eclipse - Android Widget - Click for action, update under 30 minutes, separate instances -
i've tried create widget that, on click calls routine on configuration activity, on update calls routine on configuration activity, update must under 30 minutes , instance created must work separately (in onupdate , in onclick).
the code below: click doesn't work (can't see toast message , other function) update works fine first instance multiple widget instance works bad: if create 2 instances between 10 seconds (and refresh set 20 seconds) update every 10 seconds.
that's manifest:

for timing under 30 mins , multiple instances i've decided use 1 timer instances.
below code oncreate of configuration class:
private static long millis = 20000; sharedpreferences read = context.getsharedpreferences(prefs_name, 0); string firstinstance = read.getstring("firstinstance", "ko"); if (firstinstance.equals("ko")) { sharedpreferences.editor write = context.getsharedpreferences( prefs_name, 0).edit(); write.putstring("firstinstance", "ok"); write.commit(); intent intent = new intent(controllowidget.my_widget_update); pendingintent pendingintent = pendingintent.getbroadcast( configurazione.this, 0, intent, 0); alarmmanager alarmmanager = (alarmmanager) getsystemservice(alarm_service); calendar calendar = calendar.getinstance(); calendar.settimeinmillis(system.currenttimemillis()); calendar.add(calendar.second, 10); alarmmanager.setrepeating(alarmmanager.rtc_wakeup, calendar.gettimeinmillis(), millis, pendingintent); controllowidget.savealarmmanager(alarmmanager, pendingintent); } revert process ondisabled of widgetclass:
@override public void ondisabled(context context) { // todo auto-generated method stub //super.ondisabled(context); sharedpreferences.editor write = context.getsharedpreferences(prefs_name, 0).edit(); write.putstring("firstinstance", "ko" ); write.commit(); myalarmmanager.cancel(mypendingintent); } static void savealarmmanager(alarmmanager talarmmanager, pendingintent tpendingintent){ myalarmmanager = talarmmanager; mypendingintent = tpendingintent; } now, setting button action , own update: class declaration:
public static string action_widget_clicked = "your.packagename.action_widget_clicked"; public static string my_widget_update = "your.packagename.my_widget_update"; onreceive method:
@override public void onreceive(context context, intent intent) { // todo auto-generated method stub super.onreceive(context, intent); choice = false; // ////toast.maketext(context, intent.getaction(), // ////toast.length_long).show(); // choice=false; bundle extras = intent.getextras(); if (my_widget_update.equals(intent.getaction())) { choice = false; appwidgetmanager appwidgetmanager = appwidgetmanager .getinstance(context); componentname thisappwidget = new componentname( context.getpackagename(), controllowidget.class.getname()); int[] appwidgetids = appwidgetmanager .getappwidgetids(thisappwidget); onupdate(context, appwidgetmanager, appwidgetids); // ////toast.maketext(context, "autoupdate", // ////toast.length_long).show(); } else if (action_widget_clicked.equals(intent.getaction())) { // choice =true; appwidgetmanager appwidgetmanager = appwidgetmanager .getinstance(context); componentname thisappwidget = new componentname( context.getpackagename(), controllowidget.class.getname()); int[] appwidgetids = appwidgetmanager .getappwidgetids(thisappwidget); int appwidgetid = intent.getintextra( appwidgetmanager.extra_appwidget_id, -1); // //////// remoteviews remoteviews = new remoteviews(context.getpackagename(), r.layout.widget); remoteviews.settextviewtext(r.id.btnesegui, configurazione.getname(context, "nome", appwidgetid)); // action code here appwidgetmanager.updateappwidget(appwidgetid, remoteviews); log.d("log_esecuzione", "log esecuzione, widget n." + string.valueof(appwidgetid)); } } then onupdate , updateappwidget method:
@override public void onupdate(context context, appwidgetmanager appwidgetmanager, int[] appwidgetids) { // todo auto-generated method stub // super.onupdate(context, appwidgetmanager, appwidgetids); final int n = appwidgetids.length; (int = 0; < n; i++) { int appwidgetid = appwidgetids[i]; updateappwidget(context, appwidgetmanager, appwidgetid); } } public static void updateappwidget(context context, appwidgetmanager appwidgetmanager,int appwidgetid){ //testonclick remoteviews remoteviews = new remoteviews(context.getpackagename(),r.layout.widget); intent myintent = new intent(context, controllowidget.class); myintent.setaction(action_widget_clicked); myintent.putextra(appwidgetmanager.extra_appwidget_id, appwidgetid); pendingintent pendingintent = pendingintent.getbroadcast(context,appwidgetid, myintent, 0); remoteviews.setonclickpendingintent(r.id.btnesegui, pendingintent); remoteviews.settextviewtext(r.id.btnesegui,configurazione.getname(context, "nome", appwidgetid)); //on update code, requested action when onupdate called (for widget), refresh pending intent appwidgetmanager.updateappwidget(appwidgetid, remoteviews); log.d("log_update", "log update, widget n."+string.valueof(appwidgetid)); } appwidgetmanager.updateappwidget(appwidgetid, remoteviews); } for separate instances necessary:
on intentcreation:(on updateappwidget)
remoteviews remoteviews = new remoteviews(context.getpackagename(),r.layout.widget); intent myintent = new intent(context, controllowidget.class); myintent.setaction(action_widget_clicked); //the line below appwidgetid specification myintent.putextra(appwidgetmanager.extra_appwidget_id, appwidgetid); pendingintent pendingintent = pendingintent.getbroadcast(context,appwidgetid, myintent, 0); remoteviews.setonclickpendingintent(r.id.btnesegui, pendingintent); on receiving broadcast: (on onreceive)
if (action_widget_clicked.equals(intent.getaction())){ //commented not used on example //appwidgetmanager appwidgetmanager = appwidgetmanager.getinstance(context); //componentname thisappwidget = new componentname(context.getpackagename(), controllowidget.class.getname()); //int[] appwidgetids = appwidgetmanager.getappwidgetids(thisappwidget); int appwidgetid = intent.getintextra(appwidgetmanager.extra_appwidget_id, -1); now call routine everywhere passing appwidgetid , context function... example:
action.someaction(context,appwidgetid); for update timer, possible (without using preferences): other intent use putextra on broadcast: retrieve int on broadcast receive
int appwidgetid = intent.getintextra(appwidgetmanager.extra_appwidget_id, -1); but don't call onupdate method directly updateappwidget alternative solution every widget has own time refresh (maybe configurable) i've preferred have 1 timer process active @ same time , widget updated @ first instance widget update time
