android - Always get 401 log in required from Gmail API -

-

ok, had working @ 1 point, wanted add silent login (optional) @ app startup. going crazy , getting following error

com.google.api.client.googleapis.json.googlejsonresponseexception: 401 unauthorized { "code": 401, "errors": [ { "domain": "global", "location": "authorization", "locationtype": "header", "message": "login required", "reason": "required" } ], "message": "login required" }

this occurs on line (should using "me"?)

message messageresult = mgmailservice.users().messages().send("me", message).execute();

whenever try send (in case above) or read email (not shown). ultimately, want app read user emails , send on behalf. app registered, has keys, permissions, etc.

i setting data (you can see various comments tried things working):

    mgso = new googlesigninoptions.builder(googlesigninoptions.default_sign_in)             .requestemail()             .requestscopes(new scope(scopes.profile))             .requestscopes(new scope(gmailscopes.gmail_readonly))             .requestscopes(new scope(gmailscopes.gmail_send))             .requestscopes(new scope(gmailscopes.gmail_compose))             .requestscopes(new scope(gmailscopes.gmail_labels))             .requestscopes(plus.scope_plus_login)             .requestscopes(new scope(scopes.email))             .requestscopes(new scope(scopes.plus_me))             .build();      // set google client //        mgoogleapiclient = new googleapiclient.builder(this) //                .addconnectioncallbacks(this) //                .addonconnectionfailedlistener(this) //                .addapi(plus.api) //                .addapi(auth.google_sign_in_api, mgso) //                .build();     mgoogleapiclient = new googleapiclient.builder(this)     //        .enableautomanage(this, this)             .addconnectioncallbacks(this)             .addonconnectionfailedlistener(this)             .addapi(plus.api)             .addapi(auth.google_sign_in_api, mgso)             .build();      //mgoogleapiclient.connect(googleapiclient.sign_in_mode_required); // try connect right away      mgmailservice = new com.google.api.services.gmail.gmail.builder(             androidhttp.newcompatibletransport(), gsonfactory.getdefaultinstance(), null)             .setapplicationname("com.company.appname")             .build();

the silent login done in onstart() method of embedded fragment as:

    // try silently sign in ...     optionalpendingresult<googlesigninresult> pendingresult =             auth.googlesigninapi.silentsignin(mgoogleapiclient);      if (pendingresult.isdone()) {         // there's immediate result available.         msigninacct = pendingresult.get().getsigninaccount();         memailacct = msigninacct.getemail();     } else {         // there's no immediate result ready, wait async callback.         pendingresult.setresultcallback(new resultcallback<googlesigninresult>() {             @override             public void onresult(@nonnull googlesigninresult result) {                 msigninacct = result.getsigninaccount();                 memailacct = msigninacct.getemail();             } // if fails, forget , force real login later.         });     }      mgoogleapiclient.connect(googleapiclient.sign_in_mode_optional);     boolean b = mgoogleapiclient.isconnected();

which connects right away valid user account , not. see b ...isconnected() call false, although isconnected() returns true later in later calls.

login button code:

        gmail_signin_button = (com.google.android.gms.common.signinbutton) rootview.findviewbyid(r.id.gmail_sign_in_button);         gmail_signin_button.setscopes(mgso.getscopearray());         gmail_signin_button.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 // user clicked sign-in button, begin sign-in process , automatically                 // attempt resolve errors occur.                 mshouldresolve = true;                  // connect if unconnected...                 if (!mgoogleapiclient.isconnected()) {                     mgoogleapiclient.connect();                      tv_email_status.settext("g+ connecting");                     // show message user signing in.                     log.d(constants.tag, "google api connecting ...");                 }                 else {                     // sign in anew ...                     intent signinintent = auth.googlesigninapi.getsigninintent(mgoogleapiclient);                     startactivityforresult(signinintent, constants.rc_sign_in);                 }             }         });

onactivityresult code (in part):

    public void onactivityresult(int requestcode, int resultcode, intent data) {         super.onactivityresult(requestcode, resultcode, data);          // g+         if (requestcode == constants.rc_sign_in) {             // if error resolution not successful should not resolve further.              googlesigninresult result = auth.googlesigninapi.getsigninresultfromintent(data);              if (!result.issuccess()) {                 mshouldresolve = false;                 log.d(constants.tag, "error: code: " + resultcode);                 tv_email_status.settext("error: code: " + resultcode);             } else {                 msigninacct = result.getsigninaccount();                 memailacct = msigninacct.getemail();                 log.d(constants.tag, "gmail signin ok - " + memailacct);                 tv_email_status.settext("email: " + memailacct);             }              misresolving = false;             if(!mgoogleapiclient.isconnected()) {                 mgoogleapiclient.connect(googleapiclient.sign_in_mode_optional);             }          } else if (requestcode == constants.request_account_picker) {             if (resultcode == result_ok && data != null && data.getextras() != null) {                 memailacct = data.getstringextra(accountmanager.key_account_name);                 if (memailacct != null) {                     //mcredential.setselectedaccountname(accountname);                     sharedpreferences settings = mactivity.getpreferences(context.mode_private);                     sharedpreferences.editor editor = settings.edit();                     editor.putstring(constants.pref_account_name, memailacct);                     editor.commit();                      log.d(constants.tag, "gmail: account: " + memailacct);                     tv_email_status.settext("gmail: account: " + memailacct);                  }             } else if (resultcode == result_canceled) {                 tv_email_status.settext("account unspecified.");             }         }         //else if (requestcode == constants.request_authorization) {             //if (mcredential != null && resultcode != result_ok) {             //    startactivityforresult(mcredential.newchooseaccountintent(), constants.request_account_picker);             //}         //}

ok, onactivityresult , valid signinacct , emailacct values. it seems logged in fine, gmail service fails 401 error explained above.

to silent login made me have add google_sign_in_api seems require googleapiclient connect sign_in_mode_optional doesn't make sense me.

i see accountpicker nothing well. story/problem, said thought had working until tried add silent feature.

whew, have made harder is, can steer me in right direction? said want is:

  1. silently log in if user has done so
  2. allow user log in or re-log in if needed
  3. read users emails , contacts
  4. send email on behalf.

ok, figured out, usual simple wrong. credential in gmailservice constructor must set, don't have until try connect. have code this

void setgmailaccess(googlesigninresult result) {     msigninacct = result.getsigninaccount();     memailacct = msigninacct.getemail();      final thread task = new thread()     {         @override         public void run()         {             try {                 // run in background thread                 string token = googleauthutil.gettoken(mainactivity.this, plus.accountapi.getaccountname(mgoogleapiclient), "oauth2:profile email");                 googlecredential credential = new googlecredential().setaccesstoken(token);                 mgmailservice = new com.google.api.services.gmail.gmail.builder(                         androidhttp.newcompatibletransport(), gsonfactory.getdefaultinstance(), credential)                         .setapplicationname("com.company.appname")                         .build();             }             catch (exception e) {                 // ignore errors                 string error = e.getmessage();             }         }     };      task.start();  }

to set gmailservice object. called onconnected, have code in result success block:

    try {          // try silently sign in ...         optionalpendingresult<googlesigninresult> pendingresult =                 auth.googlesigninapi.silentsignin(mgoogleapiclient);          if (pendingresult.isdone()) {             // there's immediate result available.             setgmailaccess(pendingresult.get());          } else {             // there's no immediate result ready, wait async callback.             pendingresult.setresultcallback(new resultcallback<googlesigninresult>() {                 @override                 public void onresult(@nonnull googlesigninresult result) {                     setgmailaccess(result);                 } // if fails, forget , force real login later.             });         }     } catch(exception e) {         string me = e.getlocalizedmessage();     }

and in activity result starting new login. seems work.

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
