In my App using custom PopupWindow where am using
popup.setBackgroundDrawable(new BitmapDrawable());
method. Now it is deprecated here and without this method i can't be able to give background for my popup. I read from article that its alternative is
popup.setsetBackgroundDrawable(new BitmapDrawable(Context.Resources,Drawable);
but here i am not using any drawable for my popUp. My code is given below where i am making my custom Popupwindow,here to fix this problem.
@Override
    public void onWindowFocusChanged(boolean hasFocus) {
        int[] location = new int[2];
        Button button = (Button) findViewById(R.id.VBG_img_pin_x);
        // Get the x, y location and store it in the location[] array
        // location[0] = x, location[1] = y.
        button.getLocationOnScreen(location);
        // Initialize the Point with x, and y positions
        p = new Point();
        p.x = location[0];
        p.y = location[1];
    }
    // The method that displays the popup.
    private void showPopup(final Activity context, Point p) {
//      Display display = getWindowManager().getDefaultDisplay();
        DisplayMetrics display = this.getResources().getDisplayMetrics();
        int width = display.widthPixels;
        int height = display.heightPixels;
//      int width = display.getWidth(); // deprecated
//      int height = display.getHeight(); // deprecated
        int popupWidth = width / 2;
        int popupHeight = height;
        ChatUtils.getScreenHeight(getBaseContext());
        // Inflate the popup_layout.xml
        LinearLayout viewGroup = (LinearLayout) context
                .findViewById(R.id.popup);
        LayoutInflater layoutInflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = layoutInflater.inflate(R.layout.popup_layout, viewGroup);
        onSetAlpha(240, layout);
//      layout.setAlpha((float) 0.95);
        // Creating the PopupWindow
        final PopupWindow popup = new PopupWindow(context);
        popup.setTouchable(true);
        popup.setFocusable(false);
        popup.setOutsideTouchable(true);
        popup.setContentView(layout);
        popup.setWidth(popupWidth);
        popup.setHeight(popupHeight);
        popup.setFocusable(true);
        // Some offset to align the popup a bit to the right, and a bit down,
        // relative to button's position.
        // Clear the default translucent background
        popup.setBackgroundDrawable(new BitmapDrawable());
}
