Follow the link https://code.google.com/p/android-screenshot-library/downloads/list it allows you entire screenshot of any screen not only your app

adb shell /system/bin/screencap -p /sdcard/img.png this is a shell command take screenshot simple and fast

Try this

Process sh = Runtime.getRuntime().exec("su", null,null);
   OutputStream  os = sh.getOutputStream();
   os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));
            os.flush();
            os.close();

Use following code

Bitmap bitmap;
View v1 = MyView.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

Here MyView is the View through which we need include in screen.
