在运行猴子测试时，我也遇到了windowleaks的问题。logcat在下面。

我的活动是AppCompatActivity。我用下面的代码在活动中解决了它。

@Override
public boolean dispatchKeyEvent(KeyEvent event) {
    // added by sunhang : intercept menu key to resove a WindowLeaked error in monkey-test.
    if (event.getKeyCode() == KeyEvent.KEYCODE_MENU) {
        return true;
    }
    return super.dispatchKeyEvent(event);
}

当您尝试在活动有效完成后显示警报时，会出现“活动已泄漏最初添加的窗口…”错误。

AFAIK，你有两个选择:

重新考虑登录alert:在实际退出activity之前调用对话框上的dismiss()。 将对话框放在不同的线程中，并在该线程上运行它(与当前活动无关)。

比之前的答案晚得多，在2022年人们使用Kotlin时，当Kotlin协程试图从错误的(非main)协程上下文修改弹出窗口时，我们也得到了错误。

产生错误:

CoroutineScope(Dispatchers.IO).launch{
    someCodeThatNeedsOtherContext()
    someViewBinding.someAttribute = someValue // We get the error here
}

不产生错误:

CoroutineScope(Dispatchers.IO).launch{
    someCodeThatNeedsOtherContext()
    CoroutineScope(Dispatchers.Main).launch{
        someViewBinding.someAttribute = someValue // No error here
    }
}

如果你在doInBackground()函数中有一个错误，并且有这样的代码，就会出现这种情况。

最后尝试添加对话。首先检查并修复doInBackground()函数

protected void onPreExecute() {
     super.onPreExecute();
     pDialog = new ProgressDialog(CreateAccount.this);
     pDialog.setMessage("Creating Product..");
     pDialog.setIndeterminate(false);
     pDialog.setCancelable(true);
     pDialog.show();

 }

 protected String doInBackground(String...args) {
     ERROR CAN BE IS HERE
 }

 protected void onPostExecute(String file_url) {
     // dismiss the dialog once done
     pDialog.dismiss();

根据我的问题是，你正在尝试调用一个对话框后，一个活动正在完成，所以根据我，你可以做的是给一些延迟使用处理程序，你的问题将得到解决，例如:

 Handler handler=new Handler();
     handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                     dialog.show();
                     //or
                     dialog.dismiss();

                }
            },100);

你必须在AsyncTask的onPreExecute方法中创建Progressdialog对象，你应该在onPostExecute方法中解散它。
