Setup

Java

JDK 17 is required (app/build.gradle.kts sets the Java toolchain to 17). Debian 13 has no openjdk-17 package, so install Eclipse Temurin 17 manually from Adoptium:

wget -O temurin17.tar.gz "https://api.adoptium.net/v3/binary/latest/17/ga/linux/x64/jdk/hotspot/normal/eclipse?project=jdk"
mkdir -p ~/jdks
tar -xzf temurin17.tar.gz -C ~/jdks

Set JAVA_HOME to the unpacked directory and select JDK 17 as the Gradle JDK in Android Studio (Settings -> Build, Execution, Deployment -> Build Tools -> Gradle -> Gradle JDK). Using a newer JDK (e.g. 21) breaks the build with class file has wrong version 65.0, should be 61.0.

Formatting

• Install ktlint plugin
• For automated formatting, Install Ktlint plugin to IDEA then you can go to Settings -> Tools -> KtLint -> Distract free.
• For manual formatting you can use Command+Option+Enter.

Wildcard imports

For disabling wildcards go to Settings -> Editor -> Code style -> Kotlin -> Imports Choose Use single name import for all cases and uncheck all checkboxes below.

Submodules

git submodule update --init --recursive

Install conan

(For Windows, refer to these instructions to install all required dependencies.)

pip install conan numpy

sudo apt install clang

Create profile, get your conan home path

conan config home

conan profile detect -f

Go to the following path and open the profiles folder. For example, on my system, the path is: ~/.conan2/profiles

Then, create a file named android-studio with the following content:

include(default)

[settings]
os=Android
os.api_level=28
compiler=clang
compiler.version=20
compiler.libcxx=c++_static
compiler.cppstd=17

[tool_requires]
*: android-ndk/r28b

[Hack] If above config doesn't help, install ndk 29.0.13599879 and point it out in 3 places:

• app/build.gradle.kts in android section, for example

      ...
      ndkVersion = "28.1.13356709"
      ...
  

• local.properties

      ndk.dir=/Users/<user-name>/Library/Android/sdk/ndk/28.1.13356709
  

• ~/.conan2/profiles/android-studio in conf section

      ...
      [conf]
      tools.android:ndk_path=/Users/ddeviatilov/Library/Android/sdk/ndk/28.1.13356709
      ...
