Resumable subs in debug mode are optimized in the same way other subs are optimized. You can see the difference in this video: Starter service is never destroyed until the process is killed – if you carefully read the automatic foreground notifications tutorial then you should be aware to a significant behavioral change in Android 8+. The OS kills services while the app is in the background. In previous versions the OS never killed specific services (only the complete process). This change made it much more difficult to work with the starter service as you could no longer assume that the starter service is running. Starting from B4A v8.3 the starter service will never be paused until the process is killed. Internally it switches from the service context to the application context. Several other important debugger optimizations. Bit.ArrayCopy method. Same as ByteConverter.ArrayCopy. New File methods: CopyAsync, Copy2Async, ReadBytes, WriteBytes and ListFilesAsync. Support for Java 8 jars and AARs. Ctrl + Click on class types and custom types. Autocomplete improvements. Autocomplete in CallSub methods B4A Sdk Manager v3.27 – Supports Java 10. Files can be added to groups directly. For loops optimization (in release mode). BitmapCreator v3.60 is included as an internal library. xCustomListView v1.63 is included as an internal library. XUI v1.70 is included as an internal library. This is a large update to XUI library with support for text measurements and other features. Phone.ShellAsync – Asynchronous version of Phone.Shell. Bug fixes and other minor improvements.
