Issue
I have existing project in Eclipse for Android that all still run with no issues.
It's been a while since I have been on Android and I created a new one from scratch. However, it crashes when testing to a phone (Samsung s3) and I can't figure out why. All the settings seem just the same as my other projects that still work. I get a Source Not Found error. Tried many suggestions on here without luck.
Maybe it's a case of I haven't done enough as I have done the bare minimum. Project tree, manifest, java class and xml below:

Solution
You can see in my first screenshot that I had "mcsapp" package name under "src". When looking at the logcat error it was stating it couldn't find said class under "com.mcsapp", so I created a new package named "com.mcsapp" and moved my class into it.
Problem solved.
