nullpointerexception - Android Camera OnActivityResult resets photo path to null

Question

I'm having a problem while testing my app on a friends Galaxy S4 (GT i9505, Android 5.1). When giving a file URI to camera intent, OnActivityResult gives result Activity.RESULT_OK and and the path is null. It is working on most of other devices I tested (LG G3, nexus 5...). This is my code:

GetOutputMediaFile

public File getOutputMediaFile(int type){
    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), MediaChooserConstants.folderName);
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            return null;
        }
    }

    // Create a media file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    File mediaFile;
    if (type == MediaChooserConstants.MEDIA_TYPE_IMAGE){
        mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg");
    } else if(type == MediaChooserConstants.MEDIA_TYPE_VIDEO) {
        mediaFile = new File(mediaStorageDir.getPath() + File.separator + "VID_" + timeStamp + ".mp4");
    } else {
        return null;
    }
    return mediaFile;
}

OnActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == Activity.RESULT_OK) {
        String picturePath = null;
        if (requestCode == MediaChooserConstants.CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
            picturePath = fileUri.getPath(); // <--- fileURI is null
        }
    }
}

DispatchTakePhotoIntent

private void dispatchTakePictureIntent() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    File file = Utils.getInstance().getOutputMediaFile(MediaChooserConstants.MEDIA_TYPE_IMAGE);

    fileUri = Uri.fromFile(file); // create a file to save the image
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name

    //fileUri is not null here while debugging (../DCIM/.../IMG_XXX.jpg)
    startActivityForResult(intent, MediaChooserConstants.CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

}

you need to save the file path to the bundle in onSaveInstanceState and then get it again in onRestoreInstanceState from the bundle
