android - cordova/phonegap 推送通知 unregister() 即使在关闭互联网的情况下也会返回成功

Question

我正在使用 Phonegap 推送插件 ( https://github.com/phonegap-build/PushPlugin ) 并具有以下功能(以及成功和错误回调)，当我通过切换关闭通知时调用该功能

function pushNotificationOFF() {
    var pushNotification = window.plugins.pushNotification;
    pushNotification.unregister(pushNotificationOffSuccess,
        pushNotificationOffError);
}

function pushNotificationOffSuccess() {
    alert("Noticications are OFF");
}

function pushNotificationOffError() {
    alert("Error turning noticications off");
}

在 iOS7 和 Android 4.x 上，在互联网关闭(手机和 wifi)的情况下调用成功函数，我本以为会触发错误回调？

我在这里缺少什么？如何确保您不会向在设备离线时关闭它们的人发送通知？

SUMMARY OF TODAY

seems IOS does turn off notifications (when back online again) if toggle was changed while offline
android seems to do it also, provided 
a) there is time (ie 30 min between going online again, and sending push)
b) you background app instead of closing it, after changing the toggle

如 Android documentation 所述注销不会立即发生。相反，取消注册可能需要 5 分钟才能传播。这 5 分钟内发生的事情是

During this time messages may be rejected due to the state of being unregistered, and after all this, messages may still go to the wrong user.

因此，您的注销意愿已成功收到，流程已启动，因此调用了成功回调。

这是从负责响应 JS 的 PushPlugin.java 取消注册调用的代码

GCMRegistrar.unregister(getApplicationContext());
Log.v(TAG, "UNREGISTER");
result = true;
callbackContext.success();

如您所见，它实际上可能失败的唯一情况是在 GCMRegistrar.unregister 上，它甚至不等待 GCM 服务器响应“好的，未注册”，从而导致总是返回成功。
