Answer 1

Try to use Intent.ACTION_OPEN_DOCUMENT_TREE

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){ 
    Intent i = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE); 
    i.addCategory(Intent.CATEGORY_DEFAULT);
    startActivityForResult(Intent.createChooser(i, "Choose directory"), 9999);
}

And get the result Uri from onActivityResult data.getData()

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch(requestCode) {
        case 9999:
            Log.i("Test", "Result URI " + data.getData());
            break;
    }
}
