android - How to crop images from camera

Question

How can I crop the camera images. Now it is showing the the image for crop and after selecting the crop section while tap on the "Save" button. Its showing as "saving image". After that nothing is happen. Here is my code.

Button click :

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 0);
intent.putExtra("aspectY", 0);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 150);
intent.putExtra("return-data", true);
startActivityForResult(intent, CAMERA_PIC_REQUEST);

onActivityResult :

Bundle extras = data.getExtras();
Bitmap bitmap = (Bitmap) extras.get("data");
if (bitmap != null) {
    Img_View.setImageBitmap(bitmap);
}

You can use this code to perform cropping:

.....
final int CAMERA_CAPTURE = 1;
final int CROP_PIC = 2;
private Uri picUri;
....
@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button captureBtn = (Button) findViewById(R.id.capture_btn);
        captureBtn.setOnClickListener(this);
    }

    public void onClick(View v) {
        if (v.getId() == R.id.capture_btn) {
            try {
                // use standard intent to capture an image
                Intent captureIntent = new Intent(
                        MediaStore.ACTION_IMAGE_CAPTURE);
                // we will handle the returned data in onActivityResult
                startActivityForResult(captureIntent, CAMERA_CAPTURE);
            } catch (ActivityNotFoundException anfe) {
                Toast toast = Toast.makeText(this, "This device doesn't support the crop action!",
                        Toast.LENGTH_SHORT);
                toast.show();
            }
        }
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == CAMERA_CAPTURE) {
                // get the Uri for the captured image
                picUri = data.getData();
                performCrop();
            }
            // user is returning from cropping the image
            else if (requestCode == CROP_PIC) {
                // get the returned data
                Bundle extras = data.getExtras();
                // get the cropped bitmap
                Bitmap thePic = extras.getParcelable("data");
                ImageView picView = (ImageView) findViewById(R.id.picture);
                picView.setImageBitmap(thePic);
            }
        }
    }

    /**
     * this function does the crop operation.
     */
    private void performCrop() {
        // take care of exceptions
        try {
            // call the standard crop action intent (the user device may not
            // support it)
            Intent cropIntent = new Intent("com.android.camera.action.CROP");
            // indicate image type and Uri
            cropIntent.setDataAndType(picUri, "image/*");
            // set crop properties
            cropIntent.putExtra("crop", "true");
            // indicate aspect of desired crop
            cropIntent.putExtra("aspectX", 2);
            cropIntent.putExtra("aspectY", 1);
            // indicate output X and Y
            cropIntent.putExtra("outputX", 256);
            cropIntent.putExtra("outputY", 256);
            // retrieve data on return
            cropIntent.putExtra("return-data", true);
            // start the activity - we handle returning in onActivityResult
            startActivityForResult(cropIntent, CROP_PIC);
        }
        // respond to users whose devices do not support the crop action
        catch (ActivityNotFoundException anfe) {
            Toast toast = Toast
                    .makeText(this, "This device doesn't support the crop action!", Toast.LENGTH_SHORT);
            toast.show();
        }
    }
