我想通过在android工作室，类名obs_bgw，我的代码工作正常，但1分钟后运行应用程序自动刷新应用程序不工作，我检查在Firebase崩溃错误是致命的异常ProgressDialog android studio

问题是进度对话框，行51 final ProgressDialog dialog = ProgressDialog.show(this,null, "Please Wait");当他刷新日期停止工作

您泄漏处理程序...它仍然活跃，即使活动是密切，你必须之前取消Handler的工作离开活动 – Selvin

所以我不得不删除代码的刷新，导致他的内容处理程序的 –

不，你必须谷歌“取消处理程序的工作” – Selvin

异常android.view.WindowManager $ BadTokenException：无法添加窗口 - 令牌[email protected]无效;你的活动正在运行？

读WindowManager$BadTokenException

按如下步骤

final ProgressDialog dialog = ProgressDialog.show(obs_bgw.this,null, "Please Wait");

ProgressDialog应GLOBAL变量。

添加方法。

@Override 
public void onPause() { 
super.onPause(); 
if (dialog.isShowing()) 
{ 
    dialog.dismiss(); 
}

很好的[百万猴编程风格]（https://en.wikipedia.org/wiki/Programming_by_permutation）的例子...显然它不会像'obs_bgw.this = = this'在这种情况下 – Selvin

之外创建进度对话框实例，并展示它，而调用web服务。一旦完成任务，隐藏进度对话框。在顶部

private ProgressDialog progressDialog;

申报对话框在OnCreate创建它的实例。

progressDialog = new ProgressDialog(this); 
    progressDialog.setCancelable(false); 
    progressDialog.setCanceledOnTouchOutside(false); 
    progressDialog.setTitle("Loading...");

显示web服务调用方法中的对话框。

public void sendjsonrequest() { 

progressDialog.show(); 

}

在onResponse和onErrorResponse中，关闭对话框。

dialog.dismiss();

[百万猴编程风格]的另一个例子（https://en.wikipedia.org/wiki/Programming_by_permutation）你知道他的代码吗？他在60秒后再次调用sendjsonrequest。 callinf显示dismised对话框不是一个好习惯......真正的问题是处理程序 - 它仍然工作后活动关闭 – Selvin

哦，我还没有看到。 –

请检查以下条件

对于ProgressDialog中的onPause /的onDestroy

if (progressDialog != null) progressDialog.dismiss();

对于在onPause /的onDestroy

删除处理程序回调

if (handler != null && runnable != null) { 
      handler.removeCallbacks(runnable); 
     }

请这样写你的条件，否则处理程序将采取多个实例：

Runnable runnable; 
    final Handler handler = new Handler(); 
    if (runnable != null) { 
    handler.removeCallbacks(runnable); 
    } 
    runnable = new Runnable() { 
      @Override 
      public void run() { 
       sendjsonrequest(); 
       handler.postDelayed(this, 60000);//60 second delay 
      } 
     }; 
     handler.postDelayed(runnable, 60000);
