Question

我想在用户点击按钮后取消注册GCM。我尝试使用以下代码进行取消注册，但即使在完成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();
}

Answer 1

首先，要取消注册，您应该使用以下代码：

从GCM取消注册

要从GCM取消注册，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，您输入SENDER_ID而不是“app”。

其次，我不确定GCMRegistrar.unregister(this)是做什么的（我不使用它），但我认为这是一个与上面3行代码相同的捷径，所以没有指向两者。

首先，假设您使用的代码类似于我用于IntentService的代码（我有一个扩展Google C2DMBaseReceiver的类），则在取消注册完成时应调用onUnregistered 。如果未调用，您的设备仍会注册。我建议您使用调试器运行应用程序，并查看调用的方法。

Answer 2

在2行以下取消注册您的GCM。

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

取消注册后的GCM仍会收到通知
