Android - Application onCreate method - does it ALWAYS get called first? -


i preparing new version of 1 of apps, , made such huge changes in app, need data conversion after update of app absolutely first thing (before doing else). figured out, best place in class (which extends application) in oncreate() method. tested few times, , seems work ok, read documentation:

base class need maintain global application state. can provide own implementation specifying name in androidmanifest.xml's tag, [b]which cause class instantiated when process application/package created[/b].

it looks right, not quite sure. can confirm/disprove it?

the application constructor called first. application::oncreate() method called. exception know of if application contains contentprovider, can receive calls before application does.

this here: http://developer.android.com/reference/android/app/application.html#oncreate()

public void oncreate ()

added in api level 1 called when application starting, before activity, service, or receiver objects (excluding content providers) have been created. implementations should quick possible (for example using lazy initialization of state) since time spent in function directly impacts performance of starting first activity, service, or receiver in process. if override method, sure call super.oncreate().

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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
