ProgressDialog로 인해 Android에서 충돌이 발생합니다.

Question

Android에서 간단한 CRUD 애플리케이션을 만들려고합니다.

로그인 할 때마다 응용 프로그램이 충돌하지만 내부적으로 로그인합니다. 로그 아웃하면 동일한 문제가 발생합니다. progressDialog.dismiss()에 오류가 발생합니다. 여기

은 AsyncTask를 클래스의 코드입니다 :

@Override 
protected void onPreExecute(){ 
    super.onPreExecute(); 
    path = ctx.getString(R.string.url); 
    progressDialog = new ProgressDialog(ctx); 
    progressDialog.setTitle("Signing In"); 
    progressDialog.setMessage("Validating your credentials!"); 
    //progressDialog.setCancelable(false); 
    progressDialog.show(); 
} 

그리고 여기 onPostExecute 방법에 내 코드입니다 :

@Override 
protected void onPostExecute(String result){ 
    super.onPostExecute(result); 
    if(progressDialog!=null){ 
     if(progressDialog.isShowing()){ 
      progressDialog.dismiss(); 
     } 
     progressDialog = null; 
    } 
    //some more code 
} 

내가 progressDialog.show() 라인과 IllegalArgumentException 오류에에서 창 누출 오류를 받고 있어요 progressDialog.dismiss() 행.

여기 내 활동 로그입니다 :

그것은 당신이 대화를 해제하기 전에 파괴하여해서 ProgressDialog를 표시하고있는 활동/조각처럼 보이는
