Try like this if you need to get rounded image ..

Your MainActivity.java class

public class MainActivity extends Activity {
    private static final int REQUEST_CODE = 1;
    private Bitmap bitmap;
    private ImageView imageView;
    Bitmap roundedBitmapImage;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        imageView = (ImageView) findViewById(R.id.result);

    }

    public void pickImage(View View) {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        startActivityForResult(intent, REQUEST_CODE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK)


            try {
                // We need to recycle unused bitmaps
                if (bitmap != null) {
                    bitmap.recycle();
                }
                InputStream stream = getContentResolver().openInputStream(
                        data.getData());
                bitmap = BitmapFactory.decodeStream(stream);
                stream.close();

               /* Bitmap bitmap1=BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
                Bitmap bitmap2=BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);

                Bitmap resultingImage=Bitmap.createBitmap(320, 480, bitmap1.getConfig());

                Canvas canvas = new Canvas(resultingImage);

                Paint paint = new Paint();
                paint.setAntiAlias(true);
                Path path=new Path();
                path.lineTo(150, 0);
                path.lineTo(230, 120);
                path.lineTo(70, 120);
                path.lineTo(150, 0);

                canvas.drawPath(path, paint);

                paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
                canvas.drawBitmap(bitmap2, 0, 0, paint);*/

               //-------> compositeImageView.setImageBitmap(resultingImage);

                // Use this when to provide any shape to image i.e Fit image to any shape.
                // under mentioned taking reference from Rounder class. Finally changing image in round shape.
                // Here we are passing reference  bitmap.
                roundedBitmapImage = new  Rounder().getRoundedShape(bitmap);

                imageView.setImageBitmap(roundedBitmapImage);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        super.onActivityResult(requestCode, resultCode, data);
    }
}

And your rounder class ..

/** This class crops image to round shape */

public class Rounder {
    public Bitmap getRoundedShape(Bitmap scaleBitmapImage) {
        int targetWidth = 125;
        int targetHeight = 125;
        Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight,
                Bitmap.Config.ARGB_8888);

        Canvas canvas = new Canvas(targetBitmap);

        Path path = new Path();

        path.addCircle(((float) targetWidth - 1) / 2,
                ((float) targetHeight - 1) / 2,
                (Math.min(((float) targetWidth), ((float) targetHeight)) / 2),
                Path.Direction.CCW);

        canvas.clipPath(path);

        Bitmap sourceBitmap = scaleBitmapImage;

        canvas.drawBitmap(sourceBitmap, new Rect(0, 0, sourceBitmap.getWidth(),
                sourceBitmap.getHeight()), new Rect(0, 0, targetWidth,
                targetHeight), null);

        return targetBitmap;
    }
}
