title: How can I save my Language?
body: <p>I have a Spinner and when I click, for example, to German the App is translated to German. When I restart the App I have the default Language again.
  My question now is how to save the Language that when I restart the app is still changed in the selected Language?</p>
  
  <p>The code of my Activity is:</p>
  
  <pre><code>private Typeface ttf;
  
  Spinner spinnerctrl;
  Button btn;
  Locale myLocale;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.dialog_einstellungen);
      //Schrift &amp; OnClickListener
      ttf = Typeface.createFromAsset(getAssets(), "schrift.ttf");
      ((TextView)findViewById(R.id.settings_title)).setTypeface(ttf);
      ((TextView)findViewById(R.id.appinfo)).setTypeface(ttf);
      findViewById(R.id.appinfo).setOnClickListener(this);
      ((TextView)findViewById(R.id.settings_back)).setTypeface(ttf);
      findViewById(R.id.settings_back).setOnClickListener(this);
      //Spinner Language
      spinnerctrl = (Spinner) findViewById(R.id.spinner);
      spinnerctrl.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
          public void onItemSelected(AdapterView&lt;?&gt; parent, View view, int pos, long id) {
              if (pos == 1) {
                  setLocale("ar");
              } else if (pos == 2) {
                  setLocale("en");
              } else if (pos == 3) {
                  setLocale("de");
              } else if (pos == 3) {
                  setLocale("nv-rUs");
              }
          }
          public void onNothingSelected(AdapterView&lt;?&gt; arg0) {
              // TODO Auto-generated method stub
          }
      });
  }
  //TODO Language translation System
  //LanguageTranslation
  public void setLocale(String lang) {
      myLocale = new Locale(lang);
      Resources res = getResources();
      DisplayMetrics dm = res.getDisplayMetrics();
      Configuration conf = res.getConfiguration();
      conf.locale = myLocale;
      res.updateConfiguration(conf, dm);
      Intent refresh = new Intent(this, Settings.class);
      startActivity(refresh);
      finish();
  }
  
  @Override
  public void onBackPressed() {
  }
  
  @Override
  public void onClick(View view) {
      if(view.getId()==R.id.appinfo) {
         showAppinfo();
      } else if(view.getId()==R.id.settings_back) {
          finish();
      }
  }
  
  private void showAppinfo() {
      final Dialog dialog = new Dialog(this,android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
      dialog.setContentView(R.layout.dialog_appinfo);
      ((TextView)(dialog.findViewById(R.id.appinfo_herrausgeber))).setTypeface(ttf);

              dialog.dismiss();
              return;
          }
      });
      dialog.show();
