How do I change Project language level on Android Studio

Question

I would like to set the Java version I\'m using on Android Studio.

How do I set the \'Project language level\' like I do on Intellij inside \'Project Structure...\'

Answer 1

You can also edit this inside the Project Structure

Answer 2

Sample build.gradle file which allows me to use lambdas in Android Studio 2.1:

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.geniuscreations.successtaskanalyzer"
    minSdkVersion 17
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    jackOptions {
        enabled true
    }
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
}
