ncnn-android-rvm

RVM

This is a sample ncnn android project, it depends on ncnn library and opencv

how to build and run

step1

https://github.com/Tencent/ncnn/releases

• Download ncnn-YYYYMMDD-android-vulkan.zip or build ncnn for android yourself
• Extract ncnn-YYYYMMDD-android-vulkan.zip into app/src/main/jni and change the ncnn_DIR path to yours in app/src/main/jni/CMakeLists.txt

step2

https://github.com/nihui/opencv-mobile

• Download opencv-mobile-XYZ-android.zip
• Extract opencv-mobile-XYZ-android.zip into app/src/main/jni and change the OpenCV_DIR path to yours in app/src/main/jni/CMakeLists.txt

step3

https://github.com/nihui/mesa-turnip-android-driver

• Download mesa-turnip-android-XYZ.zip
• Create directory app/src/main/jniLibs/arm64-v8a if not exists
• Extract libvulkan_freedreno.so from mesa-turnip-android-XYZ.zip into app/src/main/jniLibs/arm64-v8a

step4

• Open this project with Android Studio, build it and enjoy!

some notes

• Android ndk camera is used for best efficiency
• Crash may happen on very old devices for lacking HAL3 camera interface
• All models are manually modified to accept dynamic input shape
• Most small models run slower on GPU than on CPU, this is common
• FPS may be lower in dark environment because of longer camera exposure time
