What is the function of Phone.PartialLock?

I have no effects on my phone.

Dim phone As PhoneWakeState

Phone.PartialLock '???
'Phone.ReleasePartialLock ' = end of .PartialLock

Many Thanks.

More detail Here.

KeepAlive causes either a SCREEN_DIM_WAKE_LOCK or a SCREEN_BRIGHT_WAKE_LOCK depending upon the BrightScreen parameter and both have the ACQUIRE_CAUSES_WAKEUP flag set.

PartialLock causes a PARTIAL_WAKE_LOCK.

Is it normal behaviour that when using a PartialLock that the current activity is paused?
If so, what is the purpose of this lock? I can't find any symptoms of its behaviour.

The reason I'm looking at locks, is that I have an application which runs an SQL query from a service at an interval. This uses the httputils module and service. The call back from this requires an Activity module, and this all works fine when the device is running.
However I'd like the SQL query to still pull back the data and analyse even when the screen turns off or power button pressed.
Is this even possible?

No.

The lock is to avoid that the device goes to sleeping mode.
Or that the brightness changes.
For details see the documentation links given above.

So you don't want to lock anything, do you?

I don't mind the screen turning off, but I need the Activity to still run.

For some reason the partial locking seems to do nothing on my device - Galaxy Nexus.
According to the log, the activity is paused each time the device turns off itself after inactivity.

The activity will pause when the screen turns off. You should use a service instead.

Is there anyway a service can be used as a callback for HttpUtils?
Or will I have to use HttpClient directly in the service and not use Httputils and HttpUtilsService?

Yes. Just set the service name in the CallbackActivity property.

Many thanks Erel.
I will try that, I didn't realise it was possible.
