Second, create a new folder inside add a xml xml file name in the directory, such as res: file_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">


    <root-path
        name="root"
        path="." />
    <files-path
        name="files"
        path="." />
    <cache-path
        name="cache"
        path="/"/>
    <external-path
        name="external"
        path="." />
    <external-cache-path
        name="external_cache"
        path="." />
    <external-files-path
        name="external_file"
        path="." />

</paths>

 

Element must contain one or a plurality of sub-elements. These sub-element is used to specify the directory path to share files, you must be one of these elements:

<Files-path>: internal storage application files / directories under the private directory, equivalent to Context.getFilesDir () acquired directory path;

<Cache-path>: internal storage application cache / private directory under the directory is equivalent to Context.getCacheDir (acquired directory path);

<External-path>: external storage root, equivalent to Environment.getExternalStorageDirectory () acquired directory path;

<External-files-path>: external storage application files / directories under the private directory, the directory path is equivalent to Context.getExternalFilesDir (null) acquired;

<External-cache-path>: Application of external storage cache / private directory under the directory, equivalent to Context.getExternalCacheDir ();

 

Add in the application

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

 

AndroidManifest.xml configured through the storage rights;

<application
        android:requestLegacyExternalStorage="true">
