Android DirectoryChooser

Build Status Gittip Maven Central Stories in Ready Android Arsenal

A simple directory chooser you can integrate into your Android app.

This version of the library has no additional dependencies, but requires Android v11+ to work. There is, however, a pre-v11-branch that supports down to v7 using ActionBarSherlock.

You can download the sample app from the Play Store:

Get it on Google Play

Based on the DirectoryChooser from the excellent AntennaPod App by danieloeh.

As stand-alone Activity
As DialogFragment

Usage

For a full example see the sample app in the repository.

As Library Project

Alternatively, check out this repository and add it as a library project.

$ git clone https://github.com/passy/Android-DirectoryChooser.git

Import the project into your favorite IDE and add android.library.reference.1=/path/to/Android-DirectoryChooser/library to your project.properties.

Manifest

You need to declare the DirectoryChooserActivity and request the android.permission.WRITE_EXTERNAL_STORAGE permission.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
...
<application>
    <activity android:name="net.rdrei.android.dirchooser.DirectoryChooserActivity" />
</application>

Activity

To choose a directory, start the activity from your app logic:

final Intent chooserIntent = new Intent(this, DirectoryChooserActivity.class);

final DirectoryChooserConfig config = DirectoryChooserConfig.builder()
        .newDirectoryName("DirChooserSample")
        .allowReadOnlyDirectory(true)
        .allowNewDirectoryNameModification(true)
        .build();

chooserIntent.putExtra(DirectoryChooserActivity.EXTRA_CONFIG, config);

// REQUEST_DIRECTORY is a constant integer to identify the request, e.g. 0
startActivityForResult(chooserIntent, REQUEST_DIRECTORY);

Handle the result in your onActivityResult method:

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

    if (requestCode == REQUEST_DIRECTORY) {
        if (resultCode == DirectoryChooserActivity.RESULT_CODE_DIR_SELECTED) {
            handleDirectoryChoice(data
                .getStringExtra(DirectoryChooserActivity.RESULT_SELECTED_DIR));
        } else {
            // Nothing selected
        }
    }
}

Fragment

You can also use the underlying DialogFragment for even better integration. Whether you use the Fragment as a Dialog or not is completely up to you. All you have to do is implement the OnFragmentInteractionListener interface to respond to the events that a directory is selected or the user cancels the dialog:

public class DirChooserFragmentSample extends Activity implements
    DirectoryChooserFragment.OnFragmentInteractionListener {

    private TextView mDirectoryTextView;
    private DirectoryChooserFragment mDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog);
        final DirectoryChooserConfig config = DirectoryChooserConfig.builder()
                .newDirectoryName("DialogSample")
                .build();
        mDialog = DirectoryChooserFragment.newInstance(config);

        mDirectoryTextView = (TextView) findViewById(R.id.textDirectory);

        findViewById(R.id.btnChoose)
                .setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        mDialog.show(getFragmentManager(), null);
                    }
                });
    }

    @Override
    public void onSelectDirectory(@NonNull String path) {
        mDirectoryTextView.setText(path);
        mDialog.dismiss();
    }

    @Override
    public void onCancelChooser() {
        mDialog.dismiss();
    }
}

If calling the directory chooser from your own fragment, be sure to set the target fragment first:

@Override
public void onClick(View v) {
    mDialog.setTargetFragment(this, 0);
    mDialog.show(getFragmentManager(), null);
}

Configuration

The Directory Chooser is configured through a parcelable configuration object, which is great because it means that you don't have to tear your hair out over finicky string extras. Instead, you get auto-completion and a nice immutable data structure. Here's what you can configure:

newDirectoryName : String (required)

Name of the directory to create. User can change this name when he creates the folder. To avoid this use allowNewDirectoryNameModification argument.

initialDirectory : String (default: "")

Optional argument to define the path of the directory that will be shown first. If it is not sent or if path denotes a non readable/writable directory or it is not a directory, it defaults to android.os.Environment#getExternalStorageDirectory().

allowReadOnlyDirectory : Boolean (default: false)

Argument to define whether or not the directory chooser allows read-only paths to be chosen. If it false only directories with read-write access can be chosen.

allowNewDirectoryNameModification : Boolean (default: false)

Argument to define whether or not the directory chooser allows modification of provided new directory name.

Example

final DirectoryChooserConfig config = DirectoryChooserConfig.builder()
        .newDirectoryName("DialogSample")
        .allowNewDirectoryNameModification(true)
        .allowReadOnlyDirectory(true)
        .initialDirectory("/sdcard")
        .build();
