(I tried refreshing and cleaning the project)</p> <p>Your help is really appreciated - im stuck!</p>

    1. COThat's odd... try Build -> Clean from the Eclipse menu, and make sure your class files are actually in the same project as your Manifest and in the src/org/anselm/eickhoff/rhythm folder, for starters. Can you import and run any of the sample projects that ship with the SDK in Eclipse?

    2. COI cleaned the project, the samples work and this used to work too, but I renamed RhythmGame to RhythmGameActivity and that broke it. (see updated question)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
