Pick contact from Contacts list and select a specific email for that contact

I know that if I create an Intent like this:
val contactPickerIntent = Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI)
startActivityForResult(contactPickerIntent, request_code)
I will be able to pick a contact from my Contacts list.
And if i set the intent like this:
val contactPickerIntent = Intent(Intent.ACTION_VIEW, ContactsContract.Contacts.CONTENT_URI)
I will be able to go into the selected contact details (from within the contacts app) but i won't be able to pick anything from it.
The thing is I need to open the contact's details and select one of it's email addresses, in case he has more than one, and pick it.
Is there a way to do that?

You can change your picker from a Contact picker to an Email picker:
Intent contacts = new Intent(Intent.ACTION_PICK, CommonDataKinds.Email.CONTENT_URI); // Note the Email!
startActivityForResult(contacts, PICK_CONTACTS);
See: https://developer.android.com/guide/components/intents-common#Contacts

Opening Native Address book in edit mode

I have a raw contact ID for a contact in my application. I want to open the native contact phonebook for editing in my contact (basically the contact in edit mode in native address book). How can I do that?

What I understand from your question is that, you have a contact id you want to open that in android native address book against that id. If that is the case then below code should help you
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf("18"));
intent.setData(uri);
startActivity(intent);
In String.valueOf() method provide the contact id you want to open.

Problem resolved.
I did this with below code
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setData(ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, contactID));
startActivity(intent);

How to find out a contact is a whatsapp user or not

I'm trying to find out whether a particular contact is a whatsapp user or not.
This goes my requirement:
I have a text to share and also have a phone number of a person as well. The priority of my sharing goes as follows
If the phone number is already present in CONTACTS and :
if the contact is a whatsapp user, I should call sharing intent of SEND with package set as "com.whatsapp"
i.e:
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.setPackage("com.whatsapp");
intent.putExtra(Intent.EXTRA_TEXT, message);
startActivity(intent);
if the contact not a whatsapp user, I should call intent for default messaging app.
i.e :
Intent intent = new Intent( Intent.ACTION_VIEW, Uri.parse( "sms:" + phoneNumber ) );
intent.putExtra( "sms_body", message );
startActivity(intent);
If the phone number is not present, create a contact and do as above.
My question now is, how do I find out whether my contact is a whatsapp user or not? Is whatsapp providing any API to find out that?
Thanks in advance
PS: I do not want to show a general sharing intent which shows a list of sharing apps. I may do that only if the device does not have whatsapp application at all.

Android Intent to pick contact from default Contact Address book

Intent pickContactIntent = new Intent(Intent.ACTION_PICK,Uri.parse("content://contacts"));
pickContactIntent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
I saw the intent above is only allowed to pick the contacts but I need to pick call logs, favorite, contact just like Android OS Contact Book , How should i achieve this ?
Is there any Intent which allows this or do we need to code it ?

Android: action_send intent is not showing facebook

I recently implemented the action-send intent to share a plain text. Facebook is installed and updated on my phone but only "Googlemail" and "Textmessage" are shown as options for sharing my text.
A short code snippet:
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, item.getTitle());
intent.putExtra(
android.content.Intent.EXTRA_TEXT,
(item.getDescription());
startActivity(Intent.createChooser(intent, "Send..."));
Any suggestions what's wrong with my app?
Normally I would think that I dont have to implement the whole facebook sdk for my simple purpose?!
Thanks in advance

The MIME type to use is text/plain, not plain/text.
