我正在开发我的第一款Android应用.我的应用程序中有三个活动,用户来回切换频繁.我还有一个远程服务,它处理一个telnet连接.应用程序需要绑定到此服务才能发送/接收telnet消息.
编辑 感谢BDLS提供的信息.我已根据您对使用bindService()作为独立函数或在startService()之间的区别的说明重新编写了我的代码,现在我只是在使用后退按钮之间循环时间歇性地获取泄漏错误消息活动.
我的连接活动有以下onCreate()和onDestroy():
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*
* Initialize the ServiceConnection. Note that this is the only place startService() is run.
* It is also the only time bindService is run without dependency on connectStatus.
*/
conn = new TelnetServiceConnection();
//start the service which handles telnet
Intent i = new Intent();
i.setClassName( "com.wingedvictorydesign.LightfactoryRemote", "com.wingedvictorydesign.LightfactoryRemote.TelnetService" );
startService(i);
//bind to the service
bindService(i, conn, 0);
setContentView(R.layout.connect);
setupConnectUI();
}//end …我正在编写一个通过wifi连接到telnet服务器的应用程序.我有一个管理套接字连接的服务.一切正常,但是当手机休眠时,它会断开wifi无线电,导致套接字连接中断(并抛出SocketException).
我觉得我应该能够设置一个广播接收器,当wifi网络连接丢失时调用onResume()方法,这将允许我优雅地关闭套接字,并在网络立即重新打开它重新连接.但我在文档或搜索中找不到类似的东西.
服务代码在这里,如果你需要它,感谢您的帮助,我真的很感激!
