不幸的是你的应用程序已停止在启动机器人

Question

我在启动应用程序时遇到此错误。这是我的代码

   package com.mycompany.myapp.android;
     import java.util.Locale;
     import android.app.Application;
     import android.content.SharedPreferences;
     import android.content.SharedPreferences.Editor;
     import android.content.res.Configuration;
     import android.preference.PreferenceManager;
     import com.droidux.components.DroidUxLib;
     import com.mycompany.myapp.R;
      public class MyApp extends Application {
/**
 * Called when the application is starting, before any activity, service, or
 * receiver objects (excluding content providers) have been created.
 */
  private Locale locale = null;
@Override
public void onCreate() {
    super.onCreate();
    // register the DroidUX library here
    DroidUxLib.register("sakldsadkdla",
            this);
    SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
    String lang = settings.getString(getString(R.string.locale_lang), "");
    changeLang(lang); 
}
public void changeLang(String lang) {
    Configuration config = getBaseContext().getResources().getConfiguration();
    if (!"".equals(lang) && !config.locale.getLanguage().equals(lang)) {
        Editor ed = PreferenceManager.getDefaultSharedPreferences(this).edit();
        ed.putString(getString(R.string.locale_lang), lang);
        ed.commit();
        locale = new Locale(lang);
        Locale.setDefault(locale);
        Configuration conf = new Configuration(config);
        conf.locale = locale;
        getBaseContext().getResources().updateConfiguration(conf, getBaseContext().getResources().getDisplayMetrics());
    }
   }    
    }

我没有日志，客户端正在报告nexus 5上的应用程序启动...他很遗憾myapp已经停止了错误。 这个错误也可能发生什么变化？
