force close while converting charsequence to string

Whenever i converts charsequence to string my application shows force quit message. This is the code

public void onTextChanged (CharSequence s, int start, int before, int count) {
    String query =  td.searchRecord(s.toString());
    Toast.makeText(getApplicationContext(),query, Toast.LENGTH_SHORT).show();
}

This is the logcat.
