As Sarina already mentioned in the community site, last week Embarcadero released a second patch for Delphi and C++Builder 10.2 Tokyo. The first patch was focused on tool chain issues, while this new one addresses several issues for Android platform support. Namely, some of the fixes relate with the platform changes in editing (causing problems when using the backspace key) while other address regressions (and performance issues) introduced in 10.2 Tokyo and caused by platform changes in threading support.

You can find a list of open Quality Portal issues the patch addresses in the download page at This patch is available also for trial customers.

The matching source code is available only for registered users at Notice that the source code includes changes that affect multiple platforms, but we haven't released the updated DCU files for those other platforms. In other words, PAS and DCU will most likely be out of synch either with or without the source code patch, depending on the target platform, and you should consider enabling this new source code for Android specific projects or using it as reference only.

We know this is no ideal and this patch is intended as a temporary solution, while we complete and test a full update of the product, including all internal fixes and all platforms.
