Code Highlights

The above code snippet is for an Android activity that demonstrates how to receive asset tracking callbacks using the Asset Tracking SDK. The activity has the following main steps:

Initialize the Asset Tracking SDK.
Create an asset profile.
Bind the asset profile to the device.
Start tracking the asset.
Receive asset tracking callbacks.

The following is a description of each step:

To initialize the Asset Tracking SDK, the activity calls the initialize() method with your API key.
To create an asset profile, the activity creates an AssetProfile object and sets its properties. The AssetProfile object specifies the asset's custom ID, name, description, and attributes.
To bind the asset profile to the device, the activity calls the bindAsset() method with the asset ID.
To start tracking the asset, the activity calls the assetTrackingStart() method.
To receive asset tracking callbacks, the activity implements the AssetTrackingCallBack interface and overrides the following methods:
1. onLocationSuccess(): This method is called when the asset's location is updated.
2. onLocationFailure(): This method is called when the asset's location fails to be updated.
3. onTrackingStart(): This method is called when asset tracking is started.
4. onTrackingStop(): This method is called when asset tracking is stopped.

The activity also includes a few helper functions:

createAndBindAsset(): This function creates an asset profile, binds it to the device, and starts tracking the asset.
checkPermissionsAndStartTracking(): This function checks for location permissions and starts tracking the asset if they are granted.
showLocationServiceOffDialog(): This function shows a dialog to the user if location services are disabled.
