Question

我已经为我的应用程序选择了Google Cloud Messaging，到目前为止，它完全适用于Google API 17,18,19＆amp; 21.但是，在Google API 16上，我在注册级别获得了一个TIMEOUT。以前有人遇到过这个吗？我正在使用Google推荐的AsyncTask。

我的代码：

private class PrefetchData extends AsyncTask<Void, Void, Void> {

@Override
protected void onPreExecute() {
    super.onPreExecute();
    // before making http calls         
}

@Override
protected Void doInBackground(Void... arg0) {

try{

    // ...

    // register device to Google Cloud Messaging if not already done
    if(gcmDeviceRegID.equals("")){
        gcm = GoogleCloudMessaging.getInstance(getApplicationContext());
        gcmDeviceRegID = gcm.register(PROJECT_NUMBER);
    }

}

catch( Exception e ){
    e.printStackTrace();
    return null;
}

return null;

}

//...

如您所知，SplashScreenActivity.java:104就是这一行：

gcmDeviceRegID = gcm.register(PROJECT_NUMBER);

知道如何解决这个问题吗？谢谢！

根据Arthur Thompson的评论，这是通过使用新推荐的方式注册到GCM（从2015年6月28日开始）来解决的：

             JSONObject datamsj = (JSONObject) args[0];
             try {
                    TimeZone tz = TimeZone.getTimeZone("UTC");
                    TimeZone tz2 = TimeZone.getTimeZone("America/Bogota");
                    Calendar cal = Calendar.getInstance(tz);
                    SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss zZ (z)");
                    sdf.setCalendar(cal);
                    cal.setTime(sdf.parse(datamsj.getString("fc")));

                    cal.setTimeZone(tz2);
                    Date date = cal.getTime();
                    DateFormat df = new SimpleDateFormat("HH:mm a");
                    messageTextDate = df.format(date);
                    messageText = datamsj.getString("msj");
                } catch (Exception e) {
                    e.printStackTrace();
                    return;
                }

而不是

InstanceID instanceID = InstanceID.getInstance(getApplicationContext());
gcmDeviceRegID = instanceID.getToken(PROJECT_NUMBER,GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
