如果你有不同的风格，你想避免在权威名称上的冲突，你可以添加一个applicationIdSuffix来构建类型，并在你的清单中使用结果的applicationId，如下所示:

<...
 android:authorities="${applicationId}.contentprovider"/>

        need to use android:name="androidx.core.content.contentprovider 
        or android:name="androidx.core.content.provider insteadof 
        android:name="androidx.core.content.fileprovider

        <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.contentprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/filepaths" />
    </provider>

就像@Jose L Ugia所说的那样，让当局做出改变。

(您可以在清单中找到提供者(合并清单))

大多数情况下，它会连接到你实现的SDK，所以删除SDK实现行并同步Gradle，然后再次添加实现行并同步Gradle。

实施路线: 实现文件(<您的SDK>)

提供者代码:(你必须在merge-manifest中向下滚动才能找到它)

如果你在Xamarin上，你得到这个错误(可能是因为Firebase.Crashlytics):

INSTALL_FAILED_CONFLICTING_PROVIDER
Package couldn't be installed in [...]
Can't install because provider name dollar_openBracket_applicationId_closeBracket (in package [...]]) is already used by [...]

正如这里提到的，你需要更新Xamarin.Build.Download:

Update the Xamarin.Build.Download Nuget Package to 0.4.12-preview3 On Mac, you may need to check Show pre-release packages in the Add Packages window Close Visual Studio Delete all cached locations of NuGet Packages: On Windows, open Visual Studio but not the solution: Tools -> Option -> Nuget Package Manager -> General -> Clear All Nuget Cache(s) On Mac, wipe the following folders: ~/.local/share/NuGet ~/.nuget/packages packages folder in solution Delete bin/obj folders in solution Load the Solution Restore Nuget Packages for the Solution (should run automatically) Rebuild

如果你正在使用受众网络内容提供者，你需要在你的应用程序AndroidManifest.xml中添加这段代码

<provider
        android:name="com.facebook.FacebookContentProvider"
        android:authorities="com.facebook.app.FacebookContentProvider165632208074623"
        android:exported="true" />

你的Facebook应用id是> 165632208074623

可能是您在清单中声明的授权机构+提供者名称
