Error on onResume and onPause

For some reason eclipse is giving me an error on both the onResume and onPause lines, saying that an @ is expected, even though both lines were preceded with the @Override.

The screenshot: http://tinypic.com/r/33eskf5/8

I may have mis-typed something; but I cannot locate any typos.

Thanks!

In the picture you are missing an @Override before onResume. I would add it, and then Clean and Build (located under project at the top of the screen).

Thanks Theodore,

I did try that - I have been adding and removing the @Override statements to see if maybe removing them would help.

I did the clean and build, unfortunately no change.

Here is the error with both Override statements in place. http://tinypic.com/r/ehaerr/8

Do you mind copying and pasting all of the code from MainActivity.java? My next idea would be to delete onResume and let content assist create a new one and see if it is getting the area by default.

Also wondering if maybe you have it inside a set of brackets that it shouldn't be.
