How to remove a contact programmatically in android
<p>I try the following code to remove contact with a specified number:</p>

<pre><code>private void removeContact(Context context, String phone) {
    //context.getContentResolver().delete(Contacts.Phones.CONTENT_URI, phone, null);
    context.getContentResolver().delete(Contacts.Phones.CONTENT_URI,
          Contacts.PhonesColumns.NUMBER+"=?", new String[] {phone});
}
</code></pre>

<p>But I get this exception:</p>

<pre><code>java.lang.UnsupportedOperationException: Cannot delete that URL: content://contacts/phones
    at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:130)
    at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:110)
    at android.content.ContentProviderProxy.delete(ContentProviderNative.java:362)
    at android.content.ContentResolver.delete(ContentResolver.java:386)
</code></pre>

<p>Can you please tell me how to fix my problem?</p>

<p>Thank you.</p>
