# Android Vulkan + Dear ImGui Example
A standalone Android application that renders [Dear ImGui](https://github.com/ocornut/imgui) using the Vulkan graphics API via `NativeActivity`. No Java/Kotlin code required — pure C++.
A standalone Android application that renders [Dear ImGui](https://github.com/ocornut/imgui) using the Vulkan graphics API. It is built natively in C++ via `NativeActivity`, alongside a minimal Java subclass to handle OS-level features like the virtual keyboard and clipboard.
![ImGui Demo](https://img.shields.io/badge/ImGui-1.92.6-blue) ![Vulkan](https://img.shields.io/badge/Vulkan-1.0-red) ![Android](https://img.shields.io/badge/Android-API%2026+-green)
## Features
- **Pure native** — `NativeActivity` with `android_native_app_glue`, no Java layer
- **Native focus** — `NativeActivity` with `android_native_app_glue` to handle the main loop purely in C++.
- **Keyboard & Clipboard** — Includes a minimal `MainActivity.java` subclass to provide JNI hooks for the Android soft keyboard and native `ClipboardManager`.
- **Vulkan rendering** — Instance, Device, Swapchain, RenderPass all managed via ImGui helpers
- **Touch input** — `imgui_impl_android.h` handles multi-touch natively
- **Orientation handling** — Swapchain auto-rebuilds on rotation
