Clone with Git Instead of ZIP: The safest method is to git clone the repository. Then, within the cloned directory, run git log --show-signature to verify commit signatures. You can also check the latest tag’s signature. Cloning gives you the full history and the ability to verify integrity against known hashes.

Hash Verification (If Provided): Some responsible projects publish SHA-256 or MD5 hashes of their release ZIP files on their official website or a trusted release page. After downloading the ZIP, you can compute its hash using command-line tools (shasum -a 256 file.zip on macOS/Linux) and compare it to the published hash. A mismatch indicates corruption or tampering. Once sync succeeds, do not just hit Run

Inspect the Project Before Building: Even after downloading, open the build.gradle files (both project-level and module-level) in a text editor before importing into Android Studio. Look for:

Use Dependabot and Security Advisories: GitHub automatically scans for known vulnerabilities. If you download a ZIP of an old commit, you might be pulling in a version of a library with a known security flaw (e.g., a vulnerable version of OkHttp or Apache Commons). Always check the “Security” tab of the repository.
