The error log is telling you what the problem is, and where it occurs:

12-15 03:49:51.714: E/AndroidRuntime(1115): java.lang.NullPointerException
12-15 03:49:51.714: E/AndroidRuntime(1115): at uk.co.flumeland.reversi.RevHighScoreAdapter.getView(RevHighScoreAdapter.java:68)

Step through with your debugger and you should see what is null and why.

Fix what? You still have not explained what the error is.

It is no use repeatedly posting the same data. I already explained that you need to use your debugger to trap where the error occurs and establish which variable is the null pointer, and what it is supposed to refer to.

thanks I will use debugger I sent information you

Look at line 68 of RevHighScoreAdapter.java.

"One man's wage rise is another man's price increase." - Harold Wilson

"Fireproof doesn't mean the fire will never come. It means when the fire comes that you will be able to withstand it." - Michael Simmons

"You can easily judge the character of a man by how he treats those who can do nothing for him." - James D. Miles

This is your error

12-15 03:49:51.124: I/HighScores(1115): getScores() called
12-15 03:49:51.154: I/HighScores(1115): getScores() no scores found

So because is not finding any scores, it is returning a null value that is not handled

12-15 03:49:51.714: E/AndroidRuntime(1115): at uk.co.flumeland.reversi.RevHighScoreAdapter.getView(RevHighScoreAdapter.java:68)

so just adding some error handling will fix your problem, easy
