`

I read over the problem, and this is because the lib zxing:core use Java 8 and this is not support in api < 24. The solution is compiler zxing:core version 3.3.3.

It's possible?

or exist other implementation?

Thank you.

or which version of this lib use zxing:core 3.3.3?

Hey,

we are also facing this problem.

this is caused by this issue zxing/zxing#1170
Problem starts with version 3.4.0+

But this library ist using 3.3.3
So the Problem should not happen.

Did i miss something ?
