尝试在Android中添加帐户时获取例外
作者：互联网
我正在尝试为用户创建一种在手机上创建帐户的方法,该帐户最终会通过应用程序同步到他们的联系人.我现在正在模拟器中工作,所以我要去Menu-Dev Tools-AccountsTester来测试我拥有的东西.当我单击AccountsTester时,我在LogCat中收到以下错误代码：

正如您所看到的,没有@ line显示我的代码中发生错误的位置.我谷歌搜索了一些突出的线路,但找不到与我的问题有关的任何内容.有没有人知道这里发生了什么？如果您有任何信息可以用来帮助解答我没有包含的内容,请告诉我…谢谢！

我没有在那里调用单个字符串…我的活动引用了几次字符串,但它引用的字符串肯定在那里,当我输入它时我看到它们,并且我无论如何都会在Eclipse中收到错误.
解决方法:
这里的诀窍是,在我创建帐户所需的xml / authenticator文件中,我用“App Name”填充了android：label字段,如下所示：
android:label="App Here"
我需要做的是为它调用一个资源.所以我创建了一个名为label的字符串并将名称放在那里,它工作正常.
