Android_SDK Compilation¶
SDK (Software Development Kit) is a collection of development tools provided for a specific software framework, hardware platform, or operating system, designed to help developers create their own solution more efficiently.
Build Environment¶
Install Ubuntu on a PC for SDK compilation.
- Hardware: PC with RAM ≥ 16 GB, CPU cores ≥ 4, Hard Drive ≥ 500GB
- Software: Ubuntu 22.04, Virtual Machine disk space allocation ≥ 200GB

Fetch SDK Source Code¶
Note
1. The SDK cannot be built in a HOST shared directory if using virtual machine as building env.
2. Do NOT build SDK as ROOT user.
1. Download the Android SDK source code and the release_sdk.sh script. Usually, select the file with the latest date suffix.
| SDK Version | Supported Boards | Maintained? |
|---|---|---|
| Android 13 | RK356x–RK3588 full series | No |
| Linux | RK356x–RK3588 full series | No |
| Android 14 | Only supports K1 MINI, K11C, K8D, K8C | Yes |
| linux‑kernel‑6.1 | Only supports K1 MINI, K11C, K8C, K8D | Yes |
2. Place the tar.gz package, md5sum file, and release_sdk.sh file in the same directory on the compilation host.
3. Run the script to restore the SDK source code.
Full Compilation¶
1. Enter the code path on the compilation host and execute the following command to configure the compilation target:
Select the configuration file according to the board model and SoC.
| Board | SoC | Configuration File |
|---|---|---|
| K1 | rk3568 | BoardConfig-rk3568-kickpi-k1.mk |
| K1B | rk3568 | BoardConfig-rk3568-kickpi-k1b.mk |
| K1 Mini | rk3568 | BoardConfig-rk3568-kickpi-k1Mini.mk |
| K3 | rk3562 | BoardConfig-rk3562-kickpi-k3.mk |
| K3B | rk3562 | BoardConfig-rk3562-kickpi-k3b.mk |
| K8 | rk3588 | BoardConfig-rk3588-kickpi-k8.mk |
| K8C | rk3588 | BoardConfig-rk3588-kickpi-k8c.mk |
| K8D | rk3588s | BoardConfig-rk3588s-kickpi-k8d.mk |
| K11C | rk3566 | BoardConfig-rk3566-kickpi-k11c.mk |

Individual Compilation¶
- Compile Multi-screen Recognition Image
- Compile Uboot Individually
- Compile Android Individually
- Compile Kernel Individually
- Configure Kernel defconfig
Q&A¶
- Android compilation error due to path errors caused by code location changes?
Clear the data first, then recompile.
- Insufficient compilation space?
The default building job count is currently -j32. Reducing the jobs, add the -J parameter followed by the jobs to the build command.
