Quick answer: Godot Android AAB export failing with “keystore not found” or signature errors? Configure the keystore path in Editor Settings + the project’s alias and passwords in the export preset.

Trying to export a release AAB; the build aborts at sign time because the keystore isn’t found.

Editor Settings Keystore

Editor → Editor Settings → Export → Android. Set Debug Keystore path and Release Keystore path. Each requires the .keystore / .jks file.

Per-Export Preset

Project Export → Android preset → Keystore section. Alias, alias password, keystore password all required for release. Use environment variables for CI secrets.

Generate a Release Keystore

keytool -genkey -v -keystore my-release.jks -alias my-alias \
  -keyalg RSA -keysize 2048 -validity 10000

Generate once per project; keep secure backup. Losing the keystore means you can’t update the app on Play Store.

Play Integrity / App Signing

Google Play’s App Signing manages the upload key separately. Your upload keystore signs uploads; Google re-signs with the app signing key. Make sure the upload key is registered.

Verifying

Release AAB builds and signs without errors. Upload to Play Console succeeds.

“Release AAB needs keystore in editor settings plus alias/password in preset.”

Back up the release keystore in two secure places — lose it once and the app is functionally orphaned from Play Store updates.
