I think I worked it out. time() carries on incrementing while the device is asleep, but of course can be manipulated by the operating system or user. However, the Kernel boottime (a timestamp of when the system last booted) also changes when the system clock is changed, therefore even though both these values are not … Read more
Add following code in your onCreate() method: Thread thread = new Thread() { @Override public void run() { try { while (!thread.isInterrupted()) { Thread.sleep(1000); runOnUiThread(new Runnable() { @Override public void run() { // update TextView here! } }); } } catch (InterruptedException e) { } } }; thread.start(); This code starts an thread which sleeps … Read more
The speed of a computer processor, or CPU, is determined by the Clock Cycle, which is the amount of time between two pulses of an oscillator. Generally speaking, the higher number of pulses per second, the faster the computer processor will be able to process information. The clock speed is measured in Hz, typically either … Read more
The documentation lacks some details here. What VirtualBox does every 10 seconds is just slight adjustement (something like 0.005 seconds). Only when the time difference reaches a threshold (20 minutes by default) a “real” resync is done. You can reduce the thresold (i.e. to 10 seconds) with the following command: VBoxManage guestproperty set <vm-name> “/VirtualBox/GuestAdd/VBoxService/–timesync-set-threshold” … Read more
I would avoid using System.currentTimeMillis() for measuring elapsed time. currentTimeMillis() returns the ‘wall-clock’ time, which may change (eg: daylight savings, admin user changing the clock) and skew your interval measurements. System.nanoTime(), on the other hand, returns the number of nanoseconds since ‘some reference point’ (eg, JVM start up), and would therefore not be susceptible to … Read more
That function is simple enough that you can use ctypes to access it: #!/usr/bin/env python __all__ = [“monotonic_time”] import ctypes, os CLOCK_MONOTONIC_RAW = 4 # see <linux/time.h> class timespec(ctypes.Structure): _fields_ = [ (‘tv_sec’, ctypes.c_long), (‘tv_nsec’, ctypes.c_long) ] librt = ctypes.CDLL(‘librt.so.1’, use_errno=True) clock_gettime = librt.clock_gettime clock_gettime.argtypes = [ctypes.c_int, ctypes.POINTER(timespec)] def monotonic_time(): t = timespec() if clock_gettime(CLOCK_MONOTONIC_RAW … Read more
I had the same problem and got it resolved by just restarting the emulator using emulator power button.
