Read the first 7 Android Build System, Gradle & App Deployment flashcards as text

  1. What is the primary build tool used in Android development with Android Studio?

    Answer: Gradle

    Gradle is the official build system for Android, integrated into Android Studio and used for dependency management, compilation, and packaging.

  2. In an Android Gradle project, what does `compileSdkVersion` specify?

    Answer: The Android API level used to compile the app source code

    `compileSdkVersion` defines the API level against which the app is compiled, giving access to the APIs available in that version without affecting runtime behavior.

  3. Which file contains the module-level Gradle build configuration including dependencies and build types?

    Answer: app/build.gradle

    The `app/build.gradle` file contains the module-specific configuration including dependencies, build types, and product flavors.

  4. What is the purpose of `versionCode` in an Android app?

    Answer: It is an internal integer used by the Play Store to determine if an update is newer

    `versionCode` is an integer that must increase with each release; the Play Store uses it to determine update ordering, while `versionName` is the human-readable version shown to users.

  5. Which Gradle task produces a release-signed APK?

    Answer: assembleRelease

    The `assembleRelease` Gradle task compiles, packages, and signs the app with the release configuration, producing a release-ready APK.

  6. What is a 'build variant' in Android development?

    Answer: A combination of a build type and a product flavor

    A build variant is the combination of a build type (e.g., debug, release) and a product flavor (e.g., free, paid), allowing different versions of the app to be built from the same source.

  7. Where is the Gradle wrapper version for an Android project specified?

    Answer: gradle/wrapper/gradle-wrapper.properties

    The `gradle/wrapper/gradle-wrapper.properties` file specifies the Gradle distribution URL, ensuring all team members and CI systems use the same Gradle version.
