    <p>Are you using a library, or is BTDiscoverable() a function you made?</p> <p>In Android, the discoverability is set using an intent </p> <pre><code>Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300); startActivity(discoverableIntent); </code></pre> <p>(see <a href="http://developer.android.com/guide/topics/connectivity/bluetooth.html#EnablingDiscoverability" rel="nofollow noreferrer">http://developer.android.com/guide/topics/connectivity/bluetooth.html#EnablingDiscoverability</a>)</p> <p>So if I understand you correctly, what you could do is: launch this intent (or use your BTDiscoverable if it is equivalent), then return. The button remains enabled. If the user accepted the discoverability, next time he/she will push the button, the code will execute the else loop and start the server, otherwise it will ask the permission again</p> <pre><code>public void onClick(View v) { Button bttn = (Button) v; if(bttn.getId() == R.id.bt_server_start) { /* * If BluetoothAdapter name does not start with BT_ prefix, add it to the name, then proceed */ if (!mBluetoothAdapter.getName().startsWith(PREFIX)) mBluetoothAdapter.setName(PREFIX + mBluetoothAdapter.getName()); /* * Check the connectability/discoverability, compare to the statemanet made by user that it is enabled. * If they are not equal, run BTDiscoverable method - set device to be discoverable by other devices */ if(mBluetoothAdapter.getScanMode() != BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE) { (If your BTDiscoverable is this equivalent if this, you can use it) Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300); startActivity(discoverableIntent); } else { /* * As the bluetooth is now on and the device can be connected/discovered, USER MUST START THE SERVER SITE ON DEVICE BY * CREATING NEW THREAD */ DeviceServer = new AcceptThread(); /* * Start the thread */ DeviceServer.start(); /* * Set the availability of the button */ bttn.setEnabled(false); ((Button) this.findViewById(R.id.bt_server_stop)).setEnabled(true); } } else if (bttn.getId() == R.id.bt_server_stop) { DeviceServer.cancel(); bttn.setEnabled(false); ((Button) this.findViewById(R.id.bt_server_start)).setEnabled(true); BTDeviceName(); } } </code></pre> <p>If you really want the button to be disabled immediately when the user chooses "yes", then you should try to launch this intent using startActivityForResult(disoverableIntent). Then the onActivityResult function (you can override it in your activity) will be called and you should be able to see here if the user accepted the discoverability or not. So you would get something like:</p> <pre><code>@override protected void onActivityResult(int code, int result, Intent intent) { if(result == 1) // Here i'm not sure how to check that the user accepted the discoverability /* * As the bluetooth is now on and the device can be connected/discovered, USER MUST START THE SERVER SITE ON DEVICE BY * CREATING NEW THREAD */ DeviceServer = new AcceptThread(); /* * Start the thread */ DeviceServer.start(); /* * Set the availability of the button */ bttn.setEnabled(false); ((Button) this.findViewById(R.id.bt_server_stop)).setEnabled(true); } </code></pre>

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.
