What it does

Gplay Gradle Build is an agent skill from hanamizuki/solopreneur. Build, sign, and package Android apps with Gradle before uploading to Google Play. Use when asked to create an APK or AAB, configure signing, or set up build pipelines.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `_VENDOR.md`).

It sits in DevOps & Cloud, covering CI/CD and Android development. It works with Gradle and Android. The repository describes itself as: Skills and agents for solopreneurs — ship, review, debug, and think through problems with AI. The licence is MIT.

When your agent uses it

Asked to create an APK
Configure signing
Set up build pipelines

Example prompts

“/gplay-gradle-build”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

Never commit keystores - Store in secure location
Use environment variables for credentials
Enable ProGuard/R8 for release builds
Upload mapping files after each release
Increment version code for every build
Test release builds before uploading
Use App Bundles (AAB) instead of APKs when possible

What it can do on your machine

Read from SKILL.md and the folder at commit f43f001. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash, groovy, properties and yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- KEYSTORE_PASSWORD
- KEY_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gplay Gradle Build loads about 1.2k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 175 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~47
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

The full file from hanamizuki/solopreneur at commit f43f001, republished under its MIT licence (© hanamizuki). 175 words, ~1,210 tokens.

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

Never commit keystores - Store in secure location
Use environment variables for credentials
Enable ProGuard/R8 for release builds
Upload mapping files after each release
Increment version code for every build
Test release builds before uploading
Use App Bundles (AAB) instead of APKs when possible
