Edit: if the targetSDK is greater than 10, putting the app to sleep calls onPause and onStop. Source I looked at the lifecycle of both the Activity and the SurfaceView in a tiny camera app on my gingerbread phone. You are entirely correct; the surface is not destroyed when the power button is pressed to … Read more
Here is the approach we ended up using: if ([AVCaptureDevice respondsToSelector:@selector(requestAccessForMediaType: completionHandler:)]) { [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) { // Will get here on both iOS 7 & 8 even though camera permissions weren’t required // until iOS 8. So for iOS 7 permission will always be granted. if (granted) { // Permission has been granted. … Read more
In your AVD advanced settings, you should be able to set front and back cameras to Webcam() or Emulated.
private Camera openFrontFacingCameraGingerbread() { int cameraCount = 0; Camera cam = null; Camera.CameraInfo cameraInfo = new Camera.CameraInfo(); cameraCount = Camera.getNumberOfCameras(); for (int camIdx = 0; camIdx < cameraCount; camIdx++) { Camera.getCameraInfo(camIdx, cameraInfo); if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) { try { cam = Camera.open(camIdx); } catch (RuntimeException e) { Log.e(TAG, “Camera failed to open: ” + e.getLocalizedMessage()); … Read more
From other member and my problem: Camera Rotation issue depend on different Devices and certain Version. Version 1.6: to fix the Rotation Issue, and it is good for most of devices if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) { p.set(“orientation”, “portrait”); p.set(“rotation”,90); } if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) { p.set(“orientation”, “landscape”); p.set(“rotation”, 90); } Version 2.1: depend on kind … Read more
I used this code once to capture iOS default shutter sound (here is list of sound file names https://github.com/TUNER88/iOSSystemSoundsLibrary): NSString *path = @”/System/Library/Audio/UISounds/photoShutter.caf”; NSString *docs = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]; NSData *data = [NSData dataWithContentsOfFile:path]; [data writeToFile:[docs stringByAppendingPathComponent:@”photoShutter.caf”] atomically:YES]; Then I used third-party app to extract photoShutter.caf from Documents directory (DiskAid for Mac). Next step … Read more
The problem in iOS7 has to do with transitions. It seems that if a previous transition didn’t complete and you launch a new one, iOS7 messes the views, where iOS6 seems to manage it correctly. You should initialize your Camera in your UIViewController, only after the view has Loaded and with a timeout: – (void)viewDidAppear:(BOOL)animated … Read more
Not all parameters are supported by all cameras – actually, they are one of the most troublesome part of the OpenCV library. Each camera type – from android cameras to USB cameras to professional ones offer a different interface to modify its parameters. There are many branches in OpenCV code to support as many of … Read more
This issue appeared to start out as a bug with certain hardware see here but can be overcome by using the call to mCamera.setDisplayOrientation(degrees) available in API 8. So this is how I implement it: public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { if (isPreviewRunning) { mCamera.stopPreview(); } Parameters parameters = mCamera.getParameters(); … Read more
We have quite similar problem. So far the only workaround we were able to do is to remove the meta tag for it to be “apple-mobile-web-app-capable” and let users to open it in Safari, where everything seems to work normally.
