android-从图库/相机拍照的ANR

Question

Did someone face the issue when ANR happened after choosing picture from gallery or taking a photo from camera (in my case it returns byte[] array to my app)?

How to solve it?

Upd. Here's the code how an image is picked. But this part of code didn't change and some time ago it worked (some other parts of code were changed, I don't know if it's important).

void chooseOrTakePhotoDialog(OnActivityResultListener listener) {
    onActivityResultListener = listener;
    final CharSequence[] items = { "Take Photo", "Choose from Library", "Cancel" };
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Add Photo");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {
            if (items[item].equals("Take Photo")) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, REQUEST_CAMERA);
            } else if (items[item].equals("Choose from Library")) {
                Intent intent = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                intent.setType("image/*");
                startActivityForResult(
                        Intent.createChooser(intent, "Select File"),
                        SELECT_FILE);
            } else if (items[item].equals("Cancel")) {
                dialog.dismiss();
            }
        }
    });
    builder.show();
}

interface OnActivityResultListener {
    void onPhotoByteArray(byte[] bytes);
}
private OnActivityResultListener onActivityResultListener;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.wtf("onActivityResult", "req="+requestCode+" res="+resultCode+" data="+data);
    if (resultCode != RESULT_OK) return;
    switch (requestCode) {
        case REQUEST_CAMERA:
            if (onActivityResultListener != null) {
                Bitmap bmp = (Bitmap) data.getExtras().get("data");
                ByteArrayOutputStream stream = new ByteArrayOutputStream();
                bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
                onActivityResultListener.onPhotoByteArray(stream.toByteArray());
            }
            break;
        case SELECT_FILE:
            Uri uri = data.getData();
            try {
                byte[] bytes = Helper.readBytes(getContentResolver().openInputStream(uri));
                onActivityResultListener.onPhotoByteArray(bytes);
            } catch (IOException e) {
                e.printStackTrace();
            }
            break;
    }
}

For the case of SELECT_FILE , you can try getting Bitmap like below.

 case SELECT_FILE:
            if (data != null) {
                try {
                    Uri selectedImage = data.getData();
                    String[] filePath = {MediaStore.Images.Media.DATA};
                    Cursor c = getApplicationContext().getContentResolver().query(
                            selectedImage, filePath, null, null, null);
                    c.moveToFirst();
                    int columnIndex = c.getColumnIndex(filePath[0]);
                    String picturePath = c.getString(columnIndex);
                    c.close();
                    Bitmap thumbnail = BitmapFactory.decodeFile(picturePath); 

                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                break;
