Answer 1

It's the bug in https://services.gradle.org/distributions/gradle-4.10.1-all.zip .

You need to roll back to https://services.gradle.org/distributions/gradle-4.6-all.zip in gradle-wrapper.properties

And

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1' //roll back to this version

I have deal with this bug for 4 hours. I gave up so I rolled back to last version. It's perfect now. So let's wait for the newer version. Don't upgrade, yet!

Answer 2

run a gradle task with this flag -Pandroid.debug.obsoleteApi=true and it will let you know where the obsolete feature is being used.

After identifying where the issue is, you can try updating as the message suggests

ex. .gradlew app:assembleDebug -Pandroid.debug.obsoleteApi=true
