Download

Gradle:

repositories {
    maven { url ‘https://jitpack.io’ }
}

dependencies {
    implementation 'com.github.abhishekti7:UnicornFilePicker:$latest_version'
}

How do I use Unicorn File Picker?

Permission

The library requires two permissions:

• android.permission.READ_EXTERNAL_STORAGE
• android.permission.WRITE_EXTERNAL_STORAGE

If you are targeting Android 6.0+, you need to handle runtime permission request before next step.

Also, don't forget to add requestlegacyexternalstorage=true for Android 10.

Simple usage snippet

Start UnicornFilePicker from current Activity or Fragment:

UnicornFilePicker.from(MainActivity.this)
                    .addConfigBuilder()
                    .selectMultipleFiles(false)
                    .showOnlyDirectory(true)
                    .setRootDirectory(Environment.getExternalStorageDirectory().getAbsolutePath())
                    .showHiddenFiles(false)
                    .setFilters(new String[]{"pdf", "png", "jpg", "jpeg"})
                    .addItemDivider(true)
                    .theme(R.style.UnicornFilePicker_Dracula)
                    .build()
                    .forResult(Constants.REQ_UNICORN_FILE);

Themes

There are two built-in themes you can use to start UnicornFilePicker:

• R.style.UnicornFilePicker_Default (light mode)
• R.style.UnicornFilePicker_Dracula (dark mode)

You can also define your own custom theme.

Receive Result

In onActivityResult() callback of the starting Activity or Fragment:

List<String> mSelected_files;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_CHOOSE && resultCode == RESULT_OK) {
        ArrayList<String> files = data.getStringArrayListExtra("filePaths");
        for(String file : files){
            Log.e(TAG, file);
        }
    }
}
