Using the app catalog application in WSO2 EMM you are able to check for applications that you or your organization Organization made available in the WSO2 App Manager store, and install them on your device. The functionality of the app catalog is simillar similar 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/

• 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 update 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.

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.
• 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” }

Invoking the API

Follow the steps given below to invoke the API by starting the exposed service.

...

Configure the BroadcastReceiver.

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. 

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.

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”);

Create an explicit intent method.
