I don't know if there're any graphical browsers available. But what definitely works is watching the entries by using the console. So just connect to your emulator by running "adb shell" in your console (that's the command for Windows, but Linux shouldn't vary that much). After being automatically logged on run the command "sqlite3 /data/data/com.google.android.providers.contacts/databases/contacts.db" for getting the contact entries for example.
You can find out the names of the available databases by browsing through the directories. So under "/data/data/" the databases are stored. To find out the tables names open the ".db" files with "cat [filename]" to get the content in a more or less readable format.
It's not a comfortalbe method, but it works. If anybody knows another way, just say it!
