• Port dlib to Android platform

• You can build it to dynamic or static library for Android. You can also build dlib's sample to Android executable file.

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

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

• Download OpenCV android sdk https://sourceforge.net/projects/opencvlibrary/files/latest/download. Put contents of sdk native folder to third_party/opencv

• Download Android-NDK from Android website.

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

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

  export ANDROID_NDK_HOME=[NDK_PATH]/android-ndk-[version]

  export PATH=$PATH:$ANDROID_NDK_HOME

• Install Android Debug Bride (ADB). You can download it via Android SDK Manager or $ sudo apt-get install android-tools-adb

• Prepare an Android device for test

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

• The way to build the shared library for Android application

    $ cd [dlib-android]
    $ python build.py

Alternative way to build native code and copy to the Android Studio's project manually:

    $ cd [dlib-android]
    $ ndk-build -j 2
    $ cp -r libs/* androidstudio-examples/dlib-android-app/dlib/src/main/jniLibs

• Open Android Studio's projects in androidstudio-examples/dlib-android-app to run face detection, face landmark, and so on
