Android 12 - CAMERA2 - Pictures are corrupted when saving

I found an anomaly during tests with this particular device, the details are below:
Hardware: samsung,SM-A326B (Smartphone Samsung A32)
OS: Android 12
ONE UI: 4.1
Google Play: 01/may/22
Patch level: 01/june/22
These are the specs of one device that works properly, the only differences that I see are related to different version of the patch level.
Hardware: samsung,SM-A515F (Smartphone Samsung A51)
OS: Android 12
ONE UI: 4.1
Google Play: 01/may/22
Patch level: 01/may/22
I have implemented a customization of camera2 in my application, this always works except with this device, the specific anomaly is that the images are saved completely white and are corrupted, the image can only be recovered by third party software.
These are the permissions I ask for in the manifest:
<uses-feature android:name="android.hardware.location.gps " />
<uses-feature android:name="android.hardware.location.network" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" tools:ignore="ScopedStorage" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS" />
This is the code that I use to save the images
public void saveCameraImage(Image mImage, File mFile, String mOrientation, Context context) {
ByteBuffer buffer = mImage.getPlanes()[0].getBuffer();
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
FileOutputStream fileOutputStream = null;
try {
fileOutputStream = new FileOutputStream(mFile);
fileOutputStream.write(bytes);
} catch (IOException e) {
wil.WriteFile("saveImage - Exception: " + e.getMessage(), context);
} finally {
mImage.close();
if (null != fileOutputStream) {
try {
fileOutputStream.close();
} catch (IOException e) {
wil.WriteFile("saveImage - Exception: " + e.getMessage(), context);
} finally {
saveExifData(mFile.getPath(), context);
createThumbs(mOrientation, mFile, context);
}
}
}
}
This is the function that I named "saveExifData"
private void saveExifData(String filepath, Context context) {
try {
if (filepath.endsWith(IMAGE_FORMAT)) {
File file = new File(filepath);
if (file.exists()) {
DbGest dbGest = DbGest.getInstance(context);
String dateTime = dbGest.getTimestampFromFileToSend(filepath, "dateTime", context);
String dateTimeGps = dbGest.getTimestampFromFileToSend(filepath, "gps", context);
String dateTimeDesc = dbGest.getTimestampFromFileToSend(filepath, "dateTimeDesc", context);
ExifInterface exifInterface = new ExifInterface(filepath);
exifInterface.setAttribute(ExifInterface.TAG_COPYRIGHT, "xxxxx ");
exifInterface.setAttribute(ExifInterface.TAG_MODEL, Build.MANUFACTURER + "," + Build.MODEL);
exifInterface.setAttribute(ExifInterface.TAG_SOFTWARE, dbGest.getSetting("appName", context));
exifInterface.setAttribute(ExifInterface.TAG_DATETIME, dateTime);
exifInterface.setAttribute(ExifInterface.TAG_DATETIME_ORIGINAL, dateTime);
exifInterface.setAttribute(ExifInterface.TAG_USER_COMMENT, "Immagine scattata tramite " + dbGest.getSetting("appName", context) + " il " + dateTimeDesc);
CoordinatesData position = DbGest.getInstance(context).getBetterPositionKnown(context);
exifInterface.setAttribute(ExifInterface.TAG_GPS_LATITUDE, String.valueOf(position.getLat()));
exifInterface.setAttribute(ExifInterface.TAG_GPS_LONGITUDE, String.valueOf(position.getLng()));
exifInterface.setAttribute(ExifInterface.TAG_GPS_DATESTAMP, dateTimeGps);
exifInterface.setAttribute(ExifInterface.TAG_GPS_SPEED, String.valueOf(position.getSpeed()));
exifInterface.setLatLong(position.getLat(), position.getLng());
exifInterface.saveAttributes();
}
}
} catch (Exception e) {
wil.WriteFile("saveExifData - Exception: " + e.getMessage(), context);
}
}
So I guess it's not a permission issue, also there are no exceptions, so I don't know how to fix this

After several test and debugging I find the cause of the bug.
The problem it is in the "saveExifData", for some reason this row of code
exifInterface.setAttribute(ExifInterface.TAG_COPYRIGHT, "xxxx");
it is the cause of the problem

Getting null pointer exception when trying to get the URI for a file

When the activity opens, a dialog window opens asking the user to either take a picture from the camera, or choose one from the gallery. As soon as I hit the button to open the camera, the app crashes and I get a Null Pointer exception related to getting the URI. I have been following Google's walkthrough for saving pictures form the camera and can't seem to find where the issue is.
Line where the error occurs:
Uri photoURI = FileProvider.getUriForFile(CreatePostActivity.this,
"xyz.beerme.beerme.provider",
photoFile);
Whole method:
cameraButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if(intent.resolveActivity(getPackageManager()) != null){
File photoFile = null;
try{
photoFile = createImageFile();
} catch (IOException ex){
Snackbar message = Snackbar.make(findViewById(R.id.activity_create_post), "Error creating image", Snackbar.LENGTH_LONG);
message.show();
}
if(photoFile != null){
Uri photoURI = FileProvider.getUriForFile(CreatePostActivity.this,
"xyz.beerme.beerme.provider",
photoFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(intent, REQUEST_CAMERA);
}
}
dialog.dismiss();
}
});
createImageFile method:
private File createImageFile() throws IOException{
String timeStamp = new SimpleDateFormat("yyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_beerme";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName,
".jpg",
storageDir
);
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}

</paths>

Try Below code for createImageFile method
private File createImageFile() {
File storageDir = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
// path = path + (timeStamp + "1jpg");
try {
file = File.createTempFile(timeStamp, ".jpg", storageDir);
} catch (IOException e) {
e.printStackTrace();
}
if (Build.VERSION.SDK_INT >= 24)
mCurrentPhotoPath = String.valueOf(FileProvider.getUriForFile(MainActivity.this,
BuildConfig.APPLICATION_ID + ".provider", file));
else
mCurrentPhotoPath = String.valueOf(Uri.fromFile(file));
return file;
}

In case anyone finds this in the future, I typed "provider" instead of "fileprovider". As provider does not exist, that is the source of the exception.

Android FileNotFoundException in uploading Photo

I have problem with finding photo after saving.
Here is how i am creating Intent to take photo from camera and save filePath to it.
private void takePhoto(int position)
{
Meter meter = adapter.getItem(position);
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File tempFile = createTempFile(meter.id, JPEG_FILE_SUFFIX, storageDir);
if(tempFile != null)
{
lastPhotoPath = tempFile.getAbsolutePath();
Log.d(TAG, "temp picture path=" + lastPhotoPath);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(tempFile));
try
{
startActivityForResult(takePictureIntent, TAKE_PHOTO_REQUEST);
lastPhotoPosition = position;
}
catch(ActivityNotFoundException exc)
{
Log.e(TAG, "activity to take photo not found");
}
}
}
Then later i want to upload this image to server.
Here is how i am doing this.
public void compose(OutputStream out) throws DataStorageException
{
Log.d("MainMenuActivity", "file not found in path " + path);
InputStream in = null;
try
{
in = new BufferedInputStream(new FileInputStream(path));
// TODO: there is a better way
byte[] buf = new byte[8192];
while(true)
{
int length = in.read(buf);
if(length < 0)
break;
out.write(buf, 0, length);
}
}
catch(FileNotFoundException exc)
{
throw new DataStorageInternalErrorException("FileNotFoundException, FileRequestComposer compose");
}
catch(IOException exc)
{
// TODO: probably network error
throw new DataStorageInternalErrorException("IOException, FileRequestComposer compose");
}
finally
{
if(in != null)
{
try
{
in.close();
}
catch(IOException exc)
{
// FIXME
}
}
}
}
I check filePath from saving and filePath to save they both completely identical:
temp picture path=/mnt/sdcard/Pictures/19520983731349.jpg
file not found in path /mnt/sdcard/Pictures/19520983731349.jpg
And the exception is thrown in method compose()
FileNotFoundException, FileRequestComposer compose
Any ideas where i am doing wrong?
P.S. And i can't see this file in /mnt/sdcard/Pictures mb. he is lost or somethinf like this? Please suggest any ideas.
P.P.S Manifest

The problem is likely with the way you create File. Instead of createTempFile try regular constructor :
File tempFile = new File(storageDir, meter.id + JPEG_FILE_SUFFIX);
Generally, you also want to make sure that your storageDir folder exists and create it with mkdirs if needed.

Add this path for storing image on sdcard.
final String uploadFilePath = "/mnt/sdcard/";

Take a picture from camera

i have a problem with code of take a picture and save. It crash when i launchCamera().
Can you help me please?
private void launchCamera() {
try {
mOutputFile = File.createTempFile("prova", null);
Intent intentCamera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intentCamera.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(mOutputFile));
startActivityForResult(intentCamera, CAMERA_REQUEST);
} catch (Exception e) {
Toast t = Toast.makeText(this, "ERROR:\n" + e.toString(), Toast.LENGTH_LONG);
t.show();
}
}

I am using this piece of code try it out :
/**
* This method is used to start the camera activity and save the image taken as the imagename passed
*
* #param imagename : this is the name of the image which will be saved
*/
private void clickPicture(String imagename) {
Intent getCameraImage = new Intent("android.media.action.IMAGE_CAPTURE");
File cameraFolder;
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
cameraFolder = new File(android.os.Environment.getExternalStorageDirectory(),"myfolder/");
else
cameraFolder= context.getCacheDir();
if(!cameraFolder.exists())
cameraFolder.mkdirs();
String imageFileName = imagename;
File photo = new File(Environment.getExternalStorageDirectory(), "myfolder/" + imageFileName);
getCameraImage.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
Uri.fromFile(photo);
startActivityForResult(getCameraImage, 1);
}
and add the permisson in your manifest file :
<uses-permission android:name="android.permission.CAMERA" ></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Maybe you didn't added the necessary permissions in the manifest file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
Also I would suggest you to go over this blog post I wrote on this topic of taking a picture using the build-in Camera Activity:
Take Picture with build in Camera Activity

To access the device camera, you must declare the CAMERA permission in your Android Manifest
