With Android < 10, we can list all files in a directory with this code:
File directory = new File(path);
File[] files = directory.listFiles();
But with Android 10, you receive a blank list. How to fix this problem?
Simple, you can use below code, and only add this line of code to your manifest in the application tag:
android: requestLegacyExternalStorage= "true"
Example:
<application
android:requestLegacyExternalStorage="true"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:networkSecurityConfig="@xml/network_security_config"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.tutorialspots"
android:usesCleartextTraffic="true">
