Answer 1

I was facing the same issue, is related to the 64k limit "multidex".

I was using multiDexEnabled true property in build.gradle in defaultConfig block, under android one.

As stated in Google documentation

for devices with Android API prior to 21, we need to include the multidex library (implementation 'com.android.support:multidex:1.0.2')

and extend MultiDexApplication in our Application class
