notifyactivitystate pkg:

最近接到一个国外项目要实现 Facebook twitter google+的第三方登陆本来打算使用sharesdk的但是这个第三方插件支持 facebook和twitter，但是在google上总是出现问题，无奈只能选择google的api实现。google的说明文档纯英文你们都懂得花费好久终于研究通了不敢独享就拿出来给大家分享下。

我这里使用的开发工具是IDEA 下面就是步骤了

上图是原理下面就是干货步骤

首先在google developer console创建一个专案

输入专案名建议和你的项目名一致

之后要填写同意书

这一步比较关键套件名称就是项目包名 SHA1密码你可以自己生成，用keytool工具来生成最后这个秘钥放在这个位置同时你项目也要绑定秘钥。

最后千万别忘了开启google+服务的api接口我之前就是忘了总是获取不到登陆后的用户信息。

这里准备工作只进行了一部分还有下载最新版本的 google服务包，通过android manager下载。然后导入google play services lib文件然后将它加到你的项目的dependency中

最后就是代码工作了

在androidmanifest中

  1 
 
 2

  <meta-data android:name="com.google.android.gms.version" 
 
     android:value="@integer/google_play_services_version" /> 

然后是main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<com.google.android.gms.common.SignInButton
android:id="@+id/sign_in_button"
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>

最后是activity

package com.example.TrueLife.view;

import android.app.Activity;
import android.content.Intent;
import android.content.IntentSender.SendIntentException;
