flashlight

The use of front light option with zxing1.6 barcode scanner does not work on my Nexus One. I need to be able to use the flashlight in my app, but you can't have two instances of the camera running. Is there a way to use the flashlight without accessing the camera? Or can I somehow access a camera that is already in use? I am using the Google IntentIntegrator.java patch to be able to scan barcodes. The short answer is "no"; the front LED is controlled as a flash mode, which is a property of the camera. It is mode "torch". And no two apps can't open the camera at the same time. (A longer answer

My app turn on camera LED using FLASH_MODE_TORCH , but now some people say that FLASH_MODE_TORCH will not work on some Samsung devices correctly. So should I use FLASH_MODE_ON for all devices to work?(especially for Samsung devices) may be this will help you Parameters params = null; if(mCamera != null) { params = mCamera.getParameters(); if(params != null) { List<String> supportedFlashModes = params.getSupportedFlashModes(); if(supportedFlashModes != null) { if(supportedFlashModes.contains(Parameters.FLASH_MODE_TORCH)) { params.setFlashMode( Parameters.FLASH_MODE_TORCH ); } else if

I'm building an iOS app in Swift with a Firebase backend. I need advanced search options for my app. I've been told I should use Flashlight/ElasticSearch via this github link https://github.com/firebase/flashlight Assume my app's name is SneakerSearch and my Firebase Project_ID is- sneakersearch-az12 Firebase Web_API_Key is- abc123XYZ000... Firebase App_Url is- gs://sneakersearch-az12.appspot.com I need some advice with the steps for setting this up as I'm new to Heroku and Node.js. I never learned either before but I've already installed the Heroku tool belt and 'sudo gem heroku install' is

I've got the following problem: My Flashlight app works fine on my Samsung Galaxy S2 but unfortunately not on the Samsung Galaxy Nexus (problem: flashlight ignores the button-click -> no reaction, no light, no crash, no exception). I've read "LED flashlight on Galaxy Nexus controllable by what API?" here in stackoverflow but it did not help me since my problem still occures. This is my code-snippet to control the light: final Button FlashLightControl = (Button)findViewById(R.id.ledbutton); FlashLightControl.setOnClickListener(new Button.OnClickListener() { public void onClick(View arg) { if

I am writing an Android Camera App and trying to implement Flash functionality, I am using SurfaceView, whenever i do tap on flash button toggle works but flash not coming... see my below code i have used to Turn ON/OFF Flashlights. Complete code:-- @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_camera); preview=(SurfaceView)findViewById(R.id.surface); previewHolder=preview.getHolder(); previewHolder.addCallback(surfaceCallback); previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); previewHolder

since i'm at the beginning with Android coding i hesitated to post my question, but now i'm at the point where i can't resist. I have a service which turns on the camera-LED onCreate: @Override public void onCreate() { // make sure we don't sleep this.pm = (PowerManager) getSystemService(Context.POWER_SERVICE); this.mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "SleepLED"); this.mTimer = new Timer(); this.mTimerTask = new TimerTask() { public void run() { // turn on the LED setFlashlight(Camera.Parameters.FLASH_MODE_TORCH); mWakeLock.acquire(); } }; // Get the notification-service

I'd like to add flashlight functionality to my app in Swift. How can I go about doing that? Lyndsey Scott Update #1: ( torchActive isn't returning the expected value; perhaps because it's been modified ) Update #2: For Swift 2.0 To toggle the flash from on to off (not just "on" as in mad pig's answer), you can use the following method: func toggleFlash() { let device = AVCaptureDevice.defaultDeviceWithMediaType(AVMediaTypeVideo) if (device.hasTorch) { do { try device.lockForConfiguration() if (device.torchMode == AVCaptureTorchMode.On) { device.torchMode = AVCaptureTorchMode.Off } else { do {
