Context Menu/Window in WebView inside PopupWindow crashes the app?

Question

I have an app with PopupWindow containing WebView that opens Facebook's page, any context menu like: the Autocomplete on text fields in the WebView or even the Long Press that should display options for the user to copy/paste/cut crashes the app right away with the follow error:

FATAL EXCEPTION: main
android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@418cdab0 is not valid; is your activity running?

Notice: my understanding of the problem is that the context menu/window are shown actually in the scope of the app itself not inside the WebView using another PopWindow (Auto generated by the Core WebView Class) this class references the context incorrectly.

My Code is as follows:

Main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/openpopup"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Open Popup Window" />

</LinearLayout>

Popup.xml

As commented above in my answer you can use Custom dialog for your requirement.. i have created a sample PopupDialog.. please check and let me know..if it solve your purpose.. Autocomplete and ContextMenus will work as expected..

MyActivity.java

package com.example.testapp;

import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;

public class MyActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final Button btnOpenPopup = (Button) findViewById(R.id.openpopup);
    btnOpenPopup.setOnClickListener(new Button.OnClickListener() {

        @SuppressLint("NewApi")
        @Override
        public void onClick(View arg0) {

            final PopupDialog popupDialog = new PopupDialog(MyActivity.this);
            popupDialog.setContentView(R.layout.popup);

            WebView popupWebview = (WebView) popupDialog.findViewById(R.id.webviewActionView);
            popupWebview.setWebChromeClient(new WebChromeClient());
            popupWebview.setWebViewClient(new WebViewClient());

            popupWebview.loadUrl("http://m.facebook.com");
            Button btnDismiss = (Button) popupDialog
                    .findViewById(R.id.dismiss);
            btnDismiss.setOnClickListener(new Button.OnClickListener() {
                @Override
                public void onClick(View v) {

                    // TODO Auto-generated method stub
                    popupDialog.dismiss();
                }
            });
//                popupDialog.showAtLocation(50,50);
            popupDialog.showAsDropDown(findViewById(R.id.openpopup));
        }
    });
}
}

PopupDialog.java

package com.example.testapp;

import android.app.Dialog;
import android.content.Context;
import android.view.Gravity;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;

public class PopupDialog extends Dialog{
private final Context mContext;

public PopupDialog(Context context) {
    super(context);
    mContext=context;
    requestWindowFeature(Window.FEATURE_NO_TITLE);
}

public void showAtLocation(int x,int y)
{
    WindowManager.LayoutParams wmlp = getWindow().getAttributes();
    wmlp.gravity = Gravity.TOP | Gravity.LEFT;
    wmlp.x = x;
    wmlp.y = y;
    show();
}
public void showAsDropDown(View view)
{
    float density = mContext.getResources().getDisplayMetrics().density;
    WindowManager.LayoutParams wmlp = getWindow().getAttributes();
    int[] location = new int[2];
    view.getLocationInWindow(location);
    wmlp.gravity = Gravity.TOP | Gravity.LEFT;
    wmlp.x = location[0]+(int)(view.getWidth()/density);
    wmlp.y = location[1]+(int)(view.getHeight()/density);
    show();
}
}

edit: added popup.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:minHeight="400dp"
          android:minWidth="200dp"
          android:background="@android:color/background_light"
          android:orientation="vertical" >

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_margin="1dp"
        android:background="@android:color/darker_gray"
        android:orientation="vertical" >
    >

    <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_margin="20dp"
            android:orientation="vertical" >

        <WebView
            xmlns:ptr="http://schemas.android.com/apk/res-auto"
                android:id="@+id/webviewActionView"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:minHeight="200dp"
                android:minWidth="200dp"
                android:scrollbars="none" >
        </WebView>

        <Button
                android:id="@+id/dismiss"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:text="Dismiss" />
    </LinearLayout>
</LinearLayout>

Answer 2

yes i think you should use your activity name in place of "getBaseContext()". i am just created one demo with your code. its working fine in my pc. and when you are getting this exception?
