![]() The linker will always run before the ProGuard step. The Xamarin.Android linker employs static analysis of your application This process usesĮach of these steps is described next. It works within the Xamarin.Android build process. One important item to know in advance before using ProGuard is how Xamarin.Android's ProGuard performs only the shrinking and (even through the use of custom configuration files). In fact, it is not possible to enable obfuscation through ProGuard The Xamarin.Android ProGuard configuration does not obfuscate theĪPK. Section, Xamarin.Android ProGuard uses only a subset of these This is the only step that doesn't have to know the entryĮach of these steps is optional. Preverification step – Performs checks on Java bytecodesĪhead of runtime and annotates class files for the benefit of the Step is not supported by Xamarin.Android because the app is compiled That they can still be accessed by their original names. Obfuscation step – In native Android development, ProGuard renames classes and class Points can be made private, static, or final, unused parameters canīe removed, and some methods may be inlined. Optimization step – ProGuard further optimizes the code.Īmong other optimizations, classes and methods that are not entry Shrinking step – ProGuard recursively determines whichĬlasses and class members are used. ![]() ProGuard processes input APK's using the following steps: ![]() Then shrinks, optimizes, and pre-verifies them it writes The ProGuard tool from the Android SDK will also optimize bytecodeĪnd remove unused code instructions. Referenced libraries (this can help you avoid the 64k reference limit). ProGuard detects and removes unused classes, fields, methods, andĪttributes from your packaged application. It also provides several examples of ProGuard configurations. This guide explains how ProGuard works, how to enable it in your project, and how to configure it. It detects and removes unused code, analyzes and optimizes bytecode. Xamarin.Android ProGuard is a Java class file shrinker, optimizer, and pre-verifier.
