解决方案

您onRecieve正在改变的意图，并试图用它来启动服务。你应该用一个新的意图来启动服务，而不是

I am trying to understand when device is connected to internet.

but I get this error :

03-12 20:35:06.801: E/BroadcastReceiver(28892): BroadcastReceiver trying to return result during a non-ordered broadcast

---

My BroadcastReceiver :

public class ConnectivityChangeReceiver extends BroadcastReceiver {


@Override
public void onReceive(Context context, Intent intent) {


    // Explicitly specify that which service class will handle the intent.
    ComponentName comp = new ComponentName(context.getPackageName(),
            YourService.class.getName());

    intent.putExtra("isNetworkConnected",isConnected(context));
    context.startService((intent.setComponent(comp)));


    setResultCode(Activity.RESULT_OK);
}

public  boolean isConnected(Context context) {
       ConnectivityManager connectivityManager = ((ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE));
       NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
       return networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected();
 }

}

My service :

public class YourService extends IntentService{

public YourService() {
    super("Test");
    // TODO Auto-generated constructor stub
}

@Override
protected void onHandleIntent(Intent intent) {
  Bundle extras = intent.getExtras();
  boolean isNetworkConnected = extras.getBoolean("isNetworkConnected");
  // your code
  if(isNetworkConnected){
      Log.e("TAG", "Yes");
  }

}

}

</manifest>

解决方案

Your onRecieve is altering the intent and trying to use it to start a service. You should use a new intent to start the service instead.
