Hello,
I need my app to get all the contacts of the device and get the phone number of each one in E164 format. I assume the user could be anywhere in the world so is not "strip the first 0 and replace it with your country prefix" because I don't know for sure if each mobile number in the world starts with 0.
I've tried mixing this with this but I can't get it work it right. I'll explain:
First I've tried ContentResolver:
With this code, I get "duplicate" entries for each contact, not knowing for sure which entry corresponds to the E164 number and which one doesn't. Yes, at sight I could tell, but this is an example of what I get from one of my contacts (changing name and some numbers of course):
So I've tried a different approach: Using ContactsUtils to get each contact and, for each contact, try to get the data4. I have trouble with this, I'ts like the contact ID doesn't match the other ID:
So, I have the following code (I've switched from ContactUtils to contactresolver to make some tests). The idea is "Test" ask for all contacts and, for each one, I call a sub to get the data4 (e164 number) by the ID:
So, my problem is that most calls to GetNumeroNormalizado returns null (99%?) and, the few ones that doesn't, don't match the contact (I get a number from another person). This shouldn't be like this since the first method (the one where I get too much info) I get E164 numbers from most contacts and they correspond to the person.
I've tried replacing, in the last query, raw_contact_id for _id, but the same (or so).
I've read sometimes the data4 could be null, in that case I manually normalize it.
Also, I'd like to know how to filter the query contacts so I don't get stuff that are not numbers. I've tried filtering using ¿mimes? but I don't get the concept yet.
Thank you very much!
