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 FloatConverter INSTANCE = new FloatConverter();
    @Override
    protected Float doForward(String value) {

    }
    @Override
    protected String doBackward(Float value) {
      return value.toString();
    }
    @Override
    public String toString() {
      return "Floats.stringConverter()";
    }
    private Object readResolve() {
      return INSTANCE;
    }
