Fetching more than 10000 contacts from android device - android

I want to retrieve >10000 contacts from the android device. To fetch that much contact it takes about 8-10 min. Is there any other possible way to do this. I have implemented a method its working fine but when it comes to large number of contacts it taking it time to fetch the contacts.
ContentResolver cr = getActivity().getApplication().getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
int phoneType = pCur.getInt(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.TYPE));
String phoneNumber = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
phoneNumber = phoneNumber.replace(" ","");
phoneNumber = phoneNumber.replace("-","");
boolean addNumber = stringCheck(phoneNumber,symbols);
if (!addNumber){
if (phoneNumber.length() == 10){
addContact(phoneNumber,phoneType,name);
}else if (phoneNumber.length() == 11){
phoneNumber = phoneNumber.substring(1);
addContact(phoneNumber,phoneType,name);
}else if (phoneNumber.length() == 12){
phoneNumber = phoneNumber.substring(2);
addContact(phoneNumber,phoneType,name);
}else if (phoneNumber.length() == 13){
phoneNumber = phoneNumber.substring(3);
addContact(phoneNumber,phoneType,name);
}
}
}
pCur.close();
}
}
}

If 900 out of the 1000 contacts have phone numbers, you're currently querying the DB 901 times, you can reduce it to only two queries:
Give me all contacts information
Give me all phone numbers
Then you use the contact-id field on both to match the phone to the right contacts.
Also, as noted in other answers, you really should add projection to all your queries to improve performance.
Another improvement you can make is to avoid runtime cur.getColumnIndex() calls, if you have a projection, you should already know the index - so use it hard-coded
Map<Long, List<String>> phones = new HashMap<>();
ContentResolver cr = getActivity().getApplication().getContentResolver();
// First build a mapping: contact-id > list of phones
Cursor cur = cr.query(Phone.CONTENT_URI, new String[] { Phone.CONTACT_ID, Phone.Number }, null, null, null);
while (cur != null && cur.moveToNext()) {
long contactId = cur.getLong(0);
String phone = cur.getString(1);
List list;
if (phones.contains(contactId)) {
list = phones.get(contactId);
} else {
list = new ArrayList<String>();
phones.put(contactId, list);
}
list.add(phone);
}
cur.close();
// Next query for all contacts, and use the phones mapping
cur = cr.query(Contacts.CONTENT_URI, new String[] { Contacts._ID, Contacts.DISPLAY_NAME }, null, null, null);
while (cur != null && cur.moveToNext()) {
long id = cur.getLong(0);
String name = cur.getString(1);
List<String> contactPhones = phones.get(id);
addContact(id, name, contactPhones);
}

Keep your fetching process in doInBackground method of AyncTask and then display it. And get only those info which is required first, eg, Contact Name and ID.
refer this ans for more clarification:
Fetching a large number of contacts

In order to fetch large number of contacts you must be fetching the contacts in the form of pages by using rest API.
For example page size of contacts is 100.
One possible approach:
If you are showing the contacts in the listview then you can fetch the data while user is scrolling the list. For that You have to set the threshold position of the list i.e. 80, So when user reaches at 80th position while scrolling you can hit your rest API for next page to fetch the new contacts and add those contacts in the listview.
From your comments i can see you want all the contacts in order to move forward.For this you can start an intent service when app is launched. This service will fetch all the contacts and store them. You can use them as per your needs

Here some optimization for speed up
String[] select = new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER};
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, select, null, null, null);
String[] selectOnly = new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.TYPE};
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
selectOnly,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
Do your number check, length check in server side if possible. Do it in Async task.

How to fetch all contacts from local phonebook and google contacts together?

I am trying to fetch contacts from the phonebook in my Android application. But it fetches the contacts that are present only in the local phone storage. I need to fetch all the contacts including the ones synced to the device using various accounts like Google. That is currently not happening. I am using a RecyclerView to display the contacts fetched.
I have tried using https://github.com/mirrajabi/rx-contacts2 library for fetching asynchronously. But that doesn't include Google contacts as well. Then I tried using Android's built-in CotentResolver
Contact contact;
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
if (cursor != null) {
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
if (hasPhoneNumber > 0) {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contact = new Contact(Long.parseLong(id));
contact.setDisplayName(name);
Cursor phoneCursor = contentResolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id},
null);
if (phoneCursor != null) {
if (phoneCursor.moveToNext()) {
String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Set<String> phoneNumbers = new HashSet<>();
phoneNumbers.add(phoneNumber);
contact.setPhoneNumbers(phoneNumbers);
}
phoneCursor.close();
}
Cursor emailCursor = contentResolver.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
if (emailCursor != null) {
while (emailCursor.moveToNext()) {
String emailId = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emailCursor.close();
}
listContacts.add(contact);
}
}
}
cursor.close();
}
Currently, I am trying to fetch the contacts synchronously and it hangs up the main thread. It would be really helpful if you could suggest some ways to do that asynchronously. When doing so I also require a trigger to know when the task is completed.
Your code should work on all contacts synced to the device, including Google contacts (assuming the Google account is installed, and the contacts sync is enabled).
However, your code has some bugs, and can be greatly improved, currently for a device with 500 contacts, you are doing ~1000 queries.
All the data you need is on a single table called Data so you can get everything in a single quick query, see here:
Map<Long, Contact> contacts = new HashMap<>();
String[] projection = {Data.CONTACT_ID, Data.DISPLAY_NAME, Data.MIMETYPE, Data.DATA1};
String selection = Data.MIMETYPE + " IN ('" + Phone.CONTENT_ITEM_TYPE + "', '" + Email.CONTENT_ITEM_TYPE + "')";
Cursor cur = cr.query(Data.CONTENT_URI, projection, selection, null, null);
while (cur.moveToNext()) {
long id = cur.getLong(0);
String name = cur.getString(1);
String mime = cur.getString(2); // email / phone
String data = cur.getString(3); // the actual info, e.g. +1-212-555-1234
// get the Contact class from the HashMap, or create a new one and add it to the Hash
Contact contact;
if (contacts.containsKey(id)) {
contact = contacts.get(id);
} else {
contact = new Contact(id);
contact.setDisplayName(name);
// start with empty Sets for phones and emails
contact.setPhoneNumbers(new HashSet<>());
contact.setEmails(new HashSet<>());
contacts.put(id, contact);
}
switch (mime) {
case Phone.CONTENT_ITEM_TYPE:
contact.getPhoneNumbers().add(data);
break;
case Email.CONTENT_ITEM_TYPE:
contact.getEmails().add(data);
break;
}
}
cur.close();
Notes:
I've changed your listContacts to a HashMap called contacts so we can quickly find an existing contact
I've added setEmails, getPhoneNumbers and getEmails to your Contact class

Show only a certain number of contacts

I have developed a program that shows a list of contacts from my phone book.
For this I use the following code:
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
null,
ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1'",
null,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
if (cursor != null && cursor.getCount() > 0) {
while (cursor.moveToNext()) {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(id));
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + id,
null,
null);
if (phones != null) {
while (phones.moveToNext()) {
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactList.add(new Contact(name, phoneNumber, id));
}
phones.close();
}
}
cursor.close();
}
adapter = new ContactAdapter(contactList, R.layout.contacts_list_item, getApplicationContext());
recyclerView.setAdapter(adapter);
Everything works, and the program displays all contacts from my phone book, but I want a certain number of contacts to be displayed. For example:
I open the program and load the first 50 contacts from the phone book, after scrolling, the next 50 contacts are loaded to the end of the list. and so on
Use below code that has limit cause. Replace your code with below
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
null,
ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1' ",
null,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE LOCALIZED ASC LIMIT 10");
It will get first 10 records. And in pull to refresh implementation, get more records on call back event of pull to refresh. Hope this will help you
I assume the reason you want this is because loading all contacts is very slow.
The reason it's very slow is because you currently have 1 query per contact, so if a user has 500 contacts, you'll need to run 500 queries.
You can reduce the number of queries to just one, then I assume you won't need the limit thing.
String[] projection = { Phone.CONTACT_ID, Phone.DISPLAY_NAME, Phone.NUMBER };
Cursor phones = getContentResolver().query(Phone.CONTENT_URI, projection, null, null, Phone.DISPLAY_NAME + " ASC");
while (phones.moveToNext()) {
String name = phones.getString(1);
String phone = phones.getString(2);
Long id = phones.getLong(0);
contactList.add(new Contact(name, phone, id));
}
phones.close();
If you want to display only one item per contact, and not per phone, you can change your contactList field to be a HashMap<Long, Contact> instead of a List, and add newly found phones to an existing Contact object if it already exists in the Map.
Something like:
Contact contact = allContacts.get(id);
if (contact == null) {
contact = new Contact(name, phone, id);
allContacts.put(id, contact);
} else {
contact.addPhone(phone); // you'll need to implement this
}

Get only numbers shown in the android contactbook

I want to filter what numbers I am getting from Android based on which contacts the user chose to display in his contact book. (For example only contacts saved on the device when all other contacts are excluded)
I read here that you can do this by using
Uri queryUri = ContactsContract.Contacts.CONTENT_URI;
I use following code to read the contacts and I allways get every contact, phone, SIM, etc..
//https://stackoverflow.com/questions/16651609/how-to-display-phone-contacts-only-exclude-sim-contacts
// http://www.higherpass.com/Android/Tutorials/Working-With-Android-Contacts/1/
ContentResolver cr = currentActivity.getContentResolver();
Uri queryUri = ContactsContract.Contacts.CONTENT_URI;
Cursor cur = cr.query(queryUri,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) { //Are there still contacts?
//See if the contact has at least one number
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
String id = cur.getString( cur.getColumnIndex(ContactsContract.Contacts._ID) );
String name = cur.getString( cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME) );
ArrayList<String> numbers = new ArrayList<String>();
//Read numbers:
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
numbers.add( pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)) );
Log.e("Contactbook", "The latest added number is: " + numbers.get(numbers.size()-1) );
}
pCur.close();
}
}
}
What am I missing? This code still gives me both SIM and phone contacts to the log.
Edit: To clarifify, in the contactbook you got the "Display options". In there ist the "select contacts to display"-option, and I want to read the contacts that are shown based on the users choice there. So if a user choses to show only SIM-contacts, read only SIM-contacts, if he choses to only show Phone-Contacts, show onyl phone contacts etc...
Try with following "selection".
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ?";
From Android docs:
public static final String IN_VISIBLE_GROUP: An indicator of whether this contact is supposed to be visible in the UI. "1" if the contact has at least one raw contact that belongs to a visible group; "0" otherwise.
This should be your "selection" argument in query API.
Update: I tried below code on Android-2.3(I know it is old device, but right now Don't have newer device with me).
final ContentResolver cr = getContentResolver();
String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME };
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ?" ;
String[] Args = { "1" };
final Cursor contacts = cr.query(
ContactsContract.Contacts.CONTENT_URI, projection,
selection,Args ,
null);
This could be a long operation (depending on no. of contacts), hence you should use CursorLoader class (A loader that queries the ContentResolver and returns a Cursor) for this.
cursorLoader.loadInBackground();
This will be called on a worker thread to perform the actual load and to return the result of the load operation.
You can easily create two Arrays for each kind of contacts
ArrayList<String> simContacts = new ArrayList<>();
//get all sim contacts
Uri simUri = Uri.parse("content://icc/adn");
Cursor cursorSim = getContext().getContentResolver().query(simUri, null, null, null, null);
while (cursorSim.moveToNext()) {
simContacts.add(cursorSim.getString(cursorSim.getColumnIndex("name")));
}
}
ArrayList<String> allContacts = new ArrayList<>();
//get all contacts
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cursor != null && cursor.getCount() > 0) {
while (!cursor.isAfterLast()) {
String phoneNumber = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
String displayNameColumn = Utils.hasHoneycomb() ? ContactsContract.Contacts.DISPLAY_NAME_PRIMARY : ContactsContract.Contacts.DISPLAY_NAME;
String displayName = cursor.getString(cursor.getColumnIndexOrThrow(displayNameColumn));
//check if simContacts Array contains this particular name
if (!simContacts.contains(displayNameColumn){
allContacts.add(displayNameColumn);
}
}
}
This is just a working example,of course you can modify to your needs.You can parse more contact fields and make more complication queries.

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:

Getting a Photo from a Contact

Android loading contacts is too slow

in my app there are 5 spinners populated with the contacts in the phone. I am using the code below to populate an array with the contacts and then populate the spinners with the items of the array (just 1 spinner here).
When user opens the app the spinners are populated so the user can select one name for each spinner.
Thing is, it takes around 3 secs to load the layout with the spinners when user opens the app. After playing with the code i figured out that no matter how may spinners are in the app, the source of the problem is the code that populates the array with the contacts.
I also found the cause of the slowliness: i ran the app on my brothers phone and there it opened as fast as it should. He has only 30 contacts in the phone, while I have around 500, most of them are Facebook contacts. So how can I help this situation?
Here is the problem, independently of the number of spinners. In case of too many contacts, this gets slow:
contactName = null;
final Context context = getApplicationContext();
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0)
{
while (cur.moveToNext()) {
String idc = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String namec = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{idc}, null);
while (pCur.moveToNext()) {
contactName = pCur.getString(pCur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
myArr.add(contactName);
}
pCur.close();
}
}
}
myArr.add("");
Collections.sort(myArr);
This is how I populate each spinner (and make them show the earlier selected name):
Spinner sp1 = (Spinner) findViewById(R.id.Spinner01);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, myArr);
sp1.setAdapter(adapter1);
sp1.setOnItemSelectedListener(new MyOnItemSelectedListener1());
mprefs = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
val1 = mprefs.getString("value1", "No name");
if (!val1.equals("No name"))
{
for (int i=0; i<myArr.size(); i++)
{
if (val1.equals(myArr.get(i)))
{
num = i;
}
}
sp1.setSelection(num);
}
else
{
sp1.setSelection(0);
}
Solution based on the idea of Jesse van Assen:
Turned out that the problem was the second query. I deleted this one and created a "projection" variable for the columns i needed:
final String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.HAS_PHONE_NUMBER
};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + "='1'";
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, projection, selection, null, null);
if (cur.getCount() > 0)
{
while (cur.moveToNext()) {
String idc = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String namec = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
myArr.add(namec);
}
}
So now I have one query that collects only the needed records. However it was slow even with the queried dataset AND with the second query. The real solution was to remove the second query, however collecting less record than the whole database is a great idea.
I would say that the way you query your contacts data is wrong.
It looks like you're fetching ALL your contacts with all the contact's data from the database, and then filtering the contacts in a while loop. I would suggest doing this from within the query, something like this (not tested):
Cursor cur = cr.query(
ContactsContract.Contacts.CONTENT_URI,
new String[] { "_ID", "DISPLAY_NAME" },
"HAS_PHONE_NUMBER = ?", new String[] { "1" },
null);
Your Spinners would populate a lot faster if you used a break to jump out of your for-loop once you assign
num = i
