Cloning without the submodules:

git clone anyplace

Cloning with the submodules:

  • Submodules are separate git repositories within this one
  • You cal also fetch those at a later stage (with relevant git command)
  • Needed when developing libraries or the android client apps.
  • core-lib: clients/core/lib:
    • core library, written in kotlin
    • communicates to an Anyplace Backend service using Retrofit2
    • can be used to create more generic libraries
    • it is used by the android-lib to build the Android clients
  • android-lib: clients/android-new/lib-android:
    • most of the kotlin code is here
    • some thin clients are created out of this (SMAS, Navigator)
git clone anyplace --recurse-submodules

1. Server: [PLAY Framework]

2. Frontend apps:

  • Path: clients
  • Branch: develop-clients

3. Preface


Anyplace is a first-of-a-kind indoor information service offering GPS-less localization, navigation and search inside buildings using ordinary smartphones.

It is recommended to watch the video tutorials before proceeding with these instructions.

We hope that you find our Anyplace Indoor Information Service useful for your research and innovation activities. We would like to have feedback, comments, remarks, and, of course, any experience or test results from your own experimental setups. Currently, we can offer only limited support and assistance on the code, due to lack of resources, but we will try to get back to you as soon as possible. Questions and feedback may be sent to

If you install Anyplace on your own servers, please record your URL here.
