If we pass null to Ints.tryParse it throws NullPointerException.
Method uses AndroidInteger.tryParse(), but the first line there is checkNotNull() method.

implements Serializable {
    static final IntConverter INSTANCE = new IntConverter();
    @Override
    protected Integer doForward(String value) {
      return Integer.decode(value);
    }
    @Override
    protected String doBackward(Integer value) {
      return value.toString();
    }
    @Override
    public String toString() {
      return "Ints.stringConverter()";
    }
    private Object readResolve() {
      return INSTANCE;
    }
    private static final long serialVersionUID = 1;
  }
  /**
