}

Method OnActivityResult:

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

// if the result is capturing Image

if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) {

if (resultCode == RESULT_OK) {

previewCapturedImage();

} else if (resultCode == RESULT_CANCELED) {

Toast.makeText(getApplicationContext(),

“User cancelled image capture”, Toast.LENGTH_SHORT)

.show();
