title: Android buildscript repositories: jcenter VS mavencentral
body: <p>The last time I used Android Studio, it generated <code>.gradle</code> files with <code>mavencentral()</code> buildscript repositories whereas now there's <code>jcenter()</code>. </p>
  
  <p>Could anyone explain the issues connected with this. Are there any other repos? When should we switch them? What impact do they have on projects, modules, libs? Any other essentials for Android developers?</p>
  
  <p>Who's responsible for maintaining those repos?</p>
