I'm using SharedPreferences in my project with MODE_PRIVATE, when i cleared the app from recent activity list, and opens the app again, all my preference data is cleared.
I'm using this class fro setting and getting preference.
public class Preferences {
private Context _context;
private SharedPreferences _preferences;
private Editor _editor;
private String prefName = "pref";
//=====
public Preferences(Context context){
_context = context;
_preferences = this._context.getSharedPreferences(prefName, Context.MODE_PRIVATE);
_editor = this._preferences.edit();
}
//=====
public Preferences commit(){
_editor.commit();
return this;
}
//=====
public Preferences set(String key, String value){
_editor.putString(key, value);
return this;
}
//=====
public String get(String key){
return _preferences.getString(key, "");
}
//=====
public Preferences set(String key, int value){
_editor.putInt(key, value);
return this;
}
//=====
public int getInt(String key){
return _preferences.getInt(key, 0);
}
//=====
public Preferences setBoolean(String key, boolean value){
_editor.putBoolean(key, value);
return this;
}
//=====
public void removeKey(String key){
_editor.remove(key);
}
//=====
public boolean getBoolean(String key){
return _preferences.getBoolean(key, false);
}
}
can any one help me ...??
change your set method like this
public Preferences set(String key, int value){
_editor.putInt(key, value);
_editor.commit();
return this;
}
you don't need separate commit() into independent method.
good luck
this is another example, in this example i create a value that save my city name and when my app lunched i check for existing , if exist the value of that key returned to me.
SharedPreferences sp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// define sp
sp=getSharedPreferences("test", Context.MODE_PRIVATE);
// get sp value if exist
if(sp.contains("EkbatanApp")){
String spResult=sp.getString("EkbatanApp", "");
}
}
//save key
public void SaveSettingOnClick(View v){
Editor editor=sp.edit();
editor.putString("EkbatanApp", "Borujerd");
editor.commit();
}
