最新更新（2020/4/15）

最新有個項目要集成 google 登陸，我又又又又重新做了一遍，發現很多重要 api 都變了，這里重新總結一下，用 Kotlin 編寫。

首先依賴包已經更新到 18.0.0

 api 'com.google.android.gms:play-services-auth:18.0.0'

GoogleLoginUtil 工具類：

package com.enjoy.literaturemodule.account.login.google

import android.content.Context import androidx.fragment.app.FragmentActivity import com.enjoy.library.utils.LogUtils import com.enjoy.literaturemodule.R import com.google.android.gms.auth.api.signin.* import com.google.android.gms.common.api.ApiException import com.google.android.gms.tasks.Task /** * @author yanjun.zhao * @time 2020/4/15 3:20 PM * @desc Google 登陸 */ class GoogleLoginUtil(var activity: FragmentActivity, private var googleSignListener: GoogleSignListener) { private var gso: GoogleSignInOptions? = null private var mGoogleSignClient: GoogleSignInClient? = null companion object { const val requestCode = 10 } init { gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestEmail() .requestId() .requestIdToken(activity.getString(R.string.google_server_client_id)) .requestProfile() .build() mGoogleSignClient = GoogleSignIn.getClient(activity, gso!!) } /** * 登陸 */ fun login() { var intent = mGoogleSignClient?.signInIntent activity.startActivityForResult(intent, requestCode) } /** * 退出登陸 */ fun signOut() { mGoogleSignClient?.signOut() ?.addOnCompleteListener { googleSignListener?.googleLogoutSuccess() } ?.addOnFailureListener { googleSignListener?.googleLogoutFail() } } /** * 是否 登陸過 */ fun hasLogin(context: Context): Boolean { var accout = GoogleSignIn.getLastSignedInAccount(context) if (accout == null) { //是新用戶，沒有登陸過 return false } else { //老用戶，已經登陸過 //獲取用戶信息 var displayName = accout?.displayName var email = accout?.email val id = accout?.id val photoUrl = accout?.photoUrl val familyName = accout?.familyName val givenName = accout?.givenName return true } } fun handleSignInResult(completedTask: Task<GoogleSignInAccount>) { try { var accout = completedTask.getResult(ApiException::class.java) //登陸成功 var displayName = accout?.displayName var email = accout?.email val id = accout?.id val photoUrl = accout?.photoUrl val familyName = accout?.familyName val givenName = accout?.givenName LogUtils.d("google-displayName", displayName) LogUtils.d("google-email", email) LogUtils.d("google-photoUrl", photoUrl?.encodedPath) LogUtils.d("google-photoUrl", photoUrl?.toString()) LogUtils.d("google-familyName", familyName) LogUtils.d("google-givenName", givenName) LogUtils.d("google-id", id) googleSignListener?.googleLoginSuccess() } catch (e: ApiException) { googleSignListener?.googleLoginFail() } } interface GoogleSignListener { fun googleLoginSuccess() fun googleLoginFail() fun googleLogoutSuccess() fun googleLogoutFail() } }

Activity 使用

package com.enjoy.literaturemodule.account

import android.content.Intent import android.os.Bundle import android.util.Log import androidx.fragment.app.FragmentActivity import com.enjoy.literaturemodule.account.login.google.GoogleLoginUtil import com.google.android.gms.auth.api.signin.GoogleSignIn import kotlinx.android.synthetic.main.activity_login.* /** * 登陸 */ class LoginActivity : FragmentActivity(), GoogleLoginUtil.GoogleSignListener { private var googleLoginUtil: GoogleLoginUtil? = null override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) googleLoginUtil = GoogleLoginUtil(this, this) //登陸  google_signIn_bt.setOnClickListener { googleLoginUtil?.login() } } override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { //google登陸 if (requestCode == GoogleLoginUtil.requestCode) { var googleResultTask = GoogleSignIn.getSignedInAccountFromIntent(data) googleLoginUtil?.handleSignInResult(googleResultTask) } super.onActivityResult(requestCode, resultCode, data) } override fun googleLoginSuccess() { Log.e("google", "googleLoginSuccess") } override fun googleLoginFail() { Log.e("google", "googleLoginFail") } override fun googleLogoutSuccess() { Log.e("google", "googleLogoutSuccess") } override fun googleLogoutFail() { Log.e("google", "googleLogoutFail") } }

在做的時候，發現一直登陸不成功 StatusCode = 12500 , 折騰了很久，才弄好，有兩點需要注意：

注意事項1：

一旦添加了 google_server_client_id ，那么客戶端 google-services.json 一定要更新。

注意事項2：

項目集成 Google 登陸，一定要在 Firebase 后台開啟 Google 登陸功能，一定、一定、一定。

開啟之前的狀態

開啟之后的狀態：

補充：（2016/8/9）

有很多人留言或者發私信說一直登陸失敗。然后我就自己寫了一個demo，核心代碼完全復制博客里面的 GoogleLogin (代碼見第六個標題， 6、Google SDK 二次封裝) 里面的代碼，真的是一行代碼都沒有改,完完全全復制的。最后實現登陸成功，可見博客里面的代碼是沒有問題的。我在操作過程中，有幾個關鍵的地方提一下。

1、權限問題：只需要添加聯網權限即可

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

2、簽名問題

在開發者后台創建app的時候，需要添加 SHA-1的值，這個值是從你的簽名里面獲取的。注意，在你運行demo的時候，如果直接運行是不行的，因為直接運行，android studio 會為你的app使用默認簽名，這個簽名是系統自帶的，這個簽名的SHA-1值肯定和你真正的簽名文件SHA-1值不一樣，所以必然會登錄失敗。你需要修改你的app debug 時的簽名和發布時的簽名一致就好了。

正文：

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

1、注冊並且登錄google網站

https://accounts.google.com/

2、進入google開發者平台創建應用

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、在開發者平台填寫響應的信息，包括應用名、包名、簽名的SHA-1值

圖3

4、在項目中添加谷歌服務

4.1、在SDK Manager 里面下載 google service

4.2、在project目錄下的build.gradle下添加

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

4.3 在model目錄下的build.gradle下添加

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

5、代碼實現

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退出登錄"
11             android:layout_gravity="center"
12             android:gravity="center"
13             >
14         </Button>

5.2、java代碼

 69                         }else {
 70                             if ( googleSignListener!= null ){
 71                                 googleSignListener.googleLogoutFail();
 72                             }
 73                         }
 74                     }
 75                 });
 76     }
 77 
 78     public String handleSignInResult(GoogleSignInResult result) {
 79         String res = "" ;

 88                     + " Id為：" + acct.getId()
 89                     + " GrantedScopes為：" + 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代表用戶退出登錄了 ， 可以自定義
 98             Toast.makeText( activity , "退出登錄", Toast.LENGTH_SHORT).show();
 99             if ( googleSignListener != null ){
100                 googleSignListener.googleLoginFail();

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：當你把 GoogleLogin 類復制到你項目中的時候，activity.getString(R.string.google_server_client_id) 這一句會報錯，可以先不用管，在6.5 部分會做說明

6.1 在activity里使用封裝類

activity 實現 GoogleApiClient.OnConnectionFailedListener , GoogleLogin.GoogleSignListener 兩個接口

6.2

 //初始化谷歌登錄服務
 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         //谷歌登錄成功回調
 6         if (requestCode == googleLogin.requestCode ) {
 7             GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
 8             googleLogin.handleSignInResult( result ) ;
 9         }
10     }

6.4

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

6.5 獲取 google_server_client_id ，並在strings 里面配置

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

在上面的網站里選擇

點擊選擇項目，然后選擇你創建的app，進入下面一個界面，得到對應的Client ID
