Activity has leaked window that was originally added

Question

What is this error, and why does it happen?

05-17 18:24:57.069: ERROR/WindowManager(18850): Activity com.mypkg.myP has leaked window com.android.internal.pol         


        

Answer 1

Window leaked exceptions have two reasons:

1) showing the dialog when Activity Context doesn't exists, to solve this you should show the dialog only you are sure Activity exists:

if(getActivity()!= null && !getActivity().isFinishing()){
        Dialog.show();
}

2) not dismiss the dialog appropriately, to solve use this code:

@Override
public void onDestroy(){
    super.onDestroy();
    if ( Dialog!=null && Dialog.isShowing() ){
        Dialog.dismiss();
}
}
