Running camera as background service in Android9, IMX8qxp

[wasim_nazir]

Hi Guys,

I need to run camera app as background java service in Android9, IMX8qxp. For which I use built-in camera app as background service and trying to run in background at BOOT_COMPLETE.

I am facing this crash, few times on reboot

============================================================================

What can be the issue for the crash. Is it because the camera/media native services are not ready at BOOT_COMPLETE. Full log is attached below.

Any suggestions will be helpful.

Thanks in Advance,

Hello wasim,

This is not supported by android BSP, however We have observed similar issue when camera was connected to the board while kernel was booting. Please try connecting USB camera after Android has booted successfully. for the backround for the apps
