Body
Android's Bluetooth may still have some glitches, however, in this case you wrote about the remote BT-Device: <blockquote> It always initiates the connection, and will refuse incoming connections. </blockquote> In your code snippet, you try just what should not work: Initiate a connection from the Android device to the remote device. <blockquote> I now detect incoming connection attempts and then start the connect() </blockquote> This is almost certainly the completely wrong approach - and, actually, it should not work at all. If it does intermittently on some devices this is more of a bug in those devices than an undocumented feature. So, when dealing with incoming Bluetooth connections on Android, use the listening server approach described e.g. in: <a href="http://developer.android.com/guide/topics/wireless/bluetooth.html#ConnectingAsAServer" rel="nofollow">http://developer.android.com/guide/topics/wireless/bluetooth.html#ConnectingAsAServer</a> using <a href="http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html#listenUsingRfcommWithServiceRecord%28java.lang.String,%20java.util.UUID%29" rel="nofollow">listenUsingRfcommWithServiceRecord()</a>. As for the pairing on Android devices: Pairing should be necessary only once for each remote device. Once the device is paired, Android stores the pairing information and will allow future connections without prompting for a PIN for pairing again.

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.
