用户单击按钮后，我想取消注册 GCM。我尝试了以下代码来取消注册，但即使在所有这些初始化之后，我仍然设法将通知推送到设备。如果我在这里遗漏任何东西，请告诉我。

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch(item.getItemId()) {
        case R.id.options_logout:
            ServerUtilities.unregister(getApplicationContext(), ServerUtilities.registrationID);
            unRegisterGCM();
            return true;
        case R.id.options_exit:
            finish();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

@Override
protected void onDestroy() {
    Log.i(TAG,"onDestroy.........");
    helper.close();
    if (mRegisterTask != null) {
        mRegisterTask.cancel(true);
    }
    unregisterReceiver(mHandleMessageReceiver);
    super.onDestroy();
}

public void unRegisterGCM(){
    Intent unregIntent = new Intent("com.google.android.c2dm.intent.UNREGISTER");
    unregIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
    startService(unregIntent);

    Intent intent = new Intent(MessageList.this, LoginScreen.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(intent);
    finish();
}

首先，要取消注册，您应该使用以下代码：

从 GCM 注销

要从 GCM 注销，请执行以下操作：

Intent unregIntent = new Intent("com.google.android.c2dm.intent.UNREGISTER");
unregIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
startService(unregIntent);

在您的代码中，您放置了 SENDER_ID 而不是“app”。

其次，我不确定是什么GCMRegistrar.unregister(this)（我不使用它），但我认为这是一个捷径，与上面的 3 行代码相同，所以调用两者没有意义。

第三，假设您使用的代码与我用于 IntentService 的代码相似（我有一个扩展 Google 的类C2DMBaseReceiver），onUnregistered应该在取消注册完成时调用。如果未调用，则您的设备仍处于注册状态。我建议您使用调试器运行应用程序并查看调用了哪些方法。

把下面的 2 行注销您的 GCM。 

GCMRegistrar.unregister(NotificationsActivity.this);
GCMRegistrar.onDestroy(NotificationsActivity.this);
