while installing facebook app...my tab showing error 24
You evidently had the app, uninstalled it, and now you're trying to reinstall it. But there's still some data left over from the old installation.
If you're rooted, look in /data/data for a folder with the package name (it's in the Play store URL) and delete the entire folder.
If you're not rooted, try using adb:
adb shell rm -R -f /data/data/<packagename>
(Without the <>, where packagename is the name of the package.)
Or go to Applications, press Play Store, clear cache, clear data.
