AccountManager IllegalArgumentException: 键为空 [英] AccountManager IllegalArgumentException: key is null

问题描述

好的，我在不应该的地方收到了 IllegalArgumentException.

Ok, I'm getting an IllegalArgumentException at a point where it shouldn't.

我有一个使用 AccountManager 保存的 Account 自定义扩展:

I have a custom extension of Account that is saved using the AccountManager:

// Method inside a custom extension of Account
public boolean save(AccountManager manager) {
    removeAll(manager);
    boolean result = manager.addAccountExplicitly(this, null, toBundle());
    manager.setUserData(this, KEY_1, value1);
    manager.setUserData(this, KEY_2, value2);
    manager.setUserData(this, KEY_3, value3);
    return result;
}

键是常量字符串值，但应用程序仍然抛出:

The keys are constant String values but app still throws:

java.lang.IllegalArgumentException: key is null

我不得不说我只是以这种方式附加用户数据，因为使用:

I have to say that I'm only attaching the user data in this fashion because using:

 manager.addAccountExplicitly(this, null, toBundle());

似乎没有附加值.键是否需要特殊的名称模式?

didn't seem to attach the values. Do the keys require a special name pattern?

有人遇到过这个问题吗?

Anybody had this problem before?

更新:

它被抛出到 manager.setUserData() 里面，看起来像这样(Android 代码):

It gets thrown inside the manager.setUserData() which looks like this (Android code):

public void setUserData(final Account account, final String key, final String value) {
    if (account == null) throw new IllegalArgumentException("account is null");
    if (key == null) throw new IllegalArgumentException("key is null");
    try {
        mService.setUserData(account, key, value);
    } catch (RemoteException e) {
        // won't ever happen
        throw new RuntimeException(e);
    }
}

当我用 Eclipse走进"这个方法时，我在调试角度得到了这个:

When I "walk" into this method with eclipse I get this in the debug perspective:

值不为空 >o<

推荐答案

好的，经过进一步研究 的 AccountManager 我没有找到让它像我尝试的那样工作的方法，但我找到了一个解决方案.

Ok, after further research into 's AccountManager I did not find a way to make it work like I was trying but I found a solution.

我没有将详细信息保存为用户数据包，而是使用密钥作为 authTokenType 将它们保存为 authToken 值，如下所示:

Instead of saving the details as an user data bundle I save them as authToken values using the key as the authTokenType like this:

public boolean save(AccountManager manager) {
    removeAll(manager);
    boolean result = manager.addAccountExplicitly(this, null, toBundle());
    manager.setAuthToken(this, KEY_1, value1);
    manager.setAuthToken(this, KEY_2, value2);
    manager.setAuthToken(this, KEY_3, value3);
    return result;
}

然后像这样检索值:

value1 = manager.peekAuthToken(account, KEY_1);

我仍然不确定这是否是为 Account 存储数据的方式，但这是我迄今为止唯一成功的方法.

I'm still not sure if this is the way to store data for an Account but it's the only one I've managed to make work so far.
