如何重現：給SD卡上的資源添加標簽

看起來這個錯誤不會影響 Android 11

使用權限 android:name="android.permission.READ_EXTERNAL_STORAGE" 使用權限 android:name="android.permission.WRITE_EXTERNAL_STORAGE"

    android:name="space.taran.arknavigator.ui.App"
    android:allowBackup="true"
    android:hardwareAccelerated="false"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:requestLegacyExternalStorage="true"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:usesCleartextTraffic="true"

Answer 1

<manifest ....>   

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<application ....>

 ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE},1);
