Android: Set Bluetooth Discoverability Unbounded

Question

I have spent the last couple of days trying to make an app that keeps my Samsung Galaxy S3 mini (Android 2.1.4) discoverable for an \"infinite\" amount of time. My code look

Answer 1

above api level 14 EXTRA_DISCOVERABLE_DURATION 0 works with infinite limit but below this it works for max 1 hour.

This code works for me

Intent intent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
intent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 0);
startActivityForResult(intent, Utils.REQUEST_DEVICE_DISCOVERABLE);
