I used Android SDK Manager to download the latest version of Android SDK. But ProGuard was not updated and remained at version 4.7.
Is it necessary to manually download ProGuard from its website and unzip it to \android-sdk\tools\proguard ?
Or will Android SDK always use Version 4.7? It has been this way for 4 years.
These days ProGuard is a dependency of the Android Gradle plugin, and is usually updated along with it. Looking at the output of ./gradlew buildEnvironment (supported since Gradle 2.10) you will see something like
classpath +--- com.android.tools.build:gradle:2.2.3 | \--- com.android.tools.build:gradle-core:2.2.3 ... | +--- net.sf.proguard:proguard-gradle:5.2.1 | | \--- net.sf.proguard:proguard-base:5.2.1 If you want to use another ProGuard version than the one the Android Gradle plugin depends on you can override it like
buildscript { configurations.all { resolutionStrategy { // We want version 5.3.2 instead of 5.2.1. force 'net.sf.proguard:proguard-gradle:5.3.2' } } } Modify your build.gradle like so:
// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { ... dependencies { classpath 'net.sf.proguard:proguard-gradle:6.1.1' // <-- Add this line ... } } You don't have to manually download it.
Do not use a force resolution strategy to upgrade Proguard. Instead declare the dependency in the Top-level build.gradle file such as -
buildscript { dependencies { classpath 'net.sf.proguard:proguard-gradle:6.1.1' } }
