JarCastingSmartcar Android Auth SDK 
The SmartcarAuth Android SDK makes it easy to integrate with Smartcar Connect from Android.
Reference Documentation
Installation
Add the following to your application's build.gradle dependencies:
dependencies {
implementation 'com.smartcar.sdk:smartcar-auth:3.0.0'
implementation 'androidx.browser:browser:1.0.0'
}
Redirect URI Setup
Your application must register a custom URI scheme in order to receive Connect's response. Smartcar requires the custom URI scheme to be in the format of "sc" + clientId + "://" + hostname. This URI must also be registered in Smartcar's developer portal for your application. You may append an optional path component or TLD. For example, a redirect uri could be:
sc4a1b01e5-0497-417c-a30e-6df6ba33ba46://myapp.com/callback
You will then need to register the URI in the AndroidManifest.xml by inserting a new activity with an intent filter. More information on the data element.
<activity android:name="com.smartcar.sdk.SmartcarCodeReceiver">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="sc4a1b01e5-0497-417c-a30e-6df6ba33ba46"
android:host="myapp.com"
android:path="/callback" />
</intent-filter>
</activity>
Usage
- Instantiate a new
SmartcarAuthinstance with aSmartcarCallbackhandler:
import com.smartcar.sdk.SmartcarAuth;
import com.smartcar.sdk.SmartcarCallback;
import com.smartcar.sdk.SmartcarResponse;
SmartcarAuth smartcarAuth = new SmartcarAuth(
"your-client-id",
"your-redirect-uri",
new String[] {"read_vehicle_info", "read_odometer"},
// Create a callback to handle the redirect response
new SmartcarCallback() {
@Override
public void handleResponse(SmartcarResponse smartcarResponse) {
// Retrieve the authorization code
Log.d("SmartcarAuth", "Authorization code: " + smartcarResponse.getCode());
}
});
- Launch the Smartcar Connect flow:
smartcarAuth.launchAuthFlow(getApplicationContext());
Alternatively, add a click handler to any view to launch the Smartcar Connect flow.
Button connectButton = findViewById(R.id.connect_button);
smartcarAuth.addClickHandler(getApplicationContext(), connectButton);
- Use the
AuthUrlBuilderfor additional configuration:
String authUrl = smartcarAuth.authUrlBuilder()
.setState("foo")
.setForcePrompt(true)
.setMakeBypass("TESLA")
.build();
// Launch Smartcar Connect with the configured parameters
smartcarAuth.launchAuthFlow(getApplicationContext(), authUrl);
// Alternatively attach a click handler
Button connectButton = findViewById(R.id.connect_button);
smartcarAuth.addClickHandler(getApplicationContext(), button, authUrl);
