Save an Image with TextureView?

I hope you can fix my problem:
I have got a textureview to takes photos but when he capture photos, the file who need to contain the picture is empty. I don't know where and what is the problem. I just think that the problem is when the file is created. Thank you to help me.
This is a part of my code :
private void takePicture() throws CameraAccessException, IOException {
if(cameraDevice == null){
return;
}
CameraManager manager = (CameraManager) Objects.requireNonNull(getContext()).getSystemService(Context.CAMERA_SERVICE);
CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraDevice.getId());
Size[] jpegSizes = null;
jpegSizes = characteristics.get(CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP).getOutputSizes(ImageFormat.JPEG);
int width = 640;
int height = 480;
if(jpegSizes!=null && jpegSizes.length>0){
width = jpegSizes[0].getWidth();
height = jpegSizes[0].getHeight();
}
ImageReader reader = ImageReader.newInstance(width,height, ImageFormat.JPEG, 1);
List<Surface> outputSurface = new ArrayList<>(2);
outputSurface.add(reader.getSurface());
outputSurface.add(new Surface(textureView.getSurfaceTexture()));
final CaptureRequest.Builder captureBuilder = cameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE);
captureBuilder.addTarget(reader.getSurface());
captureBuilder.set(CaptureRequest.CONTROL_MODE,CameraMetadata.CONTROL_MODE_AUTO);
int rotation = Objects.requireNonNull(getActivity()).getWindowManager().getDefaultDisplay().getRotation();
captureBuilder.set(CaptureRequest.JPEG_ORIENTATION,ORIENTATIONS.get(rotation));
// First I get the path to gallery and crate new Album to my app
File file = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS);
mImageFolder = new File(file, "Fluico");
if (!mImageFolder.exists()) {
if (!mImageFolder.mkdirs()) {
Log.d("Fluicophoto", "failed to create directory");
}
}
/*Second I cut mFile = new File(getActivity().getExternalFilesDir(null), "pic.jpg");
from onActivityCreated and add here with the new path from my Album*/
#SuppressLint("SimpleDateFormat") String timestamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String prepend = "IMAGE_" + timestamp + "_";
file = File.createTempFile(prepend, ".jpg", mImageFolder);
Toast.makeText(getContext(), "file need to be save", Toast.LENGTH_SHORT).show();
ImageReader.OnImageAvailableListener readerListener = new ImageReader.OnImageAvailableListener() {
#Override
public void onImageAvailable(ImageReader reader) {
Image image = null;
image = reader.acquireLatestImage();
ByteBuffer buffer = image.getPlanes()[0].getBuffer();
byte[] bytes = new byte[buffer.capacity()];
buffer.get(bytes);
try {
save(bytes);
} finally {
image.close();
}
}
};
reader.setOnImageAvailableListener(readerListener,mBackgroundHandler);
final CameraCaptureSession.CaptureCallback captureListener = new CameraCaptureSession.CaptureCallback() {
#Override
public void onCaptureCompleted(CameraCaptureSession session, CaptureRequest request, TotalCaptureResult result) {
super.onCaptureCompleted(session, request, result);
Toast.makeText(getContext(), "saved", Toast.LENGTH_SHORT).show();
try{
createCameraPreview();
}catch (CameraAccessException e){
Toast.makeText(getContext(), "capture not comleted", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
};
cameraDevice.createCaptureSession(outputSurface, new CameraCaptureSession.StateCallback() {
#Override
public void onConfigured( CameraCaptureSession session) {
try {
session.capture(captureBuilder.build(), captureListener, mBackgroundHandler);
} catch (CameraAccessException e) {
e.printStackTrace();
Toast.makeText(getContext(), "capture not configured", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onConfigureFailed( CameraCaptureSession session) {
}
},mBackgroundHandler);
}
private void save(byte[] bytes) {
OutputStream outputStream = null;
try {
outputStream = new FileOutputStream(file);
outputStream.write(bytes);
outputStream.close();
Toast.makeText(getContext(), "it's good", Toast.LENGTH_SHORT).show();
}catch (IOException e){
Toast.makeText(getContext(), "file not found", Toast.LENGTH_SHORT).show();
}
}

Try with below code:
File myDir;
String fname;
String id = "123456";
int count = 0;
String root = Environment.getExternalStorageDirectory().toString();
myDir = new File(root + "/PhotoApp/" + id);
myDir.mkdirs();
count++;
counter.setText(String.valueOf(count));
fname = "" + id + "-" + count + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) file.delete();
This code will create a folder PhotoApp and inside the folder, all the images will store.
You can get full code with the camera in my GitHub:

How to share image with a button? [duplicate]

This question already has answers here:
How to use "Share image using" sharing Intent to share images in android?
(17 answers)
Closed 2 years ago.
I am making QR code generator
So far I made a generator button and save button.
It works fine.
I am trying to work on the sharing button.
It takes a few days to figure out as a beginner and still I cannot make it work.
At this code, if I click share, then the app closes.
/**Barcode share*/
findViewById(R.id.share_barcode).setOnClickListener(v -> {
Bitmap b = BitmapFactory.decodeResource(getResources(),R.id.qr_image);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(getContentResolver(), b, "Title", null);
Uri imageUri = Uri.parse(path);
share.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(share, "Select"));
});
I guessed the problem was path.
I use savepath to save qr code image. And then maybe it conflicts with String path
So I tried String savePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + "/Camera/";;
It's not working. So maybe it's different problem and I don't know how to fix it.
Could you show me how to fix?

I think you can solve this by:
Saving the bitmap in a file.
Then sharing the URI of that file in the intent.
In the code below, I am saving the image at the app level directory, you can choose your own and the code is written in kotlin.
Note: If you are using an app-level directory for saving the image then you must use the file provide to get the URI else it may result in FileUriExposedException
try {
val file = File(getExternalFilesDir(null),System.currentTimeMillis().toString() + ".png")
file.createNewFile()
val b = imageView.drawable.toBitmap()
FileOutputStream(file).use { out ->
b.compress(Bitmap.CompressFormat.PNG, 100, out)
}
val share = Intent(Intent.ACTION_SEND)
share.type = "image/jpeg"
val photoURI = FileProvider.getUriForFile(this, applicationContext.packageName.toString() + ".provider", file)
share.putExtra(Intent.EXTRA_STREAM, photoURI)
startActivity(Intent.createChooser(share, "Share Image"))
Toast.makeText(this, "Completed!!", Toast.LENGTH_SHORT).show()
} catch (e: IOException) {
e.printStackTrace()
Toast.makeText(this, e.message, Toast.LENGTH_SHORT).show()
}
In JAVA:
public void shareImage(Activity activity, ImageView imageView) {
try {
File file = new File(activity.getExternalFilesDir(null), System.currentTimeMillis() + ".png");
file.createNewFile();
Bitmap bitmap = drawableToBitmap(imageView.getDrawable());
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
Intent share = new Intent("android.intent.action.SEND");
share.setType("image/jpeg");
Uri photoURI = FileProvider.getUriForFile(activity,activity.getPackageName(), file);
share.putExtra("android.intent.extra.STREAM", photoURI);
activity.startActivity(Intent.createChooser(share, "Share Image"));
} catch (Exception var14) {
}
}
public static Bitmap drawableToBitmap (Drawable drawable) {
Bitmap bitmap;
if (drawable instanceof BitmapDrawable) {
BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
if(bitmapDrawable.getBitmap() != null) {
return bitmapDrawable.getBitmap();
}
}
if(drawable.getIntrinsicWidth() <= 0 || drawable.getIntrinsicHeight() <= 0) {

After follow the tutorial, I have changed my code to
try {
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmapOptions.inJustDecodeBounds = false;
bitmapOptions.inPreferredConfig = Bitmap.Config.RGB_565;
bitmapOptions.inDither = true;

BitmapFactory.Options opts = new BitmapFactory.Options();
Bitmap bm = BitmapFactory.decodeFile(f.getAbsolutePath(), opts);
ExifInterface exif = new ExifInterface(f.getAbsolutePath());
String orientString = exif.getAttribute(ExifInterface.TAG_ORIENTATION);
int orientation = orientString != null ? Integer.parseInt(orientString) : ExifInterface.ORIENTATION_NORMAL;
int rotationAngle = 0;
if (orientation == ExifInterface.ORIENTATION_ROTATE_90) rotationAngle = 90;
if (orientation == ExifInterface.ORIENTATION_ROTATE_180) rotationAngle = 180;
if (orientation == ExifInterface.ORIENTATION_ROTATE_270) rotationAngle = 270;
Matrix matrix = new Matrix();
matrix.setRotate(rotationAngle, (float) bm.getWidth() / 2, (float) bm.getHeight() / 2);
Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bitmapOptions.outWidth, bitmapOptions.outHeight, matrix, true);
Global.img = bitmap;
b.setImageBitmap(bitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
//p = path;
f.delete();
OutputStream outFile = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
setRotate in matrix.setRotate cannot be solved.
I get a red line underneath (bm, 0, 0, bitmapOptions.outWidth, bitmapOptions.outHeight, matrix, true); (cannot resolved method createBitmap )
*********Edit*********
After I import android.graphics.Matrix instead of android.opengl.Matrix, the app crashed.
LogCat error

This is line 236
Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bitmapOptions.outWidth, bitmapOptions.outHeight, matrix, true);

Change to this Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(),matrix, true);

I guess you imported the wrong Matrix class, you should import android.graphics.Matrix, not android.opengl.Matrix, please double check.

It's probably because of the decodeStream method.
Bitmap imageBitmap = BitmapFactory.decodeStream(is2, null, options);
You parsed null at the when it asks for a Rectangle and when you tried to create a scaled bitmap it was not valid.

i found my error Bitmap imageBitmap = BitmapFactory.decodeStream(is2, null, options); decoding twice
