flashlight in a service

[salmander]

Hello All,

I am trying to use flashlight in a service. I was searching b4a forum and the only library I found to use the Flashlight is the Advanced Camera Library (ACL). But, ACL is an activity object and can't be declared in a service. What shall I do?

I know services can use flashlight, as there are apps which uses flashlight as notifications e.g: on incoming sms etc.

Please help.

You can also use CameraEx class to set the flash to torch mode. Though it is also an activity object.

A possible solution is to start an invisible activity.

Thanks Erel.
What I am trying to achieve is when an intent of incoming call is received, the flashlight will start blinking, thus, using flashlight as a notification light. So if I use an activity for the flash in torch mode, wouldn't the activity be in onPause state when the phone is ringing?

It will be problematic. You can call StartActivity and bring your activity to the front. However it will then interfere with the telephone activity.
