Selecting Files and Folders in Android

The Problem

I have a program that I wanted the user to do both selecting files and selecting directories; the libraries that I found offered different UI for each action ( selecting file / folders) which is not visually suitable for the user.

The Solution

I had to write my own library to select those files and folders. This is its Git repo "MyFileChooser" where you can see the code and download the jar file.

How to use

How to set up the library in your project download the jar file

Import the jar file into your project 

1. Right click on your project.
2. Select properties
   
3. Select "Java Build Path" then "Libraries" tab and then choose "Add External JARs"
4. Choose the jar file that you downloaded.
5. Add the following lines into you manifest file

6. <activity
       android:name="com.john_aziz57.myfilechooser.MainActivity"
       android:exported="true" >
   </activity>

7. Since you will probably will read or write files don't forget to add the appropriate permissions
8. The place where you want to start the activity add the following code to select folders

    Intent i = new Intent(YourCurrentActivity,
            com.john_aziz57.myfilechooser.MainActivity.class);
    i.putExtra(MainPresenter.TAG, MainPresenter.SELECT_FOLDER);
    startActivityForResult(i, FOLDER_SELECT_CODE);

to select files

    Intent i = new Intent(YourCurrentActivity,
            com.john_aziz57.myfilechooser.MainActivity.class);
    i.putExtra(MainPresenter.TAG, MainPresenter.SELECT_FILE);
    startActivityForResult(i, FILE_SELECT_CODE);

in "onActivityResult" add the following code

protected void onActivityResult( int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
    case FILE_SELECT_CODE:
        if (resultCode == RESULT_OK) {
            // Get the Uri of the selected file
            Uri uri = data.getData();
            // Get the path
            String path = uri.getPath();
                            .......
