Signal handlers are not supposed to contain “business logic” or make library calls such as printf. See C11 ยง7.1.4/4 and its footnote: Thus, a signal handler cannot, in general, call standard library functions. All the signal handler should do is set a flag to be acted upon by non-interrupt code, and unblock a waiting system … Read more
When canceling the AlarmManager do not use a PendingIntent with a flag of FLAG_CANCEL_CURRENT. Instead, cancel the PendingIntent explicitly after canceling the alarm: am = (AlarmManager) getSystemService(getApplicationContext().ALARM_SERVICE); Intent i = new Intent(getApplicationContext(),AlarmReceiver.class); PendingIntent p = PendingIntent.getBroadcast(getApplicationContext(), 0, i, 0); am.cancel(p); p.cancel();
The most robust solution is to use a subprocess, then kill that subprocess. Python2.6 adds .kill() to subprocess.Popen(). I don’t think your threading approach works as you expect. Deleting your reference to the Thread object won’t kill the thread. Instead, you’d need to set an attribute that the thread checks once it wakes up.
First set the Alarm Manager as below Calendar calendar = Calendar.getInstance(); calendar.set(Calendar.HOUR_OF_DAY, 18); calendar.set(Calendar.MINUTE, 30); calendar.set(Calendar.SECOND, 0); Intent intent1 = new Intent(MainActivity.this, AlarmReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE); am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent); Create an Broadcast Receiver Class “AlarmReceiver” in this raise the notifications when onReceive public class AlarmReceiver extends … Read more

You can do it with AlarmManager, heres a short example. First you need to set the alarm: AlarmManager am = (AlarmManager) con.getSystemService(Context.ALARM_SERVICE); Date futureDate = new Date(new Date().getTime() + 86400000); futureDate.setHours(8); futureDate.setMinutes(0); futureDate.setSeconds(0); Intent intent = new Intent(con, MyAppReciever.class); PendingIntent sender = PendingIntent.getBroadcast(con, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); am.set(AlarmManager.RTC_WAKEUP, futureDate.getTimeInMillis(), sender); Next, You need to create a … Read more
First of all, it is really very bad pattern to run service forcefully against the user’s willingness. Anyways, you can restart it by using a BroadcastReceiver which handles the broadcast sent from onDestroy() of your service. StickyService.java public class StickyService extends Service { private static final String TAG = “StickyService”; @Override public IBinder onBind(Intent arg0) … Read more
It’s not very pretty, but I had to do something similar in a cross-platform way, and I came up with using a separate thread. Signal based systems did not work on all platforms reliably. Use of this class could be wrapped up in a decorator, or made into a with context handler. YMMV. #!/usr/bin/env python2.7 … Read more
The stock alarm clock app is open source, so check it out by yourself. Preference Layout see here: <?xml version=”1.0″ encoding=”utf-8″?> <PreferenceScreen xmlns:android=”http://schemas.android.com/apk/res/android” android:title=”@string/set_alarm”> <CheckBoxPreference android:key=”on” android:title=”@string/enable”/> <Preference android:key=”time” android:title=”@string/time”/> <com.android.alarmclock.AlarmPreference android:key=”alarm” android:title=”@string/alert” android:ringtoneType=”alarm” android:showDefault=”false” android:showSilent=”false” /> <CheckBoxPreference android:key=”vibrate” android:title=”@string/alarm_vibrate”/> <com.android.alarmclock.RepeatPreference android:key=”setRepeat” android:title=”@string/alarm_repeat” /> <EditTextPreference android:key=”label” android:title=”@string/label” android:dialogTitle=”@string/label” /> </PreferenceScreen> Preference activity see here, note … Read more
Try this flag: PendingIntent.FLAG_UPDATE_CURRENT Instead of: PendingIntent.FLAG_CANCEL_CURRENT So the PendingIntent will look like this: PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, alert.idAlert, intent, PendingIntent.FLAG_UPDATE_CURRENT) (Make sure that you use same alert object and mContext!) A side note: If you want one global AlarmManager, put the AlarmManager in a static variable (and initialize it only if it’s null).
