To build and run lune for android, you need to do the following:

- Set up your cargo config:

```toml
[target.aarch64-linux-android]
ar = "$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-ar"
rustflags = ["-C", "linker=aarch64-linux-android-clang", "-C", "link-args=-rdynamic", "-C", "default-linker-libraries"]
linker = "$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-clang"
```

- The latest android NDK has paths different from those that cargo expects, so we need to create the following symlinks:
   - `$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin/llvm-ar -> aarch64-linux-android-ar`
  - `$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android33-clang -> aarch64-linux-android-clang`

- Make sure that `$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/bin` is in your path.

- Build the binary: 

```sh
cargo build --release --target aarch64-linux-android
```
- The compiled output can be found at: `./target/aarch64-linux-android/release/lune`

- To run lune, we'll need `libc++` for the linker as `libc` is always linked dynamically by cargo. We can find the library at `$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/lib/aarch64-linux-android/libc++_shared.so`.

- On android, store the `libc++_shared.so` file at `$PREFIX/lib/libc++_shared.so`.

- Add the `$PREFIX/lib` to LD_LIBRARY_PATH.

```sh
export LD_LIBRARY_PATH=$PREFIX/lib
```

- Run lune.
- Profit?
