即时启动我的应用程序时，有时有问题。不时屏幕一直是黑色，我必须等待10分钟。我没有得到一个错误消息，并且logcat中这样说：

i'm having sometimes problems when launching my app. From time to time the screen stays black and i have to wait 10 minutes. I don't get an error message and the logcat says this:

推荐答案

我想我找到了问题所在。我使用的服务和广播。一个服务发送一个广播到其他服务。该BroadcastReceiver的做一个长期的任务，其中包括一个HTTP连接。该广播有10秒的空闲超时，我的任务运行时间超过了10秒somtimes。所以应的BroadcastReceiver开始一个新的线程，以便它可以立即返回。

I think i found out what the problem is. I use services and broadcasts. One service sends a broadcast to another service. The BroadcastReceiver does a long task which includes a http connection. The Broadcast has an idle timeout of 10 secs and my task runs longer than 10 secs somtimes. So the BroadcastReceiver should start a new thread so that it can return immediately.
