Android bindservice绑定服务，并同步返回service对象的两个方法-CSDN博客

补充反射并调用bindServiceAsUser的方法：

private boolean initService2(final Context context){
        if(deviceService==null){
            latch = new CountDownLatch(1);
            HandlerThread handlerthread = new HandlerThread("bindservice_thread");
            handlerthread.start();
            final Handler handler = new Handler(handlerthread.getLooper());
            handler.post(new Runnable() {
                @Override
                public void run() {
                    try {
                        mConn=new ServiceConnection() {
                            @Override
                            public void onServiceConnected(ComponentName className, IBinder
                                    iBinder) {
                                deviceService = IDeviceService.Stub.asInterface(iBinder);
                                isBind[0] =true;
                                latch.countDown();
                            }
                            @Override
