我有这个例外：

            Intent notificationIntent = new Intent(context, ProblemioActivity.class);

            // set intent so it does not start a new activity
            notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
            PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);        
            Uri defaultSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);            

             Notification notification = new NotificationCompat.Builder(context)
             .setContentTitle(title)
             .setContentText(message)
             .setContentIntent(intent)
             .setSmallIcon(icon)
             .setLights(Color.YELLOW, 1, 2)
             .setAutoCancel(true)
             .setSound(defaultSound)
             .build();

            notificationManager.notify(0, notification);
    }     
}

崩溃发生在这一行：

generateNotification(ctxt, extras.getString("message"), "New Message");

我应该把这条线换成这样的：

if ( android.os.Build.VERSION.SDK_INT >= 8 )
{

}

在我的清单中，我允许所有这样的 sdk 版本：

4

这是 rev11 之前的 android-support-v4.jar 中的一个已知错误。

获取最新的 android-support-v4.jar：

  1. 从您的 IDE 打开 SDK 管理器
  2. 检查Android Support Library并单击安装包
  3. 导航到yourSdkFolder/extras/android/support/v4并复制android-support-v4.jar
  4. 导航到android-support-v4.jar项目中的位置，然后粘贴，替换旧版本
