Java android android.view.WindowManager $ BadTokenException：無法添加窗口

我的應用程序崩潰，在日誌中我看到這個，我試圖找到我如何解決它，但只有我發現這是導致一個情感和一個人使用YourActivityName.this並能正常工作，但我喜歡這個，我的應用是崩潰

這是日誌：

Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token [email protected] is not valid; is your activity running?

     at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:620)

這是代碼：

protected void runServices() { 
     if (LocationUtil.isLocationEnabled(getBaseContext())) { 
      if (checkPermission()) { 
       runLocationService(); 
      } 
     } else { 
      AlertDialog.Builder dialog = new AlertDialog.Builder(this); 
      dialog.setMessage(getResources().getString(R.string.location_settings_disabled)); 
      dialog.setPositiveButton(getString(R.string.go_to_location_settings), new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface paramDialogInterface, int paramInt) { 
        App.getBus().post(new PageNavigateEvent(Const.APP_SETTINGS_LOCATION)); 
       } 
      }); 
      dialog.setNegativeButton(getResources().getString(R.string.cancel), new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface paramDialogInterface, int paramInt) { 
        finish(); 
       } 
      }); 
      dialog.show(); 
     } 
     runTrackerService(); 
     runConfigService(); 
    }

這行CAU的故障E：

dialog.show();

添加當前ActivityName.this，而不是this。

AlertDialog.Builder dialog = new AlertDialog.Builder(YourCurrentActivityName.this);
