Ionic 3 Android Build Error (could not find support-v4.jar)

Question

I have an Ionic 3 app that has built fine on dev machines for quite a while. Today we tried a new machine and it doesn\'t build there. It is using an older cordova-android

Answer 1

You have to do some modifications in your build.gradle file inside platforms/android as follows:

allprojects { 
  repositories { 
    mavenCentral()
    maven { url 'https://maven.google.com' } //add this code
    jcenter() 
 } 
}

It's essential for new versions of google libraries. They moved their libraries out of the android SDK to the maven repo.
