Camera preview failed

[Zookey]

I tried to use this library on Samsung Galaxy S5 with Andorid 6.0.1 and I get following error:

java.lang.RuntimeException: startPreview failed at android.hardware.Camera.startPreview(Native Method) at info.androidhive.barcode.camera.CameraSource.start(CameraSource.java:380) at info.androidhive.barcode.camera.CameraSourcePreview.startIfReady(CameraSourcePreview.java:91) at info.androidhive.barcode.camera.CameraSourcePreview.access$200(CameraSourcePreview.java:33) at info.androidhive.barcode.camera.CameraSourcePreview$SurfaceCallback.surfaceCreated(CameraSourcePreview.java:114) at android.view.SurfaceView.updateWindow(SurfaceView.java:712) at android.view.SurfaceView$3.onPreDraw(SurfaceView.java:209) at android.view.ViewTreeObserver.dispatchOnPreDraw(ViewTreeObserver.java:1014) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:2510) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1437) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:7397) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:920) at android.view.Choreographer.doCallbacks(Choreographer.java:695) at android.view.Choreographer.doFrame(Choreographer.java:631) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:906) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:158) at android.app.ActivityThread.main(ActivityThread.java:7224) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1230) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1120)
