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.
Info - 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.

Invoking the application download status API
The Android app catalog application provides an API for external applications to know the get notified of an 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.
...
Guidelines
Use the points given below as guidelines:
- Use the
org.wso2.app.catalog.START_SERVICE
...
- service name to
...
- invoke the API.
- Use the
org.wso2.app.catalog.MESSAGE_PROCESSED
...
- action name to call and receive the output from the API.
- Use the
APP_DOWNLOAD_PROGRESS
...
- operation code when invoking the API.
- Define the result intent parameters
...
- .
status : 200(success) or 400(failure).
payload : Result payload.
...
- Define 200 as the status codes to denote success and 400 to denote failure.
Define the payload as the result payload. The service will return the JSON output as the payload
Code Block
{
“app” : “APPLICATION PACKAGE NAME”,
“progress” “DOWNLOAD PROGRESS”
}
...
{ “app” : “APPLICATION PACKAGE NAME”, “progress” “DOWNLOAD PROGRESS” }
Invoking the API
Follow the steps given below to invoke the API by starting the exposed service exposed.
Configure the
BroadcastReceiver
.Code Block language java
...
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 } }
...
Register a receiver
...
so that it listens to the service results.
...

java 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);
...
Call the service
...
. This should always happen

after registering the receiver

...
Create an explicit intent method.
Code Block language java
...
...
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; }
