The goal of this repository is to demonstrate how to use Halide generators in an Android application.

Halide is a programming language designed to make it easier to write and maintain high-performance image processing code.

You can learn more about Halide from these sources:

• https://halide-lang.org
• https://blog.minhazav.dev/write-fast-and-maintainable-code-with-halide

In this sample app, I use invert_generator.cpp generator to invert the colors of an image. When the button is pressed, the display mode changes.

This works on macOS, but may require modifications on Windows and Linux. Pull requests are welcome!

On macOS you should have the Clang compiler (you can check it in the terminal by executing clang --version).

Supported ABIs: armeabi-v7a, arm64-v8a, x86, x86_64
Android min SDK: 24
Android compile and target SDK: 34
NDK version: 25.2.9519653
CMake version: 3.22.1

To make the project build, you need to:

1. Download Halide from https://github.com/halide/Halide/releases (I used Halide-16.0.0-arm-64-osx) and extract the archive
2. Add the following line to local.properties: halide.dir=path_to_the_extracted_halide_archive
3. Build the project as you typically do.

These tasks are performed automatically before building the app:features:processing module.

./gradlew buildDebugHalideGeneratorsTask

./gradlew buildReleaseHalideGeneratorsTask
