Storage Chooser 2.0 ! - Changes and Snippets

A pretty and simple directory chooser and file picker library for 4.4+ devices. This library was created to be included in OpenGApps App. There are too many storage chooser out there but this one is too materially 😛 . Easy to implement and does not take a lot of your valueable time in setting-up all the other necessary things that every developer seeks, like

saving path to sharedPreference
event when path is selected and act upon that path
and much more.

There are also some really nice features that I thought would come in handy:

You show a quick overview of the storages present and their memory available before choosing so that users know which storage to choose.
you can choose between sheet and sleek layouts.
Inline create folder view (not another dialog to handle)
Full localization. I mean literally every strings can be localized to your desired language.
Memory thresholding - a restriction or a toast that it shows when user's memory is less than your defined memory for operations.
and more will be added soon.

Preview

Installation

Add this to your root build.gradle file under repositories:

allprojects {
	repositories {
		maven { url "https://jitpack.io" }
	}
}

Add this to your app level build.gradle as dependency:

com.github.codekidX:storage-chooser:2.0.3

Notes

Before you implement this library here are some notes that you can follow to avoid errors.

Confirm:

You have asked for Runtime Permission from the user in the past to avoid read errors.

Permissions with "READ_EXTERNAL_STORAGE" and "WRITE_EXTERNAL_STORAGE" is enough for this library to work.

This library follows same color scheme as that of the parent app to maintain the aesthetic of the parent app. See the color scheme section below

Simple Type

Let's you toggle between inernal/external root directory.

// ~

// Initialize Builder
StorageChooser chooser = new StorageChooser.Builder()
.withActivity(MainActivity.this)
.withFragmentManager(getFragmentManager())
.withMemoryBar(true)
.build();

// Show dialog whenever you want by
chooser.show();

// get path that the user has chosen
chooser.setOnSelectListener(new StorageChooser.OnSelectListener() {
    @Override
    public void onSelect(String path) {
        Log.e("SELECTED_PATH", path);
    }
});

OUTPUT: /storage/emulated/0

Pre-defined Type

Let's you append a specific path to the root of internal or external directory.

// --- ADD --
.withPredefinedPath(STATIC_PATH)

OUTPUT: /storage/emulated/0/Downloads/CodekidLabs

Custom Type

Let's your user choose custom directory/file.

Directory Chooser

// --- ADD ---
.allowCustomPath(true)
.setType(StorageChooser.DIRECTORY_CHOOSER)

File Picker

// --- ADD ---
.allowCustomPath(true)
.setType(StorageChooser.FILE_PICKER)

Save directly to preference

// --- ADD ---
.actionSave(true)
.withPreference(sharedPreferences)

Get path from preference

String path = sharedPreferences.getString(DiskUtil.SC_PREFERENCE_KEY,"");

(2.0) Theme

A guide on how to set a theme is posted here

(2.0) File Filter

File filters are good and when your app is made for a specific purpose like choosing songs to be added in a playlist you might not want the user to go into the folders where there are no songs. Now you can add filter to builder instance like this builder.filter(StorageChooser.FileType.AUDIO); this will filter out all folders containing audio files for you and thereby reducing some effort from user side.

In version 2.0.3+, there is a support for custom file filters, all you need to do is create an ArrayList<String> of all the extensions without the . before it and send it to builder.customFilter function.

filter	extensions
StorageChooser.FileType.AUDIO	.mp3 .ogg
StorageChooser.FileType.VIDEO	.mp4 .ts .mkv .avi .flv
StorageChooser.FileType.IMAGES	.jpg .jpeg .png .gif .tiff
StorageChooser.FileType.DOCS	.pdf .doc .docx .ppt .xls

(2.0) Multiselect

It's already in there you don't need to write any special code for it. Just make sure your type of chooser is of type FILE_PICKER. builder.setType(StorageChooser.FILE_PICKER);

Localization

A seperate localization wiki is posted here
