to make user to select the multi contacts from phone-book and send sms

I am working on my app in which user will select and saves the contacts (3 contacts) from phonebook and sends them SMS with a click of a button . I am done with searching on that sms and button part, all i want to know what things will it require for taking the contacts input and saving them. I'm not expecting any full fledged programming from someone just the breif details on which i can search upon. I am only some months old for android. Thanks in advance

try this, use-
Intent intent = new Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);
then, in your onAcitivityResult:
Uri contact = data.getData();
ContentResolver cr = getContentResolver();
Cursor c = managedQuery(contact, null, null, null, null);
// c.moveToFirst();
while(c.moveToNext()){
String id = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(Phone.CONTENT_URI,null,Phone.CONTACT_ID +" = ?", new String[]{id}, null);
while(pCur.moveToNext()){
String phone = pCur.getString(pCur.getColumnIndex(Phone.NUMBER));
textview.setText(name+" Added " + phone);
}
}
}

Views contact details and get phone number selected by user

I want to display the native android contacts list and then once the user picks a contact, i would like to move to the next native screen where it shows the details of the contact (like phone numbers, email, etc).
Now once the user selects either an email address or a phone number, I would then like to get that data back to my original activity and do further processing.
I know that I could use
startActivityForResult(new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI), REQUEST_CODE_PICK_CONTACT);
and then myself parse the contact using getContentResolver().query() and then store each of the required fields. Then finally display on a separate activity as contact details and then once the user chooses any one of the phone numbers or emails, then i use that to do further processing.
I tried to do the following inside onActivityResult():
Uri contactData = data.getData();
Intent intent = new Intent(Intent.ACTION_PICK, contactData);
startActivityForResult(intent, REQUEST_CODE_PICK_CONTACT_DETAIL);
This displays the details of the contact but when the user selects a particular number, android calls it instead of passing it back to me in the previous activity.
But I would like to use the native screens if possible and it would require a lot less parsing and no extra activities/fragments.
Could someone suggest how to go about doing this?
Thanks

You can get contact details from phone contact doing this way
Uri uri = data.getData();
String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER};
Cursor people = getActivity().getContentResolver().query(uri, projection, null, null, null);
int indexName = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexNumber = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
int type = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
people.moveToFirst();
do {
String name = people.getString(indexName);
String number = people.getString(indexNumber);
System.out.println(name+number);
} while (people.moveToNext());

This might help:
Uri contactData = data.getData();
ContentResolver cr = getContentResolver();
Cursor c = cr.query(contactData, null, null, null, null);
if (c.moveToFirst()) {
String id = c
.getString(c
.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String hasPhone = c
.getString(c
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (hasPhone.equalsIgnoreCase("1")) {
Cursor phones = getContentResolver()
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = " + id, null, null);
phones.moveToFirst();
String cNumber = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Toast.makeText(getApplicationContext(), cNumber,
Toast.LENGTH_SHORT).show();
String nameContact = c
.getString(c
.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
// contact number = cNumber
//contact name = nameContact
}
}

Effective way to get contacts info with photo

I want to get some basic info of all contacts(I use api lvl 8). Currently i use this code snippet
private List<ContactInfo> readContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, Phone.DISPLAY_NAME + " ASC");
for (int i = 0; i < cur.getColumnCount(); i++) {
Log.v("COlum", cur.getColumnName(i));
}
List<ContactInfo> temp = new ArrayList<ContactInfo>();
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
ContactInfo mContactInfo = new ContactInfo();
String id = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
mContactInfo.setId(Long.parseLong(id));
String name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer
.parseInt(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
mContactInfo.setmDisplayName(name);
// get the <span class="IL_AD" id="IL_AD7">phone
// number</span>
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
while (pCur.moveToNext()) {
String phone = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
mContactInfo.setmPhoneNumber(phone);
}
pCur.close();
// get email and type
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = ?", new String[] { id }, null);
while (emailCur.moveToNext()) {
// This would allow you get several email <span
// class="IL_AD" id="IL_AD9">addresses</span>
// if the email addresses were stored in an array
String email = emailCur
.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
mContactInfo.setmEmail(email);
}
emailCur.close();
temp.add(mContactInfo);
}
}
}
return temp;
}
and pass to custom adapter (extended baseadapter). I get contact's photo using:
public static Bitmap loadContactPhoto(ContentResolver cr, long id) {
Uri uri = ContentUris.withAppendedId(
ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = openContactPhotoInputStream1(cr, uri);
if (input == null) {
return null;
}
return BitmapFactory.decodeStream(input);
}
I tested on my phone with 2x contacts (had photo). I took ~ 10s to fetch all contact at 1st runtime. I try force close in application settings and run again. This time it took ~2s to get data.So i want to know the most effective way to get contacts info.
I found some similar SO questions but they dont need photo. contacts in android
I tried use cursor and cursor adapter but i dont know what query to get photo_uri + contact name at the same time.
Edit: i removed all getColumnIndex i can out of loop and project only column i want. The performance is better(10s => 5s).
What i want to know :
Better way to query info and set to my ContactInfo model or the query which get name, phone number, email, photo at the same time to pass to cursor adapter.
Thanks in advance

I changed to CusorAdapter and use ContactsPhotoLoader from Contacts app and performance is improved.

To get contact info you have to work with the Android Contact API. Also you have to keep in min that you have to handle this Api in a different way for android api below API 4 (1.6)and for the Android API 5 (2.0) and higher:
I will provide you some good links that will help you:

How to get contact id by phone number

I query the phone's calllog into a ListView. So when the user long clicks an item, a dialog comes up with options, including "View contact". To be able to view the contact the intent needs the contact id.
My problem is that I not always get to see the right contact. I click on Peter, and Peter's contact sheet comes up. I click on Sarah, and Jason's contact sheet comes up.
I must have been using this code the wrong way. Please help.
ContentResolver contentResolver = getContentResolver();
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phone));
Cursor cursor = contentResolver.query(uri, new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID}, null, null, null);
if(cursor!=null) {
while(cursor.moveToNext())
{
String contactName = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
contactid2 = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup._ID));
}
cursor.close();
}
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + contactid2));
startActivity(intent_contacts);
Maybe what I need is not the PhoneLookup._ID, but some other ID.
I also tried Felipe's answer here, same happens.
Edit:
on a HTC Desire HD (2.3.5) I get the proper contacts in 99% of the
cases.
on a ZTE Blade (2.2) I get the proper contacts in 60% of the cases.
on a Samsung Galaxy Ace (2.3.3) I get the proper contacts in 5% of the cases.
What the hell is going on???

After digging myself into theme, I found sven's help on googlegroups. The problem was that I was using a depracated intent. I read through many pages on the developer site, I must have missed it somehow.
I also post the full code.
contactid26 = null;
ContentResolver contentResolver = getContentResolver();
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phonenumintolist));
Cursor cursor =
contentResolver.query(
uri,
new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID},
null,
null,
null);
if(cursor!=null) {
while(cursor.moveToNext()){
String contactName = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
contactid26 = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup._ID));
}
cursor.close();
}
if (contactid26 == null) {
Toast.makeText(DetailedCallHistory.this, "No contact found associated with this number", Toast.LENGTH_SHORT).show();
}
else {
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(contactid26)));
//Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + contactid26));
startActivity(intent_contacts);
}

Here in this case i am going to show you that how to get the ID, and
Name of any contact no, which you have enter and want to search, For
Example if you enter a no and want to search its Name and id then use
this code, it is working 100%, if you want further modification in
this, then you can tell me
Uri lookupUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,Uri.encode(phnno.getText().toString()));//phone no
String[] proj = new String[]
{///as we need only this colum from a table...
Contacts.DISPLAY_NAME,
Contacts._ID,
};
String id=null;
String sortOrder1 = StructuredPostal.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor crsr = getContentResolver().query(lookupUri,proj, null, null, sortOrder1);
while(crsr.moveToNext())
{
String name=crsr.getString(crsr.getColumnIndex(Contacts.DISPLAY_NAME));
id = crsr.getString(crsr.getColumnIndex(Contacts._ID));
Toast.makeText(this,"Name of this cntct is : " +name +"\n id is : "+id ,Toast.LENGTH_SHORT).show();
}
crsr.close();

Android: strange thing about loading contact info

I created an app. It is working on htc desire hd, but when i tested it on ZTE Blade, a strange problem appeared. In my app when user selects a contact name from a spinner a menu appears. In the menu the user can send sms to the user, call him/her or just look at his/her contact info. On HTC Desire HD, everything is working fine. On ZTE there seems to be an exasperating problem with the contact info button: In certain cases when user selects a contact and wants to see his contact info, some other contact's info is shown. So I select Pete from my spinner but I get Dave's contact info. In other cases I select Tom from the spinner and I get Tom's contact info. The problem is not existing on my HTC. I couldn't figure out what causes the problem. By the way, my contact list on HTC is populated also from gmail and facebook and the app still working fine, while the contact list of the ZTE has never seen any gmail or facebook accounts (i am not entirely sure about this).
This is the code i am using to get to the contact info:
infobtn.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0)
{
while (cur.moveToNext()) {
id_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (name_contact.equals(name1))
{
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{id_contact}, null);
id_contact2 = id_contact;
while (pCur.moveToNext()){
}
pCur.close();
}
}
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + id_contact2));
startActivity(intent_contacts);
}
}
});

I have similar problems in my application. The app is a widget that give possibility to use favorites contacts in fast way. User creates new widget and assigns contact to it. When he clicks on widget he is able to make common contact actions - call, sms, edit, etc.
Some users send report like this one:
"I select about 4 contacts and the app shows 4 but only one of them right 3 others is same contact which I didnt even picked".
"Why does the wrong contact show when picked? On my droid incredible"
I can't reproduce the problem on my side. I have tried several different devices, tried to make import/export contacts - no results.
Anyway, i have some ideas about source of the problem.
My application uses lookup keys to store contacts, according to sdk. So, when user picks up a contact, application stores contact lookup key. Then it uses this lookup key to get Contact ID for this contact. After that, it uses ONLY received Contact ID in all other functions. So does your function - it uses only Contact ID in sub-query.
The question is: is it possible that different contacts (with different lookup keys) have same Contact ID? It looks like it's possible on some devices in rare cases... If so, we need to use Contact ID + lookup key always together to identify contact. (update: the suggestion was incorrect. Lookup key can be changed after contact info modification, you won't find contact).
As I understand, you are able to reproduce the problem on your side. I would suggest to change your code in such way:
infobtn.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0)
{
while (cur.moveToNext()) {
id_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String lookup_key = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
if (name_contact.equals(name1))
{
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ? AND " + ContactsContract.CommonDataKinds.Phone.LOOKUP_KEY + " = ?", new String[]{id_contact, lookup_key}, null);
id_contact2 = id_contact;
while (pCur.moveToNext()){
}
pCur.close();
}
}
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + id_contact2));
startActivity(intent_contacts);
}
}
});
and try to reproduce the problem again.

You can see this link, It's very good: http://www.vtutorials.info/2014/08/working-with-android-contacts-how-to.html
private Map<Long, ArrayList<LocalContactInfo>> queryAllPhones(ContentResolver contentresolver)
{
HashMap<Long, ArrayList<LocalContactInfo>> hashmap = new HashMap<Long, ArrayList<LocalContactInfo>>();
Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
Cursor cursor = contentresolver.query(PhoneCONTENT_URI, null, null, null, null);
do
{
if (!cursor.moveToNext())
{
cursor.close();
return hashmap;
}
long l = cursor.getLong(cursor.getColumnIndex(Phone_CONTACT_ID));
String s = cursor.getString(cursor.getColumnIndex(NUMBER));
LocalContactInfo temp = new LocalContactInfo(String.valueOf(l), "", s, "", 1);
if (hashmap.containsKey(Long.valueOf(l))){
((List<LocalContactInfo>)hashmap.get(Long.valueOf(l))).add(temp);
} else{
ArrayList<LocalContactInfo> arraylist = new ArrayList<LocalContactInfo>();
arraylist.add(temp);
hashmap.put(Long.valueOf(l), arraylist);
}
} while (true);
}
And:
public List<LocalContactInfo> doloadContacts() {
List<LocalContactInfo> _return = new ArrayList<LocalContactInfo>();
Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
String _ID = ContactsContract.Contacts._ID;
String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;
ContentResolver contentResolver = mContext.getContentResolver();
Map<Long, ArrayList<LocalContactInfo>> map = queryAllPhones(contentResolver);
Cursor cursor = contentResolver.query(CONTENT_URI, null,null, null, null);
if(cursor == null || cursor.getCount()==0){
return _return;
}
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
Long contact_id = cursor.getLong(cursor.getColumnIndex( _ID ));
String fullname = cursor.getString(cursor.getColumnIndex( DISPLAY_NAME )).trim();
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex( HAS_PHONE_NUMBER )));
if (hasPhoneNumber > 0 && map.get(contact_id) != null){
Object obj = ((List<LocalContactInfo>)map.get(contact_id)).get(0);
if(obj instanceof LocalContactInfo){
LocalContactInfo _temp = (LocalContactInfo)obj;
_return.add(new LocalContactInfo(String.valueOf(contact_id), fullname, _temp.getNumberPhone(), "",hasPhoneNumber));
}
}
}
}
return _return;
}

instead of using "contacts/people/xxx", try using contactsContract.Contacts.CONTENT_URI.
basically, you want to replace.
Uri contactUri = Uri.parse("content://contacts/people/" + id_contact2));
with
Uri contactUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI,
id_contact2);
Another thing to note is that "id_contact2" may be changed if a sync occurs before you use it (like when google sync merges a contact). To prevent this, it might be better to use a LookupKey instead.
ContactsContract.Contacts.LOOKUP_KEY
and retrieve using
Uri contactUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI,
yourContactLookupKey);
