How to migrate an old Android Studio project in Gradle

05 Jul 2015

The most common issue that affects users is the runProguard property changing names to minifyEnabled. If you run into the build error

Gradle DSL method not found: ‘runProguard()’

then this is the cause of your build error.

This crops up a lot because that property was inserted into all projects created by Android Studio prior to version 0.14.0.

To update your project, edit your build.gradle file as follows:

    release {
-       runProguard true
+       minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
