I am adding additional battery properties that require a shutdown under
certain conditions. I have a requirement that the user be notified of the
shutdown reason
Basically I am adding additional checks like shutdownIfOverTemp() in
BatteryService, so I can use that function as an example of where I would
like to add a reason notification to the end user.
The standard behavior simply shuts down the phone (at least in 4.1.2 that I
am based on):
private final void shutdownIfOverTemp() {
// shut down gracefully if temperature is too high (> 68.0C)
// wait until the system has booted before attempting to display
the shutdown dialog.
if (mBatteryTemperature > 680 &&
ActivityManagerNative.isSystemReady()) {
Intent intent = new Intent(Intent.ACTION_REQUEST_SHUTDOWN);
intent.putExtra(Intent.EXTRA_KEY_CONFIRM, false);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(intent);
}
}
I'm not sure what my options are to notify the user.
I can't display a toast from the service right?
It might be OK to set EXTRA_KEY_CONFIRM to true (iffy in the case of being
over temp), but I don't think this provides me a way to show a message
anyway (I'll try it next)
The only way I can think of is to send a new intent
SHUTDOWN_REQUEST_BATTERY_OVERTEMP then define an activity that would catch
it, display something ("system shutting down due to battery temperature")
and that activity would then send ACTION_REQUEST_SHUTDOWN? and I would have
to do this for every separate shutdown reason or can I add an additional
extra to ACTION_REQUEST_SHUTDOWN that would indicate the shutdown reason?
