 ### Notes regarding supported languages and package managers
 
+1. Although Gradle with Java 8 is supported, there are other issues such that Android project builds are not supported at this time. Please see the backlog issue [Android support for Dependency Scanning (gemnasium-maven)](https://gitlab.com/gitlab-org/gitlab/-/issues/336866) for more details.

 1. The presence of a `Pipfile.lock` file alone will _not_ trigger the analyzer; the presence of a `Pipfile` is still required in order
 for the analyzer to be executed. However, if a `Pipfile.lock` file is found, it will be used by `Gemnasium` to scan the exact package
 versions listed in this file.
