Library missing namespace (AGP 8+)

Android / Gradle · last reviewed 2026-11-10

The error looks like this

Namespace not specified. Specify a namespace in the module's build file.

Why it happens

An old library's build.gradle lacks the namespace AGP 8 requires.

How to fix it

  1. Upgrade the library named in the log.
  2. Temporary: patch-package to add namespace "<its package>" to its android block.

Not sure this is your error? Let ReleaseMedic read the whole log

Build logs are long and the last line is rarely the real cause. ReleaseMedic finds the first real error, explains it and gives the steps — free, and the log never leaves your computer.

$ npx releasemedic log build.log

Or pipe a build straight in: cd android && ./gradlew bundleRelease 2>&1 | npx releasemedic log -

Catch it before you build

Most release errors come from project settings you can check in seconds — signing, SDK levels, privacy manifests, permissions, push and login setup.
