[DUG] XE5 Android questions

[Jolyon Smith]

All the information I've been able to find relating to LED control has been very involved, Android SDK level info. 

e.g. http://stackoverflow.com/questions/5503480/use-camera-flashlight-in-android

Flashlight control is tied to the camera and (as I am finding out myself) interacting with the camera is a minefield of different device behaviors and idiosyncrasies, not just permissions.

If there is some wrinkle with your device that FireMonkey does not take into account you may have to wait for Embarcadero to identify and fix it, or roll up your sleeves and try to get to grips with the JNI "bridge" to try to apply the techniques suggested by Android developers.


I'm surprised though.  I thought if the app worked on iOS you could just recompile it for Android ?  ;)
