android aidl进程间方法的调用

android 进程的通信很多，可以用intent传递数据，可以实现数据的共享，可以通过aidl实现进程间的通信，一般如果进程间需求方法调用的时候就要实现aidl
这个说明一下aidl进程间的对象的传递。
我们先是申明一个aidl的接口的文件IWorkFlowPlugin.aidl在里面实现一个对象传递的方法，
interface IWorkFlowPlugin
{
   WorkFlowBean getWorkFlowBean();
}
声明一个WorkFlowBean的java的文件，实现Parcelable接口
public class WorkFlowBean implements Parcelable
{

    /**
     * Parcelable
     */
    public static final Parcelable.Creator<WorkFlowBean> CREATOR = new Creator<WorkFlowBean>()
    {

        @Override
        public WorkFlowBean createFromParcel(Parcel source)
        {
            WorkFlowBean workFlowBean = new WorkFlowBean();
//            workFlowBean.ecsSDK = (EcsSDKImpl)source.readSerializable();
            workFlowBean.ecsSDK = EcsSDKImpl.getInstance();
            return workFlowBean;
        }

        @Override
        public WorkFlowBean[] newArray(int size)
        {
            return new WorkFlowBean[size];
        }
    };
   
    private EcsSDKImpl ecsSDK;
   
    @Override
    public int describeContents()
    {
        return 0;
    }

    public EcsSDKImpl getEcsSDK()
    {
        return ecsSDK;
    }
   
    @Override
    public void writeToParcel(Parcel dest, int flags)
    {
//        dest.writeSerializable(EcsSDKImpl.getInstance());
    }

如果想实现对象的传递的时候，必须声明一个新的aidl文件和javaBean的类名一致的
WorkFlowBean.aidl 里面书写 parcelable WorkFlowBean;
实现一个service
public class WorkFlowService extends Service
{
   
    private class WorkFlowServiceImpl  extends IWorkFlowPlugin.Stub
    {
        @Override
        public WorkFlowBean getWorkFlowBean()
            throws RemoteException
        {
            return WorkFlowBean.CREATOR.createFromParcel(null);
        }
    }
   
    @Override
    public IBinder onBind(Intent intent)
    {
        return new WorkFlowServiceImpl();
    }
   
}

在其它的进程中实现一个ServiceConnection的连接类
private class MyServiceConnection implements ServiceConnection
    {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service)
        {
            workFlowPlugin = IWorkFlowPlugin.Stub.asInterface(service);
        }

        @Override
        public void onServiceDisconnected(ComponentName name)
        {
           
        }
       
    }
