Simple Android Directory picker – How?-ThrowExceptions

Exception or error:

I have just started coding in Android Studio and feeling Awesome..!!

How can I write a code for a ‘Directory Picker’. i.e., When a button is clicked, a simple Dialog/Activity screen which can show list of directories.

Also, want to store all the files in that directory in to an Array variable. (Once OK button is clicked).

PS: I have searched here and found some cool ‘File choose’ but m looking for Directory Chooser..!

Thanks in advance.

How to solve:


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

And get result Uri from onActivityResult data.getData()

    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());



Also you can use some libraries.
for example:


There’s an open source library that does directory chooser and open/save file activities as well. It can be found on GitHub at

Works on Android API Level 17 and above

Disclaimer: I wrote it


As of Android 10 (API 29), direct access to external storage is deprecated in favor of storage access framework


Use below code to select directory

        Intent result = new Intent();
        result.putExtra("chosenDir", path);
        setResult(RESULT_OK, result);

And to get the selected path override onActivityResult :

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == PICK_DIRECTORY && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        String path = (String) extras.get("chosenDir");
