Implement Deep Linking to Another App from an MDK App

In the MDK editor, you will create 4 new JavaScript files:

• OpenSAPMobileCards.js to open SAP Mobile Cards app
• OpenSAPFioriClient.js to open SAP Fiori Client app
• OpenUI5.js to open an UI5 app running in SAP Fiori Client app
• OpenSAPcom.js to open SAP.com web page

You can find more details about writing a Rule.

Right click on the Rules folder | New | File.

Enter the file name OpenSAPMobileCards.js, click OK.

Copy and paste the following code.

export default function openurl(clientAPI) {
// Get the Nativescript UI Dialogs Module
const dialogs = clientAPI.nativescript.uiDialogsModule;
// Get the Nativescript Utils Module
const utilsModule = clientAPI.nativescript.utilsModule;
return dialogs.confirm("Do you want to leave the current app?").then((result) => {
    if (result === true) {
        //This will open SAP Mobile Cards app
   return utilsModule.openUrl("com.sap.content2go://").then(	                
            (success) => Promise.resolve(success),
            (failure) => Promise.reject('The requested app or page is not available ' + failure));
    } else {
        return Promise.reject('User Deferred');
    }
});
}

openUrl is a NativeScript API to open an URL on device. You can find more details about this API.

Repeat the above step and create another new file:

Enter the file name OpenSAPFioriClient.js, click OK.

Copy and paste the following code.

export default function openurl(clientAPI) {
// Get the Nativescript UI Dialogs Module
const dialogs = clientAPI.nativescript.uiDialogsModule;
// Get the Nativescript Utils Module
const utilsModule = clientAPI.nativescript.utilsModule;
return dialogs.confirm("Do you want to leave the current app?").then((result) => {
    if (result === true) {
        //This will open SAP Fiori Client App
    return utilsModule.openUrl("com.sap.fiori.client.xcallbackurl://x-callback-url").then(               
            (success) => Promise.resolve(success),
            (failure) => Promise.reject('The requested app or page is not available ' + failure));
    } else {
        return Promise.reject('User Deferred');
    }
});
}

Repeat the above step and create another new file:

Enter the file name OpenUI5.js, click OK.

Copy and paste the following code.

export default function openurl(clientAPI) {
// Get the Nativescript UI Dialogs Module
const dialogs = clientAPI.nativescript.uiDialogsModule;
// Get the Nativescript Utils Module
const utilsModule = clientAPI.nativescript.utilsModule;
return dialogs.confirm("Do you want to leave the current app?").then((result) => {
    if (result === true) {
        //This will open Software Downloads app running in SAP Fiori Client
return utilsModule.openUrl("com.sap.fiori.client.xcallbackurl://x-callback-url/openFioriUrl?url=https://launchpad.support.sap.com/#/softwarecenter").then(                  
            (success) => Promise.resolve(success),
            (failure) => Promise.reject('The requested app or page is not available ' + failure));
    } else {
        return Promise.reject('User Deferred');
    }
});
}

Create one more file and name it to OpenSAPcom.js.

Copy and paste the following code.

export default function openurl(clientAPI) {
// Get the Nativescript UI Dialogs Module
const dialogs = clientAPI.nativescript.uiDialogsModule;
// Get the Nativescript Utils Module
const utilsModule = clientAPI.nativescript.utilsModule;
return dialogs.confirm("Do you want to leave the current app?").then((result) => {
    if (result === true) {
        //This will open SAP.com website
return utilsModule.openUrl("https://www.sap.com").then( 	                
            (success) => Promise.resolve(success),
            (failure) => Promise.reject('The requested app or page is not available ' + failure));
    } else {
        return Promise.reject('User Deferred');
    }
});
}

Save the changes.
