location - Android O - Old start foreground service still working? -


so, android o, need have service running foreground service if want receive more few location updates per hour.

i noticed old method starting foreground service seem work on o. i.e. 

startforeground(notification_id, getnotification());

according behaviour changes guide here: https://developer.android.com/preview/behavior-changes.html

"the notificationmanager.startserviceinforeground() method starts foreground service. old way start foreground service no longer works."

though new method works when targeting o, seems old method still seems work on o device whether targeting o or not. missing something?

//edit including example:

the google sample project locationupdatesforegroundservice has working example can see issue first hand. https://github.com/googlesamples/android-play-location/tree/master/locationupdatesforegroundservice

the startforeground method seems work without issue whether targeting , compiling against api level 25 or targeting , compiling against o (as directed here: https://developer.android.com/preview/migration.html#uya)

so, reproduce:

  1. configure app gradle mentioned in previous link
  2. open app
  3. request location updates
  4. close app (either via button or home button)

service running in foreground (shown icon in notification shade). location updates coming through expected (every 10 seconds) on device running o.

this makes me think may missing something.

usually start service broadcast receiver using startservice. saying it's no more possible (or reliable) call startservice because there background limitations, need call startserviceinforeground instead. docs it's not clear when happens because app whitelisted when receives broadcast intent, it's not clear when startservice throws illegalstateexception.

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
