Can't find model-distance-calculations.json

@jessolo, you are correct about the code flaw above but also that it is not causing the stack trace you mention.

I wonder if there is something special about your setup that is causing it to not find that file. Are you using the aar file with Android Studio (if so what version?) or the tar.gz file imported as an Android Library Project in Eclipse?

[jessolo]

I am using the whole project as a library project. Converted from gradle to ant. I am not using the tar or the aar file. I am having the file in the assets folder. So it does not read from assets. If it loads from web and stores into the data directory, it does not read from the path.

[davidgyoung]

This sounds contradictory: "I am having the file in the assets folder. So it does not read from assets." can you please explain? The code is throwing an exception because it cannot find the built-in json file.

[jessolo]

As per the loading flow

1. It tries to load from File from the path /data/data.... It does not find it, so throws a Runtime exception -- App Crashes. Moving to assets was a workaround. But it will not work.I am now not having the file from assets. When RuntimeException is thrown beacon service does not startup.It does not try to load from web.

@jessolo, understand that by repackaging the library and making the model-distance-calculations.json file not available on the classpath, you are using the library in a non-standard way. It is this repackaging that is causing the problem.

That said, I have made some changes on the following branch that may allow you to use the library in this non-standard manner. Please give it a try and let me know if it helps:

If this solves your problem, I will test in a standard configuration and then merge this onto master.

[jessolo]

This seems to be working in my case. Looks good. The RuntimeException is the one which created the issue. Pls merge it to the master.

merged to master

@davidgyoung Can you repost the link to your proposed changes? That link doesn't work anymore.
