模擬器測試最低需求4.2.2
1.Google API Library下載
開發環境請先下載Google APIs的library,把
2.在AndroidManifest.xml,設定google api
然後在AndroidManifest.xml裡的Application加入
<meta-data android:name=“com.google.android.gms.version" android:value="@integer/google_play_services_version" />
3.建立Google APIs專案,取得伺服器應用程式的金鑰
請先到Google APIs建立專案給GCM用,並建立一組「伺服器應用程式的金鑰」,產生的金鑰用來讓PHP發送Message用的。
https://console.developers.google.com/project
4.設定AndroidManifest.xml新增App背景服務與權限
在AndroidManifest.xml裡,設定以下權限
<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.app.yourapp.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <uses-permission android:name=“com.app.yourapp.permission.C2D_MESSAGE" />
在
同樣設定一些服務
<receiver android:name=".GcmBroadcastReceiver” android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter > <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <category android:name=“com.app.yourapp" /> </intent-filter > </receiver= > <service android:name=".GcmIntentService" />
5.主程式MainActivity
宣告一個字串,這串數字是Google APIs專案中的專案編號。
String SENDER_ID = “123456789”;
在OnCreate加入,主要判斷是不是有playerServices,及App有沒有取得RegistrationId。
context = getApplicationContext(); // GCM registration. if (checkPlayServices()) { gcm = GoogleCloudMessaging.getInstance(this); regid = getRegistrationId(context); if (regid.isEmpty()) { registerInBackground(); } Log.d(TAG,"Regid"+regid); } else { Log.d(TAG, "No valid Google Play Services APK found."); }
新增GcmIntentService繼承IntentService, 處理App通知收到後要做什麼事。
實際程式碼請參考Android Developer
新增GcmBroadcastReceiver繼承WakefulBroadcastReceiver, 這支程式要幹嘛不曉得,應該是常駐在背景,等待接收通知用的(請有緣人解釋給我聽)。
6.完成以上步驟,實際測試。
也可以用Simulator測試,只要把Simulator的Target設定成Google Api即可。

//------------------------------
echo $result;
