The AppStudio Framework, or AppFramework, contains platform-neutral QML components to allow you to create apps that work across multiple platforms. The components that the AppFramework provides are intended for use in providing base functionality for your app, including managing file paths, networking interfaces, and image manipulation, as well as tools specific to working within the AppStudio environment. The AppFramework library is unique in that it has features and capabilities that are neither natively provided by the underlying Qt framework nor the ArcGIS Runtime but are necessary and commonly used for developing apps. We are excited to share new features and enhancements added to AppStudio 4.3 release with you in this blog post. New SystemTheme component The SystemTheme component is used to contain the visual theme being used for the device so that it can be used within the app, e.g. light and dark mode. A SystemTheme object contains the information on the operating system theme, which is then used for a number of example controls within the app. You can take a look at the sample code in the API reference and inside the Status Bar sample. We have also implemented this in AppStudio Player version 4.3.  New Battery component (BETA) AppFramework now has a new Battery component to monitor battery levels, power modes, and power source. To see this in action, see Screen and System Info sample.  import ArcGIS.AppFramework.Platform 1.0 .. App{ .. Text { text: "Battery Level: %1%".arg(Battery.level) } .. } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ DocumentDialog component enhancements The DocumentDialog component is used to access documents external to your app, we have added few enhancements to this component such as it now uses the native device file pickers on mobile devices and supports selecting folders and multiple files. You can take a look at the new sample, Working with Files, to see how it is being used to browse and select files.  New VersionNumber component The VersionNumber component provides an interface to check the app's current version, as well as to edit if necessary. Version numbers are separated into three separate numbers, separated by decimal points. The first is the macro number, followed by the minor, and then the micro. This code sample demonstrates a potential usage of VersionNumber, by comparing the version number of the current AppStudio version with one provided in a text field. App{ .. Button { text: "Compare" onClicked: { var ver1 = AppFramework.versionNumber(AppFramework.version); var ver2 = AppFramework.versionNumber("1.2.3"); var result = ver1.compare(ver2); if (result < 0 ) logTextArea.text = "Result: " + result + ". AppFramework Version is less than version 1.2.3"; else if (result === 0 ) logTextArea.text = "Result: " + result + ". AppFramework Version is equal to version 1.2.3"; else logTextArea.text = "Result: " + result + ". AppFramework Version is greater than version 1.2.3"; } } .. }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ CameraDialog component enhancements The CameraDialog component provides access to the system's camera to take photos and movies, using the best resolution supported by the system. For iOS and Android, it will open the device's native camera app. For other platforms (macOS, Windows, and Linux) this component will instead open a custom camera app. In this release, we added few new properties, captureToLocation property which allows saving images or video to a specific location, and captureFlags property to save images and videos to the camera roll. We also just released a new Camera Dialog sample.    New error handling pattern DocumentDialog uses a new error handling pattern, please take a look at the DocumentDialogError component. And EmailComposer has been enhanced with a new error handling pattern, please take a look at the EmailComposerError component. Note: if your app uses the onComposeError signal handler, it needs to be changed to use the new onErrorChanged signal. Please refer to the example below.  EmailComposer { id: emailComposer to: "[email protected]" cc: ["[email protected]", "[email protected]"] bcc: "[email protected]" subject: "Feedback for " + app.info.title onErrorChanged: { var reason = error.errorCode console.log(reason) } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ File Handling updates with Content URIs We introduced the ability to open files in other apps using the AppFramework.openUrlExtenally() method. We enhanced Clipboard share and improved app sharing options with content URIs. We improved File and FileInfo access with content URIs. We added support in EmailComposer for attaching files on Android using content URIs. We enhanced ExifInfo to support Android content URIs. Other changes and new features include the following: We introduced the ability to check the availability of the app using the AppFramework.isAppInstalled() method. We introduced support for removable storage in StorageInfo with the storageType property. We improved the performance of BarcodeReader and added support for barcodes with white lines on black background. We added timeout property in NetworkRequest and Networking. We improved ciphers for encryption on Android in SecureStorage.
