存储访问令牌，Google+ 集成 Android App

Question

我是 android 的新手，我开始从 android SDK 中的 GooglePlayServices 导入示例应用程序。 应用“Plus”允许我使用 G+ 凭据登录。示例代码使用 GoogleApiClient。

这仅在客户端验证应用程序。如何将访问令牌发送到我的服务器或将访问令牌存储到我的共享首选项？？

有人请解释我应该将访问令牌代码添加到哪个文件。？

我假设您能够成功登录 GooglePlus。执行以下操作以获取 AccessToken 并使用 SharedPreference 存储它，

SharedPreferences SharedPreference;    
Editor editor;

    private class GetGoogleAuthTask extends AsyncTask<Void, Void, String>  {
             @Override
             protected String doInBackground(Void... params) {
                 String token = null;

                 try {
                     token=GoogleAuthUtil.getToken(User_SignUp.this,Plus.AccountApi.getAccountName(mGoogleApiClient),"oauth2:"+Scopes.PLUS_LOGIN+" "+Scopes.PLUS_ME); //Change the permissions as per your need.
                 } catch (IOException transientEx) {
                     // Network or server error, try later
                     Log.e(TAG, transientEx.toString());
                 } catch (UserRecoverableAuthException e) {
                     // Recover (with e.getIntent())
                     Log.e(TAG, e.toString());
                    // Intent recover = e.getIntent();
                    // startActivityForResult(recover, REQUEST_CODE_TOKEN_AUTH);
                 } catch (GoogleAuthException authEx) {
                     // The call is not ever expected to succeed
                     // assuming you have already verified that 
                     // Google Play services is installed.
                     Log.e(TAG, authEx.toString());
                 }

                 return token;
             }

             @Override
             protected void onPostExecute(String token) {

                 if(token!=null)
                 {
                  Log.i(TAG, "Access token retrieved:" + token);
                  SharedPreference = getApplicationContext().getSharedPreferences("TokenPreference", 0); 
                  editor = SharedPreference.edit();
                  editor.putString("access_token",token);                               
                  editor.commit();                      

                 }

             }

         }

在需要获取accesstoken的地方使用sn-p，

new GetGoogleAuthTask().execute();
