android Aidl 实现进程间通讯

1，android 新建aidl 文件删除void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString);这个方法没用到还需要实现。

2，添加自己需要的方法例如

package com.cglt.cutticket;// Declare any non-default types here with import statementsinterface CgltechAidl {     int getApkVersionCode();}

3，定义Service，定内部类CgltehcBinder 实现Aidl接口，并且onBind返回实现类

public class AidlService extends Service {    class CgltehcBinder extends CgltechAidl.Stub {        public CgltehcBinder() {            Log.e("biner", "biner");        }        @Override        public int getApkVersionCode() throws RemoteException {            return AppInfo.apkVerisonCode;        }    }    @Nullable    @Override    public IBinder onBind(Intent intent) {        return new CgltehcBinder();    }}

4，配置Service，action为CgltechAidlAction

5，另一个apk绑定这个service

Intent intent = new Intent();intent.setAction("CgltechAidlAction");//Service的actionintent.setPackage("com.cglt.cutticket");//Service 所在包名bindService(intent, new ServiceConnection() {    @Override    public void onServiceConnected(ComponentName name, IBinder service) {        Log.e("fff","ok");        cgltechAidl = CgltechAidl.Stub.asInterface(service);        try {            Log.e("fff",cgltechAidl.getApkVersionCode()+"/");        } catch (RemoteException e) {            e.printStackTrace();        }    }    @Override    public void onServiceDisconnected(ComponentName name) {        Log.e("fff","no");    }}, BIND_AUTO_CREATE);
