android project, it depends on ncnn library and opencv\n\nhttps://github.com/Tencent/ncnn\n\nhttps://github.com/nihui/opencv-mobile\n\n## android apk file download\nhttps://github.com/nihui/ncnn-android-nanodet/releases/latest\n\n## how to build and run\n### step1\nhttps://github.com/Tencent/ncnn/releases\n\n* Download ncnn-YYYYMMDD-android-vulkan.zip or build ncnn for android yourself\n* 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**\n\n### step2\nhttps://github.com/nihui/opencv-mobile\n\n* Download opencv-mobile-XYZ-android.zip\n* 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**\n\n### step3\n* Open this project with Android Studio, build it and enjoy!\n\n## some notes\n* Android ndk camera is used for best efficiency\n* Crash may happen on very old devices for lacking HAL3 camera interface\n* All models are manually modified to accept dynamic input shape\n* Most small models run slower on GPU than on CPU, this is common\n* FPS may be lower in dark environment because of longer camera exposure time\n\n##
