Android13 WRITE_EXTERNAL_STORAGE 权限失效
1. 需求及问题
- 需求是读取sdcard上txt文件
- Android13(targetSDK = 33)上取消了WRITE_EXTERNAL_STORAGE,READ_EXTERNAL_STORAGE权限。
- 取而代之的是READ_MEDIA_VIDEO,READ_MEDIA_AUDIO,READ_MEDIA_IMAGES权限
- 测验发现,即便动态申请上面三个权限,仍旧无法读取本地txt文件
2. 解决计划
- AndroidManifest.xml中添加
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:dataExtractionRules="@xml/data_extraction_rules"
android:fullBackupContent="@xml/backup_rules"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.LocationDemo"
tools:targetApi="31">
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
- Activity中新增代码
// 计划一:跳转到系统文件拜访页面,手动赋予
Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
intent.setData(Uri.parse("package:" + this.getPackageName()));
startActivity(intent);
// 计划二:跳转到系统一切需要文件拜访页面,挑选你的APP,手动赋予权限
Intent intent = new Intent(Settings.ACTION_MANAGE_ALL_FILES_ACCESS_PERMISSION);
startActivity(intent);
