<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="me.upclose.aether"
          android:installLocation="auto">

    <!-- You need to set in your gradle file at least targetSdkaVersion=22-->
    <application android:vmSafeMode="true"/>
</manifest>

Also, you need targetSDKVersion 22

Good point. People is saying this should be used with:

dexOptions {
    preDexLibraries = false
}

to compile projects in less time than expected

Thanks Cesards, good tip :) 👍

Which task do you use for checking compile time difference? Or do you just use IDE's run command? And what changes do you apply between checks (edit code, resources, restart IDE...)?

@cesards sure? According to this https://plus.google.com/+AndroidDevelopers/posts/ECrb9VQW9XP preDex makes first build slower and subsequent builds faster.

Well, actually I'm not sure about anything related to Gradle, just saying together works better for me xD
