Migration to IoTivity-lite ( e6ba0bb ) App never leaves SplashActivity

[fercamp09]

Hello, I am trying to run the App at the commit Migration to IoTivity-lite ( e6ba0bb ), but I have encountered some issues:

1. Cannot open a library at 'FileMapping(from=.../otgc/src/main/jniLibs/iotivity-lite.jar): I solved this by

# Updating the iotivity-lite submodule
$ cd otgc-android/extlibs/
$ git submodule init
$ git submodule update
$ cd iotivity-lite
$ git submodule init
$ git submodule update

# Install a standalone toolchain of the ndk
$ cd ~/Android/Sdk/ndk-bundle/build/tools
$ ./make_standalone_toolchain.py --arch arm --api 23 --install-dir ~/android-arm-23

# Build iotivity-lite.jar using the standalone toolchain
$ cd port/android
$ make NDK_HOME=~/android-arm-23/  ANDROID_API=23

# Copy the generated files to the android project under the jniLibs folder(otgc)
$ mkdir ~/Documents/otgc-android/otgc/src/main/jniLibs/
$ mkdir ~/Documents/otgc-android/otgc/src/main/jniLibs/armeabi-v7a/
$ cp ~/otgc-android/extlibs/iotivity-lite/swig/iotivity-lite-java/libs/libiotivity-lite-jni.so ~/otgc-android/otgc/src/main/jniLibs/armeabi/
$ cp ~/otgc-android/extlibs/iotivity-lite/swig/iotivity-lite-java/libs/iotivity-lite.jar ~/otgc-android/otgc/src/main/jniLibs/

2. Now it compiles and runs, but stays in the Splash indefinitely. I am not sure if I am doing something wrong or if I am missing something. I tried compiling iotivity-lite for various architecture (arm64, x86_64) but only arm works, so I use it. I would like to know how can I make it work.
