Fail to connect to camera service #358

Closed ckenergy closed 5 years ago

ckenergy commented 6 years ago

Description of the problem:

in ScannerActivity start a NewActivity, in NewActivity onResume use camera = Camera.open(); got Fail to connect to camera service error; i think in CameraInstance.close() method use cameraThread.enqueue(closer) is delay NewActivity.onResume() , so i call Camera.open() the camera is not release; when i use closer.run() instead cameraThread.enqueue(closer), it work

Which library version are you using? E.g. 3.2.0. 3.5.0 Which phone/tablet are you using, and which Android version does it run? (e.g. Samsung Galaxy S5, Android 5.0) android 4.4

Started the scanner via:

 if (getApplicationContext().getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA)) {

            IntentIntegrator integrator = new IntentIntegrator(this);
            integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
            integrator.setPrompt("USE VOLUME KEYS FOR FLASHLIGHT");
            integrator.setCameraId(0);  // Use a specific camera of the device
            integrator.setBeepEnabled(true);
            integrator.setBarcodeImageEnabled(true);
            integrator.initiateScan();

        }

Additionally this will pop up too:

For the original issue: By design, the camera management is performed in a background thread, so the camera may still be in use by the time the Activity is closed.

I recommend retrying opening the camera for a second if two.

For the other comments, please open a new issue if you still have trouble with the latest version.
