smithmicro/android-build repository overview

⁠android-build

Dockerized Android Build image, smithmicro/android-build⁠. Optional versions with the NDK installed.

⁠Architecture

These Android build images are dereived from the official gradle⁠ image. We use the gradle:8.13-jdk17 image in the latest build which includes JDK 17. This gradle version is consistant with the version currently used by the latest version of Android Studio. Older images use gradle:7.4-jdk11 and gradle:6.5-jdk8.

The main software that is added to the non-NDK versions:

• Android SDK Tools - provides the sdkmanager command line tool
• Kotlin - installed via SDKMAN

The sdkmanager packages that are installed are generally the current version and the previous version. Check the Dockerfile for more details.

⁠Examples

Run the following command in your Android project. The directory should be same as your build.gradle file.

docker run --rm -v ${PWD}:/home/gradle/ smithmicro/android-build:36

The default command of this image is gradle build, but you can run others.

Run a gradle clean:

docker run --rm -v ${PWD}:/home/gradle/ smithmicro/android-build:36 gradle clean

Show installed sdkmanager packages:

docker run --rm smithmicro/android-build:36-ndk27 sdkmanager --list

⁠Build

To build all images containers in this repo, run:

./build.sh

⁠NDK Versions
