Maybe same problem.
I got the bug report from Crashlytics at Nov 17 2017 18:36 (UTC).
I'm not sure it was caused by the library or a mistake in my code.

Description of the problem:

Which library version are you using? 3.5.0.

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

Galaxy A8 - Android 6.0.1

Does the same happen on other devices or an emulator? No

Can you reproduce the issue in the sample project included with the library? If not, can you
provide your own sample project or sample code that produces this error? No

In the case of an error do you have a stack trace or adb logs?

Same issue here. Are you accepting pull requests?

[soenkegissel]

same here.

[AlCabohne]

Here as well, any news on this issue?

[kevag]

We are facing exactly the same bug at random times with Samsung Galaxy S8 Plus(Android version : 8.0.0) and Samsung Galaxy J7 Prime(Android version : 8.1.0) phones.
Is there any update on this issue?

BRS / Kostas

[ljfantin]

Any news about this issue ?

[Cylix]

Any plan to merge these fixes? Is this library still maintained?

[rkistner]

Should be fixed in v4.0.2.

[FrantisekGazo]

@rkistner can you please add a fix to 3.x version as well?

I'm asking cause our app needs to support android api 21 so we cannot upgrade to 4.x version

[FrantisekGazo]

Can you please answer?
If you plan to completely abandon lower android api then 24 could you at least write how you fixed it so maybe I could fork your repo and fix it there at least?

[rkistner]

The fixes won't be backported.

You can use the latest versions with Android API 14+, either by:

1. Downgrading zxing:core - see https://github.com/journeyapps/zxing-android-embedded#older-sdk-versions
2. OR by using AGP - see Correct minSdkVersion to 19 #612
