BitmapFactory.decodeFile() returning null for existing image

I am facing an issue now. Why Bitmap.decodeFile() method is returning null? I tried with the following advice. but the above advice doesn’t help me.

sharing my codes here:

returning bitmap = null, help me to fix this issue.

private File createPhotoFile() throws IOException { String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date()); String imageFileName = "IMG_" + timeStamp + "_"; File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES); File image = File.createTempFile(imageFileName, ".png", storageDir); String mCurrentPhotoPath = image.toString();

    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath,bmOptions);

// bitmap = Bitmap.createScaledBitmap(bitmap,parent.getWidth(),parent.getHeight(),true); Bitmap markedImage = waterMark(bitmap, "your_string", Color.RED, 90, 90, true);

    File file = new File("path");
    OutputStream os = new BufferedOutputStream(new FileOutputStream(String.valueOf(markedImage)));
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, os);
    os.close();
    return file;
}
