Features

Easy to Implement.
No permissions required.
Files, Directory Selection.
Single or Multiple File selection.

Installation

Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

dependencies {
        implementation 'com.github.TutorialsAndroid:FilePicker:v8.0.19'
}

Usage

If you are targeting Android 10 or higher. Set this to your manifest

<manifest ... >
  <!-- This attribute is "false" by default on apps targeting
       Android 10 or higher. -->
  <application 
       android:requestLegacyExternalStorage="true" ........ >
    ......
  </application>
</manifest>

FilePickerDialog

Start by creating an instance of DialogProperties.
```
    DialogProperties properties = new DialogProperties();
```
Now 'DialogProperties' has certain parameters.

Assign values to each Dialog Property using DialogConfig class.

    properties.selection_mode = DialogConfigs.SINGLE_MODE;
    properties.selection_type = DialogConfigs.FILE_SELECT;
    properties.root = new File(DialogConfigs.DEFAULT_DIR);
    properties.error_dir = new File(DialogConfigs.DEFAULT_DIR);
    properties.offset = new File(DialogConfigs.DEFAULT_DIR);
    properties.extensions = null;
    properties.show_hidden_files = false;

Next create an instance of FilePickerDialog, and pass Context and DialogProperties references as parameters. Optional: You can change the title of dialog. Default is current directory name. Set the positive button string. Default is Select. Set the negative button string. Defalut is Cancel.
```
    FilePickerDialog dialog = new FilePickerDialog(MainActivity.this,properties);
    dialog.setTitle("Select a File");
```

Next, Attach DialogSelectionListener to FilePickerDialog as below,

    dialog.setDialogSelectionListener(new DialogSelectionListener() {
        @Override
        public void onSelectedFilePaths(String[] files) {
            //files is the array of the paths of files selected by the Application User.
        }
    });

An array of paths is returned whenever user press the select button`.

Use dialog.show() method to show dialog.

NOTE:

Marshmallow and above requests for the permission on runtime. You should override onRequestPermissionsResult in Activity/AppCompatActivity class and show the dialog only if permissions have been granted.

        //Add this method to show Dialog when the required permission has been granted to the app.
        @Override
        public void onRequestPermissionsResult(int requestCode,@NonNull String permissions[],@NonNull int[] grantResults) {
            switch (requestCode) {
                case FilePickerDialog.EXTERNAL_READ_PERMISSION_GRANT: {
                    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                        if(dialog!=null)
                        {   //Show dialog if the read permission has been granted.
                            dialog.show();
                        }
                    }
                    else {
                        //Permission has not been granted. Notify the user.
                        Toast.makeText(MainActivity.this,"Permission is Required for getting list of files",Toast.LENGTH_SHORT).show();
                    }
                }
            }
        }

That's It. You are good to proceed further.

Important:

defaultValue, error_dir, root_dir, offset_dir must have valid directory/file paths.
defaultValue paths should end with ':'.
defaultValue can have multiple paths, there should be a ':' between two paths.
extensions must not have '.'.
extensions should end with ':' , also have ':' between two extensions. eg. /sdcard:/mnt:
