appcompat_v7 error ubuntu - BONGDATV

implementation 'com.android.support:appcompat-v7:24.2.1' is very old but it exists. Check in your top-level build.gradle the repositories block. You have to add the google() repo. allprojects { repositories { google() jcenter() } } In any case consider to: use the last release of Support Library 28.0.0 instead of 24.2.1

I was just digging through my folders and saw the same thing. Files in sdk/extras/android/m2repository/…/appcompat-v7 haven't been updated since November 2017. I'm thinking these are leftovers and Android Studio and Gradle manage those differently now. Trying to figure this out too…

I just installed Android Studio on elementary os 0.3.1 (based on Ubuntu 14.04 LTS), but I get the following error: Error:(24, 13) Failed to resolve: com.android.support:appcompat-v7:15.+ Install

Solved error with AppCompat 27 - Advanced - Android IDE (AIDE) Support Forum. Advanced. dekubi April 2, 2019, 1:46pm #1. Open your project. Navigate to the first build.gradle file in your app structure. Add "mavenCentral ()" to your repositories. Now add AppCompat library to you project and your app will compile and run successfully.
