Buggy source:
@Override protected void onCreate(Bundle savedInstanceState){
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  ButterKnife.bind(this);
  cityCountryName=sharedPreferences.getString(CITY_COUNTRY_NAME,"String_Node_Str");
  actvCityCountryName.setText(cityCountryName);
  mFetchThreadData=new FetchThreadData<>(mHandler);
  mFetchThreadData.start();
  mFetchThreadData.getLooper();
  initServerResponse();
  if (!cityCountryName.equals("String_Node_Str")) {
    mFetchThreadData.queueResponce(0,cityCountryName);
  }
  if (database.isOpen()) {
    checkDatabaseState();
  }
 else {
    database=databaseHelper.getReadableDatabase();
    checkDatabaseState();
  }
  mAdapter=new SimpleCursorAdapter(this,R.layout.dropdown_text,null,new String[]{CITY_COUNTRY_NAME},new int[]{R.id.text},0);
  mAdapter.setFilterQueryProvider(new FilterQueryProvider(){
    @Override public Cursor runQuery(    CharSequence constraint){
      if (constraint != null) {
        if (constraint.length() >= 3 && !TextUtils.isEmpty(constraint)) {
          Bundle bundle=new Bundle();
          String query=charArrayUpperCaser(constraint);
          bundle.putString(CITY_ARGS,query);
          getLoaderManager().restartLoader(0,bundle,MainActivity.this).forceLoad();
        }
      }
      return null;
    }
  }
);
  actvCityCountryName.setOnItemClickListener(new AdapterView.OnItemClickListener(){
    public void onItemClick(    AdapterView<?> listView,    View view,    int position,    long id){
      Cursor cursor=(Cursor)listView.getItemAtPosition(position);
      cityCountryName=cursor.getString(cursor.getColumnIndexOrThrow(CITY_COUNTRY_NAME));

Fixed version (ground truth):
@Override protected void onCreate(Bundle savedInstanceState){
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  ButterKnife.bind(this);
  cityCountryName=sharedPreferences.getString(CITY_COUNTRY_NAME,"String_Node_Str");
  actvCityCountryName.setText(cityCountryName);
  mFetchThreadData=new FetchThreadData<>(mHandler);
  mFetchThreadData.start();
  mFetchThreadData.getLooper();
  initServerResponse();
  if (database.isOpen()) {
    checkDatabaseState();
  }
 else {
    database=databaseHelper.getReadableDatabase();
    checkDatabaseState();
  }
  mAdapter=new SimpleCursorAdapter(this,R.layout.dropdown_text,null,new String[]{CITY_COUNTRY_NAME},new int[]{R.id.text},0);
  mAdapter.setFilterQueryProvider(new FilterQueryProvider(){
    @Override public Cursor runQuery(    CharSequence constraint){
      if (constraint != null) {
        if (constraint.length() >= 3 && !TextUtils.isEmpty(constraint)) {
          Bundle bundle=new Bundle();
          String query=charArrayUpperCaser(constraint);
          bundle.putString(CITY_ARGS,query);
          getLoaderManager().restartLoader(0,bundle,MainActivity.this).forceLoad();
        }
      }
      return null;
    }
  }
);
  actvCityCountryName.setOnItemClickListener(new AdapterView.OnItemClickListener(){
    public void onItemClick(    AdapterView<?> listView,    View view,    int position,    long id){
      Cursor cursor=(Cursor)listView.getItemAtPosition(position);
      cityCountryName=cursor.getString(cursor.getColumnIndexOrThrow(CITY_COUNTRY_NAME));
      actvCityCountryName.setText(cityCountryName);
