This project is a simple demo of how to compile&run native **Aarch64** (or **x86**) binary on a Android device.
|
||
|
|
|
||
|
|
# TL;DR
|
||
|
|
|
||
|
|
*.bashrc*
|
||
|
|
```bash
|
||
|
|
export ANDROID_NDK="~/bin/android-ndk/r26c-linux"
|
||
|
|
export ANDROID_SDK_ROOT="~/bin/android_sdk_root"
|
||
|
|
export PATH="$PATH:$ANDROID_SDK_ROOT/cmdline-tools/latest/bin:$ANDROID_SDK_ROOT/emulator:$ANDROID_SDK_ROOT/platform-tools"
|
||
|
|
```
|
||
|
|
|
||
|
|
# Compile with Android NDK
|
||
|
|
|
||
|
|
- [Download](https://developer.android.com/ndk/downloads) latest version of Android NDK. I'm going go use Linux distribution.
|
||
|
|
- Set `ANDROID_NDK` Environment Variable to the extracted contents of an archive.
|
||
|
|
- At this point you should be able to compile the project with `compile.sh` script.
|
||
|
|
|
||
|
|
# Run
|
||
|
|
|
||
|
|
Technically, if you have Android device with `Development Mode ON` and `adb` binary somewhere on your host PC - you shall be able to install and execute compiled artifact from previous step with help of `run.sh` script. If that is not what you want or have - next sections are for you.

|
|
||
|
|
## cmdline-tools
|
||
|
|
|
||
|
|
- [Download](https://developer.android.com/studio#command-tools) Command line tools only.
|
||
|
|
- Set `ANDROID_SDK_ROOT` Environment Variable to the extracted contents of downloaded archive. It is recommended to follow next convention:
|
||
|
|
`$ANDROID_SDK_ROOT/cmdline-tools/latest/bin`
|
||
|
|
- Add it to `PATH`.
|
||
|
|
|
||
|
|
## sdkmanager
|
||
|
|
|
||
|
|
- List available packages with:
|
||
|
|
```bash
|
||
|
|
sdkmanager --list
|
||
|
|
```
|
||
|
|
|
||
|
|
> [!NOTE] QEMU host limitations
|
||
|
|
> It looks that Android API 27 is the latest officially supported OS image that is capable of being executed as **Aarch64** Android on **x86_64** host. Later versions of Android can be used only as **x86_64** binaries.
|
||
|
|
|
||
|
|
- Install packages for Android API 27 (MARSHMELLOW (6.0), etc)
|
||
|
|
```bash
|
||
|
|
sdkmanager "system-images;android-27;default;arm64-v8a" "platforms;android-27"
|
||
|
|
```
|
||
|
|
|
||
|
|
## emulator
|
||
|
|
|
||
|
|
- Install emulator and tools:
|
||
|
|
```bash
|
||
|
|
sdkmanager "emulator" "platform-tools"
|
||
|
|
```
|
||
|
|
|
||
|
|
- Add tools to `PATH`: `$ANDROID_SDK_ROOT/emulator`, `$ANDROID_SDK_ROOT/platform-tools`
|
||
|
|
|
||
|
|
- Create emulator device:
|
||
|
|
```bash
|
||
|
|
avdmanager --verbose create avd --force --name "pixel_6.0_27" --device "pixel" --package "system-images;android-27;default;arm64-v8a" --tag "default" --abi "arm64-v8a"
|
||
|
|
```
|
||
|
|
|
||
|
|
- Start emulator:
|
||
|
|
```bash
|
||
|
|
emulator @pixel_6.27 -qemu -machine virt
|
||
|
|
```
|
||
|
|
|
||
|
|
> [!NOTE] -qemu -machine virt
|
||
|
|
> This two options are only necessary if you are going to run **Aarch64** Android on a **x86_64** host.
