Public methods

batchPrefetchStartupBuildProps

public void batchPrefetchStartupBuildProps ()

Micro optimization (about 400 millis) by prefetching all props we need rather than call 'adb getprop' for each one. i.e. It is just as fast to fetch all properties as it is to fetch one. Things like device.getApiLevel(), checkApiLevelAgainstNextRelease and getBuildAlias all call `adb getprop` under the hood. We fetch them in one call and call NativeDevice.setProperty. Even if we don't do this, NativeDevice will itself call setProperty and cache the result for future calls. We are just doing it slightly earlier. If the device is in recovery or there are other errors fetching the props, we just ignore them.
