Android studio - App with library project fails to build

Question

I\'m having massive trouble trying to get my app project to build. I have the main app module and a library project module as shown below:

Answer 1

Just explicitly tells gradle that your library project must not being minified by adding/modifying section

android/buildTypes/debug

of your library project's build.gradle file like this (minifyEnabled false is the key):

android {
...
    buildTypes {
        debug {
            debuggable true
            minifyEnabled false
        }
...
    }
...
}

Note:

Here, I also instruct explicitly gradle to make my 'debug' build debuggable (debuggable true).
