Android open .docx file via ContentResolver in QuickOffice crashes -


for reason code opening downloaded file, , in instance .docx not work quickoffice, exception i'm getting this:

06-02 22:04:05.356: e/androidruntime(2889): fatal exception: main 06-02 22:04:05.356: e/androidruntime(2889): process: com.quickoffice.android, pid: 2889 06-02 22:04:05.356: e/androidruntime(2889): java.lang.nullpointerexception 06-02 22:04:05.356: e/androidruntime(2889): @ com.google.android.apps.docs.quickoffice.a.g.a(abstractsaveaction.java:14) 06-02 22:04:05.356: e/androidruntime(2889): @ com.google.android.apps.docs.editors.menu.d.a(abstractmenuitemcontroller.java:28) 06-02 22:04:05.356: e/androidruntime(2889): @ com.google.android.apps.docs.editors.menu.c.a(abstractbuttonmenuitemcontroller.java:24) 06-02 22:04:05.356: e/androidruntime(2889): @ com.google.android.apps.docs.editors.menu.y.a(menucontroller.java:59) 06-02 22:04:05.356: e/androidruntime(2889): @ com.google.android.apps.docs.editors.menu.y.a(menucontroller.java:59) 06-02 22:04:05.356: e/androidruntime(2889): @ com.google.android.apps.docs.editors.menu.z.run(menucontroller.java:37)

my code establishing intent is:

intent install = new intent(intent.action_view); string mimetype = getmimetype(tempfile);  uri uri = uri.parse("content://com.companyname/"+ filename); install.setdataandtype(uri, mimetype); install.setflags(intent.flag_activity_no_history);  intent intent = intent.createchooser(install, "open file");   _progressdialog.getcontext().startactivity(intent);

my content provider code is:

    public class downloadedfilecontentprovider extends contentprovider {          @override         public parcelfiledescriptor openfile(uri uri, string mode) throws filenotfoundexception {         file privatefile = new file(getcontext().getcachedir(), uri.getpath());         return parcelfiledescriptor.open(privatefile, parcelfiledescriptor.mode_read_write);         }             //other overridden methods return false , null contentprovider class.      }

i'm out of ideas, case microsoft office on android, document doesn't open @ all. office suite application opens everything.

i did below

            file file = new file(filepath);             intent intent = new intent(intent.action_view);             mimetypemap mimetypemap = mimetypemap.getsingleton();             string fileextension = filepath.substring(filepath.lastindexof(".") + 1);             fileextension = fileextension.tolowercase();             if(mimetypemap.getmimetypefromextension(fileextension) != null) {                 string type = mimetypemap.getmimetypefromextension(fileextension);                  if(istablet(activity))                 {                     if(fileextension.equals("txt"))                     {                         intent.setdataandtype(uri.fromfile(file), "text/plain");    //changed uri.parse(fp, type) method                     }                     else                     {                         intent.setdataandtype(uri.fromfile(file), type);                     }                 }                 else                 {                     intent.setdataandtype(uri.fromfile(file), type);                 }                                     try{                     activity.startactivityforresult(intent, constants.request_authentication_completed);                 }catch(android.content.activitynotfoundexception e){                     system.out.println("exception : "+e.getlocalizedmessage());                 }                                }

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
