Check if the screen is unlocked android service

Question

I’m developing an app that has a service of AlarmManager who subsequently calls a Service. It turns out that when you start the Service I want to check if the phone is in use, IE, with the screen access and unlocked, because if it displays a notification, otherwise starts a Activity. Is there any method or class to check this and give me a feedback?

Try the Keyguardmanager:

KeyguardManager myKM = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
if( myKM.inKeyguardRestrictedInputMode()) {
 //it is locked
} else {
 //it is not locked
}
