Project Astoria, the Microsoft intiative which was to bring Androd apps to Windows 10 may have hit some roadblocks. The code which allowed users to sideload Android apps onto handsets running Windows Insider builds has been removed for the latest builds and reports are emerging of technical and political problems for the initiative.
Microsoft made a decision to offer Android emulation in Windows 10, allowing apps to run without needing to be rewritten or recompiled. Upsides and downside abound. Wider app choice for customers, Windows native developers feeling betrayed.
Ultimately it may prove to be the risk of legal action from Google that kills Astoria. Leaving Microsoft to decide whether it wants to go down the route of helping developers to port apps from Android to Windows 10.
