4D for Mobile Tutorial – Your first application
The 4D mobile application generator allows you to create mobile applications for Android and iOS. In the documentation, you have several tutorials to help you get started and even go further with advanced apps.
The first example is simple and allows you to create a contact catalog. All the details can be found here.
And if you prefer, here are all the steps in the video:
Create your Native Mobile Application with 4D
4D for Android and 4D for iOS allow you to configure, design, build, and deploy native Android and/or iOS apps based on a 4D database. Once generated and deployed, mobile clients can connect to the 4D Server and interact with new or existing data without additional requirements.
4D for Android and 4D for iOS are included in a single integrated 4D component. You can create a mobile project and decide to build it for Android, iOS, or both.
4D handles the complexity and generates an Xcode project in Swift or an Android project in Kotlin. Then, you can reopen them with Xcode and Android Studio and continue to work on them.
This blog post is a compilation of features available in our mobile solution that enables you to build a complete app that goes all out!
A Tailor Made Native App: Place Orders with 4D for mobile
4D v19 R6 and v19 R7 brought two interesting features to 4D for Mobile. Sessions and displaying web pages served by the 4D server in your native mobile app. But did you think about the possibilities you get when combining them both?
This blog post will show you one of these possibilities. We are going to see how to build a simple app that enables mobile users to place orders with their central purchasing office to consolidate their stock:
Sections are Coming to 4D for Android
In a data list, the results are usually sorted on a relevant field to help the user find the desired data quickly and easily. Another trick to make the reading clearer is to group the results by adding sections.
Something that is possible since 4D v19 R8. Let’s delve into the details!
4D for Mobile: What’s New in 4D v19 R8
With every release, the list of 4D for iOS and 4D for Android features is growing bigger. And this feature release is no exception. Without further ado, let’s see what 4D v19 R8 has in store for you:
WHAT’S IN IT?
For 4D for Android (already available in 4D for iOS):
- Create a choice list from a table field or a JSON file.
- Use input control with code to retrieve, for example, GPS coordinates or phone numbers in the Contact application.
- Add a section in list form to group data by the company, for example.
- Use a custom login form.
- Improvement of the bottom navigation bar to display more than four tables and follow the Android guideline.
4D for Mobile : Get Mobile Users’ Cookies
As you probably know, scalable sessions have been available since 4D v18 R6. They’re a web session type that is able to handle several processes in preemptive mode. This means they can handle several user-agent requests simultaneously and share data between these processes.
Well, 4D v19 R7 greatly enhances this feature and makes it available to 4D for Mobile.
4D for Mobile : Display Web Pages in your Mobile Apps
You can already compose views based on templates; dozens of them are at your disposal to beautify your mobile apps. 4D v19 R7 is spicing up things even more by enabling you to display a web page served by 4D using a new preset action: Open URL.
This means four things :
- You are now totally free to create your own designs
- The user experience remains seamless embedded in your native app
- Get updated data in real-time
- You can keep user data and offer an optimized user experience using sessions.
You only have to create a web page optimized for mobile devices.
Let’s see how to use it with a simple example:
4D for Android: Say Hello to Material Design 3
To ensure that your application follows the latest design trends and that your users are blown away by a minimalistic, stylish, and great looking, we have updated the Material Design library.
4D for Mobile: What’s New in 4D v19 R7
With every release, the list of 4D for iOS and 4D for Android features is growing bigger. And this feature release is no exception. Without further ado, let’s see what 4D v19 R7 has in store for you:
WHAT’S IN IT?
- Sort the content of a list form for Android (already available in 4D for iOS)
- Update to Material Design 3 (for Android only)
4D for Mobile: Say Hello to Aliases
As you probably know, aliases have been available since 4D v19 R4. Aliases and computed attributes were a massive step forward for our development framework!
The days of defining business-related formulas in your 4D user interface are over; these concepts offer you a new way to separate your business logic from the UI, enabling you to improve performance by optimizing the parts separately.
And now, with 4D v19 R6, aliases are fully available and ready to use for scalars in your iOS and Android mobile projects as soon your aliases are defined on the 4D side.
