如何使用Storage access Framework访问"/storage/emulated/0/Android/media/“？

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;

private static final int REQUEST_CODE = 1;

private void startStorageAccessFramework() {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
    startActivityForResult(intent, REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
        Uri uri = data.getData();
        // 在这里进行操作，比如创建文件、读写文件等
    }
}

startStorageAccessFramework();
