I'm learning developing app for android. In particular, how it works a mediaplayer. The target system should be android for automotive. For this reason I have downloaded a sample UAMP application from google but, unfortunately, doesn't compile, it is too old. So I decided to rebuild a project and importe all the modules. For me is important understand how it works! Anyway, I have imported all libraries, in gradle and in the modules, I have compiled the automotive version of the app and I have this message:
*The given artifact contains a string literal with a package reference 'android.support.v4' that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx*.In detail, the gradle explains:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':automotive:mergeDebugJavaResource'.
Could not resolve all files for configuration ':automotive:debugRuntimeClasspath'.

This is a known exception, and Jetifier won't be able to jetify this library.
>Ok, sorry for my poor english, but the problem is quite complex and my english is not so advanced. The project for automotive is composed by three branches, the mobile app, the automotive app and a shared branch. Now I am working on the automotive branch, and its includes the shared branch. The first thing I did was check if may be one or more included libraries were not the last release. And as I can understand all the libraries are the last version and compatible with androidx (my target system) here the list of include libraries on the Automotive branch:
>
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation "org.jetbrains.kotlin:kotlin-stdlib:1.3.72"
implementation "androidx.core:core-ktx:1.2.0"

}In the shared branch the included libraries are:

implementation 'androidx.media:media:1.1.0'

// in the individual module build.gradle files

}So, I have tryed any thing I know, but the issue is still there. Is there anyone, that can give me a suggestion, an Idea, something that can help me to solve this problem and proceed on the training? Thanks a lot for any contribute.
