I had problems installing Android Studio, it crashed every time I added a widget to the layout in the design view. So I downloaded the latest version, which was a preview build. This fixed a failure. However, this was not an installer, but all the files were archived. So I uninstalled my old version of Android Studio and replaced it with this preliminary version.
Now I get this error every time I open AS: AssertionError: build-tools-23.0.0 doesn't match build-tools-23.0.0-preview In addition, AS no longer recognizes my phone when I try to create my own application, so I can not test it. I am not sure if these two problems are related.
