Hi there is a way to select folder where user want to save file in android . I check out http://code.google.com/p/android-file-dialog/ it has functionality to select file but i wa

Solution 1:

How about using OI File Manager? This App has the following Intents: PICK_FILE, PICK_DIRECTORY. There is even sample code on the page for using the Intents.

Solution 2:

I used the same source in my app (pretty sure), and there is a block of code:

protectedvoidonListItemClick(ListView l, View v, int position, long id) {
    if (file.isDirectory()) {
        selectButton.setEnabled(false);
        if (file.canRead()) {
            lastPositions.put(currentPath, position);
            getDir(path.get(position));
        } else {
            new AlertDialog.Builder(this)
                    .setIcon(R.drawable.icon)
                    .setTitle(
                            "[" + file.getName() + "] "
                                    + getText(R.string.cant_read_folder))
                    .setPositiveButton("OK",
                            new DialogInterface.OnClickListener() {

                                @Override
                                publicvoidonClick(DialogInterface dialog,
                                        int which) {

                                }
                            }).show();
        }
    } else {
        selectedFile = file;
        v.setSelected(true);
        selectButton.setEnabled(true);
    }
}

You just have to edit how it handle's if (file.isDirectory()). I would recommend declaring a boolean value in your Activity which you change to true if the file is a directory and it is already false. Then if said value is true, then traverse the directory. Also when you change said value to true, you would need to call selectButton.setEnabled(true). This would be quite a bit less complicated than making your own code, I would say.

Solution 4:

I encountered the same issue and I end up using NoNonsense-FilePicker

Add to gradle file

compile 'com.nononsenseapps:filepicker:4.0.0'

Trigger file/folder/dir pick

try {

                    Utils.makeHepticFeedback(getActivity());

                    Intent selectDirectoyIntent = new Intent(getActivity(), FilePickerActivity.class);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_ALLOW_MULTIPLE, false);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_ALLOW_CREATE_DIR, true);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_MODE, FilePickerActivity.MODE_DIR);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_START_PATH, Environment.getExternalStorageDirectory().getPath());
                    startActivityForResult(selectDirectoyIntent, FILE_CODE);

                } catch (Exception e) {
                    Log.e(LOG_TAG, "exception", e);
                    e.printStackTrace();

                    Toast.makeText(getActivity(), e.toString(), Toast.LENGTH_SHORT).show();
                }   

Handle Activity result to get selected file or files

@OverridepublicvoidonActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);

            if (resultCode == Activity.RESULT_OK && requestCode == CHOOSE_IMAGE_REQUEST_CODE) {
                UriselectedImageUri= data.getData();
                StringselectedImagePath= getRealPathFromURI(selectedImageUri);


                // NOW WE HAVE OUR WANTED STRINGif (selectedImagePath != null) {
                    System.out
                            .println("selectedImagePath is the right one for you!");

                    PreferenceHelper.getPreferenceHelperInstance().setString(getActivity(),
                            PreferenceHelper.PLAYER_BACKGROUND,
                            selectedImageUri.toString());

                    Glide.with(getActivity()).load(Uri.parse(
                            PreferenceHelper.getPreferenceHelperInstance().getString(getActivity(),
                                    PreferenceHelper.PLAYER_BACKGROUND
                                    , AppConstants.DEFAULT_BACKGROUND_URL))).
                            into((ImageView) ButterKnife.findById(getActivity(), R.id.play_back));

                }
            } elseif (requestCode == FILE_CODE && resultCode == Activity.RESULT_OK) {

                if (null != data && !data.getBooleanExtra(FilePickerActivity.EXTRA_ALLOW_MULTIPLE, false)) {
                    // The URI will now be something like content://PACKAGE-NAME/root/path/to/fileUriuri= data.getData();
                    // A utility method is provided to transform the URI to a File objectFilefile= com.nononsenseapps.filepicker.Utils.getFileForUri(uri);
                    // If you want a URI which matches the old return value, you can doUrifileUri= Uri.fromFile(file);
                    // Do something with the result...

                    Snackbar.make(fileFormat, "Recording folder updated to" + fileUri.getPath() + " ¯\\_(ツ)_/¯ ", Snackbar.LENGTH_SHORT).show();

                    AppConfig.RECORDING_FOLDER = fileUri.getPath();

                    PreferenceHelper.getPreferenceHelperInstance().setString(getActivity(), PreferenceHelper.RECORDING_FOLDER, AppConfig.RECORDING_FOLDER);

                    setUpSettingValue();

                } else {

                    // Handling multiple results is one extra step
                    ArrayList<String> paths = data.getStringArrayListExtra(FilePickerActivity.EXTRA_PATHS);
                    if (paths != null) {
                        for (String path : paths) {
                            Uriuri= Uri.parse(path);
                            // Do something with the URIFilefile= com.nononsenseapps.filepicker.Utils.getFileForUri(uri);
                            // If you want a URI which matches the old return value, you can doUrifileUri= Uri.fromFile(file);
                            // Do something with the result...

                            Toast.makeText(getActivity(), "Selected dir" + fileUri.getPath(), Toast.LENGTH_SHORT).show();


                        }
                    }
                }
            }

        }
