我正在使用ACRA报告应用程序崩溃.我收到一条View not attached to window manager错误消息,并认为我已通过pDialog.dismiss();在if语句中包装来修复它:

if (pDialog!=null) 
{
    if (pDialog.isShowing()) 
    {
        pDialog.dismiss();   
    }
}

它减少了View not attached to window manager我收到的崩溃数量,但我仍然得到一些,我不知道如何解决它.

错误信息:

代码段:

class LoadAllProducts extends AsyncTask<String, String, String> …

所以我调用了活动GameActivity.java,在这个活动中我称之为DialogAnswer.show()简单显示屏幕上的一些图片.

这是我的DialogAnswer.java班级

public class DialogAnswer extends Activity {

   private static ImageView resultImage;
   private static Dialog dialog = null;

   public static void show(Context context, boolean fCorrect) {

       dialog = new Dialog(context, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
       dialog.setContentView(R.layout.dialog);
       resultImage = (ImageView) …

任何人都可以向我解释为什么会出现这种错误,或者更好的我如何处理它？我无法重现它.这是1000次中发生的错误之一.

背景:用户正在尝试登录,显示进度对话框,在异步任务中发送http请求,取消进度对话框.发生错误,应用FC.

LoginActivity.java

 255:   private void dismissProgress() {  
 256:     if (mProgress != null) {  
 257:         mProgress.dismiss();  
 258:         mProgress = null;  
 259:     }  
 260:   }

我从我的应用程序中得到了错误报告,所有这些都是一样的.这真的很烦人,因为在我的测试设备(HTC Wildfire,Galaxy S I-II-III,Galaxy Mini,Galaxy Tab 10)中,这个错误从未发生过,对我或我的测试伙伴来说,看起来像用户做了一些与我们不同的事情.

因为这个我不能给你太多有关情况的信息,有一件事我看到,它是一个对话框的解雇,我实际上从来没有通过代码调用.

这是错误:

有人能帮助我吗？由于这个问题我每周得到30-40个错误报告,我真的无法弄清楚为什么会这样.

所有建议将不胜感激.谢谢,

警告The view is not attached to a window意味着什么？在尝试调试我的游戏时,我经常在Logcat中获取它.

确切的输出:

12-27 18:14:12.415: W/View(16827): The view is not attached to a window

我已经搜索过这个警告,但却找不到任何内容.我得到的只是关于Window Manager的错误,这不是我在这里得到的.我想知道这个警告的原因,只是为了确认它是否与FPS下降有关？

我在发布的应用程序中收到此错误，只有客户端收到此错误。我已经多次尝试复制同样的错误，但没有成功。我也已经尝试在所有有 Dialog 但也没有解决的位置使用下面的代码。

if (dialog.isShowing ()) {
    dialog.dismiss ();
}

我越来越知名了java.lang.IllegalArgumentException: View not attached to window manager.目前已知的解决方案是使用空的try-catch块忽略错误.但它是否有一个更程序员友好的解决方案？例如

if (dialog.isAttached())
  dialog.dismiss();

当然,如果Android SDK有一个没有失败的功能会更好(因为如果无法避免它,API为什么会失败？):

dialog.tryDismiss();

或者空的try-catch块在架构上是否合理？或者它只是一个糟糕或不完整的API的解决方法？

我正在开发一个Android应用程序,其中即时通讯使用异步任务和后执行方法,当我关闭进度对话框时,异常即将到来且应用程序正在强制关闭.

例外情况是:
