Android Question ACL flashlight problem

[RichyK68]

Hi,
I've had to get a new phone because, apparently, Samsung Galaxy S4's don't take too kindly to being dropped a couple of feet onto concrete when wrapped in a huge shock-proof case. I've now got an excellent LG G2, but I've noticed that the app I'm developing which makes use of the ACL library to turn the flashlight on and off (like a torch) doesn't work on the G2. It doesn't error, it just doesn't turn the light on. Other torch apps on my phone work fine.

How else can I turn the light on? And is there a consistent way across Android to do this?

Thanks,

Richard

I recommend you to use CameraEx class. You should check whether the list returned from GetSupportedFlashMode includes the value "torch".

Thanks. I've moved my code over from ACL to use CameraEx. I check for the "torch" mode to see if it's supported in the camera Ready event, and it is, so I enable the torch button. When I press it, it does this:

MyCameraEx.SetFlashMode("torch")

and if I check MyCameraEx.GetFlashMode straight after I get "torch" but the torch still doesn't come on. No error either. Other torch apps work though.

In my _Resume event I initialize it like this:

MyCameraEx.Initialize(Panel1, False, Me, "MyCamera")

Anything else I should check? Thanks

Have you called CamEx.CommitParameters?

Right after MyCameraEx.SetFlashMode("torch")? Just tried that, still refuses to turn the light on

Got it! I have to then follow it with MyCameraex.StartPreview.

Thanks for your help
