How to turn on front flash light programmatically in Android

Question

I want to programmatically trigger the front flash on Android (not with the camera preview). I looked it up on Google, but the advice I received directed me to this page.

Does anyone have links or an example of the code?

Answer 1

For this problem you should:

1. Check whether the flashlight is available or not.

2. If so then Turn Off/On

3. If not then you can do whatever, according to your app needs.

To determine whether the device has flash:

You can use the following:

 context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH);

This will return true in the presence of a flash and false otherwise.
