Android 8，程序员必学之一

void bindSuccess();

void unbind();

}

注意两个应用的 AIDL 文件必须一致，包括包名。

然后，编写两个 binder 实体服务 RemoteService 、LocalService，主要代码如下：

public class RemoteService extends Service {

private static final String TAG = “RemoteService”;

@Override
public void onCreate() {
super.onCreate();
Log.e(TAG, “onCreate: 创建 RemoteService”);
bindLocalService();
}

@Override
public IBinder onBind(Intent intent) {
return stub;
}

private IMyAidlInterface.Stub stub = new IMyAidlInterface.Stub() {
@Override
public void bindSuccess

() throws remoteexception {
Log.e(TAG, “bindSuccess: LocalService 绑定 RemoteService 成功”);
}

@Override
public void unbind() throws remoteexception {
Log.e(TAG, “unbind: 此处解除 RemoteService 与 LocalService 的绑定”);
getApplicationContext().unbindService(connection);
}
};

/**

• 绑定 LocalService
  */
  private void bindLocalService() {
  Intent intent = new Intent();
  intent.setComponent(new ComponentName(“com.wuzy.aidlclient”, “com.wuzy.aidlclient.LocalService”));
  if (!getApplicationContext().bindService(intent, connection, Context.BIND_AUTO_CREATE)) {
  Log.e(TAG, “bindLocalService: 绑定 LocalService 失败”);
  stopSelf();
  }
  }

private ServiceConnection connection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {

}

@Override
public void onServicedisconnected(ComponentName name) {
// bindRemoteService();
createTransferActivity();
}
};

private void createTransferActivity() {
Intent intent = new Intent(this, TransferActivity.class);
intent.setAction(TransferActivity.ACTION_FROM_SELF);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}

public class LocalService extends Service {

private static final String TAG = “LocalService”;

@Override
public void onCreate() {
super.onCreate();
Log.e(TAG, “onCreate: 创建 LocalService”);
bindRemoteService();

}

@Override
public IBinder onBind(Intent intent) {
Log.e(TAG, “onBind: 绑定 LocalService”);
return stub;
}

private IMyAidlInterface.Stub stub = new IMyAidlInterface.Stub() {
@Override
public void bindSuccess() throws remoteexception {
Log.e(TAG, “bindSuccess: RemoteService 绑定 LocalService 成功”);
}

@Override
