List Files Android Studio(Java)

  • 772

I'm trying to list files from directories but it seems like the directories are empty:

     File dir = Environment.getExternalStorageDirectory();
    String path = dir.getAbsolutePath();

    File carpeta = new File(path);
    String[] listado = carpeta.list();
    if (listado == null || listado.length == 0) {
        Toast.makeText(this, "No hay elementos dentro de la carpeta actual", Toast.LENGTH_SHORT).show();
        System.out.println("No hay elementos dentro de la carpeta actual");
        return;
    }
    else {
        for (int i=0; i< listado.length; i++) {
            System.out.println(listado[i]);
        }
    }

I have checked the directories and if they have files, it is internal memory and the app also has the permissions. I got it by giving Storage permissions manually, is there a way to automate it?

    Your code should work, but remember that even if you require permissions for read/write ( WRITE_EXTERNAL_STORAGE) it is very important that the permission is also defined within yourAndroidManifest.xml

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