Failed resolution of: Landroid/support/v7/appcompat/R$drawable;

Question

I tried to update some modules on a project that I hadn't run for about a month. Now I can't figure out how to get rid of this 'java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/appcompat/R$drawable;' error.

I've tried removing and replacing appcompat-v7. I've tried clean->rebuild.

Anyone have any ideas?

build.gradle

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'realm-android'

Answer 1

I finally solved this after finding this https://github.com/realm/realm-java/issues/6557

My solution was to update Realm by changing a line in my project level build.gradle

from classpath 'io.realm:realm-gradle-plugin:5.7.0' to classpath 'io.realm:realm-gradle-plugin:6.0.2'

and clean->rebuilding the project.

I also wiped my emulated device.

I don't fully understand what caused this, but it seems that there was some chnge to that realm-gradle-plugin that caused it not to handle some view dependencies correctly.
