How to display a contact in Android

//Look up a contact by phone number and display it.

Intent intent = new Intent(ContactsContract.Intents.SHOW_OR_CREATE_CONTACT);
intent.setData(Uri.fromParts("tel", vc.cellphone, null));
startActivity(intent);

This code works as intended. However, if there is more than one contact with that number, we get a crash. When the crash happens. Logcat says:

After the question updates, most of this answer became irrelevant, but the links may still be useful for others having issues with the contacts, so instead of deleting the answer, I decided to keep those:

Links to Q&A in SO:

How can I launch the 'Add Contact' activity in android

How to call Android contacts list?

Launching external application from my app

This one deals with exactly your problem: Android - Show list of contacts with same phone number . There is an answer there by DEzra suggesting to use "Android content provider api in combination with a SQL query"
