二、解决方案

---

配置 FileProvider ,

使用 androidx 支持库的情况 :

<manifest>...<application>...<providerandroid:name="androidx.core.content.FileProvider"android:authorities="com.mydomain.fileprovider"android:exported="false"android:grantUriPermissions="true"><meta-dataandroid: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>...<providerandroid:name="android.support.v4.content.FileProvider"android:authorities="com.mydomain.fileprovider"android:exported="false"android:grantUriPermissions="true"><meta-dataandroid: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>
