Android AccountManager.getUserData（）返回null [英] Android AccountManager.getUserData() returns null

问题描述

我有类似的问题，如 AccountManager getUserData返回null尽管它正在设置但解决方案对我不起作用

I have a similar problem like this AccountManager getUserData returning null despite it being set But the solutions did not work for me

My Authenticator.java

My Authenticator.java

public class Authenticator extends AbstractAccountAuthenticator{

    private Context context;
    public Authenticator(Context context) {
        super(context);
        this.context = context;
    }

    @Override
    public Bundle editProperties(AccountAuthenticatorResponse response,
            String accountType) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public Bundle addAccount(AccountAuthenticatorResponse response,
            String accountType, String authTokenType,
            String[] requiredFeatures, Bundle options)
            throws NetworkErrorException {
        Bundle result = new Bundle();
        Intent intent = new Intent(context,LoginActivity.class);
        intent.putExtra(AccountManager.KEY_ACCOUNT_TYPE, accountType);
        intent.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE, response);
        result.putParcelable(AccountManager.KEY_INTENT, intent);
        return result;
    }

    @Override
    public Bundle confirmCredentials(AccountAuthenticatorResponse response,
            Account account, Bundle options) throws NetworkErrorException {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public Bundle getAuthToken(AccountAuthenticatorResponse response,
            Account account, String authTokenType, Bundle options)
            throws NetworkErrorException {

        return null;
    }

    @Override
    public String getAuthTokenLabel(String authTokenType) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public Bundle updateCredentials(AccountAuthenticatorResponse response,
            Account account, String authTokenType, Bundle options)
            throws NetworkErrorException {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public Bundle hasFeatures(AccountAuthenticatorResponse response,
            Account account, String[] features) throws NetworkErrorException {

        return null;
    }

}

我添加了一个这样的帐户

I added an account like this

mAccount = new Account("SalesGenie", "com.ambertag.salesgenie.ACCOUNT"); 
mAccountManager.addAccountExplicitly(mAccount, password, userData);

但是当我尝试通过调用获取用户数据时getUserData（）我得到了空白

But when I try to get user data by calling getUserData() I get null

推荐答案

有一个更简单的解决方案：

There is a much simpler solution:

请勿使用 addAccountExplicitly（Account，String，Bundle） 。相反，只需传递一个空包并使用 setUserData（帐户，字符串，字符串） 在您创建之后添加用户数据帐户 addAccountExplicitly 。

Don't add the user-data with addAccountExplicitly(Account, String, Bundle). Instead, just pass an empty bundle and use setUserData(Account, String, String) to add the user-data after you created the account with addAccountExplicitly.

它可能不太方便，但它会确保用户 - 数据缓存已正确填充，不会返回 null 。

It may be a little less convenient, but it will make sure that the user-data cache is populated properly and won't return null.
