我们的项目中有时候会出现开启多个进程的情况每个进程中会有不同的逻辑,加入我们有10中逻辑就要有10个service么这种肯定不可取的,这样会浪费我们内存资源,下面介绍就是如何在一个service 中 进行多个aidl操作 直接上代码 关键代码主要在BinderPoor类中,因为我们在BinderPoor类 使用了CountDownLatch所用我们要在Activity开启线程执行 //CountDownLatch起到了同步的作用 @Route(path = MyTaskArouterConsts.Data) public class BindActivitys extends Activity { @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); new Thread(new ServiceWorks()).start();
}private IComput computs; private void doWork() { BinderPoor binderPoor = BinderPoor.getInsance(this); IBinder binder = binderPoor.queryBinders(2); computs = (IComput) Computs.asInterface(binder); try { int all = computs.add(10, 10); System.out.println(all + “总数”); } catch (RemoteException e) { e.printStackTrace(); }
}private class ServiceWorks implements Runnable{
@Override public void run() { doWork(); }}
}
/**
关键的辅助类 */ public class BinderPoor { public static final int BINDER_NONE = -1; public static final int BINDER_COMPITE = 0; public static final int BINDER_CEBTER = 1;

ServiceConnection serviceConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { mIBinderPoor = IBinderPoor.Stub.asInterface(service); try { mIBinderPoor.asBinder().linkToDeath(mBindDeathRecipient, 0); downLatch.countDown(); } catch (RemoteException e) { e.printStackTrace(); } }
