Android cursor return empty contacts

I need to get all contacts that have at least a phone number. Android contacts may be picked from many accounts like gmail,skype,vibe etc. I made the classes i need to get the contacts i need. My problem that it gets anyway contacts that don't have at least 1 phone number and shows just their name and avatar. Can any1 say what I am doing wrong in my code? My code source is shared below.

Pick a number from calllog without repeating the same number

I want user to select a number from calllog and that number get selected and come in the activity. So I created custom calllog list. I used this code but it is not showing the call log list in right order
first thing it is showing the callhistory of the first number fully that it gets in the calllog list
second I wnt to show the name also, I tried a lot but I am not able to do
Can anyone tell what amendments i make in this code to make it right
The code I used is:
String[] callLogFields = { android.provider.CallLog.Calls._ID,
android.provider.CallLog.Calls.NUMBER,
android.provider.CallLog.Calls.CACHED_NAME };
String viaOrder = android.provider.CallLog.Calls.DATE + " DESC";
String WHERE = android.provider.CallLog.Calls.NUMBER + " >0"; /*filter out private/unknown numbers */
final Cursor callLog_cursor = this.getContentResolver().query(
android.provider.CallLog.Calls.CONTENT_URI, callLogFields,
WHERE, null, viaOrder);
AlertDialog.Builder myversionOfCallLog = new AlertDialog.Builder(this);
android.content.DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int item) {
callLog_cursor.moveToPosition(item);
Log.v("number", callLog_cursor.getString(callLog_cursor
.getColumnIndex(android.provider.CallLog.Calls.NUMBER)));
callLog_cursor.close();
}
};
myversionOfCallLog.setCursor(callLog_cursor, listener,
android.provider.CallLog.Calls.NUMBER);
myversionOfCallLog.setTitle("Choose from Call Log");
myversionOfCallLog.create().show();

You can add the Contact Numbers in a Set, which will prevent adding duplicate contact numbers. Then add the Set's data to listview as you want.
Set<String> setNumbers = new HashSet<String>();
String callNumber = cursor.getString(cursor.getColumnIndex(
android.provider.CallLog.Calls.NUMBER));
setNumbers.add(callNumber);
Hope this helps.

For saving numbers without duplicates, as MysticMagic suggested, use 'Set' as per the link given in the comment.
For getting the contact name from the phone number, use code :
(Reference)
private String getContactName(Context context, String number) {
String name = null;
// define the columns I want the query to return
String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
Log.v(TAG, "Started uploadcontactphoto: Contact Found # " + number);
Log.v(TAG, "Started uploadcontactphoto: Contact name = " + name);
} else {
Log.v(TAG, "Contact Not Found # " + number);
}
cursor.close();
}
return name;
}
Also refer here for another method to fetch name in phone call history
Uri allCalls = Uri.parse("content://call_log/calls");
Cursor c = managedQuery(allCalls, null, null, null, null);
String num= c.getString(c.getColumnIndex(CallLog.Calls.NUMBER));// for number
String name= c.getString(c.getColumnIndex(CallLog.Calls.CACHED_NAME));// for name
String duration = c.getString(c.getColumnIndex(CallLog.Calls.DURATION));// for duration
int type = Integer.parseInt(c.getString(c.getColumnIndex(CallLog.Calls.TYPE)));// for call type, Incoming or out going

Finally this is the code that worked with the help of MysticMagic and Nishanthi Grashia
Set setA;
setA = new HashSet();
public void getCallLog() {
try {
final String[] projection = null;
final String selection = null;
final String[] selectionArgs = null;
final String sortOrder = "DATE DESC";
final Cursor cursor = this.getContentResolver().query(
Uri.parse("content://call_log/calls"), projection,
selection, selectionArgs, sortOrder);
if (cursor != null) {
// Loop through the call log.
while (cursor.moveToNext()) {
// Common Call Log Items
String callNumber = cursor
.getString(cursor
.getColumnIndex(android.provider.CallLog.Calls.NUMBER));
setA.add(callNumber);
}
generateList();
}
} catch (Exception e) {
}
}

Fetching contacts in android is very slow

I had written a code to fetch contact name, phone number and image from Contacts and to display it on a listview in android. It's working fine but taking more time to load. I had tried to use multi-threading in some parts of the code. But the loading time is not decreased.
Here is the onCreate() method:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lvDetail = (ListView) findViewById(R.id.listView1);
fetchcontacts();
lvDetail.setAdapter(new MyBaseAdapter(context, myList));
}
Here is the code for fetch contacts:
private void fetchcontacts() {
// TODO Auto-generated method stub
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
int count = cursor.getCount();
if (count > 0) {
Toast.makeText(context, "count >0", Toast.LENGTH_SHORT).show();
while (cursor.moveToNext()) {
String columnId = ContactsContract.Contacts._ID;
int cursorIndex = cursor.getColumnIndex(columnId);
String id = cursor.getString(cursorIndex);
name = cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Toast.makeText(context, "Toast 1", Toast.LENGTH_SHORT).show();
int numCount = Integer.parseInt(cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
if (numCount > 0) {
Toast.makeText(context, "Toast 2", Toast.LENGTH_SHORT).show();
Cursor phoneCursor = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
CommonDataKinds.Phone.CONTACT_ID+" = ?", new String[] { id
}, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
while (phoneCursor.moveToNext()) {
Toast.makeText(context, "Toast 3", Toast.LENGTH_SHORT).show();
phoneNo = phoneCursor.getString(phoneCursor
.getColumnIndex(ContactsContract.CommonDataKinds.
Phone.NUMBER));
String image_uri = phoneCursor
.getString(phoneCursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
if (image_uri != null) {
Toast.makeText(context, "Toast 4", Toast.LENGTH_SHORT).show();
System.out.println(Uri.parse(image_uri));
try {
bitmap = MediaStore.Images.Media
.getBitmap(this.getContentResolver(),
Uri.parse(image_uri));
// sb.append("\n Image in Bitmap:" + bitmap);
// System.out.println(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Toast.makeText(context, name, Toast.LENGTH_SHORT).show();
getDataInList(name,phoneNo,bitmap);
name=null;
phoneNo=null;
Drawable myDrawable = getResources().getDrawable(R.drawable.star1);
bitmap = ((BitmapDrawable) myDrawable).getBitmap();
}
phoneCursor.close();
}
}
}
Here the setAdapter() function of the listview is working after fetching all the contacts to an ArrayList. do anyone have idea about how to display the contacts during fetching contacts? any sample code?

1.Read the Columns from the Cursor which you required only ,According to your requirement you just need _ID,HAS_PHONE_NUMBER,DISPLAY_NAME ,so change the Cursor reading
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI,
new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
ContactsContract.Contacts.DISPLAY_NAME }, null, null,
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
2.Dont do the time taking process in the UI thread..Use AsyncTask instead
Note : This two steps will resolve to some extent..but not completely

I made it by reduce repeated query wich is expensive. Best of my solution is that method found all mobile phones and email for each contact and insert to list for every contact values. It is fast as storm now :)
//contact entity
public class MobileContact {
public String name;
public String contact;
public Type type;
public MobileContact(String contact, Type type) {
name = "";
this.contact = contact;
this.type = type;
}
public MobileContact(String name, String contact, Type type) {
this.name = name;
this.contact = contact;
this.type = type;
}
public enum Type {
EMAIL, PHONE
}
#Override
public String toString() {
return "MobileContact{" +
"name='" + name + '\'' +
", contact='" + contact + '\'' +
", type=" + type +
'}';
}
}
// method for collect contacts
public List<MobileContact> getAllContacts() {
log.debug("get all contacts");
List<MobileContact> mobileContacts = new ArrayList<>();
ContentResolver contentResolver = context.getContentResolver();
// add all mobiles contact
Cursor phonesCursor = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.CONTACT_ID}, null, null, null);
while (phonesCursor != null && phonesCursor.moveToNext()) {
String contactId = phonesCursor.getString(phonesCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
String phoneNumber = phonesCursor.getString(phonesCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)).replace(" ", "");
mobileContacts.add(new MobileContact(contactId, phoneNumber, MobileContact.Type.PHONE));
}
if (phonesCursor != null) {
phonesCursor.close();
}
// add all email contact
Cursor emailCursor = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Email.DATA, ContactsContract.CommonDataKinds.Email.CONTACT_ID}, null, null, null);
while (emailCursor != null && emailCursor.moveToNext()) {
String contactId = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID));
String email = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
mobileContacts.add(new MobileContact(contactId, email, MobileContact.Type.EMAIL));
}
if (emailCursor != null) {
emailCursor.close();
}
// get contact name map
Map<String, String> contactMap = new HashMap<>();
Cursor contactsCursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER}, null, null, ContactsContract.Contacts.DISPLAY_NAME);
while (contactsCursor != null && contactsCursor.moveToNext()) {
String contactId = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts._ID));
String contactName = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contactMap.put(contactId, contactName);
}
if (phonesCursor != null) {
phonesCursor.close();
}
// replace contactId to display name
for (MobileContact mobileContact : mobileContacts) {
String displayName = contactMap.get(mobileContact.name);
mobileContact.name = displayName != null ? displayName : "";
}
// sort list by name
Collections.sort(mobileContacts, new Comparator<MobileContact>() {
#Override
public int compare(MobileContact c1, MobileContact c2) {
return c1.name.compareTo(c2.name);
}
});
return mobileContacts;
}

The contacts in larse size use in backround task.
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number[i]));
ContentResolver contentResolver = getContentResolver();
Cursor search = contentResolver.query(uri, new String[]{ContactsContract.PhoneLookup._ID,
ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
try {
if (search != null && search.getCount() > 0) {
search.moveToNext();
name = search.getString(search.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
id = search.getString(search.getColumnIndex(ContactsContract.Data._ID));
System.out.println("name" + name + "id" + id);
/* tv_name.setText(name);
tv_id.setText(id);
tv_phone.setText(number);*/
}
} finally {
if (search != null) {
search.close();
}
}

Fastest way for me soo far .
ContentResolver cr = mContext.getContentResolver(); Cursor cursor= mContext.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, PROJECTION, "HAS_PHONE_NUMBER <> 0", null, null); if (cursor!= null) { final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); final int numberIndex = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER); final int idIndex= cursor.getColumnIndex(ContactsContract.Contacts._ID); String displayName, number = null, idValue; while (cursor.moveToNext()) {
displayName = cursor.getString(displayNameIndex);
idValue= cursor.getString(idIndex);
Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, "contact_id = '" + idValue + "'", null, null);
phones.moveToFirst();
try {
number = phones.getString(phones.getColumnIndex("data1"));
}
catch (CursorIndexOutOfBoundsException e)
{`
}
phones.close();
userList.add(new ContactModel(displayName , number , null , }

Trying to query contacts for detailed information.

I am trying to query the Contacts database for contacts information, I have designed the program in a way that only contacts with Birth Day details are fetched:
projection = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Event.CONTACT_ID,
ContactsContract.CommonDataKinds.Event.START_DATE,
ContactsContract.CommonDataKinds.Email.DATA,
};
where = ContactsContract.Data.MIMETYPE + "= ? AND " +
ContactsContract.CommonDataKinds.Event.TYPE + "=" + ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY;
selectionArgs = new String[] { ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE };
The Call:
getLoaderManager().initLoader(0, null, this);
And Finally I try to fetch the result:
public Loader<Cursor> onCreateLoader(int arg0, Bundle arg1) {
CursorLoader loader = new CursorLoader(this, uri, projection, where,
selectionArgs, null);
return loader;
}
#SuppressWarnings("unchecked")
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
Map<Date,String> BD = new HashMap<Date,String>();
while (cursor.moveToNext()) {
String id = cursor.getString(cursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Toast.makeText(getApplicationContext(), ""+id, 10000).show();
String displayBirthday = cursor
.getString(cursor
.getColumnIndex(ContactsContract.CommonDataKinds.Event.START_DATE));
String name = cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String DateStr=displayBirthday;
Date d = null;
try {
d = new SimpleDateFormat("yyyy-MM-dd", current).parse(DateStr);
} catch (ParseException e) {
e.printStackTrace();
}
java.sql.Date d1 = new java.sql.Date(d.getTime());
BD.put(d1, name);
}
TreeMap Sorted = new TreeMap<Date,String>(BD);
//new MagicCall().execute(Sorted);
}
However I do not get the phone number, it gives me the birth day field result in the toast message instead of the phone number, if I change it to email it still gives me the birthday detail. Please neglect the suppress warnings as this is a test project in which I have isolate the problem code.

dont panic dude just match list with thar birthdate and take one temp arraylist and when any name match then add in that temp arraylist and then show that list view according to that temp arraylist :) here i give u code and hint i think it will help u to achieve whatever u want...:)
ArrayList<String> matchname = new ArrayList<String>();
for(int l =0;l<contactarraylist.size();l++)
{
String keyname = contactarraylist[k];
if((keyname.trim().equals("birthdate_string")))
{
matchname.add(keyname);
}
}

how to put progress bar in starting of a new activity

i Have two activities A and B. i used intent to jump from A to B. now in B.
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.list_main);
LoadData();
}
now in LoadData(), i have to load a lot of data, wo i want that when it B starts, it show a Progress bar and after loading the data, it jumps back to my activity B. how can I do this???
here is my load function
public void LoadData(Context context)
{
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ ("1") + "'";
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
ContentResolver cr = getContentResolver();
// ContactsContract.Contacts.
// Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
// null, null, ContactsContract.Contacts.DISPLAY_NAME);
// Find the ListView resource.
Cursor cur;
cur = context.getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI,
null,
selection + " AND "
+ ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1",
null, sortOrder);
mainListView = (ListView) findViewById(R.id.mainListView);
// When item is tapped, toggle checked properties of CheckBox and
// Planet.
mainListView
.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
public void onItemClick(AdapterView<?> parent, View item,
int position, long id)
{
ContactsList planet = listAdapter.getItem(position);
planet.toggleChecked();
PlanetViewHolder viewHolder = (PlanetViewHolder) item
.getTag();
viewHolder.getCheckBox().setChecked(planet.isChecked());
}
});
// Create and populate planets.
planets = (ContactsList[]) getLastNonConfigurationInstance();
// planets = new Planet[10];
// planets.Add("asdf");
ArrayList<ContactsList> planetList = new ArrayList<ContactsList>();
String phoneNumber = null;
String phoneType = null;
count = cur.getCount();
contacts = new ContactsList[count];
if (planets == null)
{
if (cur.getCount() > 0)
{
planets = new ContactsList[cur.getCount()];
int i = 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)
{
// Query phone here. Covered next
Cursor pCur = cr
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[]
{ id }, null);
// WHILE WE HAVE CURSOR GET THE PHONE NUMERS
while (pCur.moveToNext())
{
// Do something with phones
phoneNumber = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
phoneType = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
Log.i("Pratik", name + "'s PHONE :" + phoneNumber);
Log.i("Pratik", "PHONE TYPE :" + phoneType);
}
pCur.close();
}
if (phoneNumber != null
&& !planetList.contains(new ContactsList(name,
phoneNumber)))
{
planets = new ContactsList[]
{ new ContactsList(name, phoneNumber) };
contacts[i] = planets[0];
planetList.addAll(Arrays.asList(planets));
}
phoneNumber = null;
i++;
}
}
// for (int i = 0; i < count; i++)
// {
// Log.d("New Selected Names : ", contacts[i].getName());
// }
}
// Set our custom array adapter as the ListView's adapter.
listAdapter = new PlanetArrayAdapter(this, planetList);
mainListView.setAdapter(listAdapter);
Adapter adptr;
adptr = mainListView.getAdapter();
}

Please try this
//////////////////////////////////////////////////////////////////
Edit Check It
public class LoadData extends AsyncTask<Void, Void, Void> {
ProgressDialog progressDialog;
//declare other objects as per your need
#Override
protected void onPreExecute()
{
progressDialog= new ProgressDialog(YourActivity.this);
progressDialog.setTitle("Please Wait..");
progressDialog.setMessage("Loading");
progressDialog.setCancelable(false);
progressDialog.show();
//do initialization of required objects objects here
};
#Override
protected Void doInBackground(Void... params)
{
LoadData();
//do loading operation here
return null;
}
#Override
protected void onPostExecute(Void result)
{
super.onPostExecute(result);
progressDialog.dismiss();
};
}
You can call this using
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.list_main);
LoadData task = new LoadData();
task.execute();
}

I am agree with Kanaiya's answer because upto the API level-10 it is fine to call long running tasks on UI thread. But from API-11, any task that takes longer time (nearly more than 5 sec) to complete must be done on background thread. The reason behind this is any task that takes 5 seconds or more on UI thread then ANR(Application Not Responding) i.e. force close happens. To do that we have create some background thread or simply make use of AsyncTask.

You just need to call your LoadData() method in another thread.
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.list_main);
mDailog = ProgressDialog.show(ActivityA.this, "",
"Loading data....!!!", true);
mDailog.show();
new Thread() {
#Override
public void run() {
try {
LoadData();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
}.start();
}
Inside your LoadData(), at the end of the method use a handler to send a message to dismiss the progress bar dialog.
Hope this will help you to avoid the complex logic using AsyncTask.

Try this.
public class BActivtiy extends Activity implements Runnable{
#Override
protected void onCreate(Bundle savedInstanceState) {

public void onItemClick(AdapterView<?> parent, View item, int position, long id) {
ContactsList planet = listAdapter.getItem(position);
planet.toggleChecked();
PlanetViewHolder viewHolder = (PlanetViewHolder) item.getTag();
viewHolder.getCheckBox().setChecked(planet.isChecked());
}
});
pd = ProgressDialog.show(BActivity.this, "Title", "Description", true);
Thread t = new Thread(BActivity.this);
t.start();
