跨应用绑定Service

Android使用AIDL（Android接口定义语言）来进行应用之间通信。
首先需要新建一个AIDL文件，在App中（需要注意的是添加之后需要先Rebuild一下才能开始使用这个类）。
之后再AppService中的onBinder方法中使用这个AIDL：
public class AppService extends Service {
public AppService() {
}

@Overridepublic IBinder onBind(Intent intent) {       return new IAppServiceRemoteBindler.Stub() {        @Override        public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) throws RemoteException {        }    };}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {    return super.onStartCommand(intent, flags, startId);}@Overridepublic void onCreate() {    super.onCreate();    System.out.println("Service start");    new Thread(){        @Override        public void run() {            super.run();            running = true;            while (running){                System.out.println(data);                try {                    Thread.sleep(1000);                } catch (InterruptedException e) {                    e.printStackTrace();                }            }        }    }.start();}@Overridepublic void onDestroy() {    super.onDestroy();    System.out.println("service destroyed");    running = false;}private String data = "默认数据";private boolean running = false;

}
之后需要在AnotherApp中绑定App中的服务：
public class MainActivity extends AppCompatActivity implements View.OnClickListener, ServiceConnection {

private Intent serviceIntent;private EditText etInput;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    serviceIntent = new Intent();    serviceIntent.setComponent(new ComponentName("com.chenshipeng.startservicefromanotherapp","com.chenshipeng.startservicefromanotherapp.AppService"));    etInput = (EditText)findViewById(R.id.etInput);    findViewById(R.id.btnStartAppService).setOnClickListener(this);    findViewById(R.id.btnStopAppService).setOnClickListener(this);    findViewById(R.id.bindAppService).setOnClickListener(this);    findViewById(R.id.unBindAppService).setOnClickListener(this);    findViewById(R.id.btnSync).setOnClickListener(this);}@Overridepublic void onClick(View v) {    switch (v.getId()){        case R.id.btnStartAppService:            startService(serviceIntent);            break;        case R.id.btnStopAppService:            stopService(serviceIntent);            break;        case R.id.bindAppService:            bindService(serviceIntent,this, Context.BIND_AUTO_CREATE);            break;        case R.id.unBindAppService:            unbindService(this);            bindler = null;            break;           }}@Overridepublic void onServiceConnected(ComponentName name, IBinder service) {    System.out.println("bind service");    System.out.println(service);}@Overridepublic void onServiceDisconnected(ComponentName name) {}

}
