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:
Based on the DirectoryChooser from the excellent AntennaPod App by danieloeh.
As stand-alone Activity |
As DialogFragment |

For a full example see the sample app in the
repository.
Library releases are available on Maven Central, snapshots can be retrieved from Sonatype:

$ git clone https://github.com/passy/Android-DirectoryChooser.gitImport the project into your favorite IDE and add
android.library.reference.1=/path/to/Android-DirectoryChooser/library to your
project.properties.
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>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
}
}
}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);
}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:
Name of the directory to create. User can change this name when he creates the
folder. To avoid this use allowNewDirectoryNameModification argument.
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().
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.
Argument to define whether or not the directory chooser allows modification of provided new directory name.
final DirectoryChooserConfig config = DirectoryChooserConfig.builder()
.newDirectoryName("DialogSample")
.allowNewDirectoryNameModification(true)
.allowReadOnlyDirectory(true)
.initialDirectory("/sdcard")
.build();
