Most of the cameras on the phone have an LED flash that can be used as a flashlight. This tool will allow you to turn on the flashlight on a variety of android versions. To do this, the code uses different approaches depending on the API level of the phone.

📌 The flashlight is switched on and off in one line of code.

📌 If you want to use this tool together with the Vuforia Engine, then the asset contains instructions with a couple of simple steps on how to do it.

📌 Permission to use the camera to operate the flashlight is granted directly from the application, if necessary.

The flashlight has been tested on these Android versions:

• 4.4.2 (ZTE Blade L370);
• 9 (HUAWEI P smart);
• 11 (Galaxy A52, HUAWEI nova 9, Xiaomi POCO M3);
• 12 (POCO X3 Pro).

The demo scene uses a toggle switch that is pleasant to use, as well as a button that allows you to change the flicker frequency.

Below you can find a link to the apk file to make sure the asset is working properly for you.
