Dockerfile for Android CI

My general usage (very up-to-date) Docker image for Android CI. Without anything other than the bare SDK.

Contains:

• Based on ubuntu:jammy 22.04
• with wget, curl, zip, python, python3, pip, rsyslog, git, make, gcc (and other build-essential)
• Corretto JDK17 - https://github.com/corretto/corretto-17/releases
• Compressed and squashed into one layer.

Accepting licenses

Getting an error when building Android with this Docker image? Something like this:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> You have not accepted the license agreements of the following SDK components:
  [Android SDK Platform 25, Android SDK Build-Tools 25.0.1].
  Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.
  Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

You'll need to create licenses folder with license files under ${ANDROID_HOME}. Accept the licenses on you local machine then create the same files inside the Docker image, using your CI script. Something like this:

echo -e "8933bad161af4178b1185d1a37fbf41ea5269c55\c" > ${ANDROID_HOME}/licenses/android-sdk-license
echo -e "79120722343a6f314e0719f863036c702b0e6b2a\n84831b9409646a918e30573bab4c9c91346d8abd\c" > ${ANDROID_HOME}/licenses/android-sdk-preview-license
echo -e "8403addf88ab4874007e1c1e80a0025bf2550a37\c" > ${ANDROID_HOME}/licenses/intel-android-sysimage-license

Also, due to a known bug, you'll need to run gradle twice. So:

./gradlew dependencies || true
./gradlew clean
