# Gradle Build for Google Play
Use this skill when you need to build an Android app before uploading to Play Store.
## Build Types
### App Bundle (AAB) - Recommended
App Bundles are required for new apps on Google Play:
```bash
./gradlew bundleRelease
```
Output: `app/build/outputs/bundle/release/app-release.aab`
### APK - Legacy
For apps not using bundles:
```bash
./gradlew assembleRelease
```
Output: `app/build/outputs/apk/release/app-release.apk`
## Signing Configuration
### build.gradle (app level)
```groovy
android {
signingConfigs {
release {
storeFile file(System.getenv("KEYSTORE_FILE") ?: "release.keystore")
storePassword System.getenv("KEYSTORE_PASSWORD")
keyAlias System.getenv("KEY_ALIAS")
keyPassword System.getenv("KEY_PASSWORD")
}
}
buildTypes {
release {
signingConfig signingConfigs.release
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
```
### Environment Variables
```bash
export KEYSTORE_FILE=/path/to/release.keystore
export KEYSTORE_PASSWORD=your_keystore_password
export KEY_ALIAS=your_key_alias
export KEY_PASSWORD=your_key_password
./gradlew bundleRelease
```
## Version Management
### gradle.properties
```properties
VERSION_NAME=1.2.3
VERSION_CODE=123
```
### build.gradle
```groovy
android {
defaultConfig {
versionCode project.property('VERSION_CODE').toInteger()
versionName project.property('VERSION_NAME')
}
}
```
### Increment version
```bash
# Read current version
CURRENT_VERSION=$(grep VERSION_CODE gradle.properties | cut -d'=' -f2)
NEW_VERSION=$((CURRENT_VERSION + 1))
# Update gradle.properties
sed -i "" "s/VERSION_CODE=$CURRENT_VERSION/VERSION_CODE=$NEW_VERSION/" gradle.properties
# Build
./gradlew bundleRelease
```
## ProGuard/R8 Configuration
### Enable R8 (default in AGP 3.4+)
```groovy
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
```
### Generate mapping file
Mapping file location: `app/build/outputs/mapping/release/mapping.txt`
Upload to Play Console for crash symbolication:
```bash
gplay deobfuscation upload \
--package com.example.app \
--edit $EDIT_ID \
--apk-version 123 \
--type proguard \
--file app/build/outputs/mapping/release/mapping.txt
```
## Build Variants
### Product Flavors
```groovy
android {
flavorDimensions "version"
productFlavors {
free {
dimension "version"
applicationIdSuffix ".free"
}
paid {
dimension "version"
}
}
}
```
### Build specific flavor
```bash
./gradlew bundleFreeRelease
./gradlew bundlePaidRelease
```
## CI/CD Build
### GitHub Actions Example
```yaml
- name: Build Release AAB
run: |
echo "${{ secrets.KEYSTORE_BASE64 }}" | base64 -d > release.keystore
export KEYSTORE_FILE=release.keystore
export KEYSTORE_PASSWORD="${{ secrets.KEYSTORE_PASSWORD }}"
export KEY_ALIAS="${{ secrets.KEY_ALIAS }}"
export KEY_PASSWORD="${{ secrets.KEY_PASSWORD }}"
./gradlew bundleRelease
- name: Upload to Play Store
env:
GPLAY_SERVICE_ACCOUNT: ${{ secrets.PLAY_SERVICE_ACCOUNT }}
run: |
gplay release \
--package com.example.app \
--track internal \
--bundle app/build/outputs/bundle/release/app-release.aab
```
## Common Build Tasks
### Clean build
```bash
./gradlew clean bundleRelease
```
### Build with specific SDK versions
```bash
./gradlew bundleRelease -PminSdkVersion=21 -PtargetSdkVersion=34
```
### Build without tests
```bash
./gradlew bundleRelease -x test -x lint
```
### Build multiple variants
```bash
./gradlew bundle # Builds all variants
```
## Troubleshooting
### Build fails with signing errors
```bash
# Verify keystore
keytool -list -v -keystore release.keystore
```
### Check AAB contents
```bash
bundletool build-apks \
--bundle=app-release.aab \
--output=output.apks \
--mode=universal
unzip output.apks
```
### Verify version codes
```bash
./gradlew tasks --all | grep Version
```
## Best Practices
1. **Never commit keystores** - Store in secure location
2. **Use environment variables** for credentials
3. **Enable ProGuard/R8** for release builds
4. **Upload mapping files** after each release
5. **Increment version code** for every build
6. **Test release builds** before uploading
7. **Use App Bundles (AAB)** instead of APKs when possible

Skill source recorded
Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.
Review before install: Avoid automatic install
License: MIT
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.
Quality

Copies are not installs. Installation counts require a reported successful installation; they are not a blanket quality guarantee.
This page exposes the same decision, trust, audit, use-case, and install signals through the Registry API, so agents can rank this skill without scraping the UI.
