Android 四大组件之再论service

service常见的有2种方式，本地service以及remote service。

这2种的生命周期，同activity的通信方式等，都不相同。

关于这2种service如何使用，这里不做介绍，只是介绍一些被遗漏的地方

1.远程Service（AIDL方式）

package com.joyfulmath.samples.basecontrol;import android.app.Activity;import android.content.ComponentName;import android.content.Intent;import android.content.ServiceConnection;import android.os.IBinder;import android.os.RemoteException;import com.joyfulmath.samples.R;import com.joyfulmath.samples.TraceLog;import org.androidannotations.annotations.Click;import org.androidannotations.annotations.EActivity;/** * Created by Administrator on 2016/10/11 0011. * service connect activity samples */@EActivity(R.layout.activity_connect_service)public class ServiceConActivity extends Activity {  private ISamplesAidlInterface binder;  private ServiceConnection connection = new ServiceConnection() {    @Override    public void onServiceConnected(ComponentName name, IBinder service) {      TraceLog.i();      binder = ISamplesAidlInterface.Stub.asInterface(service);      if(binder!=null)      {        try {          binder.registerCallBack(mCallBack);        } catch (RemoteException e) {          e.printStackTrace();        }      }    }    @Override    public void onServiceDisconnected(ComponentName name) {      TraceLog.i();      binder = null;    }  };  private ICallBack.Stub mCallBack = new ICallBack.Stub() {    @Override    public void onServiceStateChanged(int s) throws RemoteException {      TraceLog.i(String.valueOf(s));    }  };  public void bindSamplesService()  {    TraceLog.i();    Intent intent = new Intent(this,ServiceSamples.class);//    intent.setAction("com.joyfulmath.service.samples");    bindService(intent,connection,BIND_AUTO_CREATE);  }  public void unBindSamplesService()  {    TraceLog.i();    if(binder!=null)    {      try {        binder.unRegisterCallBack(mCallBack);      } catch (RemoteException e) {        e.printStackTrace();      }    }    unbindService(connection);  }  @Click(R.id.btn_connect)  void connectClick()  {    TraceLog.i();    bindSamplesService();  }  @Click(R.id.btn_unconnect)  void unConnectClick()  {    TraceLog.i();    unBindSamplesService();  }  @Click(R.id.btn_do)  void doAction()  {    if(binder!=null)    {      try {        int r = binder.doBackground("action");        TraceLog.i(String.valueOf(r));      } catch (RemoteException e) {        e.printStackTrace();      }    }  }  @Override  protected void onDestroy() {    super.onDestroy();    TraceLog.i();    unBindSamplesService();  }}
