回答1:

if you have : "_internal_aapt2_binary" in gradle file (for earlier versions of gradle) then just remove that.

configurations.matching { it.name == '_internal_aapt2_binary' }.all { config ->
    config.resolutionStrategy.eachDependency { details ->
        details.useVersion("3.5.0-alpha03-5252756")
    }
}

There was some issue with proguard rules, in some rules there were some extra space and in other rules, i just have to delete them and re-write them manually instead of copy-paste from web page.

Strange issue, took a lot of time to identify such silly issues, @android should do something about such proguard issues, at least spaces at the end could be trimmed automatically.
