 To build for Android, you need a few SDKs! [Android Studio](https://developer.android.com/studio) has a good interface for grabbing these, and doubles as a nice tool for inspecting APKs.

+### If building on Linux (CLI): Quick setup
+If you prefer the command line on Linux, this is a minimal setup that matches the versions this template targets.
+
+```bash
+# 1) Base tools
+sudo apt update
+sudo apt install cmake libx11-dev libxfixes-dev libegl-dev libgbm-dev libfontconfig-dev unzip curl zip ninja-build openjdk-8-jdk adb google-android-cmdline-tools-13.0-installer

+# 2) to rule out potential errors, we explicitly tell sdkmanager where to install the Android SDK & NDK
+
+export ANDROID_HOME="$HOME/Android/Sdk"
+
+sdkmanager --sdk_root=$ANDROID_HOME \
+  "platform-tools" \
+  "platforms;android-32" \
+  "build-tools;32.0.0" \
+  "ndk;25.2.9519653"
+
+# 3) More environment variable setup...:
+
+export ANDROID_SDK_ROOT="$ANDROID_HOME"
+export PATH="$ANDROID_HOME/platform-tools:$PATH"

+# 5) Point CMake to the NDK and set JAVA_HOME (OpenJDK 8 on Ubuntu)
+export ANDROID_NDK_HOME="$ANDROID_HOME/ndk/25.2.9519653"
+export JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"
