    <p>I am writing an Bluetooth game with blue tooth part based on android Bluetooth chat sample. And I have two phones to test. Here is the problem, when I connect one phone to the other, it sometimes shows the "Unable to connect device" bundle, but when I run the Bluetooth chat sample, it never shows this, so I think it is not the problem of device. Is there anyone who has studied the Bluetooth chat sample and has the same problem that would give me some help?</p> <p>I try to print the exception, it is like "java.io.IOException: Service discovery failed". And here is the code that cause the exception.</p> <pre><code>private class ConnectThread extends Thread { private final BluetoothSocket mmSocket; private final BluetoothDevice mmDevice; public ConnectThread(BluetoothDevice device) { mmDevice = device; BluetoothSocket tmp = null; // Get a BluetoothSocket for a connection with the // given BluetoothDevice try { tmp = device.createRfcommSocketToServiceRecord(MY_UUID); } catch (IOException e) { Log.e(TAG, "create() failed", e); } mmSocket = tmp; } public void run() { Log.i(TAG, "BEGIN mConnectThread"); setName("ConnectThread"); // Always cancel discovery because it will slow down a connection mAdapter.cancelDiscovery(); // Make a connection to the BluetoothSocket try { // This is a blocking call and will only return on a // successful connection or an exception mmSocket.connect(); } catch (IOException e) { Log.e("error", e.toString()); connectionFailed(); // Close the socket try { mmSocket.close(); } catch (IOException e2) { Log.e(TAG, "unable to close() socket during connection failure", e2); } // Start the service over to restart listening mode BluetoothChatService.this.start(); return; } // Reset the ConnectThread because we're done synchronized (BluetoothChatService.this) { mConnectThread = null; } // Start the connected thread connected(mmSocket, mmDevice); } public void cancel() { try { mmSocket.close(); } catch (IOException e) { Log.e(TAG, "close() of connect socket failed", e); } } } </code></pre> <p>The exact position is<br> <code>mmSocket.connect();</code></p>

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.
