I'm creating this incredibly simple app, since I'm just starting with Android and I have no experience with Java what so ever. Anyhow, all I have is a timer and a button. Obviously the button starts the timer which counts down from 60 ( 1 minute ) and then vibrates when it's done. All worked fine up until the point I decided to press the lock screen button to put the phone to sleep. I found out that the timer in my app stops going until I unlock the phone. This also happens if I set the auto sleep time to less than 60 seconds and the phone falls asleep on it's own. My question is - how can I have that chronometer running even when the screen is not active?

You need to make this using BroadCastRecievers
for system-calls. (Related Helpful question)
You can also play off the life-cyles of the Activity
using the PowerManager
.
Example using PowerManager
:
@Override
protected void onPause()
{
super.onPause();
// If the screen is off then the device has been locked
PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
boolean isScreenOn = powerManager.isScreenOn();
if (!isScreenOn) {
// The screen has been locked
// Continue your timer
}
}
