Android 应用程序集成Google 登录及二次封装

2017-05-16 14:42 549 查看

谷歌登录API： https://developers.google.com/identity/sign-in/android/

1、注册并且登录google网站

https://accounts.google.com/

2、进入google开发者平台创建应用

https://developers.google.com/mobile/add?platform=android&cntapi=signin&cntapp=Default%20Demo%20App&cntpkg=com.google.samples.quickstart.signin&cnturl=https:%2F%2Fdevelopers.google.com%2Fidentity%2Fsign-in%2Fandroid%2Fstart%3Fconfigured%3Dtrue&cntlbl=Continue%20with%20Try%20Sign-In

3、在开发者平台填写响应的信息，包括应用名、包名、签名的SHA-1值

4、在项目中添加谷歌服务

4.1、在SDK Manager 里面下载 google service

4.2、在project目录下的build.gradle下添加

classpath 'com.google.gms:google-services:2.1.0-alpha4'

查看最新版本号：https://jcenter.bintray.com/com/google/gms/google-services/

4.3 在model目录下的build.gradle下添加

compile 'com.google.android.gms:play-services-auth:8.4.0'

5、代码实现

5.1、在布局文件中

1  <com.google.android.gms.common.SignInButton
2             android:id="@+id/google_signIn_bt"
3             android:layout_width="wrap_content"
4             android:layout_height="wrap_content" />
5
6         <Button
7             android:id="@+id/google_loginOut_bt"
8             android:layout_width="match_parent"
9             android:layout_height="wrap_content"
10             android:text="google退出登录"
11             android:layout_gravity="center"
12             android:gravity="center"
13             >
14         </Button>

5.2、java代码

1 package com.pegasus.map.presentation.ui.activity;

38                 .requestProfile()
39                 .build();

54         activity.startActivityForResult(signInIntent, requestCode);
55     }
56
57     /**

60     public void signOut() {
61         Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
62                 new ResultCallback<Status>() {
63                     @Override
64                     public void onResult(Status status) {
65                         if ( status.isSuccess() ){
66                             if ( googleSignListener != null ){
67                                 googleSignListener.googleLogoutSuccess();
68                             }
69                         }else {
70                             if ( googleSignListener!= null ){
71                                 googleSignListener.googleLogoutFail();
72                             }
73                         }
74                     }
75                 });
76     }
77
78     public String handleSignInResult(GoogleSignInResult result) {
79         String res = "" ;
80         if (result.isSuccess()) {
81             //登录成功
82             GoogleSignInAccount acct = result.getSignInAccount();
83             res = "登录成功"
84                     + "用户名为：" + acct.getDisplayName()
85                     + "  邮箱为：" + acct.getEmail()
86                     + " token为：" + acct.getIdToken()
87                     + " 头像地址为：" + acct.getPhotoUrl()
88                     + " Id为：" + acct.getId()
89                     + " GrantedScopes为：" + acct.getGrantedScopes() ;
90             Log.e("res", "res:"+res);
91             Toast.makeText( activity, res, Toast.LENGTH_SHORT).show();
92             if ( googleSignListener != null ){
93                 googleSignListener.googleLoginSuccess();
94             }
95         } else {
96             // Signed out, show unauthenticated UI.
97             res = "-1" ;  //-1代表用户退出登录了 ， 可以自定义
98             Toast.makeText( activity , "退出登录", Toast.LENGTH_SHORT).show();
99             if ( googleSignListener != null ){
100                 googleSignListener.googleLoginFail();
101             }
102         }
103         return res ;
104     }
105
106
107     public void setGoogleSignListener( GoogleSignListener googleSignListener ){
108         this.googleSignListener = googleSignListener ;
109     }
110
111     public interface GoogleSignListener {
112         void googleLoginSuccess();
113         void googleLoginFail() ;
114         void googleLogoutSuccess();
115         void googleLogoutFail() ;
116     }
117
118 }

注意：当你把 GoogleLogin 类复制到你项目中的时候，activity.getString(R.string.google_server_client_id) 这一句会报错，可以先不用管，在6.5 部分会做说明

6.1 在activity里使用封装类

activity 实现 GoogleApiClient.OnConnectionFailedListener , GoogleLogin.GoogleSignListener 两个接口

6.2

//初始化谷歌登录服务
GoogleLogin googleLogin = new GoogleLogin( this , this ) ;
googleLogin.setGoogleSignListener(this);

6.3

1     @Override
2     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
3         super.onActivityResult(requestCode, resultCode, data);
4
5         //谷歌登录成功回调
6         if (requestCode == googleLogin.requestCode ) {
7             GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
8             googleLogin.handleSignInResult( result ) ;
9         }
10     }

6.4

1 //登录
2 googleLogin.signIn();
3
4  //退出
5 googleLogin.signOut();

6.5 获取 google_server_client_id ，并在strings 里面配置

https://console.developers.google.com/projectselector/apis/credentials

在上面的网站里选择

点击选择项目，然后选择你创建的app，进入下面一个界面，得到对应的Client ID

补充：（2016/8/9）

有很多人留言或者发私信说一直登陆失败。然后我就自己写了一个demo，核心代码完全复制博客里面的 GoogleLogin (代码见第六个标题， 6、Google SDK 二次封装) 里面的代码，真的是一行代码都没有改,完完全全复制的。最后实现登陆成功，可见博客里面的代码是没有问题的。我在操作过程中，有几个关键的地方提一下。

1、权限问题

只需要添加联网权限即可   <uses-permission android:name="android.permission.INTERNET"></uses-permission>

2、签名问题

在开发者后台创建app的时候，需要添加 SHA-1的值，这个值是从你的签名里面获取的。注意，在你运行demo的时候，如果直接运行是不行的，因为直接运行，android studio 会为你的app使用默认签名，这个签名是系统自带的，这个签名的SHA-1值肯定和你真正的签名文件SHA-1值不一样，所以必然会登录失败。你需要修改你的app debug 时的签名和发布时的签名一直就好了。
