async onPressAction() {
try {
const {action, year, month, day} = await DatePickerAndroid.open({
// Use `new Date()` for current date.
// May 25 2020. Month 0 is January.
date: new Date(2018, 6, 26)
});
if (action !== DatePickerAndroid.dismissedAction) {
// Selected year, month (0-11), day
var date = new Date(year, month, day);
var year = date.getFullYear();
var month = date.getMonth()+1;
var day = date.getDate();
console.log('>>>>>>>>>>>>>'+year);
console.log('>>>>>>>>>>>>>'+month);
console.log('>>>>>>>>>>>>>'+day);
console.log(year+'-'+month+'-'+day);
