While Android Studio manages this process automatically behind the scenes, there are many scenarios—such as building automated CI/CD pipelines, writing custom build scripts, or debugging compilation issues—where you need to run the compiler standalone. To do that, you need to download d8.jar .

: D8 can compile DEX files up to 30% faster than its predecessor, DX.

The legitimate d8.jar is distributed inside the package. Here’s how to extract it: d8.jar download

is a command-line tool that compiles Java bytecode into DEX bytecode. The d8.jar file is the executable Java archive that contains the core logic of this compiler. It supports: Dexing: Converting .class files directly into .dex files. I can provide a precise command-line script tailored

If you want to compile a file named MainActivity.class for an app supporting API 24 and output it to a folder named build , use:

– The above is for desugaring libraries. For the actual d8.jar , it is not directly published as a standalone artifact. Instead, Google publishes com.android.tools.build:builder which includes D8. For pure D8, use:

java -cp /path/to/d8.jar com.android.tools.r8.D8 MyClass.class Use code with caution. 2. Compiling a Java JAR for Android : D8 can compile DEX files up to

When compiling Android-specific code, you must point D8 to the android.jar file located in your SDK's platforms folder.

Android features evolve with different API levels. If your application targets a specific minimum Android version, pass the --min-api flag. This tells D8 how to handle newer Java features:

You can find it by navigating to your Android SDK directory. The default paths are usually:
