Rio 10.3.3 Update

-
RAD Studio 10.3.3 update is live.

Just like previous 10.3.2 update got big feature in macOS 64bit platform, 10.3.3 brings long awaited Android 64bit platform support.



Adding 64bit Android platform is pretty straightforward.

You need to add 64bit SDK - make sure it uses the same base paths as 32bit SDK, open your project and 64bit Android will be automatically added to the platform list.

You need to make sure that all deployed resources for 32bit platform are also included for 64bit platform and you are ready to go.

If you want to test application on the device, you have to make sure that your device actually has 64bit Android OS. Even some newer low end devices still use 32bit OS despite the fact they do have 64bit CPUs. If you are about to purchase new device, double check OS bitness.

If your device does not have 64bit OS and you run 64bit Delphi application on it, it will show message "64-bit OS device required".

Unfortunately, 64bit Android debugger has some issues with particular devices and it refuses to run. If you are owner of such device, you can still debug in 32bit mode. Not ideal, but in most cases it will not matter much for the Android side. Most likely debugger fixes will be issued as hot fix rather than update and hopefully before next 10.4 release.

You can build 32bit and 64bit Android APKs separately, and for Google Play Store deployment using App Bundle is the best option. Android App Bundle is similar to iOS universal binary. It packs both 32bit and 64bit variants and Play Store will repack and deliver only one of those variants for every particular device depending on whether it runs 32bit or 64bit Android OS.

In this release, all mobile platforms still run under ARC compiler. This will ease migration to 64bit Android since basically all you need to do is recompile your application.

Unifying memory management and removing mobile ARC compilers is still scheduled for next major release 10.4.

Delphi 12.1 & New Quality Portal Released

-
Image
The Delphi 12.1 update has been released. Besides a number of bug fixes, this release also has a few new features. The most notable ones are the new Split Editor, which allows having multiple files opened side by side; and support for Android API 34. You can find more information about what is new in this update at https://docwiki.embarcadero.com/RADStudio/Athens/en/12_Athens_-_Release_1 However, the greatest change for all Delphi developers is a new bug tracking portal that replaces the old one, still available in read-only mode at https://quality.embarcadero.com/ . The new portal is hosted in Atlassian Cloud https://embt.atlassian.net/servicedesk/customer/portals  or through a redirect https://qp.embarcadero.com and is based on Jira Service Management (JSM), while the internal bug tracking system, which was also migrated to the cloud, was not changed and is running on Jira. This move to the cloud was inevitable, because Atlassian retired their Server line of products. JSM i...

Coming in Delphi 12: Disabled Floating-Point Exceptions

-
Delphi 12 is in the works. One of its small features that will have a huge impact is a change in the default handling of floating-point exceptions, which will now be masked on all platforms. Previously, floating-point exception handling was different across platforms, and most notably on the Windows platform: In VCL and console applications, floating-point exceptions were not masked and would raise an exception. On the other hand, FireMonkey applications had all floating-exceptions masked by default, regardless of which platform they were running on. Basically if you haven't explicitly changed the exception mask in your code to some value other than the default, and you had code that attempted to divide some number with zero, you would get an EZeroDivide exception in previous Delphi versions on the Windows VCL application. In Delphi 12, there is no exception, and the result of such a division will be +INF . So the following code will no longer raise an exception. If you were r...

Assigning result to a function from asynchronous code

-
One of the more common problems that comes up in multi-threading, especially when refactoring existing code, is assigning a result obtained from asynchronous code. In other words, how do you write a function that will return some value, and calculate that value in a background thread? Basically, converting the following code: function GetData(...): string; var Data: string; begin Data := LongTask(...); // assign result of a long-running task to a function Result := Data; end; To this one: function GetData(...): string; var Data: string; begin TThread.CreateAnonymousThread( procedure begin Data := LongTask(...); end).Start; // assign result of a long-running task to a function Result := Data; end; Now, the above code will compile, but it will not achieve the desired functionality. Even if we ignore its thread safety issues (the background thread writes to the Data variable and that can interfere with assigning it to the function result), the funct...
