Question

我已在我的代码中添加了所有必需的配置以应用google plus身份验证。不幸的是，身份验证过程每次都返回handleSignInResult:false。我列出了我为google plus身份验证配置项目所做的所有步骤。

在项目级别gradle中，我添加了......

dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.google.gms:google-services:2.0.0-alpha3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

并在app level gradle中添加了

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.android.support:design:22.2.1'
    compile 'com.google.android.gms:play-services-auth:8.3.0'
    compile 'com.google.android.gms:play-services-identity:8.3.0'
    compile 'com.google.android.gms:play-services:8.3.0'
    compile 'com.facebook.android:facebook-android-sdk:4.+'
}
apply plugin: 'com.google.gms.google-services'

我的服务器客户端ID看起来像xxxxxxx-n7i6lyyyyyyyyy.apps.googleusercontent.com，我从 OAuth 2.0客户端ID

中找到了它

Web client 1    Mar 12, 2016    Web application     xxxxxxx-n7i6lyyyyyyyyy.apps.googleusercontent.com

我还在项目的应用目录中添加了 google-services.json /app

并将以下权限添加到项目清单

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

每次转到onConnectionFailed方法并返回handleSignInResult:false

@Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.d(TAG, "onConnectionFailed:" + connectionResult);
    }

我的项目默认使用gradle-2.10。所以，我使用的是gms：play-services：8.3.0而不是gms：play-services：8.4.0。

有谁能告诉我这里出了什么问题？

我也遇到了同样的问题，然后我更新了下面给出的代码，也可以在一些演示中找到

<div class="home-navigation">
        <a href="news.html"><div class="home-navigation-item"> NEWS </div></a>
        <a href="announcements.html"><div class="home-navigation-item"> ANNOUNCEMENTS </div></a>
        <a href="events.html"><div class="home-navigation-item"> SCHEDULE OF EVENTS</div></a>
</div>

并且也这样做

@Override
public void onConnectionFailed(ConnectionResult result) {
    if (!result.hasResolution()) {
        GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(), this,
                0).show();
        return;
    }

    if (!mIntentInProgress) {
        // Store the ConnectionResult for later usage
        mConnectionResult = result;

        if (mSignInClicked) {

            resolveSignInError();
        }
    }

    }


/**
 * Method to resolve any sign in errors
 * */
    private void resolveSignInError() {
    if (mConnectionResult.hasResolution()) {
        try {
            mIntentInProgress = true;
            mConnectionResult.startResolutionForResult(this, RC_SIGN_IN);
        } catch (SendIntentException e) {
            mIntentInProgress = false;
            mGoogleApiClient.connect();
        }
    }
}

如果你还没有这样做，试试这个

并检查是否已调用onActivityResult方法

无法在Android中实施google plus身份验证
