alarmmanager

问题 I have a minor problem in one of my apps. It uses a BroadCastReceiver to detect when a call finishes and then performs some minor housekeeping tasks. These have to be delayed for a few seconds, to allow the user to see some data and to ensure that the call log has been updated. I'm currently using handler.postDelayed() for this purpose: public class CallEndReceiver extends BroadcastReceiver { @Override public void onReceive(final Context context, final Intent intent) { if (DebugFlags.LOG

问题 Could someone explain me different situations to use AlarmManager vs Handler with examples please. Any disadvantages of using these two as alternate to each other? Thanks. 回答1: They have little to do with one another. I am assuming you are referring to using something like postDelayed() on Handler for polling, which is but one small feature of Handler . You would use postDelayed() (also available on any widget or other subclass of View ) in an activity for simple timing events that are within

问题 I have created an On Boot Receiver to repeatedly call a wakeful intent service every 5 minutes but cannot figure out how to start the service immediately when the app is installed..? I do not want to rely on the user rebooting their device before it starts to run! Here is my code so far : public class OnBootReceiver extends BroadcastReceiver { private static final int PERIOD = 300000; // check every 5 minutes @Override public void onReceive(Context context, Intent intent) { AlarmManager mgr =

问题 I have been stuck on it for days. I need to execute a function every minute. This function is making a POST call from the App to the Server and is transferring the location of the user per minute. The location coordinates are transferred for few hours, however, after few hours the transfer of location coordinates to the Server stops on its own.
