ART is still experimental. It's not ready for end-users yet: it's only included at all so developers can find problems with their own apps. It doesn't surprise me at all that games that make heavy use of native code don't work with ART. You should ignore anything people say about the performance characteristics of ART, for the same reason. It could get ...

This is a crash and restart of the android runtime, without a crash and reboot of the underlying linux operating system kernel. The uptime refers to the underlying linux, so it is maintained across the framework restart. The difference between a framework crash and restart vs. a kernel crash and reboot is not very apparent to the end user, since there's ...

When the app is closed and reopened the process has to be redone. This method is called JIT (Just In Time) In ART unlike compiling every time, when the ...

This issue gets pretty clear by the second screenshot, which I will repeat here: Battery usage (click image for larger variant) Please pay attention to its lower half, just below the graph, and let me point out some details: Mobile network signal: This bar has no black, which means the radio was on all the time. Further, the colors indicate a relatively ...

This may not be exactly what you are seeing, but I have seen situations where the "home"/launcher app will be garbage collected. The next time the phone returns to the home screen, it shows a loading screen as it restarts the launcher app. Depending on the model of phone, ROM, and launcher you use, this initialization screen may be different, and it may ...
