I want to download the Android Studio and Android SDK for crating the Android apps but the problem is I can't download them. When I try to download the Android Studio, the download fails after some time and I have tried three different PCs but the same problem in all of them. When installing Android SDK, it says no JDK found and now I don't know how can I make the software to work. I tried with both Windows 7 and Windows 10 operating systems, nothing works.
