问题描述
我的服务器将消息发送到为200的响应code中的GCM塞雷尔语，但我的OnMessageReceiver是没有得到因此被称为即时通讯没有得到消息。

解决方案Replace reciever in your Manifest by receiver. Moreover, make sure your app successfully got the token (registration device Id). Hope this helps!
My Manifest:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="schemas.android/apk/res/android" package="com.example.gcmclient" > <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <permission android:name="com.example.gcm.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <receiver android:name="com.google.android.gms.gcm.GcmReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <category android:name="com.example.gcm" /> </intent-filter> </receiver> <service android:name=".service.GcmService" android:exported="false"> <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> </intent-filter> </service> <service android:name=".service.LoggingService" android:exported="false" /> <activity android:name=".MainActivity" android:label="@string/app_name" android:clearTaskOnLaunch="false" android:finishOnTaskLaunch="true"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>Moreover, check your sever-side response after sending. Perhaps you will get response message like the following if GCM message sucessfully sent:
{"multicast_id":6371085842931382567,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1240780242421810%4c427ca6f9fd7ecd"}]}About getting token, firstly, I check SharedPreferences, if empty, get token (device registration id) from Google server. Token will be stored in SharedPreferences for other use / providing to server-side app.
public class MainActivity extends Activity { Context mContext = this; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ... SharedPreferences appPrefs = mContext.getSharedPreferences("com.example.gcmclient_preferences", Context.MODE_PRIVATE); String token = appPrefs.getString("token", ""); if (token.isEmpty()) { try { getGCMToken("0123456789"); // Project ID: xxxx Project Number: 0123456789 at console.developers.google/project/... } catch (Exception ex) { ex.printStackTrace(); } } ... } ... private void getGCMToken(final String senderId) throws Exception { new AsyncTask<Void, Void, Void>() { @Override protected String doInBackground(Void... params) { String token = ""; try { InstanceID instanceID = InstanceID.getInstance(mContext); token = instanceID.getToken(senderId, GoogleCloudMessaging.INSTANCE_ID_SCOPE, null); if (token != null && !token.isEmpty()) { SharedPreferences appPrefs = mContext.getSharedPreferences("com.example.gcmclient_preferences", Context.MODE_PRIVATE); SharedPreferences.Editor prefsEditor = appPrefs.edit(); prefsEditor.putString("token", token); prefsEditormit(); } Log.i("GCM_Token", token); } catch (IOException e) { e.printStackTrace(); } return null; } }.execute(); } }
