+# Description
+
+This is a guide on how to build the rust SDK for AppFlowy on android.
+Compiling the sdk is easy it just needs a few tweaks.
+When compiling for android we need the following pre-requisites:
+
+- Android NDK Tools. (v24 has been tested).
+- Cargo NDK. (@latest version).
+
+**Getting the tools**
+- Install cargo-ndk ```bash cargo install cargo-ndk```.
+- [Download](https://developer.android.com/ndk/downloads/) Android NDK version 24.
+- When downloading Android NDK you can get the compressed version as a standalone from the site.
+    Or you can download it through [Android Studio](https://developer.android.com/studio).
+- After downloading the two you need to set the environment variables. For Windows that's a seperate process.
+    On MacOs and Linux the process is similar.
+- The variables needed are '$ANDROID_NDK_HOME', this will point to where the NDK is located.
+---
+
+**Cargo Config File**
+This code needs to be written in ~/.cargo/config, this helps cargo know where to locate the android tools(linker and archiver).
+**NB** Keep in mind just replace 'user' with your own user name. Or just point it to the location of where you put the NDK.
+
+```toml
+[target.aarch64-linux-android]
+ar = "/home/user/Android/Sdk/ndk/24.0.8215888/toolchains/llvm/prebuilt/linux-x86_64/bin/llvm-ar"

+linker = "/home/user/Android/Sdk/ndk/24.0.8215888/toolchains/llvm/prebuilt/linux-x86_64/bin/x86_64-linux-android29-clang"
+```
+
+**Clang Fix**
+ In order to get clang to work properly with version 24 you need to create this file.
+ libgcc.a, then add this one line.
+ ```
+ INPUT(-lunwind)
+ ```
+
+**Folder path: 'Android/Sdk/ndk/24.0.8215888/toolchains/llvm/prebuilt/linux-x86_64/lib64/clang/14.0.1/lib/linux'.**
+After that you have to copy this file into three different folders namely aarch64, arm, i386 and x86_64.
+We have to do this so we Android NDK can find clang on our system, if we used NDK 22 we wouldnt have to do this process.
+Though using NDK v22 will not give us alot of features to work with.
+This github [issue](https://github.com/fzyzcjy/flutter_rust_bridge/issues/419) explains the reason why we are doing this.
+
+ ---
+
+ **Android NDK**
+
+ After installing the NDK tools for android you should export the PATH to your config file
+ (.vimrc, .zshrc, .profile, .bashrc file), That way it can be found.
+
+ ```vim
+ export PATH=/home/sean/Android/Sdk/ndk/24.0.8215888
+ ```
