Convert an email into link from text in PHP
$string = 'please contact me on email@emaildomain.com';
ereg_replace("[_A-Za-z0-9-]+(\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\.[A-Za-z0-9-]+)*(\.[A-Za-z]{2,3})", "<a href=\"mailto:\\0\">\\0</a>", $string);
ereg_replace is deprecated therefore we can use:
function convertEmailToLinks($string) {
return preg_replace("/[_A-Za-z0-9-]+(\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\.[A-Za-z0-9-]+)*(\.[A-Za-z]{2,3})/", "<a href=\"mailto:\\0\">\\0</a>", $string);

Bluetooth Low Energy
To check if your device support Bluetooth Low Energy programmically, check (getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)).
Android 4.3 (API Level 18) introduces built-in platform support for Bluetooth Low Energy in the central role and provides APIs that apps can use to discover devices, query for services, and read/write characteristics.
