Create a new contact android program, call the android system to create a new contact, but cannot directly insert the phone number into it...

var mainActivity = plus.android.runtimeMainActivity();

var Uri = plus.android.importClass("android.net.Uri");

var Intnet = plus.android.importClass("android.content.Intent");

var uri = Uri.withAppendedPath(Uri.parse("content://com.android.contacts"), "contacts")

var call = new Intnet("android.intent.action.INSERT", uri);

call.putExtra("android.provider.ContactsContract.Intents.Insert.phone", "18780108962");

mainActivity.startActivity(call);

call.putExtra("android.provider.ContactsContract.Intents.Insert.phone", "18780108962"); This sentence doesn't work, I don't know why?
