Save over layed image to sdcard

I want to save the frame layout in which I have set a background and another image is placed on its top.
When I use onclick button it gives me 'force close error'.

I am using the following code:

 FrameLayout mainLayout = (FrameLayout) findViewById(R.id.imageView);
 File root = Environment.getExternalStorageDirectory();
 File file = new File(root,"androidlife.jpg");
 Bitmap b = Bitmap.createBitmap(mainLayout.getWidth(), mainLayout.getHeight(), Bitmap.Config.ARGB_8888);
 Canvas c = new Canvas(b);
 mainLayout.draw(c);
 FileOutputStream fos = null;
 try {
    fos = new FileOutputStream(file);

    if (fos != null) {
       b.compress(Bitmap.CompressFormat.JPEG, 90, fos);
       fos.close();
    }
 } catch (Exception e) {
    e.printStackTrace();
 }

Here is the error-log:

Problem is that you are doing this:

FrameLayout mainLayout = (FrameLayout) findViewById(R.id.imageView);

And R.id.imageView is most likely a reference to a ImageView. You better do something like:

ImageView mainLayout = (ImageView) findViewById(R.id.imageView);
