Android: Throw OutOfMemory Exception during getting bitmap from file object

Question

I am trying to load bitmap image from file in some devices my code is working perfectly but on the other device it gives OutOfMemory exception.

String filePath  = mediaCursor.getString(mediaCursor.getColumnIndex(MediaStore.Images.Thumbnails.DATA));

fileName.add(filePath);

File file = new File(filePath);
Bitmap myBitmap = BitmapFactory.decodeFile(file.getAbsolutePath());
bitmapArray.add(myBitmap);

You can find out the size of the bitmap:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(file.getAbsolutePath(), options);
int imageHeight = options.outHeight;
int imageWidth = options.outWidth;

and then compress it to the desired size by setting sampleSize:

options = new BitmapFactory.Options();
options.inSampleSize = desired_scale_value;
Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath(), options);

And don`t forget to load bitmaps in non ui thread.
