阅读更多关于 Compatible version of Android JobScheduler - alternative [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago .

阅读更多关于 Support vs “real” libraries and “classes could not be found”

问题 When I try to use the RecyclerView in a test project when Im about to try out Android 5.0 Lollipop, I see the following on Googles site: 1) What puzzles me is that they use the support thing instead of the "real" thing as provided in API 21. I was expecting to not use the support-package as I am running 5.0 on the device, have SDK 21 downloaded and installed.

阅读更多关于 Properly route non internet Wifi sockets & Cellular Internet request (Android L & M)

问题 Is it possible to dedicate a WiFi network (to a device with no internet access) to a socket in an app and keep Cellular network as the default internet connection for the Android device (and other network requests from the app)?
