+# RobinSR on Android (but without termux)
+I haven't tested this myself since my device can't run HSR, but I did test the server with my phone as the host while running the game on PC. This is just a proof of concept anyway (I'm new to Android development 😭).
+
+## Building from Source  
+**Note:** This README might not include all steps. If you encounter any errors, you may need to look up additional information yourself.  
+
+### Prerequisites  
+
+You'll need:  
+- Android Studio  
+- Android SDK & NDK  
+- Rust nightly  
+
+### 1. Install Android SDK & NDK  
+
+Install [Android Studio](https://developer.android.com/studio) and set up the required SDKs.  
+
+### 2. Install Rust & Cargo NDK  
+
+Install [Rust](https://www.rust-lang.org/tools/install). RobinSR requires Rust nightly:  
+
+```sh
+rustup toolchain install nightly
+rustup default nightly
+```  
+
+Add required targets:  
+
+```sh
+rustup target add aarch64-linux-android armv7-linux-androideabi x86_64-linux-android
+```  
+
+Install `cargo-ndk`:  
+
+```sh
+cargo install cargo-ndk
+```  
+
+### 3. Configure Android NDK Path  
+
+Set `ANDROID_NDK_HOME`:  
+
+```sh
+set ANDROID_NDK_HOME=%ANDROID_SDK_ROOT%\ndk\{ndk-version}
+```  
+
+For PowerShell:  
+
+```powershell
+$env:ANDROID_NDK_HOME="$env:ANDROID_SDK_ROOT\ndk\{ndk-version}"
+```  
+
+Replace `{ndk-version}` accordingly.  
+
+### 4. Verify Installation  
+
+Check if everything is installed:  
+
+```sh
+rustc --version
+cargo --version
+cargo ndk --help
+```  
+
+After this, build the project from android studio.
