阅读更多关于 C: SIGALRM - alarm to display message every second

问题 So I'm trying to call an alarm to display a message "still working.." every second. I included signal.h. Outside of my main I have my function: (I never declare/define s for int s) void display_message(int s); //Function for alarm set up void display_message(int s) { printf("copyit: Still working...\n" ); alarm(1); //for every second signal(SIGALRM, display_message); } Then, in my main while(1) { signal(SIGALRM, display_message); alarm(1); //Alarm signal every second. That's in there as soon

Android pending Intent - Alarm - same code six(6) apps

阅读更多关于 Android pending Intent - Alarm - same code six(6) apps

问题 I found something strange yesterday. While testing app with localization versions(different apps-dif. packages, the same code) I found one interesting bug - the app sets alarm with the AlarmManager and pending Intent - when the broadcast is fired , only one app gets activated and executes the pending intent and all others apps(only different language) are not reacting at all. Is this android bug?? I'm expecting that the set Alarm will trigger every one app that has it's own set Alarm but

问题 I have been researching for any possible way to do an alarm app like the app in AppStore (AlarmMon, Rocket Alarm). Which they can alarm with sound continuously even app is in background. I've tried to turn off their location permission for the case that app using the CLLocationManager to update and extend the backgroundTimeRemaining. When the alarm is playing sound, It doesn't stop even you receive a phone call (You can accept the call, talk to caller and hear their alarm sound simutaneously)

Alarms on the Google Android

阅读更多关于 Alarms on the Google Android

问题 I'm noticing a strange thing with Alarms on Android - they don't always wake up the device at the correct intervals. For example, if I set an alarm to start a service every 5 minutes (using RTC_WAKEUP, or similar), everything works fine until the device goes to sleep - after that, the alarm may not fire for minutes, or close to an hour. It usually does fire eventually - and it always fires if I wake the device by pressing Menu. Using repeating alarms (vs. re-setting them each time) has the
