View not attached to window manager, dialog dismiss

Question

So I\'ve activity called GameActivity.java and in this activity I call DialogAnswer.show() which simple shows some picture on screen.

Answer 1

using try catch may not be a efficient way to solve this problem as may cause memory leak; for this question, as the context is used as param, so before using the code dialog.dismiss, we can use codes below to protect:

public void onFinish() {
   if{ctx instanceof Activity && !((Activity)ctx.isfinishing()){
           dialog.dismiss(); //this is line 36
   }
}

also, another method can be used to patch this crash in the function of onDestroy() in the activity, add the code:

protected void onDestroy() {
  if(dialog != null){
     dialog.dismiss();
     dialog = null;
  }
}
