Prevent device going to sleep about tower HOT 8 CLOSED

The wake-lock should only be enabled when receiving heartbeats from the drone. IF not there could be problem for the user where he forgets the app open without a drone connected.

@JaredReabow: the display dims which in daylight can be a big issue

from tower.

Stumbled about the same issue. While being outside in daylight the display dims and became almost impossible to see.

I think the reason for this behavior is that the wake lock is aquired with the parameter "SCREEN_DIM_WAKE_LOCK".

To keep the screen fully bright "SCREEN_BRIGHT_WAKE_LOCK" should be used. Best would be to set it together with "ON_AFTER_RELEASE".
Could look like this "pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK|PowerManager.ON_AFTER_RELEASE, "CPU");"

just now I read on http://developer.android.com/reference/android/os/PowerManager.html that "SCREEN_BRIGHT_WAKE_LOCK" is deprecated in API level 13 :(
Will it still work or is there an workaround?

Maybe with this: http://developer.android.com/reference/android/view/View.html#setKeepScreenOn(boolean)

But there should be a preference to keep enable this. On thing I notice when I'm flying is that the thing I mostly use is the voice notifications, so keeping the screen dim helps to save the battery.

I could not find a way to avoid the screen goes off after some time without touch at the screen.

I tried SCREEN_BRIGHT_WAKE_LOCK on my Nexus7 with android 4.2.2 and it still works.
As long as it works it's easier to implement it this way :)
To use a preference is a god idea.
Just launched a pull request (#135) with my suggestion for this topic.

The code from @realbuxtehuder at pull #135 fixed this issue.
