In my application i have a service created in a different thread than the main one (UI).
Then, in the service, i created 3 others threads that execute in background indefinitely.
But as soon as the phone goes in standby mode, these threads suspend their execution!

If i connect the phone to the pc via usb cable, instead, i see that the threads work properly, without suspending themeselves even when in standby mode.

But how to do not let threads have this behaviour in normal execution?

tnx

SOLVED:

I managed to get this simply by using the PowerManager object, which acquire a PARTIAL_WAKE_LOCK that leave the cpu active from the acquire() to the release().

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
 PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag");
 wl.acquire();
   ..CPU will stay on during this section..
 wl.release();

    I managed to get this simply by using the PowerManager object, which acquire a PARTIAL_WAKE_LOCK that leave the cpu active from the acquire() invocation till the release() invocation.

    In this way even if phone goes in stanbdy mode, thread is sure to be running.

    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
 PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag");
 wl.acquire();
   ..CPU will stay on during this section..
 wl.release();
