Android Java Class to take a snapshot of a View on screen and save as Image

ViewToImage.java

/*
This class converts any Layout or View to image and saves in Phone.
In one of my projects, I had a requirement of saving whatever is being displayed on the Screen as an image. 
I created a class for it so that in future it becomes easy to reuse.


Usage Example
-----------------------------------------------------------------------------------------------------------
FrameLayout mLin_FramePreview1 = (FrameLayout)findViewById(R.id.lin_FramePreview1);
ViewToImage v = new ViewToImage(mLin_FramePreview1);

*/

 public class ViewToImage {

    // This Class is tested by passing a FrameLayout, LinearLayout, RelativeLayout here    

    /*
    This  Constructor accepts a View as a parameter.
    You can pass the top level parent View to capture the whole screen.
    To know how to use it, see 'Usage Example' above.
    */
    public ViewToImage(View view) {

        Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        view.draw(canvas);

        try {
            // I'm storing the output image in this path. Change the path and image name if you want
            FileOutputStream output = new FileOutputStream(Environment.getExternalStorageDirectory() + "/savedImage.png");
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
            output.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
