有一次,我有一个问题,你们真的很有帮助.所以我再次遇到另一个问题......:/

我正在运行扩展BroadcastReceiver的自定义NetworkReceiver.我想检测手机何时有互联网连接,以便我可以随时启动服务.我已经阅读了很多主题和所有主题或多或少的提示,以下代码对我不起作用:

public class NetworkReceiver extends BroadcastReceiver {

private static final String tag = NetworkReceiver.class.getSimpleName();

@Override
public void onReceive(Context context, Intent intent) {
    Log.i(tag,"****** NetworkReceiver // onReceive()");

    boolean noConnection = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);

    if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
        Log.i(tag,"****** NetworkReceiver // Network Down?: " + intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false));
    }

    // TODO Bug: Never stops the service. Stays always connected!
    if(noConnection) {
        Log.i(tag,"****** NetworkReceiver // Stopping Service...");
        context.stopService(new Intent(context, FetchService.class));
    } else {
        Log.i(tag,"****** NetworkReceiver // Starting Service!");
        context.startService(new Intent(context, FetchService.class));
    }
}

我遇到的问题是logcat总是返回NetworkDown?: …
