Setup

The simplest way to use this library is to add the library as dependency to your build.

Gradle

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        maven { url "https://maven.google.com" }
                google()
                jcenter()
                maven { url 'https://jitpack.io' }
        ...
    }
}

Step 2. Add the dependency

// builde.gradle(app level)
android{
    ...
    compileOptions {
                sourceCompatibility JavaVersion.VERSION_1_8
                targetCompatibility JavaVersion.VERSION_1_8
        }
        dataBinding {
                enabled = true
        }
}

dependencies {
    implementation 'com.github.salehyarahmadi:FileAndFolderPicker:1.0.4'
}

Usage

Java

For select single file

if(permissionGranted()) {
    SingleFilePickerDialog singleFilePickerDialog = new SingleFilePickerDialog(this,
            () -> Toast.makeText(MainActivity.this, "Canceled!!", Toast.LENGTH_SHORT).show(),
            files -> Toast.makeText(MainActivity.this, files[0].getPath(), Toast.LENGTH_SHORT).show());
    singleFilePickerDialog.show();
}
else{
    requestPermission();
}

For select multiple files

if(permissionGranted()) {
    MultiFilePickerDialog multiFilePickerDialog = new MultiFilePickerDialog(this,
            () -> Toast.makeText(MainActivity.this, "Canceled!!", Toast.LENGTH_SHORT).show(),
            files -> Toast.makeText(MainActivity.this, files[0].getPath(), Toast.LENGTH_SHORT).show()
    );
    multiFilePickerDialog.show();
}
else{
    requestPermission();
}

For select directory

if(permissionGranted()) {
    DirectoryPickerDialog directoryPickerDialog = new DirectoryPickerDialog(this,
            () -> Toast.makeText(MainActivity.this, "Canceled!!", Toast.LENGTH_SHORT).show(),
            files -> Toast.makeText(MainActivity.this, files[0].getPath(), Toast.LENGTH_SHORT).show()
    );
    directoryPickerDialog.show();
}
else{
    requestPermission();
}

Permissions

private boolean permissionGranted(){
    return ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED
            && ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED;
}
private void requestPermission(){
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
}

In all types, you receive an array of files. In case of single file and directory picker, you have to use index 0 of files array. But in multiple files picker you can use all indices of array.
