LibDetect identifies libraries in Android apps (APK) on the class level and provied a similarity score of the class under analysis and a reference class stored in LibDetect's database.

checkout and compile OPAL develop branch (http://www.opal-project.de/)
install OpenSSL (https://www.openssl.org/)
install enjarify (https://github.com/google/enjarify)
install MySQL (https://www.mysql.com/de/downloads/)
execute createDB.sql
configure config.txt

• set USER_NAME to the user who has access to the androidlib database described in createDB
• set PASSWD to the password of the user who has access to the androidlib database described in createDB
• set DB_URL to the url of the internal mysql connection of the androidlib database often it looks like this jdbc:mysql://localhost:3306/androidlib
• set OPENSSL_EXEC_CMD to the operating-system-dependent oppenssl-command in windows it looks like this cmd /c path/to/the/openssl/command/openssl.exe
• set OPENSSL_CONF_PATH to the path of the OpenSSL configuration file
• set ENJARIFY_EXEC_CMD to the execution path of enjarify in windows it looks like this cmd /c path/to/enjarify/command/enjarify.bat

fill the database with all downloaded JARs which were described in LibDetectDatabase.txt LibDetectDatabase.txt is structured in the following way.

• Files which were downloaded from maven have a maven prefix.
• Files which were downloaded by a previous google search have a google prefix.
• Files which were downloaded from Fdroid have a fdroid prefix.
• Files which were downloaded from a github search have a github prefix.
• Files which were downloaded via link have a direct link to the source.

After collecting all JAR files, you need to create a file with all JAR file paths and execute LibDetectStandAloneExecutor with the following arguments: write <path/to/list of JAR files>. The second argument should be the path to the previous created list of JAR files.

CodeMatch extracts libraries, checks the size, checks the author, checks if generated code is used, and compares the similarity score of apps. Thereby CodeMatch uses the algorithms of https://github.com/openpreserve/bitwiser and/or http://publica.fraunhofer.de/documents/N-264291.html While the algorithm of Bitwiser is integrated in CodeMatch, F2S2 is under a license of the Fraunhofer SIT (https://www.sit.fraunhofer.de/) and can be obtained from the authors of the paper http://publica.fraunhofer.de/documents/N-264291.html
