WebRTC sample for media demo crashing when building on windows 7

[shyam sundar kulkarni]

Hello All,

I was searching for android samples which had only media transmission and found out this relevant.

**What steps will reproduce the problem?**  

1. Take Media demo sample from (http://webrtc.googlecode.com/svn/trunk/webrtc/examples/android/media_demo/)

2. take videoengine sample from

(https://code.google.com/p/webrtc/source/browse/trunk/src/modules/video_render/main/source/android/java/org/webrtc/videoengine/?r=2163)

3. Club all these in an Android application project on windows 7, build it will get Webrtcdemo.apk

**What is the expected result?**  

App should launch perfectly.

**What do you see instead?**  

App crashes at the startup stating "**Unfortunately WebRTC Engine Demo has stopped**"

**What version of the product are you using? On what operating system?**  

- OS: Windows 7, 64 Bit  

- Eclipse (adt-bundle)  

- ADT (adt-bundle-windows-x86_64-20131030)  

**Please provide any additional information below.**
