​​​Launcher Compatibility


Andr​oid Car Launcher Integration

For templated app​​s and services to be displayed to the headunit client, the headunit is required to update the Car Launcher with interfaces to Package Manager and Ignite Store. These APIs are used to determine which apps and services to display on the app grid, and what is the process for launching (Launch package name, Activity, and source selection).

In addition, App Tray integration covers for the App Store client needed as well​

Lau​ncher Customization to add App Icons for Media services: 


IGNITE3CI-541 -  ​Launcher icon for Media Open  :: As a user, I should see a icon for all media services on the app drawer that will launch the media player and select the media content provider as the source.

Instructions on how the Launcher can be customized by OEM such that media services can be shown as launch-able apps and starts car media template app with the launched app as selected source.​

Query for Media ​Servic​es to show in the app drawer

Below source code is a reference code to show how to query for Media Services

Get Media Services list and app info lik​e Label and Icon​

ResolveInfo mResolveInfo;
Context context = getContext();
if (context != null) {
    PackageManager packageManager = context.getPackageManager();
    if (packageManager != null) {
        List<ResolveInfo> mediaServices = packageManager.queryIntentServices(
                        new Intent(MediaBrowserService.SERVICE_INTERFACE),
        if(mediaServices != null && mediaServices.size() > 0) {
              items = new ArrayList<>(mediaServices.size());
              for (ResolveInfo info : mediaServices) {
					mResolveInfo = info;
					if(mResolveInfo != null && mResolveInfo.serviceInfo != null) {
						//Read media services apps label and icon that can be added to OEM specific launcher app grid/list adapter
						//Along with label and icon, have an indication to detect it as media service. This is needed to trigger media player intent once the icon is clicked from grid/list adapter
            			String appLabel= String.valueOf(mResolveInfo.serviceInfo.loadLabel(packageManager));
            			Drawable icon = mResolveInfo.serviceInfo.loadIcon(packageManager);

Intent to start Car Media app on selecting Media Services app icon

Intent to start car media app with selec​ted content provider as source​

When the launcher app icon is clicked​ and detected as media service app, use below intent to start car media app and select the media content provider as the source.

String packageName = mResolveInfo.serviceInfo.packageName;
String className = mResolveInfo.serviceInfo.name;
ComponentName componentName = new ComponentName(packageName, className);

Intent intent = new Intent("android.car.intent.action.MEDIA_TEMPLATE");
intent.putExtra("android.car.intent.extra.MEDIA_PACKAGE", componentName.getPackageName());
intent.putExtra("android.car.intent.extra.MEDIA_COMPONENT", componentName);

Services Shor​​​tcuts​

For serv​​ices distributed through Ignite, the launcher must support interfacing with the Ignite Store via Android Intents to display service content. The launcher must react to intents for adding and removing Ignite shortcuts on the App Grid UI.

L​auncher must subscribe to the broadcast intent:​

  <action android:name="android.content.pm.action.CONFIRM_PIN_SHORTCUT" />   

The Launcher must be updated with the following logic to add icons, labels, and perform the necessary Intent to Ignite Core Client

for (ShortcutInfo shortcut : shortcuts) {
    boolean igniteShortcut = false;

    // Create Intent
    igniteShortcut = shortcut.getExtras().getBoolean("IGNITE_SHORTCUT", false);
    if (shortcut.isEnabled() && igniteShortcut) {
        //Add icons to the app drawer
        //Add labels to the app drawer
