You can `getIntent` anywhere in the Activity. Why do you need the data before an Activity starts? — OneCricketeer, Aug 23 '16 at 14:06

I want to get the data in Activity B anytime.So what should I do?

Can you please tell,how you can get data in activity B anytime?

Here,you can store your data in constant or share preferences and get at activity B whenever you require.

OR

If you want to get data from service then you can use broadcast receiver so you can receive data at activity B.

@JACKGAO in that case you should be using a service with a broadcast receiver and Activity B should be listening for that specific broadcast from your service to update it – tyczj Aug 23 '16 at 14:15
