About

smali/baksmali is an assembler/disassembler for the dex format used by dalvik, Android's Java VM implementation. The syntax is loosely based on Jasmin's/dedexer's syntax, and supports the full functionality of the dex format (annotations, debug info, line info, etc.)

NOTE: This is a fork of https://github.com/JesusFreke/smali for patches needed by Google as the original repository is currently not maintained. After forking the namespace was changed from org.jf to com.android.tools.smali. The artifacts are released on Google Maven under the following coordinates:

• com.android.tools.smali:smali:<version>
• com.android.tools.smali:smali-dexlib2:<version>
• com.android.tools.smali:smali-baksmali:<version>
• com.android.tools.smali:smali-util:<version>

After the fork the first version released was 3.0.0, which was version 2.5.2 from the original repo with a few patches and the namespace change.

Building and testing

All building and testing should be done using a version of OpenJDK 11. Newer OpenJDK versions are currently not supported due to issues with some of the tools used in the build process.

Building

./gradlew assemble

Command Line Version

To run the smali and baksmali tools from the command line build the fat jars. The fat jars will be named with the current version followed by the first 8 characters of the current git hash followed by an optional -dirty if the repository was dirty when building and ending in -fat . The fat jar can be invoked with java -jar.

./gradlew smali:fatJar
java -jar smali/build/libs/smali-x.y.z-aaaaaaaa-dirty-fat.jar

Testing

To execute all tests run

./gradlew test

Testing Maven Release

Push a release version to your local maven repository (add -Dmaven.repo.local=<dir> to override the default local maven repository location)

./gradlew release publishToMavenLocal

Releasing

Building release versions and releasing to Google Maven use Google infrastructure and support scripts maintained as part of the R8 repository. The tasks below can only be performed by Google employees.

Prepare and build a release version

To prepare a release update build.gradle with the next release version and commit that. Then create a tag for that commit with the version.

git tag <version> <commit>
git push origin <version>

Release versions can then be built by the Google R8 team using:

tools/trigger.py --smali=<version> --release

in the R8 repository.

The status of the build on the bot is at https://ci.chromium.org/p/r8/builders/ci/smali.

Releasing to Google Maven

When a release version has been built on the bot, it can be released to Google Maven by running

tools/release_smali.py --version=<version>

in the R8 repository. This kick off an internal Google approval process to finalize the release.
