Question

I am doing an application where I need to store some numbers and when someone call on phone I need to check if incoming number is present in my database or not.

What I did

I stored phone numbers in shared preferences. Internally android uses Map for this purpose.

Problem:

Lets say I stored 9089889899 (10 digit phone number). Now if I get an incoming call from this number it may BroadcastReceiver having 09089889899 or [phone] number for the same.

So my problem is that if I stored a number into preferences then how can I match the incoming number is present in preferences or not.

Answer 1

I suggest that you use something like libphonenumber to handle the phone numbers independent of the format.

There is also some functions for formatting and comparing numbers in PhoneNumberUtils.
