Android setup on MacOS

Install necessary packages

Use crossbundle install command or download and install Android Studio.
Start Android Studio, and go through the Android Studio Setup Wizard with the Custom option and install the following (or install them in SDK Manager):
- Android SDK
- NDK (Side by side)
- Android SDK Command-line Tools
- Android SDK Build-Tools
- Android SDK Platform-tools
Download and install java. Can be installed with brew through:

brew tap adoptopenjdk/openjdk
brew install --cask adoptopenjdk8

Install necessary rustup targets

Run the following command:

rustup target add armv7-linux-androideabi aarch64-linux-android i686-linux-android x86_64-linux-android

Add environment variables

From the Start search bar, enter ‘env’ and select Edit environment variables for your account.

Building strategy	Key	Value	Description
Gradle project, native APK/AAB	ANDROID_SDK_ROOT	<path_to_sdk>\Sdk	Can be replaced with ANDROID_SDK_PATH and ANDROID_HOME. You might not install this env var if you used crossbundle install to set up required packages
			or just want to build native APK or native AAB
Native APK/AAB	ANDROID_NDK_ROOT	<path_to_sdk>\Sdk\ndk<version>	Can be replaced with ANDROID_NDK_PATH and NDK_HOME. You might not install this env var if you used crossbundle install to set up required packages
Gradle project	GRADLE_HOME	<path_to_gradle>	Crossbow default build process requires installed Gradle on your PC. You can download it here
Native AAB	BUNDLETOOL_PATH	<path_to_bundletool>	Download bundletool from the `GitHub repository` or use crossbundle install

For that edit ~/.bash_profile/~/.bashrc or ~/.zshrc files so they contain those lines:

export ANDROID_SDK_ROOT=$HOME/android/sdk
export ANDROID_NDK_ROOT=$ANDROID_SDK_ROOT/ndk/23.1.7779620
export GRADLE_HOME=<path_to_gradle>
export BUNDLETOOL_PATH=<path_to_bundletool>

Also, we need to make sure we have a java runtime environment (JRE) installed. We will need a key tool utility from there.
To make sure it's present type this command: ls /usr/lib/jvm/default/bin/ | grep keytool or add to your PATH env var.
