Ever feel like all you do is waiting for the builds to complete in Android Studio all day? Me too. Fortunately, there are a number of improvements you can do to speed things up. Some of these are still experimental and could be unsafe, but it is probably worth a try in case you’re suffering from long build times. I’ve seen project go down to 2.5 seconds when building after small code changes using the stuff I describe below. Hope it works for you as well.
Android uses Gradle for building. The default version of Gradle at the time of writing is 2.2. The latest version is 2.4 and has a huge performance boost over previous versions. In order to make your Android project use this version, add the following at the end of your root build.grade
script.
task wrapper(type: Wrapper) {
gradleVersion = '2.4'
}
