Google Cloud Messaging(Androidメッセージプッシュ技術)(二)
9347 ワード
(一)前の章では、Androidメッセージプッシュの基本的な流れと必要ないくつかのキーの値を述べました.
ここではGoogle Cloud Messaging(GCM)の使い方を紹介します.
GCMの実現について、googleが早期に使っているインターフェースはこの文章を参考にしてもいいです.文章の中ですでに十分に紹介しました.古いインターフェースの下でどのようにGCMを実現しますか?

以下はこの記事のコードの一部の変更です.
Androidクライアントのコードは以下の通りです.
https://github.com/yuxiaohui78/Google_Cloud_Messaging/tree/master/GCMClient Onmobile_deprecated_version
サードパーティサーバをシミュレートするメッセージ送信部分コード:
https://github.com/yuxiaohui78/Google_Cloud_Messaging/tree/master/GCMSendOPC
(二)googleは古いインターフェースを廃棄することを決めました.そこで、新しいインターフェースの実現方法を紹介します.
新しいAppleインターフェースはgoogle service 3.1+のサポートが必要です.
1.Android Manifest.xmlにサポートを追加し、クラウドメッセージの受信を許可するcomple.google.android.c2 dm.permission.RECEIVE
https://github.com/yuxiaohui78/Google_Cloud_Messaging/tree/master/GCMClient Onmobile
コードを使う方法は簡単で、DemoActivity.javaのSENDER_を使うだけです.IDを前の章のProject Numberに置き換えれば使えます.
次の章では、Google Cloud Messagingのテスト方法を紹介します.
