Use this code,
SharedPreferences preferences=this.getSharedPreferences("com.example.application", Context.MODE_PRIVATE);
Map<String,?> keys = preferences.getAll();
Properties properties = new Properties();
for(Map.Entry<String,?> entry : keys.entrySet()){
String key = entry.getKey();
String value = entry.getValue().toString();
properties.setProperty(key, value);
}
try {
File file = new File("externalPreferences.xml");
FileOutputStream fileOut = new FileOutputStream(file);
properties.storeToXML(fileOut, "External Preferences");
fileOut.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
and to retrive use this,
try {
File file = new File("externalPreferences.xml");
FileInputStream fileInput = new FileInputStream(file);
Properties properties = new Properties();
properties.loadFromXML(fileInput);
fileInput.close();
Enumeration enuKeys = properties.keys();
SharedPreferences.Editor editor = preferences.edit();
while (enuKeys.hasMoreElements()) {
String key = (String) enuKeys.nextElement();
String value = properties.getProperty(key);
editor.putString(key, value);
editor.commit();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
NOTE You can handle only String type preferences with this code,
