Indoor Atlas: Cant get Android SDK example to run

I just downloaded the Indoor Atlas SDK and attempted to run. There were various small errors that I managed to fix but now stuck. The app installs (via emulator and on a Galaxy tab) but both giving me the same error:

E/AndroidRuntime﹕ FATAL EXCEPTION: IdaSensorReadingManager
    Process: xxxx.indooratlas, PID: 1632
    java.lang.NullPointerException: Attempt to invoke virtual method 'int android.hardware.Sensor.getType()' on a null object reference
            at com.indooratlas._internal.ai.a(Unknown Source)
            at com.indooratlas._internal.ai.b(Unknown Source)
            at com.indooratlas._internal.ai$a.handleMessage(Unknown Source)

            at android.os.Looper.loop(Looper.java:135)
            at android.os.HandlerThread.run(HandlerThread.java:61)

Is this standard Android error or Indoor Atlas specific?

Solution

  • You currently (with version 1.3.1) cannot run IndoorAtlas's Android SDK using an emulator. IndoorAtlas's technology is mostly based on magnetic positioning (i.e. using magnetic field sensor and fusing other sensors too). You might be able to run the SDK but unless you manage to simulate those sensors in your emulator, you would not get too far as you would not get any locations. See key features of IndoorAtlas's service: https://www.indooratlas.com/features. There are some projects for simulating sensors, such as this: https://code.google.com/p/android-sensor-emulation/ - but I'd recommend using a real device if possible. Note that in order to do a full positioning test, you also need to create a magnetic map of your location (unless there is an already mapped public location nearby), see developer website on instructions how to get it done: https://developer.indooratlas.com/dashboard (Collect Data).
