We are excited to announce the release of AppStudio for ArcGIS 3.1 Beta.  Downloads are available through the Early Adopter Community and we encourage you to participate in the beta program to try out new features and enhancements, and report bugs.  Your feedback will greatly help us improve AppStudio and deliver a stable and high-performance product for everyone.  
Disclaimer: Do not build apps to be used in production or submit to app stores using the Beta software.

 A few of the highlights include: 

Desktop UI enhancements 
We have UI updates to AppStudio Desktop based on Esri’s Calcite style standard to keep visual consistency across Esri’s products.  For example, the New App button was moved down to the main gallery area, and the header and side panel border width was increased.   AppStudio Desktop’s Settings tool has also received a UI/UX revamp.  It's easier than ever to use the Settings tool to navigate and find all the options and settings organized into sections.  Also as part of redesign, the contents of Advanced Settings dialog is now available and integrated into the Licensing, Platforms & Advanced sections.
Upgrade ArcGIS Runtime to 100.3 
The ArcGIS Runtime version has been upgraded from 100.2.1 to 100.3, which enables you to take advantage of new functionalities, enhancements and bug fixes received in ArcGIS Runtime 100.3. 
Upgrade Android API level to 26
With AppStudio 3.1 beta, Android build tools have been upgraded from API level 23 to 26.
Enhancements for Background Location (Android)
Android 8.0 puts a restriction around background processes that it can run for at most 15 minutes since the app goes to background. We have made significant tweaks to overcome these operating system level constraints and we are excited to announce that Background Location on Android is now supported using Foreground Services. A Notification is displayed when the app enters background state and stays visible until you close the task. However, note that the OS may still decide to terminate this task if the device is under tremendous memory crunch from other apps on the device. 
Enhancements for Local Notification
Local Notification on Android 8.0+ now supports Notification Channels. Few optimizations went into the underlying iOS stack as well.
Support for Bluetooth Low Energy (BLE) devices 
We have added the following NEW components into AppFramework Devices plugin to support communication with Bluetooth LE devices. 
  • BluetoothLEDevice
  • BluetoothLEService
  • BluetoothLECharacteristic
  • BluetoothLEDescriptor
  • ServiceListModel
  • CharacteristicListModel
  • DescriptorListModel
You can now create AppStudio apps that have the ability to discover and connect to Bluetooth LE devices, discover services, and read or write characteristics for devices that support it. 
Note: If you use these in your app, you will be able to see it on your device using the new Player available via beta testing or if you build the app using cloud make of the AppStudio Desktop beta.
Support for cryptographic hashes
CryptographicHash and MessageAuthenticationCode components have been added to the AppStudio AppFramwork to provide a way to generate cryptographic hashes or hash-based message authentication codes, which can be used to verify the integrity of networking requests and responses. 
Enhancements for Position and Devices plugins
AppStudio’s 3.0 release introduced two new plug-ins, Positioning and Devices, allowing you to create an app that interacts with high - accuracy GPS receivers.  Work has continued to improve these two plugins with many performance and stability related bug fixes and enhancements, such as DeviceDiscoveryAgent crashes issue on iOS.  A new property, pairingStatus was also introduced to the SerialBluetoothDevice component, which returns the pairing status of a Bluetooth device. Notice that the GNSS Info sample app include supporting for high-accuracy GPS receivers.  You can download and check the source code through AppStudio Desktop 3.1 (Beta).   
Email Composer 
A new Inter-App Communication plugin has been added to AppFramework. This plugin includes the EmailComposer component, allowing you to launch an email client with a pre-filled draft email.  You can modify, delete, save, or send this draft email.  
Check Capability 
We have added a new checkCapability method into the AppFramework to check if your device has granted critical permissions such as Location, Storage, Camera, and Microphone. 
Secure Storage Enhancements
Secure Storage has introduced two new properties - maximumValueLength and maximumKeyLength, allowing you to determine the limit on the length of the key and value, with these property, your apps can now take full advantage of device limit.  Note that previously the maximum value and key size was 214 characters by default.  
API references of Bluetooth LE related components, CryptographicHash, MessageAuthenticationCode, Email Composer, and Check Capability are available at Qt Creator Help documentation included with the AppStudio Desktop 3.1 (Beta) install.       
A more comprehensive list of new features and enhancements can be found in the Early Adopter community website.
