- 在AndroidManifest文件的application標籤下添加如下內容:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="你的包名.fileProvider"
android:grantUriPermissions="true"
android:exported="false">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
- 2.在res目錄下新建xml資源目錄,並新建file_paths文件:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<!--
path:需要臨時授權訪問的路徑(.代表所有路徑)
name:就是你給這個訪問路徑起個名字
-->
<external-path path="." name="external_storage_root" />
</paths>
