alarm

问题 I am writing an android application to simply play an alarm no mater what mode the phone even if it is in silent mode. I found this question and used the code from the answer to override the current volume state. My code looks like this: Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); if (alert == null){ // alert is null, using backup alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); if (alert == null){ // alert backup is null, using 2nd backup

问题 My app has an alarm function using UILocalNotification, and it works great. However, if the user uninstalls the app, then later REINSTALLS it, he would receive all the "in between" notifications at once. I have tried to call: [[UIApplication sharedApplication] cancelAllLocalNotifications]; if it's the first time the app is launched, but it doesn't help, because the notification is received even before application:didFinishLaunchingWithOptions: is called. This was worse in 4.0 when the alarm

问题 I have a problem. I am trying to make a broadcast receiver acquire a wake lock so my alarm will wake the phone from sleep mode. In the broadcast receiver below, the program crashes with "source not found" on line "sCpuWakeLock.acquire(); when the class "AlarmAlertWakeLock" is called by AlarmReceiver. Any idea what's going on? Is there a better way to do what I'm trying to do? In one file: import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent;

问题 Is it possible to access information like the alarm clock time and change it from a different application on the iPhone. And if its possible to do it, can it be approved by the app store to sell it? 回答1: You can certainly do it—the CFPreferences API would probably be the right approach—but you definitely wouldn't get allowed into the App Store. If you're looking to make an alarm-clock application, check out the Scheduling Local Notifications docs. 来源： https://stackoverflow.com/questions

问题 I have to crate a sample app in which when I clicked a button that should open the native alarm clock so that user can use it for setting alarm? 回答1: If the Clock app supported a URL scheme, like the Phone app’s tel:// or the Mail app’s mail:// , you could open it with the standard [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"..."]] approach. Unfortunately, to my knowledge, it doesn’t, so all you can really do is prompt the user to open that app themselves to set up the

问题 I have an app running on Android that creates an alarm that is fired every 24 hours. This alarm is working as expected. However, when I update my app through Google Play this alarm is lost because the end user does not open the app right after the app was updated. My opinion is that Android is deleting the alarms my app created when the app was updated. Does anyone already got this situation? Is there any way to persist the alarms when the app is updated? 回答1: Your solution is as simple as
