Error compiling Android app with Material Components and androidX

Question

Android application suddenly refuses to build, it returns this error:

Android resource linking failed error: resource style/Theme.MaterialComponents.Light.NoActionBar (aka it.duemilanet.icircle:style/Theme.MaterialComponents.Light.NoActionBar) not found.

D:\GitLab\iCircleAndroidRMA\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:1440: error: style attribute 'attr/colorSecondary (aka it.duemilanet.icircle:attr/colorSecondary)' not found. error: resource style/Widget.Design.BottomSheet.Modal (aka it.duemilanet.icircle:style/Widget.Design.BottomSheet.Modal) not found. error: resource style/Theme.Design.Light.BottomSheetDialog (aka it.duemilanet.icircle:style/Theme.Design.Light.BottomSheetDialog) not found. D:\GitLab\iCircleAndroidRMA\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:3296: error: style attribute 'attr/bottomSheetStyle (aka it.duemilanet.icircle:attr/bottomSheetStyle)' not found. error: failed linking references.

It was compiling just fine before, i switched to androidX and material components theme weeks ago and enabled jetifier without problems

• I tried to disable Instant Run and to revert to previous versions of the material library but i couldn't fix the error.

Answer 1

There are several components which are referenced in the material design documentation which aren't yet in a stable release of the material design library for Android. Try using the alpha version instead.

Add the following to your build.gradle:

dependencies { 
    ...
    implementation 'com.google.android.material:material:1.2.0-alpha02'
}
