Question

我正在开发一个应用程序，因为我必须将 GCM 的注册 ID 从应用程序发送到我自己的服务器我写了一些代码它不起作用请告诉我哪里出错了

myAsynTask 类

语境语境；

    public static final String EXTRA_MESSAGE = "message";
    public static final String PROPERTY_REG_ID = "registration_id";

    String SENDER_ID = "538459826415";

    static final String TAG = "GCMDemo";
    GoogleCloudMessaging gcm;

    String msg;


    String regid;

@Override
protected Void doInBackground(DetailsDTO... params) {
    // TODO Auto-generated method stub
    httpClient  = new DefaultHttpClient();
    httpPost = new HttpPost(TrafficConstants.USER_REG_URL);


    try{
    gcm = GoogleCloudMessaging.getInstance(context);
    regid = gcm.register(SENDER_ID);
    msg = "Dvice registered, registration ID=" + regid;
    Log.d("111", msg);

    }
    catch(IOException e){
        e.printStackTrace();
    }

    try{
    arrayList = new ArrayList<NameValuePair>(=1);

    arrayList.add(new BasicNameValuePair("rigid", regid));

    httpPost.setEntity(new UrlEncodedFormEntity(arrayList));
    HttpResponse response = httpClient.execute(httpPost);
    }
    catch(Exception e){
        e.printStackTrace();
    }
    return null;

}

Answer 1

看来你的发件人id不正确

Supply a project name and click Create.

Once the project has been created, a page appears that displays your project ID and project number.

For example, Project Number: 670330094152.

您应该在 Google API 控制台内的项目页面中激活 GCM 服务和

Server Application Key
Android Application Key

选项也生成了。

然后在 Android Application Key 中，您应该使用分号分隔散列码和您的应用程序包名称。

AA:98:0C:AA:03:BD:E7:DA:AA:4A:FA:AF:73:3F:72:E7:D4:11:4S:B1;com.example.myapp

项目编号是发件人 ID。

检查一下，然后重试。
