二、解决方案

配置 FileProvider ,

使用 androidx 支持库的情况 :

<manifest>
    ...
    <application>
        ...
        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="com.mydomain.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>
        ...
    </application>
</manifest>

或使用 support 支持库的情况 :

<manifest>
    ...
    <application>
        ...
        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="com.mydomain.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
        </provider>
        ...
    </application>
</manifest>

file_paths.xml 文件配置 : 下面的配置将所有的文件设置为可分享的文件 , 具体还要根据需求自己定制 ;

<paths 
    xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external" path="." />
    <external-files-path name="external_files" path="." />
    <cache-path name="cache" path="." />
    <external-cache-path name="external_cache" path="." />
    <files-path name="files" path="." />
</paths>
