• You can refer to dlib-android-app which demonstartes dlib-android features

Grab the source

$ cd ~
$ git clone --recursive https://github.com/tzutalin/dlib-android.git

Prerequisites

• Download Android-NDK from Android website.

  After downloading, go to the directory to which you downloaded the package to extract it

  $ chmod a+x android-ndk-r10e-linux-x86_64.bin

  $ ./android-ndk-r10e-linux-x86_64.bin

  Export ANDROID_NDK_HOME in ~/.bashrc $ vim ~/.bashrc

  export ANDROID_NDK_HOME=[/to/your/path]/android-ndk-r10e

  export PATH=$PATH:$ANDROID_NDK_HOME

• Prepare a Android device for test

Build and Run

You can change the compiler architecture in dlib-android/jni/Application.mk

Build executable files and shared library, and push the executable files to Android devices.

$ cd [$dlib-android]

Run a test daemon sample on your arm devices
$ python build_push.py --test true

Copy the shared lib to your Android project
$ python build_push.py --android_project dlib-android-appliciton/dlib/src/main/jniLibs/

You can build only (Optional)

$ ndk-build -j 2

You can also try to build the libraray and Android app together using Android stduio

Please refer to dlib-anroid-app

Write JNI and build shared library for Android Java application

There are examples in jnilib_ex

There is a sample app to demonstrate the result. dlib-android-app
