Question

我的目标是开发一款可以与朋友一起测验音乐的游戏。您可以通过注册此Google+社区自行测试： https://plus.google.com/u/0/communities/100815426127955231967

我正在几台设备上测试我的应用程序：

摩托罗拉Xoom，android 4.1.2，构建JZO54K
Nexus 7 2012 Wifi＆＃34; nagasi＆＃34;，android 5.0.2，构建LRX22G
Nexus 5，android 5.0.1，构建LRX22C

我在所有设备上使用相同的Google用户。我的应用已注册，我在清单文件中包含了正确的行。

使用完全相同的代码，我可以成功连接到Nexus 7和Nexus 5棒棒糖设备上的Google Plus和游戏服务，但不能在Xoom android 4设备上连接。

以下是代码，连接请求位于Activity onCreate：

中

@Override
protected void onCreate(Bundle savedInstanceState) {
if (GooglePlayServicesUtil.isGooglePlayServicesAvailable(this) == ConnectionResult.SUCCESS) {
        if (mGoogleApiClient == null) {
            Plus.PlusOptions plusOptions = new Plus.PlusOptions.Builder().addActivityTypes(
               "http://schemas.google.com/AddActivity", "http://schemas.google.com/ReviewActivity").build();
            mGoogleApiClient = new GoogleApiClient.Builder(this).addApi(Games.API).addScope(Games.SCOPE_GAMES)
               .addApi(Plus.API, plusOptions).addScope(Plus.SCOPE_PLUS_LOGIN)
               .addConnectionCallbacks(this).addOnConnectionFailedListener(this).build();
        }
        mGoogleApiClient.connect();
    } else {
        Toast.makeText(this, R.string.texteErreurGPlus, Toast.LENGTH_LONG).show();
    }
}

对于Android 4设备，将使用以下消息调用onConnectionFailed回调：

GoogleApiClient connection failed: ConnectionResult{statusCode=SIGN_IN_REQUIRED, resolution=PendingIntent{412f07c8: android.os.BinderProxy@413b0bd0}} :


@Override
public void onConnectionFailed(ConnectionResult result) {
    if (mResolvingConnectionFailure) {
        // Already resolving
        return;
    } else if (result.hasResolution()) {
        try {
            mResolvingConnectionFailure = true;
            result.startResolutionForResult(this, REQUEST_CODE_RESOLUTION);
        } catch (SendIntentException e) {
            // There was an error with the resolution intent. Try again.
            mGoogleApiClient.connect();
        }
    } else {
        // Show dialog using GooglePlayServicesUtil.getErrorDialog()
        showErrorDialog(result.getErrorCode());
        mResolvingConnectionFailure = true;
    }
}

这导致活动onActivityResult：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case REQUEST_CODE_RESOLUTION:
            mResolvingConnectionFailure = false;
            if (resultCode == RESULT_OK) {
                // Make sure the app is not already connected or attempting to connect
                if (!mGoogleApiClient.isConnecting() &&
                        !mGoogleApiClient.isConnected()) {
                    mGoogleApiClient.connect();
                }
            } else {
                mGoogleApiClient.connect();
            }
            break;

和无限循环，因为resultCode不等于RESULT_OK。

以下是Android Studio的gradle文件：

apply plugin: 'android'

android {
    compileSdkVersion 21
    buildToolsVersion '21.1.2'

    defaultConfig {
        applicationId "debut.blindtest"
        minSdkVersion 16
        targetSdkVersion 21
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
    }

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile project(':volley')
    compile 'com.android.support:appcompat-v7:21.0.2'
    compile 'com.google.android.gms:play-services-plus:6.5.+'
    compile 'com.google.android.gms:play-services-games:6.5.+'
    compile files('libs/deezer-sdk-0.10.16.jar')
}

执行流程为：

主要活动onCreate，其中称为GoogleApiClient连接
调用onConnectionFailed主要活动，结果有解析，因此调用result.startResolutionForResult
主要活动onActivityResult被称为

你能帮助我发现我应该做些什么来与Android 4设备兼容吗？

Answer 1

通过在onConnectionFailed()中自动连接，您将会根据需要继续尝试连接多次，直到获得有效连接为止。这意味着即使用户不想登录（例如，他们在登录对话框中点击取消），也会不断地反复提示他们。

相反，Google+ Sign In guide使用mSignInClicked变量来帮助确定onConnectionFailed()是否应该立即重新连接（未连接的人的理想情况是onConnectionFailed()被调用但是您尚未拨打startResolutionForResult() - 只需保存ConnectionResult，直到用户登录为止。

如果您想要保留初始自动登录尝试，可以考虑Google Play Games Services samples中使用的方法，例如TrivialQuest，onConnnectionFailed()方法如下所示：

public void onConnectionFailed(ConnectionResult connectionResult) {
  Log.d(TAG, "onConnectionFailed() called, result: " + connectionResult);

  if (mResolvingConnectionFailure) {
    Log.d(TAG, "onConnectionFailed() ignoring connection failure; already resolving.");
    return;
  }

  if (mSignInClicked || mAutoStartSignInFlow) {
    mAutoStartSignInFlow = false;
    mSignInClicked = false;
    mResolvingConnectionFailure = BaseGameUtils.resolveConnectionFailure(this, 
        mGoogleApiClient, connectionResult, RC_SIGN_IN, 
        getString(R.string.signin_other_error));
  }
  showSignInBar();
}

他们使用BaseGameUtils辅助方法更轻松地连接到Google服务（注意：没有特别的游戏服务相关 - 它与所有GoogleApiClient个连接同样有效。）< / p>

Answer 2

我删除了行＆＃34; android：launchMode =＆＃34; singleInstance＆＃34;＆＃34;在我的清单文件中。经过几次构建/运行循环后，它开始工作。我只需要重新设计我的应用程序来改变我的活动。

Answer 3

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" />

Google+在Android 4上登录时出现statusCode = SIGN_IN_REQUIRED错误
