For some time, you’ve been able to create your own custom data formatters and convert strings, booleans, or integers to images in your generated app.
This new 4D v19 R2 feature will allow you to take full advantage of those formatters for iOS and Android, and make sure images look good in both light and dark appearances.
Let’s see how!
That also includes a crucial step: choosing a main color for the app. That’s why, since the introduction of 4D for iOS, the main color of your mobile application was defined by the dominant color of your application’s logo.
With 4D v19 R2, we’re giving you a feature that lets you easily define the main color of your iOS and Android app, by selecting it from a color picker fully integrated into the project editor.
For a few weeks, you’ve been able to use the offline action feature, and we’ve already obtained great feedback about it.
As we’re constantly improving the product’s features set, application users can edit and retry sending pending tasks that failed due to server validation. Let’s see how it works.
We are pleased to announce that 4D for Android is available with 4D v19 R2.
Many features are already available, and with each new release, we’ll enrich the possibilities so that 4D for Android’s features match those of 4D for iOS.
What’s best is that the same mobile project can generate both native iOS and native Android apps. We made sure to provide very similar user experiences on both platforms while still respecting their standards.
how to extend your application and go mobile
The mobile project editor is fully integrated into 4D. You can design and build native iOS and Android apps quickly and easily without programming. If you want to go further, you can open the generated application with Android Studio or Xcode and customize it with Kotlin or Swift.
The other big advantage of a native application is that you can access the data even when you’re offline.
As app users, we don’t pay much attention to the sophisticated authentication technologies that secure our applications. But they are essential to help prevent malicious people from usurping our identity. That’s why the authentication process that is included in 4D for iOS is so important to us. But many 4D for iOS users have been asking for more, and specifically, for new modern ways to login.
The new SignInWithQRCode login form template lets users log into their apps by scanning QRCode, and grants access directly to already authenticated users.
In a previous blog post, we announced the launch of 4D for Android. But how to build, visualize and play with your Android app on your favorite virtual device? This blog post covers all these questions with answers and concrete examples.
Nowadays, mobile users expect apps to work even when they’re offline. Otherwise, a poor network connection can give a poor user experience. Offline mode is no longer just an extra feature you can choose to add to your app, it’s something many users expect, especially for delivery apps with GPS navigation, apps for urgent medical assistance, construction businesses, and banking apps.
As you may already know, since v17 R2, 4D for iOS already allows users of the application to view data offline. But something was missing.
What about offline tasks?
Are you new to 4D for iOS? New to our no-code native app builder that allows you to extend your existing 4D business applications to mobile devices? Or maybe you just need a jumpstart to see how far the product allows you to go?
If this is the case, check out what 4D for iOS can do thanks to its feature set, and watch this video to witness the building of a mobile app in less than two minutes:
As of 4D v18 R4, you can send notifications to your application users. Now with 4D v18 R6, you can start data synchronization with a push notification.
This could be useful, for example, in the case of delivery tracking applications. First, the delivery information is updated in the database, then a notification is sent to the customer. The notification contains a request to synchronize the data, so when the customer consults the record on their smartphone, the data is up to date.
4D for iOS already lets you take advantage of your database relations to create dynamic and complex apps.
But many of our 4D for iOS developers have asked for more, and once again 4D listened! 4D v18 R6 includes splendid features for relation interactions.
Let’s delve into the details!
