Getting error while adding a webview in IntentService android

Question

I was refering this post for adding a webview in service. However, I keep getting the error that windowManager is being added, but it already has a parent.

Code:

 WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
    WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, PixelFormat.TRANSLUCENT);
    params.gravity = Gravity.TOP | Gravity.START;
    params.x = 0;
    params.y = 0;
    params.width = 0;
    params.height = 0;

    LinearLayout view = new LinearLayout(this);
    view.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));

    webView = new WebView(this);
    webView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));

    view.addView(webView);
    webView.loadUrl("http://google.com");
    windowManager.addView(webView, params);

Log:

can you share your layout xml and code. The error is you are to add web view which has already been added in other layout. — Praveen, Jan 09 '17 at 11:35
windowManager.addView(webView, params); >> here is the error. You should use windowManager.addView(view, params); according to your code — Praveen, Jan 09 '17 at 11:41

view.addView(webView) Just remove this line then it should work properly. If not create proper webview object using application context or creating xml file. Basically error is you are adding webview two times to the view.
