePictureIntent, CAMERA_REQUEST_CODE);
}
}
});
}
private File createImageFile() throws IOException {
// Create an image mSelectedFile name
String timeStamp = new SimpleDateFormat(Constants.PHOTO_DATE_FORMAT, Locale.ENGLISH).format(new Date());
String imageFileName = "IMG_" + timeStamp;
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File file = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
return file;
}
Then use this file "photoFile" and use it as needed in onActivityResult.
I faced the same problem before so i made sure that i check everything i can check when onActivityResult is called below is my code.
First i use this intent to capture image
File photoFile;

}
if (photoFile != null)
{

startActivityForResult(takePhotoIntent, CAMERA_REQUEST_CODE);

after this process i always ended having a bitmap to use it as i want.
For Get Actual Image predefined path of Captured Image using
Intent cameraIntent = new Intent(

cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
this.startActivityForResult(cameraIntent, 101);
After Captured Image you can get Captured Image on path which is set in cameraIntent. If you don't Want to set predefined path then check Intent data.
if (resultCode == android.app.Activity.RESULT_OK && requestCode == 101) {
try {

app crashing after taking a pic on samsung phones only

I am developing an Android app in which the user can select a picture from the gallery or can click a photo through the phone's camera and save in the app's folder called FiZZ. The camera part of app runs perfectly fine on all android phones except Samsung.The code given below throws a NullPointerException at image.setPath(fileUri.getPath()); and crashes.

e.printStackTrace();
}
}
else
{
photo2Uri = selectedImageUri;
try {
Bitmap bitmap = Utilities.decodeSampledBitmap(Utilities.readBytes(selectedImageUri, mContext), 100, 100)
;
myQuestion.setRightThumbnail(Utilities.decodeBitmapToArray(bitmap));
photo2.setImageBitmap(bitmap);
} catch (IOException e) {
Utilities.displayAlert("Oops!", e.getMessage(), mContext);
e.printStackTrace();
}
}
}
}
}
In my code S2 Enters in this
if(data == null)
{
isCamera = true;
}
While HTC goes here
isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
The result isCamera is false. so it tries to run
selectedImageUri = data == null ? null : data.getData();
which gives null
What could be solution, how can i retrieve image from camera?
For HTC Desire, you need some special handling for taking pictures. Here is some code, you will have to adapt it to your needs :
protected static Uri createUriFromPhotoIntentForHtcDesireHD( Activity activity, Intent intent, Uri uri ) {
FileOutputStream fos = null;
try {
Bitmap bitmap = (Bitmap) intent.getExtras().get( "data" );
File outputDir = activity.getCacheDir();
File outputFile = File.createTempFile( "Photo-", ".jpg", outputDir );
fos = new FileOutputStream( outputFile );
bitmap.compress( Bitmap.CompressFormat.JPEG, 90, fos );
uri = Uri.fromFile( outputFile );
} catch ( IOException e ) {
Ln.e( e, "Error creating temp file for HTC Desire HD" );
} finally {
try {
if ( fos != null ) {
fos.close();
}
} catch ( IOException e ) {
Ln.e( e, "Error closing temp file for HTC Desire HD" );
}
}
return uri;
}
If you start an activity to take picture, then in you onActivityResult method, you would expect an intent to contain the uri of the file to download. If it doesn't, then use this code :
Uri uri = intent.getData();
// HTC Desire Bug
if ( uri == null && intent.getExtras() != null && intent.getExtras().get( "data" ) instanceof Bitmap ) {
uri = createUriFromPhotoIntentForHtcDesireHD( activity, intent, uri );
Ln.d( "The intent is %s", intent.getExtras().get( "data" ).getClass().getName() );
}
