Using the app catalog application in WSO2 EMM you are able to check for applications that you or your organization made available in the WSO2 App Manager store, and install them on your device. The functionality of the app catalog is simillar to the Android play store. Let's take a look at how it functions.
How it works
The users must first install the app catalog application on the device from the App store:
https://<EMM_HOST>:<EMM_PORT>/store/
Once the app catalog is installed on the device it will directly call the services exposed by the WSO2 EMM Agent. The EMM agent will fetch the details of all the available applications, install or uninstall applications based on the request made by the app catalog.
- For more information on getting the application details via the REST API, see the WSO2 App Manager documentation on getting all the application details.
- For more information on installing or installing an application via the REST API, see the WSO2 App Manager documentation on installing and uninstalling an application.
The diagram given below will help you understand how the app catalog works in WSO2 EMM.
- After successfully installing the app catalog, you will access it to install / install applications or get the list of available applications. At that point it will automatically navigate to the WSO2 EMM agent's screen to list out all the available applications.
API for the application download status
The Android app catalog application provides an API for external applications to know the application download progress. To invoke this API, the external applications need to invoke the service exposed by the app catalog application and implement a BroadcastReceiver
to receive results.
Service name to be used when invoking : org.wso2.app.catalog.START_SERVICE
Action name to call API to receive a result : org.wso2.app.catalog.MESSAGE_PROCESSED
Operation code to be used when invoking : APP_DOWNLOAD_PROGRESS
Result intent parameters :
status : 200(success) or 400(failure).
payload : Result payload.
Service will return a JSON output as the payload
{
“app” : “APPLICATION PACKAGE NAME”,
“progress” “DOWNLOAD PROGRESS”
}
Given below is how to invoke the API by starting the service exposed.
public class CatalogServiceResponseReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { String status = intent.getStringExtra(“status”); JSONObject result = new JSONObject(intent.getStringExtra(“payload”)); //Your result manipulation code goes here } }
Context context = getApplicationContext(); IntentFilter filter = new IntentFilter(“org.wso2.app.catalog.MESSAGE_PROCESSED”); filter.addCategory(Intent.CATEGORY_DEFAULT); CatalogServiceResponseReceiver receiver = new CatalogServiceResponseReceiver(); registerReceiver(receiver, filter);
Intent intent = new Intent(“org.wso2.app.catalog.START_SERVICE”); Intent explicitIntent = createExplicitFromImplicitIntent(context, intent); if (explicitIntent != null) { intent = explicitIntent; } intent.putExtra("code", “APP_DOWNLOAD_PROGRESS”);
public static Intent createExplicitFromImplicitIntent(Context context, Intent implicitIntent) { //Retrieve all services that can match the given intent PackageManager pm = context.getPackageManager(); List<ResolveInfo> resolveInfo = pm.queryIntentServices(implicitIntent, 0); //Make sure only one match was found if (resolveInfo == null || resolveInfo.size() != 1) { return null; } //Get component info and create ComponentName ResolveInfo serviceInfo = resolveInfo.get(0); String packageName = serviceInfo.serviceInfo.packageName; String className = serviceInfo.serviceInfo.name; ComponentName component = new ComponentName(packageName, className); //Create a new intent. Use the old one for extras and such reuse Intent explicitIntent = new Intent(implicitIntent); //Set the component to be explicit explicitIntent.setComponent(component); return explicitIntent; }
