i am new to Ibeacon and i want to know can we detect Ibeacon in android without using any SDKLibrary or library can any one give sample example.
i know some library like
There is a new small library: https://github.com/inthepocket/ibeacon-scanner-android
Without a library it's very easy to scan for ibeacons, you just need to create the correct ScanFilter, based on the iBeacon, and then start a BLE scan. Creating the correct ScanFilter can be hard at first, best have a look at the code in the mentioned library.
Dependant on Android version, location needs to be turned on, location permission needs to be granted and bluetooth, always, needs to be on.
