android 4.4, service 'SurfaceFlinger' died


I am running a native process that is capturing the screen in a loop using ScreenshotClient. randomly after several runs when I close the process I get "service 'SurfaceFlinger' died" and the screen restarts. This does not happen in android 4.2.

this is the backtrace:

I/DEBUG   (  111): backtrace:

Solution

  • when I cleanly close the process instead of killing it, SurfaceFlinger doesn't die anymore.
