Answer 1

All of these solutions did not work for me on Android Studio 2.1. What worked was me opening gradle-wrapper.properties in project folder and changing my gradle reference on the line below:

distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip

This was changed to:

distributionUrl=https\://services.gradle.org/distributions/gradle-2.13-all.zip

After which gradle upgraded and the app started working!
