Android Google+登录无效 - statusCode = SIGN_IN_REQUIRED

Question

我想让用户使用Google+登录.我在Google开发者控制台中创建了该项目,我获得了客户端ID,并在Android Studio中安装了Google Play服务.(我的运行设备有Android 4.4.2)当应用程序运行时我按下登录按钮会出现一个Toast消息:"Internal Error"

Logcat中的错误如下:

error ConnectionResult{statusCode=SIGN_IN_REQUIRED, resolution=PendingIntent{429ffe38: android.os.BinderProxy@429ffdd8}}

请注意,在用户按下按钮之前出现此错误,事实上,通过调试,我发现它来自此行代码:

Log.e(TAG, "error " + result.toString());

在方法中:

public void onConnectionFailed(ConnectionResult result) {
    if (!mGoogleIntentInProgress) {
        /* Store the ConnectionResult so that we can use it later when the user clicks on the Google+ login button */
        mGoogleConnectionResult = result;

        if (mGoogleLoginClicked) {
            /* The user has already clicked login so we attempt to resolve all errors until the user is signed in,
             * or they cancel. */
            resolveSignInError();
        } else {
            Log.e(TAG, "error " + result.toString());
        }
    }
}

这里有其他重要的方法:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    SignInButton googleLoginButton = (SignInButton) findViewById(R.id.login_with_google);
    googleLoginButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mGoogleLoginClicked = true;
            if (!mGoogleApiClient.isConnecting()) {
                if (mGoogleConnectionResult != null) {
                    resolveSignInError();
                } else if (mGoogleApiClient.isConnected()) {
                    getGoogleOAuthTokenAndLogin();
                } else {
                /* connect API now */
                    Log.d(TAG, "Trying to connect to Google API");
                    mGoogleApiClient.connect();
                }
            }
        }

    });

    /* Setup the Google API object to allow Google+ logins */
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Plus.API)
            .addScope(Plus.SCOPE_PLUS_LOGIN)
            .build();
}

 private void resolveSignInError() {
    if (mGoogleConnectionResult.hasResolution()) {
        try {
            mGoogleIntentInProgress = true;
            mGoogleConnectionResult.startResolutionForResult(this, RC_GOOGLE_LOGIN);
        } catch (IntentSender.SendIntentException e) {
            // The intent was canceled before it was sent.  Return to the default
            // state and attempt to connect to get an updated ConnectionResult.
            mGoogleIntentInProgress = false;
            mGoogleApiClient.connect();
        }
    }
}

 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_GOOGLE_LOGIN) {
        /* This was a request by the Google API */
        if (resultCode != RESULT_OK) {
            mGoogleLoginClicked = false;
        }
        mGoogleIntentInProgress = false;
        if (!mGoogleApiClient.isConnecting()) {
            mGoogleApiClient.connect();
        }
    }


}

这里是AndroidManifest.xml中的代码

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

和元数据

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

希望你能帮助我,非常感谢!

与我的项目一样,Google+登录时存在许多问题.例如,创建时mGoogleApiClient,您应该这样做

           mGoogleApiClient = new GoogleApiClient.Builder(this) 
                .addApi(Plus.API) 
                .addScope(Plus.SCOPE_PLUS_LOGIN) 
                .addScope(Plus.SCOPE_PLUS_PROFILE) 
                .addConnectionCallbacks(this) 
                .addOnConnectionFailedListener(this) 
                .build();

使用SCOPE_PLUS_PROFILE - OAuth 2.0范围访问用户的Google+个人资料数据.

您需要启用Google+ API并使用SHA1和您的包创建凭据.

OAuth同意屏幕,包含您的电子邮件和产品名称 (必填)

更多的,请确认:

的applicationID在标签<应用程序>
的包名在AndroidManifest.xml
包名在谷歌开发者控制台凭证

所有相同


更多,请确保您拥有权限:

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

更多,方法 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data { ... ... }

不要需要调用super.onActivityResult(requestCode,resultCode为,数据);

更重要的是:调试密钥库和发布密钥库.

和更多 .....
