Hi people I am using a FlexiCrop andtrying to crop image in irregular shape my code for activity is looks like this
public class CropActivity
extends Activity implements OnTouchListener {
private Uri mImageCaptureUri;
private ImageView drawImageView;
private Bitmap sourceBitmap;
private Path clipPath;
private static final int PICK_FROM_FILE = 1;
private static final int CAMERA_CAPTURE = 2;

float upy = 0;

public void onClick( DialogInterface dialog, int item ) { //pick from camera
if (item == 0) {
try {
//use standard intent to capture an image

//we will handle the returned data in onActivityResult
startActivityForResult(captureIntent, CAMERA_CAPTURE);
} catch(ActivityNotFoundException e){
e.printStackTrace();

}
} else { //pick from file
