Library can not use R?

[WayLoCode]

java.lang.NoClassDefFoundError: Failed resolution of: Lme/vigi/fataar/demo/aarLib/R$layout;
at me.vigi.fataar.demo.aarLib.AarLibActivity.onCreate(AarLibActivity.java:17)

This plugin just copy library's jar to libs dir and merge asset、res etc；So the aarLib's R.java is not generated，then your error coming

[rusmichal]

Did you find workaround? @WayLoCode

[nikgupta1231]

@WayLoCode did you find any solution for this?

I got the same issue. Have you found any solutions? friend

[songnick]

there is no solution for this problem, because the gradle plugin merge the resource and generate the R.java, so we can not resolve this problem

[richfuns]

Any workaround??

there is no solution for this problem, because the gradle plugin merge the resource and generate the R.java, so we can not resolve this problem

we can fix this problem by two ways:

1. after merge resources, we create R.java by R.txt file, then merge all R.java to libs folder as a normal jar file;
2. after merge classes.jar, we transform class file, replacing R.java to main module's package name, eg:
   module A's package name: com.example.a
   module B's package name: com.example.b
   main module merge module A and module B, which package is : com.example.main.
   Then all we have to do is replacing all java file's import R.java statement from

import com.example.a.R.layout;
import com.example.a.R.drawable;

to

import com.example.main.R.layout;
import com.example.main.R.drawable;

etc.

The second way is recommended, because it won't increase aar's file size.
