1. Let your kernel module send an UEvent, whenever the alert raises.
This can be done by KOBJ_UEVENT(,,.,,)
2. Create a Simp
as said below create a sysfs entries for the aleart.
1. for checking for the alert (it could be something like toggling the
switch- saying true or 1 when you have a message and false or 0 when no
message).
2. for message
create a handler in the android stack to watch 1st sysfs entry to check for
you can create a file [1] as a sysfs entry on your system, create a
android service pooling that information and display to user.
[1] example: you can create a "notifications" file and put printk content.
$ cat /sys/kernel/notifications
YOUR MESSAGE
