Activity To Crop The Selected Image:

public class ImageSelecter extends Activity{

    }

            // retrieve data on return
            cropIntent.putExtra("return-data", true);
            // start the activity - we handle returning in onActivityResult
            startActivityForResult(cropIntent, RESULT_CROP);
        }
        // respond to users whose devices do not support the crop action
        catch (ActivityNotFoundException anfe) {
            // display an error message
            String errorMessage = "your device doesn't support the crop action!";
            Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
            toast.show();
        }
    }
