Exception when building and running ReconSDKApplication

[mga...@cogsimtech.com]

All,

I'm an experienced developer (C++/C#) but am new to Java, Android and the Mod Live platform.

When I follow the instructions on the Mod Live developer website to use "adb install ..." to install the downloadable (i.e., pre-built) "ReconSDKApplication.apk", the demo application runs fine.  However, when I import the source code into eclipse, build, install and run my locally generated "ReconSDKApplication.apk", I encounter an exception:

Any suggestions?  Any and all help is appreciated.  

We're really excited at the prospect of writing software for the Mod Live HUD.

Thanks!

Anyone?

I had no problem when I imported the project to eclipse and ran it.

It must be .jar file import issue.

You can try clean build. And remove ReconSDK.jar from the build path ( Right Click on the Project -> Properties -> Java Build Path -> Libraries )

and then from the Package Explorer ( on the Left Panel ) find /libs folder and right click on the ReconSDK.jar file -> Build Path -> Add to Build Path

And tell us what happened.

Also there is a lot of resource about this particular issue on Google + StackOverflow.

Occasionally I face this issue too. Good luck with it.

add the jar manually under project/properties, etc

 

did the same with me.
