android get contacts detail such as number and thumbnail

i use of this code that can get contact's number and contact's thumbnail , but this is not suitable and take to long to load and prepare contacts .
please help me to improve performance of this code :
List<Contact_Pojo> list = new ArrayList<Contact_Pojo>();
ContentResolver cr = getActivity().getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, Phone.DISPLAY_NAME + " ASC");
int i = 0;
if (cur.moveToFirst()) {
while (cur.moveToNext()) {
Cursor phoneCursor = getActivity()
.getContentResolver()
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER, },
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?",
new String[] { cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID)) },
null);
if (phoneCursor.moveToFirst()) {
Contact_Pojo personContact = new Contact_Pojo();
/*
* Id
*/
personContact.setId(cur.getString(1));
/*
* Name
*/
personContact
.setName(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
/*
* Photo ID
*/
personContact
.setImageUrl(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI)));
/*
* Number
*/
personContact.setNumber(phoneCursor.getString(0));
//
list.add(personContact);
}
phoneCursor.close();
}
}
cur.close();
return list;
Update 4/4/2015
it is slow because it has getting all column from contact provider , in this table has +20 column that take many time .

How about using AsyncTaskLoader,
write this code when you want to get contacts list
getLoaderManager() or getSupportLoaderManager().initLoader(int id, Bundle args, LoaderManager.LoaderCallbacks<D> loadingCallback)
public class LoadingCallback implements LoaderManager.LoaderCallbacks<Void> {
#Override
public Loader<Void> onCreateLoader(int i, Bundle bundle) {
// Show your dialog;
return new InitializeContactsTask(context, (ArrayList) contactList, mAdapter);
}
#Override
public void onLoadFinished(Loader<Void> voidLoader, Void aVoid) {
// UI Work here after background task and hide dialog.
}
#Override
public void onLoaderReset(Loader<Void> voidLoader) {
}
}
and
public class InitializeApplicationsTask extends AsyncTaskLoader<Void> {
#Override
protected void onStartLoading() {
forceLoad();
}
#Override
public Void loadInBackground() {
// Query the contacts here and return null
return null;
}
}

It's slow because, you are getting all column from contact provider, so use projection to get only those column which are required. like
String[] projection = {
ContactsContract.Contacts.DISPLAY_NAME
// this is just example, add fields that required
} ;
can you please tell me what is purpose of second query ? because here is my result of getting contact
and my method for getting all contact is
#SuppressLint("InlinedApi")
public void readContacts() {
long l1 = System.currentTimeMillis();
Log.d("DEBUG",
"starting readContacts() time " + l1);
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
Contact_pojo cp = new Contact_pojo();
String Contact_Id = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
String Contact_Name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String photothumb = "";
try {
photothumb = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));
if (photothumb != null
&& !photothumb.toString().equalsIgnoreCase("")) {
cp.setImageUri(photothumb);
}
} catch (Exception e) {
e.printStackTrace();
}
cp.setId(Contact_Id);
cp.setName(Contact_Name);
Cursor phones = cr.query(Phone.CONTENT_URI, null,
Phone.CONTACT_ID + " = " + Contact_Id, null, null);
while (phones.moveToNext()) {
String number = phones.getString(phones
.getColumnIndex(Phone.NUMBER));
int type = phones.getInt(phones.getColumnIndex(Phone.TYPE));
Log.d("DEBUG", "number " + number + " type " + type);
cp.setNumber(number);
}
phones.close();
contactList.add(cp);
}
}
long l2 = System.currentTimeMillis();
Log.d("DEBUG",
"Finished readContacts() time " + l2);
Log.d("DEBUG","Total contact loaded "+contactList.size()+" within "+ (l2 - l1) + "ms");
}

Don't use double query, this is taking too much time if device have lots of contacts and it's not working in some device also...
You can also fetch contact with single query..
Use below code..
public void fetchContacts()
{
String[] projection = new String[] {
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.HAS_PHONE_NUMBER,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID};
String _ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
String DISPLAY_NAME = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ? Contacts.DISPLAY_NAME_PRIMARY : Contacts.DISPLAY_NAME;
String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
Cursor cursor = mActivity.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, ContactsContract.CommonDataKinds.Phone.HAS_PHONE_NUMBER + "=?", new String[] { "1" },
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
System.out.println("contact size.."+cursor.getCount());
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
String contact_id = cursor.getString(cursor.getColumnIndex( _ID ));
String name = cursor.getString(cursor.getColumnIndex( DISPLAY_NAME ));
String phoneNumber = cursor.getString(cursor.getColumnIndex(NUMBER));
System.out.println(" name : "+name);
System.out.println(" number : "+phoneNumber);
}
}
}

How to get the outgoing call duration in real time?

I have a activity which is brought in front whenever there are any outgoing call. I need the outgoing call duration in real time and show it in my activity textview.
Is this possible to get the current duration if call is in offhook?

This can be done. You just have to Spy on Android Call Log Content Provider. To use a content provider, you just need to call the getContentResolver() method. Once you have a content resolver object, you can query it using SQL or any of the built in query functions. For example, in my Android App, I use a piece of code that looks like this:
String[] strFields = {
android.provider.CallLog.Calls.NUMBER,
android.provider.CallLog.Calls.TYPE,
android.provider.CallLog.Calls.CACHED_NAME,
android.provider.CallLog.Calls.CACHED_NUMBER_TYPE,
android.provider.CallLog.Calls.DURATION
};
String strOrder = android.provider.CallLog.Calls.DATE + " DESC";
Cursor mCallCursor = getContentResolver().query(
android.provider.CallLog.Calls.CONTENT_URI,
strFields,
null,
null,
strOrder
);

if (callType == OUTGOING_CALL_END || callType == INCOMING_CALL_END) {
Cursor cursorCallLogs = getRecentCallLogs(context.getContentResolver());
if (cursorCallLogs != null) {
cursorCallLogs.moveToLast();
do {
try {
String callNumber = cursorCallLogs.getString(cursorCallLogs.getColumnIndex("number"));
callNumber = utilS.getPhoneNumber(callNumber);
utilS.log("Phone NUmber", callNumber);
duration = (cursorCallLogs.getInt(cursorCallLogs.getColumnIndex("duration")) * 1000);
utilS.log("durationCall", "" + duration);
} catch (Exception e) {
e.printStackTrace();
}
}
while (cursorCallLogs.moveToPrevious());
}
}
public static Cursor getRecentCallLogs(ContentResolver cr) {
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
return null;
} else {
return cr.query(CallLog.Calls.CONTENT_URI, null, null, null, android.provider.CallLog.Calls.DATE + " DESC limit 1");
}
}

Fetching Phone Number from Contacts based on Name Android

I am developing an application, where I need to fetch the phone number from the contacts corresponding to the name provided. I have tried many codes but none of them seem to work.
Here is the code I'm currently using now
public static String getContactPhoneNumber(Context context, String contactName, int type) {
String phoneNumber = null;
String[] whereArgs = new String[] { contactName, String.valueOf(type) };
Log.d(TAG, String.valueOf(contactName));
Cursor cursor = context.getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.Contacts.DISPLAY_NAME + " = ? and "
+ ContactsContract.CommonDataKinds.Phone.TYPE + " = ?", whereArgs, null);
int phoneNumberIndex = cursor
.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER);
Log.d(TAG, String.valueOf(cursor.getCount()));
if (cursor != null) {
Log.v(TAG, "Cursor Not null");
try {
if (cursor.moveToNext()) {
Log.v(TAG, "Moved to first");
Log.v(TAG, "Cursor Moved to first and checking");
phoneNumber = cursor.getString(phoneNumberIndex);
}
} finally {
Log.v(TAG, "In finally");
cursor.close();
}
}
Log.v(TAG, "Returning phone number");
return phoneNumber;
}
On passing Contact Name (say: John Doe) and type (2 which is int value for Mobile Type), the phone number returned is null even though the contact "John Doe" exists in my contact list.
Please help!!!

Try this
instead of ContactsContract.CommonDataKinds.Phone.CONTENT_URI Pass
ContactsContract.Contacts.CONTENT_URI parameter to query method.

Get phone number of present incoming and outgoing call

I am making an app in which I have to retrieve the phone number and I am able to retrieve it but my problem is that I am getting phone number of last call rather than present call.My code is as follows:
projection = new String[]{Calls.NUMBER};
cur = context.getContentResolver().query(Calls.CONTENT_URI, projection, null, null, null);
cur.requery();
numberColumn = cur.getColumnIndex(Calls.NUMBER);
cur.requery();
cur.requery();
cur.requery();
cur.requery();
cur.moveToLast();
s = cur.getString(numberColumn);
String pathname = "/sdcard/" + s + ".amr";

As suggested by Krutix, the call LOG, is a LOG of finished phone calls which is written to by the dialer app after a call is finished. As such you will not find which number is currently dialing in the content provider.
Here is an implementation which will allow you to retrieve the phone number if it is an incoming phone call as incomingNumber and also when the call is FINISHED - note the Handler() code.
private class PhoneCallListener extends PhoneStateListener {
private boolean isPhoneCalling = false;
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if (TelephonyManager.CALL_STATE_RINGING == state) {
// phone ringing
Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
}
if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
// active
Log.i(LOG_TAG, "OFFHOOK");
isPhoneCalling = true;
}
if (TelephonyManager.CALL_STATE_IDLE == state) {
// run when class initial and phone call ended, need detect flag
// from CALL_STATE_OFFHOOK
Log.i(LOG_TAG, "IDLE number");
if (isPhoneCalling) {
Handler handler = new Handler();
//Put in delay because call log is not updated immediately when state changed
// The dialler takes a little bit of time to write to it 500ms seems to be enough
handler.postDelayed(new Runnable() {
#Override
public void run() {
// get start of cursor
Log.i("CallLogDetailsActivity", "Getting Log activity...");
String[] projection = new String[]{Calls.NUMBER};
Cursor cur = getContentResolver().query(Calls.CONTENT_URI, projection, null, null, Calls.DATE +" desc");
cur.moveToFirst();
String lastCallnumber = cur.getString(0);
}
},500);
isPhoneCalling = false;
}
}
}
}
And then add and initialise the listener in your onCreate or onStartCommand code:
PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager) this
.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener,
PhoneStateListener.LISTEN_CALL_STATE);

please modify your query with
cur = context.getContentResolver().query(Calls.CONTENT_URI,
projection, null, null, Calls.DATE +" desc");
cur.moveToFirst();
s = cur.getString(numberColumn);
it will give last call's phone number and there is no need requery so many times

Android: using registerContentObserver() to be notified as the contacts are changed

I'm using registerContentObserver() to be notified as the contacts are changed, but when I register for the content uri:People.CONTENT_URI and when I observe in the log cat I'm getting the notify as "false" even after changing the contact.
I have also overridden the deliverSelfNotification to true. What am I doing wrong?

Not sure what your asking, your question is a bit vague.
Here is how I listen out for changes in the SMS content provider, you may find it useful
String url = "content://sms/";
Uri uri = Uri.parse(url);
getContentResolver().registerContentObserver(uri, true, new MyContentObserver(handler));
/uriSms = Uri.parse("content://sms/inbox");
Cursor c = getContentResolver().query(uriSms, null,null,null,null);
//Log.d("COUNT", "Inbox count : " + c.getCount());
}
class MyContentObserver extends ContentObserver {
public MyContentObserver(Handler handler) {
super(handler);
}
#Override public boolean deliverSelfNotifications() {
return false;
}
#Override public void onChange(boolean arg0) {
super.onChange(arg0);
Log.v("SMS", "Notification on SMS observer");
Message msg = new Message();
msg.obj = "xxxxxxxxxx";
handler.sendMessage(msg);
Uri uriSMSURI = Uri.parse("content://sms/");
Cursor cur = getContentResolver().query(uriSMSURI, null, null,
null, null);
cur.moveToNext();
String protocol = cur.getString(cur.getColumnIndex("protocol"));
if(protocol == null){
Log.d("SMS", "SMS SEND");
int threadId = cur.getInt(cur.getColumnIndex("thread_id"));
Log.d("SMS", "SMS SEND ID = " + threadId);
getContentResolver().delete(Uri.parse("content://sms/conversations/" + threadId), null, null);
}
else{
Log.d("SMS", "SMS RECIEVE");
int threadIdIn = cur.getInt(cur.getColumnIndex("thread_id"));
getContentResolver().delete(Uri.parse("content://sms/conversations/" + threadIdIn), null, null);
}
}

If you are targeting anything newer than api level 3,
you should use ContactsContract.Contacts.CONTENT_URI.
and then it's just a matter of: getContentResolver().registerContentObserver(ContactsContract.Contacts.CONTENT_URI, true, contentObserver);
You will not know what has changed with this method though.
