Iam making an android application similar to skype what i want to know is how to synchronize android contacts with my application so that the numbers which are registered with my application and are also in my android contacts got a symbol. For example in your contact list you see a skype icon or whatsapp icon with those contacts who are registered with skype or whats app.Anyone can guide me what to do.thanks!
If you're using an Android-based device, you can just tap and hold on a contact to enter selection mode. From there, you can select as many contacts as you want, then press the Delete button to remove them all at once.
Please refer to the android.provider.ContactsContract class
. Since it is very broad, I recommend you to first take a look at the SDK description of ContactsContract.RawContact. There you will find description with code snippets for basic operation on Contacts.
Also, take a look at the Android SDK code examples:
Android Sample - ContactOperations
