ApkBuilder

ApkBuilder is a lightweight Android build tool designed for Termux.
It bundles essential Android build utilities to compile and package APKs without Android Studio or Gradle.

This project is focused on simplicity and portability, allowing Android apps to be built directly from the command line on Android devices.

Project/
 └── app/
     ├── libs/ (project libraries)
     └── src/
         └── main/
             ├── assets/        (optional)
             ├── jniLibs/       (optional)

Requirements (Android / Termux)

Before using ApkBuilder, make sure you have the following installed in Termux:

• Kotlin compiler (kotlinc)

• AAPT2

• D8

• apksigner

pkg install -y openjdk-17 kotlinc aapt2 d8 apksigner

Building an APK

To compile your project, use the builder.py module:

python builder.py <PROJECT_PATH> --min-sdk <MIN_SDK> --target-sdk <TARGET_SDK> --version-code <VERSION_CODE> --version-name <VERSION_NAME> --view-binding <ENABLE_VIEW_BINDING>

Example

python builder.py example_project/ --min-sdk 21 --target-sdk 34 --version-code 1 --version-name "1.0" --view-binding True

This will compile the project, generate DEX files, package resources, and produce a signed APK.
