找不到' ContentProvider'的提供商信息 [英] Failed to find provider info for 'ContentProvider'

问题描述

我有一个我无法解决的问题.我正在使用Eclipse创建自己的内容提供程序，但始终收到以下错误:

I have a problem that I just cannot figure out. I am using Eclipse to create my own Content Provider but keep getting the following error:

[..]错误/ActivityThread(1051):无法找到提供程序的信息my.package.provider.countrycontentprovider

[..] ERROR/ActivityThread(1051): Failed to find provider info for my.package.provider.countrycontentprovider

在此处找到代码: http://codepad.org/Rx00HjHd

主要部分:

public class CountryContentProvider extends ContentProvider {

    public static final String PROVIDER = 
         "my.package.provider.countrycontentprovider";
    public static final Uri CONTENT_URI = 
         Uri.parse("content://" + PROVIDER + "/country");
    // ...
    @Override
    public boolean onCreate() { return true; }
    // ...
}


// from my activity
ContentResolver resolver = getContentResolver();
Cursor c = resolver.query(CountryContentProvider.CONTENT_URI, 
                                  null, null, null, null);  

// AndroidManifest.xml
<provider
    android:name="my.package.provider.CountryContentProvider"
    android:authorities="my.package.provider.countrycontentprovider" />

我已将提供程序添加到清单中，并从 onCreate 函数返回true.我在活动中使用 CountryContentProvider.CONTENT_URI 从提供商处获取内容，但我一直在获取该错误消息.我已删除并添加了3次代码(以防日食融化)，但无济于事.
我肯定错过了什么.有人可以指出我正确的方向吗?

I have added the provider to the manifest and return true from the onCreate function. I use the CountryContentProvider.CONTENT_URI in my activity to get the Content from my provider, but I just keep getting that error message. I have removed and added the code three times (in case of eclipse melt down) to no avail.
I must be missing something. Can someone point me in the right direction?

推荐答案

当我将< provider>从< application> ...</application>标记中移出时，我能够重现您的问题.Eclipse没有说任何错误或警告.

I was able to reproduce your problem when I moved <provider> out of the <application>...</application> tag. Eclipse didn't say anything like error or warning.

幸运的是，从ADT 20开始，Android Lint可以检测到此问题.

Fortunately this issue is detected by Android Lint starting from ADT 20.
