Error Java.lang.nosuchmethoderror: No Static Method

I'm trying to run code from git link below https://github.com/Mikhail57/RetrofitTutorial But i get an error java.lang.NoSuchMethodError: No static method getFont(Landroid/content/

Solution 1:

Use this

compileSdkVersion 27.0.2
buildToolsVersion '27.0.2'
implementation 'com.android.support:appcompat-v7:27.0.2'

Instead of this

compileSdkVersion 26
implementation 'com.android.support:appcompat-v7:26.1.0'
