A poorly-designed alarm can cause battery drain and put a significant load on servers. For this reason, on Android 4.4 (API level 19) and higher, all repeating alarms are inexact alarms. A repeating alarm has the following characteristics: An alarm type. For more discussion, see Choose an alarm type. A trigger time. If the trigger time you specify is in the past, the alarm triggers immediately. The alarm's interval. For example, once a day, every hour, or every 5 minutes. A pending intent that fires when the alarm is triggered. When you set a second alarm that uses the same pending intent, it replaces the original alarm." How can I implement the whole thing in B4A with receivers, to start a receiver every day at 10 o clock?
