| /** |
| * Service interface linking the system with an eUICC local profile assistant (LPA) application. |
| * |
| * <p>An LPA consists of two separate components (which may both be implemented in the same APK): |
| * the LPA backend, and the LPA UI or LUI. |
| * |
| * <p>To implement the LPA backend, you must extend this class and declare this service in your |
| * manifest file. The service must require the |
| * {@link android.Manifest.permission#BIND_EUICC_SERVICE} permission and include an intent filter |
| * with the {@link #EUICC_SERVICE_INTERFACE} action. The priority of the intent filter must be set |
| * to a non-zero value in case multiple implementations are present on the device. For example: |
| * |
| * <pre>{@code |
| * <service android:name=".MyEuiccService" |
| * android:permission="android.permission.BIND_EUICC_SERVICE"> |
| * <intent-filter android:priority="100"> |
| * <action android:name="android.service.euicc.EuiccService" /> |
| * </intent-filter> |
| * </service> |
| * }</pre> |
| * |
| * <p>To implement the LUI, you must provide an activity for the following actions: |
| * |
| * <ul> |
| * <li>{@link #ACTION_MANAGE_EMBEDDED_SUBSCRIPTIONS} |
| * <li>{@link #ACTION_PROVISION_EMBEDDED_SUBSCRIPTION} |
| * </ul> |
| * |
| * <p>As with the service, each activity must require the |
| * {@link android.Manifest.permission#BIND_EUICC_SERVICE} permission. Each should have an intent |
| * filter with the appropriate action, the {@link #CATEGORY_EUICC_UI} category, and a non-zero |
| * priority. |
| * |
| * TODO(b/35851809): Make this a SystemApi. |
