Android Beacon Library

Build Status

An Android library providing APIs to interact with beacons. Please visit the project website for how to use this library.

IMPORTANT: By default, this library will only detect beacons meeting the AltBeacon specification.

If you want this library to work with proprietary or custom beacons, see the BeaconParser class.

What does this library do?

It allows Android devices to use beacons much like iOS devices do. An app can request to get notifications when one or more beacons appear or disappear. An app can also request to get a ranging update from one or more beacons at a frequency of approximately 1Hz.


The project website has full documentation including Javadocs.

Changes from the 0.x library version

This library has changed significantly from the 0.x library version and is now designed to work with open AltBeacons which fully support Android without any intellectual property restrictions. For more information on how to migrate projects using the 0.x APIs to the 2.x APIs, see API migration.



You may download binary releases here.


Add JCenter to your build file's list of repositories.

repositories {

to use the JCenter Repository

dependencies {
    implementation 'org.altbeacon:android-beacon-library:${altbeacon.version}'

replacing ${altbeacon.version} with the version you wish to use.
