<!-- Whether to send a user activity event to PowerManager when a dream quits unexpectedly so
that the screen won't immediately shut off.
When a dream stops unexpectedly, such as due to an app update, if the device has been
inactive less than the user's screen timeout, the device goes to keyguard and times out
back to dreaming after a few seconds. If the device has been inactive longer, the screen
will immediately turn off. With this flag on, the device will go back to keyguard in all
scenarios rather than turning off, which gives the device a chance to start dreaming
again. -->
<bool name="config_resetScreenTimeoutOnUnexpectedDreamExit">false</bool>
<!-- The prefixes of dream component names that are loggable.
Matched against ComponentName#flattenToString() for dream components.
If empty, logs "other" for all. -->
