android - Google-plus：无法加载人员

Question

我想在我的应用程序中登录 Google Plus。我可以连接但无法获取当前用户的个人资料信息

@Override
public void onConnected() {

    String accountName = mPlusClient.getAccountName();

    mPlusClient.loadPerson(this, "me");
}

@Override
public void onPersonLoaded(ConnectionResult status, Person person) {

    Log.d("onPersonLoaded - ConnectionResult", "" + status);
    Log.d("onPersonLoaded - person", "" + person);
    if (status.getErrorCode() == ConnectionResult.SUCCESS) {
        Log.d(TAG, "Display Name: " + person.getDisplayName());
    }
}

我可以在onConnected但onPersonLoaded给出null的帐户名称person

日志显示：

onPersonLoaded - ConnectionResult(29861): ConnectionResult{statusCode=NETWORK_ERROR, resolution=null}
onPersonLoaded - person(29861): null

从这里的文档

公共静态最终 int NETWORK_ERROR

发生网络错误。重试应该可以解决问题。

常数值：7 (0x00000007)

但是无论我重试多少次，我都会得到同样的错误。这些是我使用的权限：

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

我不知道如何解决这个问题，并且一直在寻找过去 2 个小时。任何帮助都非常感谢，谢谢。

Answer 1

最后我找到了答案。:)

loadPerson()并且loadPeople()只会在使用有效密钥签名的导出 APK 中返回您预期的数据。这里有效是指它应该与 SHAI 和您的API 密钥控制台的其他规范相匹配。

遵循示例代码时您可能会错过的另一件事是在 PlusClient 构造函数中定义范围，例如

mPlusClient = new PlusClient.Builder(this, this, this).setScopes(Scopes.PLUS_LOGIN)
                .setVisibleActivities("http://schemas.google.com/AddActivity").build();

private class connectAsyncTask extends AsyncTask<String, Void, String> {

    String sAccessToken = null;

    @Override
    protected void onPostExecute(String info) {

        Log.d("JSONData = ", "" + info);
        //This contains all the data you wanted.
    }

    @Override
    protected String doInBackground(String... params) {

        HttpURLConnection urlConnection = null;
        try {
            URL url = new URL(
                    "https://www.googleapis.com/oauth2/v1/userinfo");

            //This is probably not the right way to do.
            //What I am doing here is, get an AccessToken, invalidate it and get a new
            //AccessToken again. Because I couldn't find a way to check whether the 
            //AccessToken is expired or not.

            GoogleAuthUtil.invalidateToken(MainActivity.this, sAccessToken);

            sAccessToken = GoogleAuthUtil

        } catch (FileNotFoundException e) {
            //You get this exception when the AccessToken is expired.
            //I don't know how its a FileNotFoundException
