name: android-release description: Build, sign, and prepare Android APK and AAB for release. Handles version bumping, building, zipalign (APK), and signing with JKS keystore. Outputs DecentPaste_x.x.x.apk for GitHub releases and signed AAB for Play Console.

Android Release

Build signed APK (GitHub) and AAB (Play Console).

1. Gather Info

Ask user for: version (x.x.x), JKS keystore path, keystore alias. Never ask for password - user enters it during signing.

2. Update Versions

Use /bump-version workflow to update all 4 config files.

3. Build

cd decentpaste-app && yarn tauri android build && cd ..

Outputs (from project root):

• APK: decentpaste-app/src-tauri/gen/android/app/build/outputs/apk/universal/release/app-universal-release-unsigned.apk
• AAB: decentpaste-app/src-tauri/gen/android/app/build/outputs/bundle/universalRelease/app-universal-release.aab

4. Sign APK

Zipalign BEFORE signing (Claude runs):

zipalign -v 4 <unsigned-apk> DecentPaste_VERSION_aligned.apk

Signing (user runs - contains password):

apksigner sign --ks <keystore> --ks-key-alias <alias> --out DecentPaste_VERSION.apk DecentPaste_VERSION_aligned.apk

After user confirms, delete aligned file.

5. Sign AAB

Use jarsigner not apksigner - AABs are JAR-like bundles. No zipalign needed.

User runs:

jarsigner -verbose -sigalg SHA256withRSA -digestalg SHA-256 -keystore <keystore> <aab-path> <alias>
cp <aab-path> DecentPaste_VERSION.aab

6. Verify & Report

apksigner verify --verbose DecentPaste_VERSION.apk
jarsigner -verify -verbose DecentPaste_VERSION.aab

Report: files created, versions updated, next steps (commit, tag, upload).
