Geofences

Prerequisites

Before you can use this feature, you’ll need to integrate the Android Braze SDK. Additionally, you’ll need to set up silent push notifications.

Setting up geofences

Step 1: Update build.gradle

Add android-sdk-location to your app-level build.gradle. Also, add the Google Play Services location package using the Google Play Services setup guide:

1
2
3
4
dependencies {
  implementation "com.braze:android-sdk-location:+"
  implementation "com.google.android.gms:play-services-location:${PLAY_SERVICES_VERSION}"
}

Step 2: Update the manifest

Add boot, fine location, and background location permissions to your AndroidManifest.xml:

1
2
3
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

Add the Braze boot receiver to the application element of your AndroidManifest.xml:

1
2
3
4
5
<receiver android:name="com.braze.BrazeBootReceiver">
  <intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
  </intent-filter>
</receiver>

Step 3: Enable Braze location collection

If you have not yet enabled Braze location collection, update your braze.xml file to include com_braze_enable_location_collection and confirm its value is set to true:

1
<bool name="com_braze_enable_location_collection">true</bool>

Braze geofences are enabled if Braze location collection is enabled. If you would like to opt-out of our default location collection but still want to use geofences, it can be enabled selectively by setting the value of key com_braze_geofences_enabled to true in braze.xml, independently of the value of com_braze_enable_location_collection:

1
<bool name="com_braze_geofences_enabled">true</bool>

Step 4: Obtain location permissions from the end user

For Android M and higher versions, you must request location permissions from the end user before gathering location information or registering geofences.

Add the following call to notify Braze when a user grants the location permission to your app:

• java
• kotlin

1
Braze.getInstance(context).requestLocationInitialization();

1
Braze.getInstance(context).requestLocationInitialization()

This will cause the SDK to request geofences from Braze servers and initialize geofence tracking.

See RuntimePermissionUtils.java in our sample application for an example implementation.

• kotlin

    }

      if (grantResult != PackageManager.PERMISSION_GRANTED) {

        && PermissionUtils.hasPermission(applicationContext, Manifest.permission.ACCESS_FINE_LOCATION)
    if (!hasAllPermissions) {
      // Request both BACKGROUND and FINE location permissions
      requestPermissions(arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_BACKGROUND_LOCATION),
          RuntimePermissionUtils.DROIDBOY_PERMISSION_LOCATION)
    }
  } else {
    if (!PermissionUtils.hasPermission(applicationContext, Manifest.permission.ACCESS_FINE_LOCATION)) {
      // Request only FINE location permission
      requestPermissions(arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION),
          RuntimePermissionUtils.DROIDBOY_PERMISSION_LOCATION)
    }
  }
}

Step 5: Enable geofences on the dashboard

Android only allows up to 100 geofences to be stored for a given app. Braze locations products will use up to 20 geofence slots if available. To prevent accidental or unwanted disruption to other geofence-related functionality in your app, location geofences must be enabled for individual apps on the dashboard.

For Braze locations products to work correctly, confirm that your app is not using all available geofence spots.

Enable geofences from the locations page

Enable geofences from the settings page

Step 6: Manually request geofence updates (optional)

By default, Braze automatically retrieves the device’s location and requests geofences based on that collected location. However, you can manually provide a GPS coordinate that will be used to retrieve proximal Braze geofences instead. To manually request Braze Geofences, you must disable automatic Braze geofence requests and provide a GPS coordinate for requests.

Step 6.1: Disable automatic geofence requests

Automatic Braze geofence requests can be disabled in your braze.xml file by setting com_braze_automatic_geofence_requests_enabled to false:

1
<bool name="com_braze_automatic_geofence_requests_enabled">false</bool>

This can additionally be done at runtime via:

• java
• kotlin

1
2
3
BrazeConfig.Builder brazeConfigBuilder = new BrazeConfig.Builder()
    .setAutomaticGeofenceRequestsEnabled(false);
Braze.configure(getApplicationContext(), brazeConfigBuilder.build());

1
2
3
val brazeConfigBuilder = BrazeConfig.Builder()
    .setAutomaticGeofenceRequestsEnabled(false)
Braze.configure(applicationContext, brazeConfigBuilder.build())

Step 6.2: Manually request Braze geofence with GPS coordinate

Braze Geofences are manually requested via the requestGeofences() method:

• java
• kotlin

1
Braze.getInstance(getApplicationContext()).requestGeofences(latitude, longitude);

1
Braze.getInstance(applicationContext).requestGeofences(33.078947, -116.601356)

Enabling push-to-sync

Note that Braze syncs geofences to devices using background push. In most cases, this will involve no code changes, as this feature requires no further integration on the part of the app.

However, note that if your application is stopped, receiving a background push will launch it in the background and its Application.onCreate() method will be called. If you have a custom Application.onCreate() implementation, you should defer automatic server calls and any other actions you would not want to be triggered by background push.
