int MyReqCode = 122333;

//...

Intent intent = new Intent().setType("*/*")
    .setAction(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);

startActivityForResult(Intent.createChooser(intent, "Select a file"), MyReqCode);

 

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == MyReqCode && resultCode == RESULT_OK) {
        Uri selfile = data.getData();

        Toast.makeText(getApplicationContext(),
                getFilenameFromUri(selfile), Toast.LENGTH_LONG).show();
    }
}

private String getFilenameFromUri(Uri uri) {

    String fn = "";

    //선택된 경로 정보:  uri.getPath()

    if(uri.getScheme().equals("contents")) {
        Cursor cursor = getContentResolver().query(uri, null, null, null, null);
        try {
            if (cursor != null && cursor.moveToFirst()) {
                fn = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
            }
        } finally {
            cursor.close();
        }
    }
    if (fn == null) {
        fn = uri.getPath();
        int cut = fn.lastIndexOf('/');
        if (cut != -1) {
            fn = fn.substring(cut + 1);
        }
    }
    return fn;
