java - Best way to store array persistently in Android without using SQLite -


i have array in android application store when application closed , later restore when application opened again. know 1 stores larger amounts of data in android in sqlite database. have arrays i'd store. therefore know best method doing is.

best means following me:

  • good performance

  • easy, non-complicated code

  • able t store multi-dimensional arrays , arraylists

the following possibilities i've come with:

  • json

  • xml

  • metaprogramming store array in text file initialize , read using metaprogramming. it's not easy, doable in java.

though of course in not exhaustive list. best way store array in java according criteria above?

i know not typical q/a quenstion think have provided clear criteria , examples, doesn't violate stackoverflow "question rules"

there 4 basic methods data storage in android.

  1. internal storage- private folder can write files to. can write small file there, , read back.
  2. external storage- same internal, except other applications can see it. sd card. useful large data sets don't want in internal limited memory, , don't mind sharing (mp3's, images, etc)
  3. sqlite database- best large sets of data in tabular type format.
  4. shared preferences- best small amounts of data, use store preference values, maybe high scores, etc. doesn't natively store arrays, store json string, mentioned possibility.

for storing set of high scores, used internal storage folder, seemed work enough purposes. once choose method, should able figure out how write/get data appropriately. if can't, feel free ask question figure piece out.

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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