问题
I am trying to build a solution in Xamarin with an android library that I imported.
The library come from a manufacturer called bbpos.
I have the following error message :
Error com.android.dx.cf.code.SimException: local variable type mismatch: attempt to set or access a value of type java.lang.String using a local variable of type byte[]. This is symptomatic of .class transformation tools that ignore local variable information.
I think it comes from the library but i dont know from where exactly. Is there a way to know where is the problem ?
回答1:
In case it my help someone else i have finally found the solution.
It turns out the compiler was the problem.
I went to the Xamarin.Android Properties, then went to the Android Options tab. In the Dex compiler field I selected d8.

It's quite likely that the library you received isn't built correctly. If you remove the library and the build goes through normally, the problem is definitely there. The thing is, I haven't seen this problem in years and it's quite surprising to see now.
Just to be sure, are you talking about a jar library, not a dll? The (likely) root cause of the problem is explained well in other posts here and here. What you should do to resolve your issue is to try two things:
- Build your application with ProGuard enabled.
- If that doesn't work, run the library itself through ProGuard as suggested by one of the posts I linked to.
