Exception while Loading Image from gallery

I am developing a Finger painting application. I have following code for loading an image from gallery (to paint over it). The code is working fine in my smartphone (android 4.2.2 - API 17). but when i run it on lower versions (2.3.3 etc), It just shows a run time error and app is closed.

   protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);


    if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK)
        try {
            // We need to recyle unused bitmaps
            if (bitmap != null) {
                bitmap.recycle();
            }
            InputStream stream = getContentResolver().openInputStream(
                    data.getData());
            myBitmap = BitmapFactory.decodeStream(stream);
            stream.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

and for calling this

Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    startActivityForResult(intent, REQUEST_CODE);

In my understanding, this code should work for all the APIs. But there is some problem with lower versions. please help me out

EDIT:

(I have deleted DISPLAY code, that was causing problem. still the problem persists. here is new logcat. LOGCAT after clicking LOAD button

Solution

the logs says this:

java.lang.NoSuchMethodError: android.view.Display.getSize

so, this is the problematic line:

display.getSize(size);

it's supported only from API 13.

instead , you can use getResources().getDisplayMetrics().

in order to avoid having such bugs, you should use Lint (the button that looks like a checkbox with a "V" in it).
