Hi John,

I've updated your project to use gradle and added the ability to set the replay delay between GPS points.

It would be great to merge this work back into your core project. Would you consider a pull request on this? It will modify your directory structure totally but the core project is still there.

That's it.

Any recommendations on modifying the code to loop forever for all points in the gpx file? I have a 30 minute capture or so and it's better irritating restarting it while running my tests

Problem:

Currently Android-GPX-Mock-Location-Provider cannot be made available in f-droid appstore because it uses a project local lib libs/xstream-android.jar to parse/read gpx files.

f-droid policy does not allow to reference project local libs/jars. it requires either source code integration in a sub-project or the lib must be available from a public maven repository (i.e. jcenter, mavencentral)

Possible solution

Replace xstream-android based gpx parser with k3b-geoHelper-s parser that supports reading different geo-formats: gpx-1.0, gpx-1.1, kml, non xml geo-uri. As a side effect Android-GPX-Mock-Location-Provider can use any supported format as data source.

To implement you can use

• Eventbased with xml formats GpxReaderBase with onGeoInfo(IGeoPointInfo geo)
• Array based with xml formats List GpxReader:getTracks(stream)
• Array based with in memory string (xml or geo-uris): List GeoXmlOrTextParser:get(String stringWithXmlOrText)

Usage with gradle

dependencies {
	compile 'com.github.k3b:k3b-geoHelper:v1.1.5'
}

k3b-geoHelper is an opensource java lib under appache license

import com.vividsolutions.jts.geom.Coordinate;
^ The import com.vividsolutions cannot be resolved

Thank you for this library. I've taken huge inspiration from it in my project.

However I think there is issue with
https://github.com/johncarpenter/Android-GPX-Mock-Location-Provider/blob/master/android/app/src/main/java/com/twolinessoftware/android/framework/service/comms/gpx/GpxSaxParser.java#L80

According to https://stackoverflow.com/questions/4567636/java-sax-parser-split-calls-to-characters

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.

Meaning parser in some circumstances will return only chunks of data (value).

Fix would be as in comment suggested https://stackoverflow.com/a/18574473/3896616
