Developer Lin Shou Shan (superlevin) from Taiwan has a simple demo project on using the Android flashlight feature in Delphi XE5 Firemonkey. The demo is up on Github and is really on a few lines of code. There are a few different ways people have figured out how to turn their phones into a flashlight and this demo makes use of the flash (also known as torch) functionality of the Android device. The TCameraComponent that ships with Delphi XE5 has a property called HasFlash which tells you whether the torch device is available. If it is available you can use code like this to turn on the flash: CameraComponent1.TorchMode := TTorchMode.tmModeOn;. This code should probably also work in Delphi XE6 and AppMethod. I believe you also need to add the Android permission: android.permission.FLASHLIGHT. You can also check out a question and answer pair on StackOverflow to see the actual Java code that does flashlight code.
