Answer by 4carlos for [XA2, 3.3.0.16] Can't open files with any android apps

@Maarten: Some apps have implemented their own "open method". One example is TextMaker (compiled in 2015), part of the SoftMaker Suite. This old suite is not affected, but all "newer" apps like Threema, Conversation, Notepad, PDF Viewer, Filemanager +, Ghost Commander etc. It is simply a bug in Aliendalvik since 3.3.0.xx. This does not occur in SFOS 3.2 and is independent of @coderus ADC.
