GCM为gettoken（）发送java.io.IOException异常：超时 [英] GCM getToken() sends java.io.IOException: TIMEOUT

问题描述

我实现推送通知，但我收到TIMEOUT异常调用时为gettoken。

I am implementing push notifications, but I receive TIMEOUT exception when calling getToken.

我这里设置GCM 应用和SENDER_ID恰好提供的之一。此外，服务器API密钥保存在后端的部分。

I've set the app for GCM here and SENDER_ID is exactly the one provided. Also, Server API key was saved on the backend part.

有为gettoken请求有限数量？测试推送通知，当我在第一次尝试几次没有任何问题。

Is there a limited number of getToken requests? I had no problems at first several attempts when testing push notifications.

new AsyncTask<Void, Void, Void>(){

        @Override
        protected Void doInBackground(Void... params) {
            try {

                InstanceID instance = InstanceID.getInstance(mContext);

                String registrationId = instance.getToken(Constants.GCM_SENDER_ID,
                        GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

                SharedPreferences sp = mContext.getSharedPreferences(Constants.TOKEN_DATA, Context.MODE_PRIVATE);
                SharedPreferences.Editor editor = sp.edit();
                editor.putString(Constants.REGISTRATION_ID, registrationId);
                editor.commit();

                NotificationsRegister.getInstance(mContext).register(registrationId);
            } catch(IOException e) {
                e.printStackTrace();
            }

            return null;
        }
    }.execute();

推荐答案

我就遇到了这个问题，今天，这里是我做过什么来解决。

I ran into this problem today and here's what I did to troubleshoot.

首先，试图获得令牌的时候我还用我自己的发件人ID。所以不是，我尝试使用发件人ID从谷歌提供了的getString（R.id.gcm_defaultSenderId）

First, I also was using my own sender ID when attempting to get the token. So instead, I tried using the sender ID from the examples Google provides getString(R.id.gcm_defaultSenderId)

在我这样做，我开始得到一个不同的错误信息 SERVICE_NOT_AVAILABLE

Once I did this, I started to get a different error message SERVICE_NOT_AVAILABLE

有，解决这几款SO问题，但帮我出了一个是这个。

There are several SO questions that address this, but the one that helped me out was this one.

我关掉WiFi和使用我的手机上4G的连接，并将其与两个 gcm_defaultSenderId 的工作和我自己的发件人ID。

I turned off WiFi and used a 4G connection on my phone and it worked with both the gcm_defaultSenderId and my own sender ID.
