I use the following code, to ask user for enabling scan always available
if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.JELLY_BEAN_MR2 && !wifiManager.isScanAlwaysAvailable)
startActivity(Intent(ACTION_REQUEST_SCAN_ALWAYS_AVAILABLE))
And it's works as it should, but on Samsung Galaxy Note 4 text in window appears as "null requests permission"

How to replace null with app name?
Why dont you try this instead of comparing version name try comparing the version number
private static final int REQUEST_SCAN_ALWAYS_AVAILABLE = any_number;
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (Build.VERSION.SDK_INT >= 18 && !wifiManager.isScanAlwaysAvailable()) {
startActivityForResult(new Intent(WifiManager.ACTION_REQUEST_SCAN_ALWAYS_AVAILABLE, REQUEST_SCAN_ALWAYS_AVAILABLE));
}
and for the resutl use below event
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == REQUEST_SCAN_ALWAYS_AVAILABLE)
{
// Make sure the request was successful
if (resultCode != RESULT_OK)
{
//User has not enabled the scan always available inform him to activate it
}
}
}
