Gradle - Build Types

buildTypes { //Build Configuration block release { //Release Configuration Block minifyEnabled false // if true shrinks code proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

//proguard file } }

Sample build types snippet

Build types will allow you to configure - the settings that affect the building of the module, you can configure debug and release.

minifyEnabled true . //if true shrinks code

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt')

// defines the file where the proguard configuration is

the main purpose of the minifyEnabled true, is to enable the code shrinking in the appropriate build type

How the device is shrinked, is defined inside the proguard file.
