I think building the native library "liblo-native-code.so" from the
"core" git repo needs to be done from command line, not from Android
Studio; the README mentions

  Create an autogen.input file:

      --build=x86_64-unknown-linux-gnu
      --with-android-ndk=/home/$USER/Android/Sdk/ndk-bundle
      --with-android-sdk=/home/$USER/Android/Sdk
      --with-distro=LibreOfficeAndroid
      --enable-sal-log

  Run ./autogen.sh && make

In a later step, you can build the app from Android Studio.

Where is your "autogen.input" file located? It should be in the "core"
repo, not the "online" one and the above steps are meant to be run there.

While that should be unrelated to your build failure, there is meant to
be only one 'with-distro=...' parameter, since the latter will overwrite
the former otherwise. So you should just have one of those, depending on
whether you want to build for the ARM architecture
('--with-distro=LibreOfficeAndroid') or x86
('--with-distro=LibreOfficeAndroidX86').
