Question

我试图在背景中重新播放30秒的许多视频，但在20或30个视频后，我的服务正在停止并启动录制过程缓慢进行。

我在同一个过程中尝试使用服务，但问题是一样的。

我的视频处理程序：

@Override
public void onCreate() {
    super.onCreate();
    isRunning = true;
    idAlerta = Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "");
    videoCount = 1;
    mIntentRecorder = new Intent(VideoHandlerService.this, RecorderService.class);
    mIntentSend = new Intent(VideoHandlerService.this, SendVideoService.class);
    updateVideoTime();
    mIntentRecorder.putExtra(Constants.VIDEO_TIME, videoTime);
    mIntentRecorder.putExtra(Constants.ID_ALERTA_SERVICE, idAlerta);
    mIntentRecorder.putExtra(Constants.COUNT_ALERTA, videoCount);
    startService(mIntentRecorder);
    newVideo();
}
public void newVideo() {
    Common.log("new Video");
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            videoCount++;
            startNewVideo();
            if (videoCount == 2)
                sendVideo(4000);
        }
    }, videoTime + 2000);

}


public void startNewVideo() {
    final Intent intentRecorder = new Intent(VideoHandlerService.this, RecorderService.class);
    intentRecorder.putExtra(Constants.VIDEO_TIME, videoTime);
    Common.log("idAlerta " + idAlerta);
    intentRecorder.putExtra(Constants.ID_ALERTA_SERVICE, idAlerta);
    intentRecorder.putExtra(Constants.COUNT_ALERTA, videoCount);
    stopService(intentRecorder);
    if (Common.getStorage().getBoolean(Constants.RECORDER_ACTIVE, false)) {
        if (Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "") != null && Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "").length() > 0) {

            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    Common.log("Start service recorder");
                    startService(intentRecorder);
                    newVideo();
                }
            }, 5000);
        }
    } else
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                startNewVideo();
            }
        }, 5000);
}

这是记录的过程：

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Common.log("onStartCommand");
    if (intent != null && ((Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "") != null && Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "").length() > 0))) {
        windowManager = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
        mLayoutParams = new WindowManager.LayoutParams(
                1, 1,
                WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
                WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
                PixelFormat.TRANSLUCENT
        );
        mLayoutParams.gravity = Gravity.LEFT | Gravity.TOP;
        //Cojo Información del videohandler
        Common.log("Intent distinto de null");
        mVideoTime = intent.getIntExtra(Constants.VIDEO_TIME, 15000);
        mIdAlerta = intent.getStringExtra(Constants.ID_ALERTA_SERVICE);
        mVideoCount = intent.getIntExtra(Constants.COUNT_ALERTA, 1);
        Common.log("Video time" + mVideoTime);
        Common.getStorage().putBoolean(Constants.RECORDER_ACTIVE, true);
        initRecording();
    }
    return START_NOT_STICKY;
}

public void initRecording() {
    Common.log("INIT RECORDING IN");
    surfaceView = new SurfaceView(this);
    windowManager.addView(surfaceView, mLayoutParams);
    surfaceView.getHolder().addCallback(this);
    Common.log("INIT RECORDING OUT");
}

当我尝试停止服务时，服务停止，但即使杀死应用程序，相机也不会被释放。有人能帮我吗？？提前谢谢。

Answer 1

在服务的onDestroy（）方法中，将camera.lock()替换为camera.unLock()，并在startRecorder（）方法中将camera.unLock()替换为camera.lock()

Answer 2

最后，密钥是使用PowerManager，如果要使用它，别忘了释放它！

private fun lock() {
    log("lock")
    var powerManager: PowerManager = getSystemService(Context.POWER_SERVICE) as PowerManager
    powerWakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK or PowerManager.ACQUIRE_CAUSES_WAKEUP, "WakeLock-Manager")
    powerWakeLock.acquire()

    var wifiManger: WifiManager = applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
    wifiWakeLock = wifiManger.createWifiLock(WifiManager.WIFI_MODE_FULL_HIGH_PERF, "WifiLock-Manger")
    wifiWakeLock.acquire()
    log("lock")
}
