# compose

I have a KMP library, string resources are defined in the commonMain/composeResources. The androidMain source set accesses the resources using the Res API of CMP. Sample app in the project works fine, but when I publish the library, and use it a different app, I get a crash because resources couldn't be found. Is this a known thing? If yes, how does the current libraries handle this?

This is what I got during my research:

CMP resources work in published libraries. The issue is that the .cvr files need to be bundled in the AAR's assets/ directory

Ok. Looks like, the crash is still happening in local build and not just in published AAR.
However, adding this flag, fixes this.

experimentalProperties["android.experimental.kmp.enableAndroidResources"] = true
