    super.onCreate(savedInstanceState);

    // Create a simple button to start the file chooser process
    Button button = new Button(this);
    button.setText(R.string.choose_file);
    button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // Display the file chooser dialog
            showChooser();
        }
    });


    setContentView(button);
}




private void showChooser() {
    // Use the GET_CONTENT intent from the utility class
    Intent target = FileUtils.createGetContentIntent();
    // Create the chooser Intent
    Intent intent = Intent.createChooser(
            target, getString(R.string.chooser_title));
    try {
        startActivityForResult(intent, REQUEST_CODE);
    } catch (ActivityNotFoundException e) {
        // The reason for the existence of aFileChooser
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        case REQUEST_CODE:
            // If the file selection was successful
            if (resultCode == RESULT_OK) {
                if (data != null) {
                    // Get the URI of the selected file
                    final Uri uri = data.getData();
                    Log.i(TAG, "Uri = " + uri.toString());
                    try {
                        // Get the file path from the URI
                        final String path = FileUtils.getPath(this, uri);
                        Toast.makeText(FileChooserExampleActivity.this,
