Creedengo Android Java

Creedengo is a collective project aiming to reduce the environmental footprint of software at the code level. This repository hosts the Android-focused plugin, originally released as ecoCode android and now branded as Creedengo Android Java.

It provides static code analyzers to highlight code structures that may have a negative ecological impact: energy over-consumption, "fatware", shortening devices' lifespan, etc.

The project is based on an evolving catalog of best practices for Android. A SonarQube plugin implements this catalog as rules for scanning native Android projects written in Java only.

🌿 SonarQube plugin

_{The custom GUI above is reserved to educational purpose only.}

This plugin targets:

• Android Java source code
• Android XML configurations
• Gradle build files (Groovy)

🚀 Quickstart

A SonarQube container image with Creedengo Android Java embedded exists!

docker run -ti --rm \
       -v sq_creedengo_android_logs:/opt/sonarqube/logs \
       -v sq_creedengo_android_data:/opt/sonarqube/data \
       -p 9000:9000 \
       --name sonarqube-creedengo-android  \
       ghcr.io/green-code-initiative/sonarqube-creedengo-android:latest

Wait a little bit during first start initialization, and go to http://localhost:9000. Default credentials are admin/admin

🛒 Distribution

Ready to use binaries are available from GitHub.
