安卓实时更新

Question

我正在创建一个使用JSON与Web服务器通信的Android游戏。当有人开始与另一个用户的新游戏时，我希望该用户获得立即通知。到目前为止，我已经发出了通知并且它们有效，但它只检查我登录游戏时，如何创建实时更新即使游戏关闭，也许也会以一分钟的间隔进行检查？

C2DMMessageReceiver

public class C2DMMessageReceiver extends BroadcastReceiver {
@Override

    String action = intent.getAction();
    Log.w("C2DM", "Message Receiver called");

}
public void register(View view) {
    Intent intent = new Intent("com.google.android.c2dm.intent.REGISTER");
    intent.putExtra("app",PendingIntent.getBroadcast(this, 0, new Intent(), 0));
    intent.putExtra("sender", "[e-mail]");
    startService(intent);
}

现在，如果我开始与某人玩游戏，我有一个将信息发送到服务器的类。那我该怎么做呢？

您可以通过

实现Service来实现您想要的。 但是，发出HTTP请求以每分钟获取状态将消耗电池。 我建议研究C2DM以便向客户端发送推送通知。
