我正在嘗試將推送通知功能添加到我的應用程序,但我有奇怪的問題。註冊 - 從Android GCM取消註冊設備
在我第一次嘗試,我得到了設備的REGID;但在該設備試圖從GCM自行註銷之後;事實上,它成功了,因爲我失去了REGID,但不是我再也得不到它了。
在LogCat中,我看到了這些行。

我試着將GCM Demo Application的代碼實現到我的應用程序中,所以這裏是代碼。
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
registerReceiver(mHandleMessageReceiver, new IntentFilter(DISPLAY_MESSAGE_ACTION));
final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
// Automatically registers application on
// startup.
GCMRegistrar.register(this, SENDER_ID);
} else {
Log.v(TAG, "Already registered");
// Device is already registered on GCM, needs to
// check if it is
// registered on our server as well.
if (!GCMRegistrar.isRegisteredOnServer(this)) {
// Try to register again, but not in the UI
// thread.
// It's also necessary to cancel the thread
// onDestroy(),
// hence the use of AsyncTask instead of a
// raw thread.
final Context context = this;
mRegisterTask = new AsyncTask<Void, Void, Void>() {
mRegisterTask.execute(null, null, null);
}
}
}
如何檢查設備是否在GCM./ – 2013-04-13 08:07:52
最後絃樂的RegID = GCMRegistrar.getRegistrationId(本)註冊與否;這條線給你答案。如果是空設備未註冊,則另行註冊。 – 2013-04-13 19:20:03
