我使用教程从C2DM Tutorial，当我使用此代码在我的应用程序运行（我的应用程序有多个线程，并运行此C2DMessaging.register（getApplicationContext（），SENDERS_EMAIL_ID）;在一个多线程提供ANR的C2DM广播意向。如何避免它？
。但是，即使我在单独的线程上运行此操作后，我也收到了下面的错误消息，并弹出了一个ANR，以为我看到在我的背景中，我的应用程序开始完美无缺了!!!!
我启动C2DM.register （...）是
new Thread() {
public void run() {
try{
C2DMessaging.register(getApplicationContext(), SENDERS_EMAIL_ID);
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
}
}.start();
我这样做的错误日志是

谢谢。

确定。我添加了一些代码。能否请你帮忙。谢谢 – Sana
另外我想指出，我确实收到id成功并将regId发布到服务器。 – Sana
它的有趣，错误停止！唷！ – Sana
