ZXing android use front camera -


i'm trying build qr code reader following tutorial

http://code.tutsplus.com/tutorials/android-sdk-create-a-barcode-reader--mobile-17162

i managed working, except need camera front camera of device instead of rear camera. can't find place in tutorial allows me change this. tried following this answer, still not work.

mainly, issue importing library. following error.

operator not allowed source level below 1.7

when set compiler settings 1.7, this

android requires compiler compliance level 5.0 or 6.0. found '1.7' instead

i'm not proficient android , apologize if might not question.

so, way me use zxing front camera in app? links?

thank much.

the source code uses java 7. android not require java <= 6. can see build provided in project happily feeds java 7 bytecode dex , produces working app. not sure tool using suggests otherwise. maybe old.

you should not need copy , compile project's code though. why necessary? use core.jar file.

you don't need of use front camera. invoke intent (https://github.com/zxing/zxing/wiki/scanning-via-intent) , set scan_camera_id id of camera want -- 1 front one.

example:

        intent.putextra("scan_mode", "qr_code_mode");         intent.putextra("scan_camera_id", 1);

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
