android - Howto get GoogleDrive Quota(remaining available size) with GoogleApiClient? -


i use googleapiclient on android app. can not googledrive quota usage(total/available/etc..). googling..., may driveservice(com.google.api.services.drive.drive) possible... not use that......

how googledrive quota info?

(note) here googleapiclient builder.

gdapi = new googleapiclient.builder(mcontext)                 .addapi(plus.api)                 .addscope(plus.scope_plus_profile)                 .addapi(drive.api)                 .addscope(drive.scope_file)                 .addconnectioncallbacks(this)                 .addonconnectionfailedlistener(this)                 .setaccountname(token)                 .build();

unfortunately (afaik), there no equivalent of getquotabytestotal(), getquotabytesused() in gdaa.

so, way info (and other functionalities not present - thumbnails, ...), add rest api. still, sure use mix carefully, may run many latency / timing issues.

there few pre-requisites accomplishing this:

1/ make sure include following jars in project:

compile 'com.google.apis:google-api-services-drive:v2-rev105-1.17.0-rc' compile 'com.google.http-client:google-http-client-gson:1.20.0' compile 'com.google.api-client:google-api-client-android:1.20.0' ... import com.google.api.client.extensions.android.http.androidhttp; import com.google.api.client.googleapis.extensions.android.gms.auth.googleaccountcredential; import com.google.api.client.json.gson.gsonfactory;

2/ need additional permission in manifest:

  <uses-permission android:name="android.permission.get_accounts" />

3/ have com.google.api.services.drive.drive service , query after gdaa's onconnected() callback, so:

private static googleapiclient mgac; private static com.google.api.services.drive.drive mgoosvc;  static boolean init(activity context) {   if (context != null) try {      mgoosvc = new com.google.api.services.drive.drive.builder(       androidhttp.newcompatibletransport(),       new gsonfactory(),       googleaccountcredential.usingoauth2(         context.getapplicationcontext(),         collections.singletonlist(com.google.api.services.drive.drivescopes.drive_file)       )     ).build();      mgac = new googleapiclient.builder(context)       .addapi(drive.api)       // ... additional apis       .addscope(drive.scope_file)       .addconnectioncallbacks(new googleapiclient.connectioncallbacks() {         @override         public void onconnectionsuspended(int i) {         }          @override         public void onconnected(bundle bundle) {           new thread(new runnable() {             @override             public void run() {               try {                 com.google.api.services.drive.model.about = mgoosvc.about().get().execute();                 system.out.println("total quota (bytes): " + about.getquotabytestotal());                 system.out.println("used quota (bytes): " + about.getquotabytesused());               } catch (exception e) { e.printstacktrace(); }               //} catch (userrecoverableauthioexception uraioex) {               //  // standard authorization failure - user fixable               //} catch (googleauthioexception gaioex) {               //  // packagename /sha1 mismatch in devconsole               //} catch (ioexception e) {               //  if (e instanceof googlejsonresponseexception) {               //    if (404 == ((googlejsonresponseexception) e).getstatuscode()) {               //      // '404 not found' in file scope, consider connected               //    }               //  }               //} catch (exception e) {               //  // "the name must not empty" indicate               //  // unregistered / empty account in 'setselectedaccountname()' above               //}             }           }).start();         }       })       .addonconnectionfailedlistener(new googleapiclient.onconnectionfailedlistener() {         @override         public void onconnectionfailed(@nonnull connectionresult rslt) {           // perform standard authorization dance         }       })       .build();      mgac.connect();      return true;     } catch (exception e) {e.printstacktrace();}   return false; }

notice, commented out error / authorization handling rest's execute() method. because gdaa's connect()/onconnected()/onconnectionfailed() handles authorization (if scopes identical).

good luck

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

ruby on rails - Seeing duplicate requests handled with Unicorn -

recently upgraded our ec2 instances c3.large in order boost more unicorn workers handle increased traffic our site. (6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
