Answer 1

In gradle.properties change android.enableAapt2=false to true

Answer 2

You can actually have problems in the resources but these will not be displayed if you do not correct this problem first:

The option 'android.enableAapt2' is deprecated and should not be used anymore. Use 'android.enableAapt2 = true' to remove this warning. It will be removed at the end of 2018.

within your gradle.properties file that is located in the root of the project, replace:

android.enableAapt2 

with:

android.enableAapt2 = true
