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).
