消息推送连接问题

Android Studio,   参考demo，编译出来APK可运行

手机畅享5S  Android 5.1, EMUI3.1 Lite, 已更新到最新华为移动服务

在Service调用推送初始化
public static void startPushService(Context c) {
    context = c;
    hwApi = new HuaweiApiClient.Builder(context)
            .addApi(HuaweiPush.PUSH_API)
            .addConnectionCallbacks(pushHw)
            .addOnConnectionFailedListener(pushHw).build();
    hwApi.connect();
}
连接有错误：@Override
public void onConnectionFailed(ConnectionResult result) {
    PluginLog.i(TAG, "onConnectionFailed, ErrorCode: " + result.getErrorCode() );
}
输出：PushHw: onConnectionFailed, ErrorCode: 907135000


另外，有大量这样的错误
