💡 Hint

Common Mistakes

Using 'pull_request' instead of 'push' triggers workflow on pull requests, not pushes.

The push event triggers the workflow whenever code is pushed to the repository.

💡 Hint

Common Mistakes

Choosing 'windows-latest' or 'macos-latest' will run on different OS, not Ubuntu.

The ubuntu-latest label runs the job on the latest Ubuntu virtual environment.

steps:
  - name: Checkout code
    uses: [1]

Aactions/setup-java@v3

Bactions/checkout@v1

Cactions/checkout@v3

Dactions/upload-artifact@v2

Attempts:

💡 Hint

Common Mistakes

Using older versions like v1 may lack features or cause errors.

The latest stable version of the checkout action is actions/checkout@v3, which ensures compatibility and new features.

Fill both blanks to set up Java and cache Gradle dependencies.

Android Kotlin

steps:
  - uses: actions/setup-java@v3
    with:
      java-version: [1]
  - name: Cache Gradle packages
    uses: actions/cache@v3
    with:
      path: ~/.gradle/caches
      key: gradle-[2]

Drag options to blanks, or click blank then click option'

Attempts:

💡 Hint

Common Mistakes

Using Java 11 may work but 17 is recommended. Using a static cache key can cause cache conflicts.

Java version 17 is the current LTS for Android builds. Using runner.os in the cache key helps create OS-specific cache keys.

Fill all three blanks to build the Android app using Gradle and upload the APK artifact.

Android Kotlin

steps:
  - name: Build with Gradle
    run: ./gradlew [1] assemble[2]
  - name: Upload APK
    uses: actions/upload-artifact@v2
    with:
      name: app-release
      path: app/build/outputs/apk/[3]/app-release.apk

Drag options to blanks, or click blank then click option'

BRelease

Crelease

Dbuild

Attempts:

💡 Hint

Common Mistakes

Using 'Debug' instead of 'Release' builds a debug APK, not suitable for release.

Running clean ensures a fresh build. The task assembleRelease builds the release APK. The path uses the 'release' folder for the APK.
