Modifying starred contacts

I need (for practicing reasons) to change all the contacts to be starred. So I use this code to read all the contacts in a thread:
Looper.prepare(); //To avoid error: Can't create handler inside thread that has not called Looper.prepare
CursorLoader oCursorLoader = new CursorLoader(ContextoGlobal, ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
Cursor oCursor = oCursorLoader.loadInBackground();
int contactId = oCursor.getColumnIndex(ContactsContract.Contacts._ID);
contactId = oCursor.getColumnIndex(ContactsContract.RawContacts._ID);
int starred = oCursor.getColumnIndex(ContactsContract.Contacts.STARRED);
int number = oCursor.getColumnIndex(ContactsContract.Contacts.Data.DATA1);
int name = oCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
oCursor.moveToFirst();
if(oCursor.isAfterLast()==false) {
do {
String sId = oCursor.getString(contactId);
String phNumber = oCursor.getString(number);
String phName = oCursor.getString(name);
String sStarred = oCursor.getString(starred);
String s = sId + "\n" + phName + "\n" + phNumber + "\nStarred: " + sStarred;
} while (oCursor.moveToNext());
}
This code works and iterates through all the contacts in the device, displaying if they are starred or not.
My problem comes when I want to modify the starred field in the loop:
...
do {
String sId = oCursor.getString(contactId);
String phNumber = oCursor.getString(number);
String phName = oCursor.getString(name);
String sStarred = oCursor.getString(starred);
String s = sId + "\n" + phName + "\n" + phNumber + "\nStarred: " + sStarred;
ChangeStarred(sId, true); <-- HERE!!!!!!!!
} while (oCursor.moveToNext());
...
This is the ChangeStarred() function:
private boolean ChangeStarred(String sContactId, boolean bStarred){
ContentValues values = new ContentValues();
if(bStarred==true)
values.put(ContactsContract.Contacts.STARRED, 1);
else
values.put(ContactsContract.Contacts.STARRED, 0);
//int iAffectedRows = ContextoGlobal.getContentResolver().update(ContactsContract.Contacts.CONTENT_URI, values, ContactsContract.Contacts._ID + "= ?", new String[] { sContactId });
int iAffectedRows = ContextoGlobal.getContentResolver().update(ContactsContract.Contacts.CONTENT_URI, values, ContactsContract.RawContacts._ID + "= ?", new String[] { sContactId });
if(iAffectedRows == 0)
return false;
return true;
}
This function always returns FALSE. No rows are updated.
As you can see in the code comments, I have tried with Contacts._ID and RawContacts._ID
I also have WRITE_CONTACTS permission granted.

This is how I solved:
Looper.prepare(); //To avoid error: Can't create handler inside thread that has not called Looper.prepare
CursorLoader oCursorLoader = new CursorLoader(ContextoGlobal, ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
Cursor oCursor = oCursorLoader.loadInBackground();
int contactId = oCursor.getColumnIndex(ContactsContract.Contacts._ID);
int starred = oCursor.getColumnIndex(ContactsContract.Contacts.STARRED);
int name = oCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
oCursor.moveToFirst();
if(oCursor.isAfterLast()==false) {
do {
String sId = oCursor.getString(contactId);
String phName = oCursor.getString(name);
String sStarred = oCursor.getString(starred);
String s = sId + "\n" + phName + "\n" + "\nStarred: " + sStarred;
ChangeStarred(sId, true);
} while (oCursor.moveToNext());
}
And the ChangeStarred() function:
private boolean ChangeStarred(String sContactId, boolean bStarred) {
ContentValues contentValues = new ContentValues();
if(bStarred==true)
contentValues.put(ContactsContract.Contacts.STARRED, 1);
else
contentValues.put(ContactsContract.Contacts.STARRED, 0);
int iAffectedRows = ContextoGlobal.getContentResolver().update(ContactsContract.Contacts.CONTENT_URI, contentValues, ContactsContract.Contacts._ID + "=" + sContactId, null);
if(iAffectedRows > 0)
return true;
return false;
}

android: push sms As recieved in inbox using getContentResolver

on sms received , i have saved that sms in my database
now i want to move that sms into inbox
i used this code but it move it as sent by me
please help me to move it as a received sms
ListViewLogItem lm = listArray.get(position);
long datein = Long.parseLong(lm.getInboxTime());
Uri uri = Uri.parse("content://sms/");
ContentValues cv2 = new ContentValues();
cv2.put("address","+"+lm.getNumber());
cv2.put("date", datein);
cv2.put("read", 1);
cv2.put("type", 2);
cv2.put("body", lm.getSms());
getContentResolver().insert(Uri.parse("content://sms/inbox"), cv2);

Change:
cv2.put("type", 2);
To:
cv2.put("type", 1);
Because:
public static final int MESSAGE_TYPE_INBOX = 1;
public static final int MESSAGE_TYPE_SENT = 2;

You can use following method for deleting SMS from Inbox,
private void deleteMessage()
{
Cursor c = getContentResolver().query(SMS_INBOX, null, null, null, null);
//c.moveToFirst();
while (c.moveToNext())
{
System.out.println("Inside if loop");
try
{
String address = c.getString(2);
String MobileNumber = mainmenu.getParameterData().getMobileNumber().trim();
//Log.i( LOGTAG, MobileNumber + "," + address );
Log.i( LOGTAG, c.getString(2) );
if ( address.trim().equals( MobileNumber ) )
{
String pid = c.getString(1);
String uri = "content://sms/conversations/" + pid;
getContentResolver().delete(Uri.parse(uri), null, null);
stopSelf();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

Use thisvalues.put("status", SmsManager.STATUS_ON_ICC_UNREAD); . Status can be anything like read/unread/seen. I have keep it as unread.
Look at Message status
values.put("read", true); // As Read
and
values.put("read", false); // As Un Read
public class Message {
final Uri SMS_INBOX = Uri.parse("content://sms/inbox");
#SuppressWarnings("unused")
private ContentResolver resolver;
public Message(ContentResolver ConResolver){
resolver = ConResolver;
}
public String getMessage(int batas) {
Cursor cur = resolver.query(SMS_INBOX, null, null, null,null);
String sms = "Message >> \n";
int hitung = 0;
while (cur.moveToNext()) {
sms += "From :" + cur.getString(2) + " : " + cur.getString(11)+"\n";
if(hitung == batas)
break;
hitung++;
}
return sms;
}
public int getMessageCountUnread(){
Cursor c = resolver.query(SMS_INBOX, null, "read = 0", null, null);
int unreadMessagesCount = c.getCount();
c.deactivate();
return unreadMessagesCount;
}
public String getMessageAll(){
Cursor cur = resolver.query(SMS_INBOX, null, null, null,null);
String sms = "Message >> \n";
while (cur.moveToNext()) {
sms += "From :" + cur.getString(2) + " : " + cur.getString(11)+"\n";
}
return sms;
}
public String getMessageUnread() {
Cursor cur = resolver.query(SMS_INBOX, null, null, null,null);
String sms = "Message >> \n";
int hitung = 0;
while (cur.moveToNext()) {
sms += "From :" + cur.getString(2) + " : " + cur.getString(11)+"\n";
if(hitung == getMessageCountUnread())
break;
hitung++;
}
return sms;
}
public void setMessageStatusRead() {
ContentValues values = new ContentValues();
values.put("read",true);
resolver.update(SMS_INBOX,values, "_id="+SmsMessageId, null);
}
}

Cannot Read Calendar Event with Recurrence Rule

I created an event with repeat rule "FREQ=MONTHLY;BYMONTHDAY=16;COUNT=10". I saw the event on my two Android Calendars apps, and also on Google Calendar web site. I can read all other events from my app, but I do not see this event. Only difference is that this event has repeat rule. Here is my code for reading.
public static MyEvents readCalendarMyEvent(Context context,Date date1, Date date2, int calendarID)
{
try
{
Calendar calendar1 = Calendar.getInstance();
calendar1.setTime(date1);
Calendar calendar2 = Calendar.getInstance();
calendar2.setTime(date2);
Uri l_eventUri;
if (Build.VERSION.SDK_INT >= 8) {
l_eventUri = Uri.parse("content://com.android.calendar/events");
} else {
l_eventUri = Uri.parse("content://calendar/events");
}
ContentResolver contentResolver = context.getContentResolver();
String dtstart = "dtstart";
String dtend = "dtend";
String[] l_projection = new String[] { CalendarContract.Events.CALENDAR_ID,
CalendarContract.Events.TITLE, //1
CalendarContract.Events.DESCRIPTION,
CalendarContract.Events.DTSTART,
CalendarContract.Events.DTEND,
CalendarContract.Events.EVENT_LOCATION,
CalendarContract.Events.EVENT_TIMEZONE,//6
CalendarContract.Events.HAS_ALARM,
CalendarContract.Events.RRULE,
CalendarContract.Events.RDATE,

CalendarContract.Events.ALL_DAY,
CalendarContract.Events.ACCESS_LEVEL,
CalendarContract.Events.AVAILABILITY,
CalendarContract.Events.EXRULE,
CalendarContract.Events.EXDATE
};
String where = "(" + dtstart + ">"
+ calendar1.getTimeInMillis() + " and "
+ dtend + "<" + calendar2.getTimeInMillis() + " and "+
CalendarContract.Events.CALENDAR_ID + " = '" + String.valueOf(calendarID) +"')";
Cursor cursor= contentResolver.query(l_eventUri, l_projection, where, null,
"dtstart ASC");
cursor.moveToFirst();
// fetching calendars id
String str="";
MyEvents myEvents = new MyEvents();
for (int i = 0; i < cursor.getCount(); i++) {
int delete = cursor.getInt(15);
if( delete == 1)
{
cursor.moveToNext();
continue;
}
MyEvent myEvent = new MyEvent();
myEvent.ID = cursor.getInt(0);
myEvent.TITLE = cursor.getString(1);
myEvent.Note = cursor.getString(2);
str = cursor.getString(3);
if(str != null || str.length() <1)
{
myEvent.START_DATE = MillisecondsToDateTime(Long.parseLong(str));
myEvent.StartDate = getDate(Long.parseLong(str));
}
else
{
cursor.moveToNext();
continue;
}
str = cursor.getString(4);
if(str != null || str.length() <1)
myEvent.END_DATE = MillisecondsToDateTime(Long.parseLong(str));
myEvent.EVENT_LOCATION =cursor.getString(5);
myEvent.EVENT_TIMEZONE =cursor.getString(6);
myEvent.HAS_ALARM = cursor.getInt(7);
myEvent.RRULE = cursor.getString(8);
myEvent.RDATE = cursor.getString(9);
myEvent.ORGANIZER =cursor.getString(10);
myEvent.SELF_ATTENDEE_STATUS = cursor.getInt(11);
myEvent.GUESTS_CAN_MODIFY = cursor.getInt(12);
myEvent.EVENT_ID = cursor.getInt(13);
myEvent.ALL_DAY = cursor.getInt(14);
myEvent.GUESTS_CAN_INVITE_OTHERS= cursor.getInt(16);
myEvent.GUESTS_CAN_SEE_GUESTS= cursor.getInt(17);
myEvent.ALL_DAY= cursor.getInt(18);
myEvent.ACCESS_LEVEL= cursor.getInt(19);
myEvent.AVAILABILITY= cursor.getInt(20);
myEvent.EXRULE = cursor.getString(21);
myEvent.EXDATE = cursor.getString(22);
myEvents.Add(myEvent);
cursor.moveToNext();
}
return myEvents;
}
catch(Exception ex)
{
ex.printStackTrace();
}
return new MyEvents();
}

The problem was resolved. I made a mistake in the where clause. The following is correct on
String where = "(" + dtstart + ">"
+ calendar1.getTimeInMillis() + " and "
+ dtstart + "<" + calendar2.getTimeInMillis() + " and "+
CalendarContract.Events.CALENDAR_ID + " = '" + String.valueOf(calendarID) +"')";

Getting attendees details from Calendar Content Provider

Android get calendar event in tablet

I am using below code to get calendar events in my application. It's working fine in Android phones but when I try this code on Android tablet, my application crashes. So I don't know exactly what is the problem and why it is not working on tablets.

i have use

instead of
content://com.android.calendar/calendars
for the android tablet applications
