    Guys, I can confirm that the plugin that H-ALEX made now works. I suggest you get it while we wait for Unity:

    Thanks again!

    @EMPEROR : I looked at your files and I guess the problem was due to the faulty directory structure I made to store the jar file. Please try the new unitypackage and give us your feedback. Cheers.

    Thanks for the reply and your time @H-ALEX. I made a new project with just the plugin but I still get an error when running the sample. I've ran it on an android emulator(genymotion) and on a xperia z2 but both display the error below.

    @SIMONALKEMADE2 the plugin is android only because this issue is android only. I've not experienced a similar bug with iOS.

    Hello @EMPEROR, I don't see exactly why you have this error. Just to let you know that you cannot call directly LocationOverride, please use InputLocation instead. Also you have to keep the original directory structure of the plugin. And finally you don't have to add a manifest at all, Unity does it automatically because of line 45 of LocationOverride.cs (which is never called, and here to trick Unity to let him think we're using GPS code).

    If you have a custom manifest, you'll need :
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <!-- Needed only if your app targets Android 5.0 (API level 21) or higher. -->
    <uses-feature android:name="android.hardware.location.gps" />

    Please send me an email at the adress on the webpage with your sources if I can help.
    Also please test the plugin in an empty project before to confirm and narrow your problem down.

    H-ALEX thank you for the plugin. I get a Null reference exception at locationoverride.cs line 62 when running the sample. I'm thinking my manifest file I created is wrong; would you mind sharing the manifest that you use?

    H-ALEX thank you for the android workaround but I just tested it on iOS and it seems it doesn't find GPS on iOS as well so iOS needs to be fixed as well. My Objective-C sucks so I will try to look into it but don't expect too much.
