android - Scheduled sync adapter runs every 30 seconds -


i use sync adapters in application sync changes server periodically. no matter value put in pollfrequency sync runs every 30 seconds.

i checked on forum , tried changes suggested in replies , pass 'false' synctonetwork parameter when raise notifychange on contentresolver.

on going through training again in detail, stumbled upon difference.

on google developer site -> training section sync adapters training see addperiodicsync -> pollfrequency parameter passed in milliseconds 

public class mainactivity extends fragmentactivity { ... // constants // content provider authority public static final string authority = "com.example.android.datasync.provider";  // account public static final string account = "default_account";  // sync interval constants public static final long milliseconds_per_second = 1000l; public static final long seconds_per_minute = 60l; public static final long sync_interval_in_minutes = 60l;  //this line i'm referring public static final long sync_interval = sync_interval_in_minutes *                                           seconds_per_minute *                                          milliseconds_per_second;  // global variables // content resolver accessing provider contentresolver mresolver; ... @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     ...     // content resolver app     mresolver = getcontentresolver();     /*      * turn on periodic syncing      */     contentresolver.addperiodicsync(             account,             authority,             null,             sync_interval);     ...     }     ... }

on api reference api reference pollfrequency mentioned in seconds. expected unit pollfrequency, milliseconds or seconds? appreciated.

you should add contentresolver.setmastersyncautomatically(true); code. without setsyncautomatically ignored.

read documentation here.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
