hi can use following approach: first of all, ask user enter email id in edittext , value on click of button, , proceed below:

//check whether account configured or not           if(isaccountalreadyconfigured(emailid)){     //if email id entered user configured in device                                 getgoogleapiclientinstance(emailid);                                 connecttogoogleapiclient();                             }else{     //if email id account not configured in device                                 bundle accountoptions = new bundle();                                 accountoptions.putstring(accountmanager.key_account_name, emailid);                                 accountoptions.putstring(accountmanager.key_account_type,constants.account_type);                                 accountmanager.addaccount(constants.account_type, null, null, accountoptions, this, accountmanagercallback, null);                             }          /* @method isaccountalreadyconfigured used check whether email address entered user              * configured in device or not              * @param string: takes email address parameter              * @return boolean*/             private boolean isaccountalreadyconfigured(string accountname){                 account[] accounts = accountmanager.getaccountsbytype(constants.account_type);                 for(account account: accounts ){                         if(account.name.equals(accountname)){ //account alreadyconfiguredaccount = account; //use confirmcredentialsmethod                             return true;                         }                 log.i(log_tag, "account info: "+account.name + "\n" + "account type: "+account.type);                 }                 return false;             }          /* @method getgoogleapiclientinstance used googleapiclientinstance particular google account              * @param string : gmail account id              * @return googleapiclient instance               * */             private googleapiclient getgoogleapiclientinstance(string accountname){                 mgoogleapiclient = new googleapiclient.builder(this)                 .addapi(plus.api)                 .addscope(plus.scope_plus_login)                 .addconnectioncallbacks(this)                 .addonconnectionfailedlistener(this)                 .setaccountname(accountname)                 .build();                  return mgoogleapiclient;             }          /* @method connecttogoogleapiclient used connect googleapiclient instance google api servers */                 private void connecttogoogleapiclient(){                                  if(mgoogleapiclient != null){                         mgoogleapiclient.connect();                     }else{                         log.e(log_tag, "error connecting google api client");                     }                        }      /* accountmanagercallback used pass 1 of  params accountmanager.addaccount method*/         private accountmanagercallback<bundle> accountmanagercallback = new accountmanagercallback<bundle>() {              @override             public void run(accountmanagerfuture<bundle> future) {                 futurebundle = future;                 log.i(log_tag, "done: " +future.isdone() + "\n" + "iscancelled: "+future.iscancelled());                         handler.post(runnable);             }         };          private runnable runnable = new runnable() {              @override             public void run() {              try {                 // futurebundle.getresult() call block until result available call on thread                 bundle bundle = futurebundle.getresult();                 if(bundle != null){                     log.i(log_tag, "result: "+bundle);                     string authaccount = bundle.getstring(accountmanager.key_account_name);                     string accounttype = bundle.getstring(accountmanager.key_account_type);                      /*result bundle should have authaccount , accounttype extras, acts confirmation                       account configured in device or can cross verify calling                       @method isaccountalreadyconfigured*/                      if((authaccount.equals(emailid) && accounttype.equals(constants.account_type)) || isaccountalreadyconfigured(emailid)){                         getgoogleapiclientinstance(emailid);                         connecttogoogleapiclient();                     }else{                                       log.e(log_tag, "an error occured while configuring new account");                     }                 }                        } catch (operationcanceledexception e) {                 e.printstacktrace();             } catch (authenticatorexception e) {                         e.printstacktrace();             } catch (ioexception e) {                        e.printstacktrace();             }              }         }; 

or can use below code if don't want use googleapiclient instance configured account ie. above if

if(isaccountalreadyconfigured(emailid)){  bundle accountoptions = new bundle();                             accountoptions.putstring(accountmanager.key_account_name, emailid);                             accountoptions.putstring(accountmanager.key_account_type,"com.google");                             accountmanager.confirmcredentials(account, accountoptions, this, accountmanagercallback, null); } 

first parameter account of type account class can retrieve isaccountalreadyconfiguredmethod.
