如何清除通知，如果活动崩溃？ [英] How to clear a notification if activity crashes?

问题描述

在我的应用程序，我创建的FLAG_ONGOING_EVENT标志设置为这样的通知。

In my app, I'm creating a notification with the FLAG_ONGOING_EVENT flag set as such..

Notification notification = new Notification(iconId, text, System.currentTimeMillis());  
notification.flags |= Notification.FLAG_ONGOING_EVENT;

我取消在的onDestroy通知，但如果调用的onDestroy在我的应用程序崩溃，有没有什么办法让我通知走开？

I'm cancelling the notification in onDestroy, but if my app crashes before calling onDestroy, is there any way to have my notification go away?

推荐答案

一切都崩溃了，甚至是谷歌应用程序。我用 Thread.setUncaughtExceptionHandler（）和下面的处理程序code：

Everything crashes, even Google applications. I use Thread.setUncaughtExceptionHandler() and the following handler code:

package my.package;

import java.lang.Thread.UncaughtExceptionHandler;

import android.app.NotificationManager;
import android.content.Context;

public class CrashHandler implements UncaughtExceptionHandler
{
  private static final int NOTIFICATION_ID = 12345;

  private UncaughtExceptionHandler defaultUEH;
  private NotificationManager notificationManager;

  public CrashHandler(Context context)
  {
    this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
  }

  public void uncaughtException(Thread t, Throwable e)
  {
    if (notificationManager != null)
    {
      try
      {
        notificationManager.cancel(NOTIFICATION_ID);
      }
      catch (Throwable ex)
      {
        ex.printStackTrace();
      }
    }
    notificationManager = null;

    defaultUEH.uncaughtException(t, e);
  }
}
