Take a screenshot - Background Service

I'm trying to take a screenshot using a background service. This service is like a Facebook chathead, but I want it to take an screenshot when I do a click.

Preview Picture

I've developed some code but it doesn't work. The last I've tried was:

private void takeScreenshot() {
    Date now = new Date();
    android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

        // image naming and path  to include sd card  appending name you choose for file
        String mPath = Environment.getExternalStorageDirectory().toString() + "/capture/" + now + ".jpg";

        // create bitmap screen capture
        Bitmap bitmap;
        View v1 = chatHead.getRootView();
        v1.setDrawingCacheEnabled(true);
        bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);

        OutputStream fout = null;
        File imageFile = new File(mPath);

        try {
            fout = new FileOutputStream(imageFile);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fout);
            fout.flush();
            fout.close();

        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
}

But is taking an screenshot to my button not to the screen.

I know the problem is here:

View v1 = chatHead.getRootView();

But I don't know how to fix it. Can anyone help me?

I'm actually using Android Studio 2.2.2 and Android 4.0 or greater.
