Plus.PeopleApi.getCurrentPerson()返回null，仅此而已

Question

我搜索了很多，但仍然没有得到解决方案。Plus.PeopleApi.getCurrentPerson()总是返回null。我得到了我的调试SHA1和释放SHA1。它们都作为带有适当包名的OAuth 2.0客户端id添加到控制台。(遗憾的是，我不能发布图片)这是我的GoogleApiClient:

    private GoogleApiClient buildGoogleApiClient() {
    return new GoogleApiClient.Builder(getContext())
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Plus.API)
            .addScope(new Scope(Scopes.PROFILE))
            .addScope(new Scope(Scopes.PLUS_LOGIN))
            .build();
}

相当简单。我从Fragment的onCreateView()调用它。然后我试着找到当前的人:

@Override
public void onConnected(Bundle bundle) {
    Plus.PeopleApi.loadVisible(mGoogleApiClient, null).setResultCallback(this);
    if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
        Person currentPerson = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
        String personName = currentPerson.getDisplayName();
        String personGooglePlusProfile = currentPerson.getUrl();
    }

总是null。mGoogleApiClient工作很好，它连接，它不是空的，但仍然。在控制台-> API中启用了Google+ API，但在"用法"选项卡中没有任何请求。

我已经尝试了所有我能找到的解决方案，没有任何帮助。我运行的应用程序与根模拟器。请帮帮我，给我一些建议。

添加:这是我几乎完整的片段类:

            } else {

            </intent-filter>
        </activity>
</manifest>

对编辑错误表示抱歉

Answer 1

我找到了解决方案。它不是关于片段和SHA1密钥。这是关于包的名字。当我创建项目时，IDE将包目录设置为"somepackage"。App"，这不是我需要的，我把它改成了"somepackage"。一切都很好，除了谷歌api。Gradle在它的配置文件中保存了"applicationId somepackage"。App"，我相信它会覆盖manifest的包名。没有错误，没有连接，什么都没有。我花了大约15个小时，我相信我很笨。

Answer 2

将此添加到onCreateView()之上

private GoogleApiClient mGoogleApiClient;

onCreateView()中

        mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .addApi(Plus.API, Plus.PlusOptions.builder().build())
        .addScope(Plus.SCOPE_PLUS_LOGIN).build();

onConnected()中

@Override
public void onConnected(Bundle bundle) {
      getProfileInformation();
    }

并添加这个方法

public void getProfileInformation() {
    try {
        if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
            Person currentPerson = Plus.PeopleApi
                    .getCurrentPerson(mGoogleApiClient);
            String name = currentPerson.getDisplayName();
            String email = Plus.AccountApi.getAccountName(mGoogleApiClient);
        } else {
            Toast.makeText(getActivity(),
                    "Person information is null", Toast.LENGTH_LONG).show();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

别忘了实现

ConnectionCallbacks, OnConnectionFailedListener

将此元数据添加到Manifest.xml中的标签application

下

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

Try this manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="somepackage" >
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.USE_CREDENTIALS" />
    <application
        android:allowBackup="true"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
      <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
</manifest>

Answer 3

此外，在@Kotsu关于确保包名正确的出色提示之上。还要确保它在https://developers.google.com/mobile/add?platform=android&cntapi=signin&cnturl=https:%2F%2Fdevelopers.google.com%2Fidentity%2Fsign-in%2Fandroid%2Fsign-in%3Fconfigured%3Dtrue&cntlbl=Continue%20Adding%20Sign-In

上也是正确的

这里有谷歌服务。Json文件为您生成。这是指定AppName和包名的地方。希望这有助于有人以及它帮助了我，当我也得到了一个null从getCurrentPerson返回。
