    <p>I am new to programming and I'm making a very simple blackjack game with only basic functions. When I run the program on the emulator it runs maybe for one hand, two, sometimes 5 or more but it always stops responding at some stage when i click on one of the three butons. There is a splash screen that runs for three seconds and the there is a thread comming from that activity that starts this menu activity. Could anyone maybe tell why this is happening? It usually happens when I clcik on one of the buttons even though there is no much comput</p> <pre><code>protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState);

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.
