java - GCM SERVICE_NOT_AVAILABLE 错误

Question

我在我的 android 应用程序中使用 GCM，当我尝试向 GCM 注册设备时(使用命令 gcm.register(SENDER_ID))我收到 SEVICE_NOT_AVAILABLE 错误，我尝试了某人建议here (公认的解决方案)我确实获得了注册 ID。

为什么会这样？

注册方法:

private void registerInBackground() {   
    new AsyncTask<Void, Void, String>() {

        @Override
        protected String doInBackground(Void... params) {
            String message = "";

            try {
                if (gcm == null) {
                    gcm = GoogleCloudMessaging.getInstance(context);
                }
                regid = gcm.register(SENDER_ID);
                message = "Device registered, registration ID=" + regid;

                Log.d("SMARTGAN_PLAY", "register completed");

                // send registration id to the server
                sendRegistrationIdToServer();

                // Persist the regID - no need to register again.
                storeRegistrationId(context, regid);
            } catch (IOException e) {
                message = "Error:" + e.getMessage();
            }
            return message;
        }

    }.execute(null, null, null);
}

我认为问题出在您的 Google API 项目中提到的允许的 IP 地址。请检查项目的详细信息，如果 restrict use to IP address 下存在 IP 地址，请将其删除。我遇到了类似的问题。
