how to remove duplicate contacts from arraylist

Question

I have created an app in which I am getting the contacts from a device. But I want to remove the duplicate contacts from the results.

How could I do it?

Answer 1

Add the following checking in the place of list.add(new ProfileBean(name, phoneNumber)); before adding into list:

int flag = 0
if(list.size() == 0){
list.add(new ProfileBean(name, phoneNumber));
}
    for(int i=0;i

}

    }
if(flag == 1){
list.add(new ProfileBean(name, phoneNumber));
}
