Get started

  • Before using the Nearby Connections API, install the Google Play Services SDK and review the provided code samples.

  • Apps using Nearby Connections must request specific permissions in the AndroidManifest.xml to function correctly.

  • Several permissions, like location and Bluetooth access, require runtime requests due to their sensitive nature.

  • The Nearby Connections API will not function if the user denies necessary permissions for advertising or discovery.

Before you begin

Before you start to code using the Nearby Connections API:

Request permissions

Before using Nearby Connections, your app must request the appropriate permissions. Add the following permissions to your AndroidManifest.xml:

<!-- Required for Nearby Connections -->
<uses-permission android:maxSdkVersion="31" android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:maxSdkVersion="31" android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:maxSdkVersion="30" android:name="android.permission.BLUETOOTH" />
<uses-permission android:maxSdkVersion="30" android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:maxSdkVersion="28" android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:minSdkVersion="29" android:maxSdkVersion="31" android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:minSdkVersion="31" android:name="android.permission.BLUETOOTH_ADVERTISE" />
<uses-permission android:minSdkVersion="31" android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:minSdkVersion="31" android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:minSdkVersion="32" android:name="android.permission.NEARBY_WIFI_DEVICES" />
<!-- Optional: only required for FILE payloads -->
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

Since ACCESS_FINE_LOCATION, BLUETOOTH_ADVERTISE, BLUETOOTH_CONNECT, BLUETOOTH_SCAN and READ_EXTERNAL_STORAGE are considered to be dangerous system permissions, in addition to adding them to your manifest, you must request these permissions at runtime, as described in Requesting Permissions.

If the user does not grant all required permissions, the Nearby Connections API will refuse to allow your app to start advertising or discovering.
