Android 1.6: “android.view.WindowManager$BadTokenException: Unable to add window — token null is not for an application”

Question

I\'m trying to open a dialog window, but every time I try to open it it throws this exception:

Uncaught handler: thread main exiting due to uncaught exceptio         


        

Answer 1

Just change it into

AlertDialog.Builder alert_Categoryitem = 
    new AlertDialog.Builder(YourActivity.this);

Instead of

AlertDialog.Builder alert_Categoryitem = 
    new AlertDialog.Builder(getApplicationContext());
