无法找到< custom provider>的提供商信息 [英] Failed to find provider info for <custom provider>

问题描述

我有一个简单的应用程序，从<$ c $开始在 AndroidManifest.xml 中正确定义了 MainActivity ，my Content Provider code> ContentProvider 类似乎alrighty ...这已经测试了运行4.3的nexus i9250和运行4.2.1的Asus Memo Pad以及运行Jelly Bean的VDevices。应用程序运行在每个实例，不会崩溃， LogCat 给我的唯一的事情是无法找到de.somename.provider的提供者信息在我的一个片段尝试查询内容提供程序并获取游标的点。这里的代码：

解决方案

 < provider android：authorities = .somename.provider
 android：enabled =true
 android：multiprocess =true
 android：name =hvkContentProvider
 android：exported =true >< / provider> 
 

从< provider> ：链接

android：authorities： ......为避免
冲突，权限名称应使用Java风格的命名约定
（例如 com.example.provider.cartoonprovider ）。通常，它是实现提供程序的ContentProvider子类的
名称。

在您的情况下， android：authorities 应该具有值： de.somename.provider.hvkContentProvider 。

< hr>

android：name： ......实现内容的类的名称
provider，ContentProvider的子类。这应该是完全
限定类名（例如，
com.example.project.TransportationProvider）。但是，作为
速记，如果名称的第一个字符是句点，它是
附加到元素中指定的包名。

所以，如果你在清单 package $ c>标签 AndroidManifest.xml ，请确保该包中包含 hvkContentProvider 。 Else，change android：name =。hvkContentProvider到 android：name =de.somename.hvk3.hvkContentProvider或 your.package.name.hvkContentProvider

I have read just about everything there is to find here on this issue, not getting past this.

I have a simple app starting with the MainActivity, my Content Provider is correctly defined in AndroidManifest.xml, the ContentProvider class seems alrighty...this has been tested on a nexus i9250 running 4.3 and an Asus Memo Pad running 4.2.1 as well as VDevices running Jelly Bean. The App runs in every instance and does not crash, the only thing the LogCat gives me is "Failed to find provider info for de.somename.provider" at the point where one of my fragments tries to query the Content Provider and get a cursor. Here the Code:

The Method: insertSomeFunctions() i have left out since it doesn't make a difference here, gonna put a bounty on this asap. Really need to get this done.

解决方案

<provider android:authorities="de.somename.provider"
    android:enabled="true"
    android:multiprocess="true"
    android:name=".hvkContentProvider"
    android:exported="true" ></provider>

From reference page on <provider>: Link

android:authorities: ......To avoid conflicts, authority names should use a Java-style naming convention (such as com.example.provider.cartoonprovider). Typically, it's the name of the ContentProvider subclass that implements the provider.

In your case, android:authorities should have the value: de.somename.provider.hvkContentProvider.

---

android:name:...... The name of the class that implements the content provider, a subclass of ContentProvider. This should be a fully qualified class name (such as, "com.example.project.TransportationProvider"). However, as a shorthand, if the first character of the name is a period, it is appended to the package name specified in the element.

So, if you are defining package in the manifest tag of AndroidManifest.xml, make sure hvkContentProvider is in that package. Else, change android:name=".hvkContentProvider" to android:name="de.somename.hvk3.hvkContentProvider" or your.package.name.hvkContentProvider
