    <p>Move <code>GetPairedDevices();</code> into your <code>onActivityResult()</code></p> <p>Somthing like</p> <pre><code> @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub //super.onActivityResult(requestCode, resultCode, data); if (resultCode == RESULT_CANCELED){ Toast.makeText(getApplicationContext(), "too bad..", Toast.LENGTH_LONG).show(); finish(); } else if (resultCode == RESULT_OK) { GetPairedDevices(); } </code></pre> <p>this way <code>onCreate()</code> can finish and that function will only run if you enable bluetooth, which I believe is what you want</p> <p>If you want it to run if Bluetooth is enabled and not <code>null</code> in <code>onCreate()</code> then you may want to change your <code>onCreate()</code> to something like</p> <pre><code> @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); init(); if (BtAdapter==null){ Toast.makeText(getApplicationContext(), "No Bluetooth adapter...",0 ).show(); finish(); } elseif (BtAdapter != null &amp;&amp; !BtAdapter.isEnabled()){ Intent intent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); startActivityForResult(intent, 1); } else{ GetPairedDevices(); } } </code></pre> <p><strong>Note:</strong></p> <p>This was just a quick example of how you need to do it because <code>onCreate()</code> is going to finish executing the remaining code in the function. I haven't tested it or know all of your code but something like this should help.</p>

    1. COyes, you probable right, but i have plans to write more code into onCreate activity, like open sockets and so on... I just have to be sure that subactivty is finished before continuing with other operations...

    2. COThen you should put them in `onActivityForResult()` or move them to the last `else` as in my example

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).
