1.申请权限
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
PermissionsUtil.checkAndRequestPermissions(this);
2.FileProvider存储配置
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
xml/file_paths
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_Files" path="."/>
</paths>
