java - How to get battery level -


i trying battery level of mobile using adf. mean example if battery charged fifty want value.

how can achieve this?

i don't know can achieve using android-intent.

if yes, have do?

here code sample explains how battery information: http://www.tutorialforandroid.com/2009/01/getting-battery-information-on-android.html

to sum up, broadcast receiver action_battery_changed intent set dynamically, because can not received through components declared in manifests, explicitly registering context.registerreceiver().

public class main extends activity {   private textview batterytxt;   private broadcastreceiver mbatinforeceiver = new broadcastreceiver(){     @override     public void onreceive(context ctxt, intent intent) {       int level = intent.getintextra(batterymanager.extra_level, 0);       batterytxt.settext(string.valueof(level) + "%");     }   };    @override   public void oncreate(bundle b) {     super.oncreate(b);     setcontentview(r.layout.main);     contenttxt = (textview) this.findviewbyid(r.id.batterytxt);     this.registerreceiver(this.mbatinforeceiver, new intentfilter(intent.action_battery_changed));   } }

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
