Answer 1

Reason of the issue is in the showHelpOnFirstLaunch() method in CaptureActivity. It tries to get version of com.google.zxing.client.android package, doesn’t find it and throws the exception. It must be catched by catch (PackageManager.NameNotFoundException e) { ... }. I don’t know why exception is not catched.

You can edit showHelpOnFirstLaunch() method, e.g. remove the checking of package version or add exception catching if you haven’t it in your version.
