Can I open chat with an unknown contact?

I have an unknown number I need to start chat with it.
Intent intent = new Intent();
intent
.setAction(Intent.ACTION_SEND)
.putExtra(Intent.EXTRA_TEXT, "test")
.putExtra("jid", "999999999#s.whatsapp.net")
.setType("text/plain")
.setPackage("com.whatsapp");
activity.startActivity(intent);
Whatsapp openы a window where I have to select a contact.
Is it possible to open Whatsapp and start a chat with it?

I found an answer here
String phone = "79999999999";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("whatsapp://send?phone=" + phone));
startActivity(intent);
Phone should be without any characters only digits. This number is valid 79999999999, this number is not valid +79999999999

Google Search for Android

I am trying to put a simple Google Search in my app. I found this code but it's not exactly what I am searching for. Below the search comes from a given url.
String url = "http://www.google.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
The thing is that I would like to get the search text from user and if possible without starting a new Activity like this one:
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
String term = editTextInput.getText().toString();
intent.putExtra(SearchManager.QUERY, term);
startActivity(intent);

Get the text from the user and place that in the URI, then start the intent.
String url = "http://www.google.com/search?q=" + userText;
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

Send SMS to multiple recipients via Intent

I am trying to send SMS to multiple recipients viaINTENT. I tried the following to do it:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.putExtra("sms_body", etmessage.getText().toString());
intent.setData(Uri.parse("smsto:" + returnedItems));
intent.setType("vnd.android-dir/mms-sms");
mcontext.startActivity(intent);
Where returnedItems is of Contact Numbers
But the problem is that my recipients numbers are not setting on TO section on SMS INTENT where TEXT is displayed on TEXT section.

Make sure that the numbers are seperated by ; .
Intent smsIntent = new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:1234456;234567"));
smsIntent.putExtra("sms_body", etmessage.getText().toString());
startActivity(smsIntent);
always works for me!

Did you tried below ?
Intent mIntent = new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:999999;888888"));
I also found out ";" is not working in Samsung device. You have to add "," instead of ";" for samsungs devices.
Intent mIntent = new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:999999,888888"));
Also check this answer

Intent smsIntent = new Intent(Intent.ACTION_SENDTO,Uri.parse("smsto:" + pointsList));
smsIntent.putExtra("sms_body", "Hi Friends & Families, My Location is feeling unsafe in this location");
startActivity(smsIntent);
pointsList is something like ArrayList, for example [8777675673,8566463454,7776666664].
It is working fine.

I have solved this by the following way.
Intent intent = new Intent(Intent.ACTION_SEND);
String numbers = "1234567890;9876543210;453678920"
intent.putExtra("address", numbers);
context.startActivity(Intent.createChooser(intent, context.getString(R.string.share_image)));
The numbers are separated by semi-colon (;). I read in some mobile phones the numbers need to separated by comma (,).
Hope this will help.

Android Intents.SHOW_OR_CREATE_CONTACT always show only the Uri string

I need to show/interact with a new contact before create it, and I need a simple way to add it to the phone contacts.
this is the code I use:
String contactPhone = "33333333";
Uri contactUri = Uri.parse(String.format("tel: %s", contactPhone));
Intent addContactIntent = new Intent(
ContactsContract.Intents.SHOW_OR_CREATE_CONTACT, contactUri);
addContactIntent.putExtra(ContactsContract.Intents.Insert.NAME, "FirstName" );
addContactIntent.putExtra(ContactsContract.Intents.Insert.COMPANY,"CompanyName");
addContactIntent.putExtra(ContactsContract.Intents.Insert.PHONE,contactPhone);
addContactIntent.putExtra(ContactsContract.Intents.Insert.EMAIL,"contact#email.com");
startActivity(addContactIntent);
and this is the result. The problem is that the Intent show me only the Phone instead all the info added.

ContactsContract.Intents.Insert.ACTION if you want to interact before create it:
Intent intent = new Intent(ContactsContract.Intents.Insert.ACTION,ContactsContract.Contacts.CONTENT_URI);
intent.putExtra(ContactsContract.Intents.Insert.NAME, getName());
intent.putExtra(ContactsContract.Intents.Insert.COMPANY, getCompany());
intent.putExtra(ContactsContract.Intents.Insert.EMAIL, getEmail());
intent.putExtra(ContactsContract.Intents.Insert.PHONE, getPhone());
intent.putExtra(ContactsContract.Intents.Insert.POSTAL, getAddress());
startActivity(intent);
This works pretty well. I hope this will help you.

This site (http://wiresareobsolete.com/2011/10/simplifying-interaction-with-contacts/) shows and gives examples) that SHOW_OR_CREATE_CONTACT can only trigger off "tel" or "mailto"/email for searches.

Android. Opening a contact in through intent using contact_id or contact_name

I am using ContactsContract API in Android to get the list of contacts. The is working fine.
Now I want that when I click on a name in that list an intent is generated that will open the contact in the android contact manager.
The following code crashes the app:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(ContactsContract.Contacts.CONTENT_URI + "/" + ContactsContract.Contacts._ID));
kindly help me out here with this intent

This should show the contacts 'card' in the android contact manager
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(contactID));
intent.setData(uri);
context.startActivity(intent);
