1.準備工作
首先得在谷歌開發(fā)控制臺https://console.developers.google.com 創(chuàng)建自己的項目，并配好相關(guān)的信息，如圖

2.在你的project的gradle注入谷歌服務的依賴 classpath 'com.google.gms:google-services:3.0.0'

然后在你的app的gradle中加入compile 'com.google.android.gms:play-services-auth:9.6.1'依賴， 并在最底部引入apply plugin: 'com.google.gms.google-services'

記得在app目錄下的加入google-services.json文件

好了，配置基本完成，接下來就是在你的登陸頁面擼登陸的代碼了
1.初始化Google 可以參考谷歌官方api https://developers.google.com/+/mobile/android/getting-started
/**
* Google登錄初始化
*/
public void initGooglePlus() {
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestId()
.requestProfile()
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
}
點擊登陸按鈕
/**
* 登陸
*/
public void googleSignIn() {
Intent intent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(intent, G_SIGN_IN);
}
回調(diào)
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == G_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
}
}
獲取回調(diào)返回的用戶相關(guān)信息
/**
* Google plus 登陸回調(diào)
*/
private void handleSignInResult(GoogleSignInResult result) {
showLog("handleSignInResult----" + result.isSuccess());
if (result.isSuccess()) {
GoogleSignInAccount account = result.getSignInAccount();
showLog("id--------" + account.getId() + "----name----" + account.getDisplayName() + "---photo--" + account.getPhotoUrl());
}
}
好了，簡單的完成google登陸了，不過還有退出等邏輯，這里就不寫了
