try {
    input = new FileInputStream(src1);
    SharedPreferences.Editor prefEdit =   getSharedPreferences("prueba100", MODE_PRIVATE).edit();
    prefEdit.clear();
    Map entries = XmlUtils.readMapXml(input);
    for (Map.Entry entry : entries.entrySet()) {
        putObject(prefEdit, entry.getKey(), entry.getValue());
    }
    prefEdit.apply();
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (XmlPullParserException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
