I got a problem using google plus is that if any body had a google account but not activated its google plus account then what can I do in that case?

I want google sign in that way is there any way please give me solutions as soon as possible .


Hi you can use following approach: First of all, ask user to enter email Id say in editText and get that value on click of some button, and proceed like below:

//Check whether account is already configured or not


        if(isAccountAlreadyConfigured(emailId)){
    //If the email id entered by user is already configured in the device
                                getGoogleApiClientInstance(emailId);
                                connectToGoogleApiClient();
                            }else{
    //If that email id account is not configured in the 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 is used to check whether the email address entered by user is already
             * configured in the device or not
             * @param String: it takes the email address as the 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 this for confirmCredentialsMethod
                            return true;
                        }
                Log.i(LOG_TAG, "Account info: "+account.name + "\n" + "Account type: "+account.type);
                }
                return false;
            }

        /* @method getGoogleApiClientInstance is used to get GoogleApiClientInstance for a particular google account

            private GoogleApiClient getGoogleApiClientInstance(String accountName){

                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .setAccountName(accountName)
                .build();

                return mGoogleApiClient;
            }

        /* @method connectToGoogleApiClient is used to connect GoogleApiClient instance to Google API servers */
                private void connectToGoogleApiClient(){            

                    if(mGoogleApiClient != null){

                    }       
                }

    /* accountManagerCallback is used to pass as one of  the params to 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 will block until the result is available so we call it on another 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 and accountType as the extras, this acts as a confirmation that
                      the account is properly configured in the device or we can cross verify by 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 you can use below code if you don't want to use GoogleApiClient instance for already 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 is of type Account class which you can retrieve from isAccountAlreadyConfiguredMethod.
