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;
}

Database is not retrieving all rows instead getting only unique rows

I am working on a code snippet where i am storing my json encoded data into a txt file,and using following method to separate all parts and adding them into database.
public boolean addAnswersFromJSONArray() {
boolean flag = false;
Answer answer = new Answer();
File sdcard = Environment.getExternalStorageDirectory();
File file = new File(sdcard, "user_live.txt");
FileReader fr;
JsonReader reader;
try {
fr = new FileReader(file);
reader = new JsonReader(fr);
reader.beginArray();
reader.setLenient(true);
while (reader.hasNext()) {
reader.beginObject();
while (reader.hasNext()) {
String name = reader.nextName();
if (name.equals("product_name")) {
answer.setProductName(reader.nextString());
} else if (name.equals("subject")) {
answer.setSubject(reader.nextString());
} else if (name.equals("month")) {
answer.setMonth(reader.nextString());
} else if (name.equals("year")) {
answer.setYear(reader.nextString());
} else if (name.equals("question")) {
answer.setQuestion(reader.nextString());
} else if (name.equals("answer")) {
answer.setAnswer(reader.nextString());
} else if (name.equals("question_no")) {
answer.setQuestion_no(reader.nextString());
} else if (name.equals("marks")) {
answer.setMarks(reader.nextString());
} else {
reader.skipValue();
}
}
answer.save(db);
reader.endObject();
flag = true;
}
reader.endArray();
reader.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
file.delete();
db.close();
}
return flag;
}
and then i am retrieving each fields departments,subjects,month and year,questions,answers,question_no, but while retrieving marks i am getting only unique entries that is 10 and 5....Ideally the size of one set is 18 so i m getting ArrayIndexoutOfBounds Exception.
//database calling part
marks = db.getMarksList(department, subject, month_year);
database method is,
public String[] getMarksList(String department, String subject,
String month_year) {
String month = month_year.split("-")[0];
String year = month_year.split("-")[1];
String whereClause = DEPARTMENT + " = '" + department + "'" + " AND "
+ SUBJECT + " = '" + subject + "' AND " + MONTH + " = '"
+ month + "' AND " + YEAR + " = '" + year + "'";
System.out.println("questions: " + whereClause);
Cursor cursor = db.query(true, "ANSWERS", new String[] { "MARKS" },
whereClause, null, null, null, "DEPARTMENT", null);
String list[] = new String[cursor.getCount()];
int i = 0;
if (cursor != null && cursor.getCount() > 0) {
for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor
.moveToNext()) {
list[i] = new String(cursor.getString(0));
i++;
}
}
return list;
}
Can anyone help me to resolve this issue?? Why getting only unique value,I have checked my json result also each row contains marks.

i got the solution for this,
Changed database query and method as following,
public List<Answer> getMarksList(String department, String subject,
String month_year) {
List<Answer> list = new ArrayList<Answer>();
String month = month_year.split("-")[0];
String year = month_year.split("-")[1];
try {
String sql1 = "select all marks from " + TABLE_NAME
+ " where department = '" + department
+ "' AND subject = '" + subject + "' AND month = '" + month
+ "' AND year = '" + year + "';";
SQLiteDatabase db1 = this.getWritableDatabase();
Cursor cursor = db1.rawQuery(sql1, null);
if (cursor.moveToFirst()) {
do {
Answer a = new Answer();
a.setMarks(cursor.getString(0));
list.add(a);
} while (cursor.moveToNext());
}
} catch (Exception e) {
}
return list;
}
using "all" in query is retrieving all records.

How to correctly handle select statements in SQLlite for android?

please help me in this issue. I am developing an application which works with a big database in android. The problem is that I need to do big procedures to get some specific info, but the application takes too long to respond and the screen goes black until solve the problem. I put an AsyncTask while it finds the response, but nothing seems to work.
This is a example method.

In order to process huge SQLite Database in Android, you have to use Custom Loaders. It improves the Database Performance.
To understand the concept of loader check this. To implement it, check this tutorial to set-up Custom loaders or you can find more about it in this Video.
Hope this works for you.

Thanks everyone! I solved my issue, only trying to make all the selects in one, because it consumes a lot of memory open and close a cursor.

Retrieving Data of last added event from android calendar

I want to retrive the data of last added event from android calendar. I am using this code to get last id.
public static long getNewEventId(ContentResolver cr, Uri cal_uri)
{
Uri local_uri = cal_uri;
if (cal_uri == null)
{
local_uri = Uri.parse("content://com.android.calendar/events");
}
Cursor cursor = cr.query(local_uri,
new String[] { "MAX(_id) as max_id" }, null, null, "_id");
cursor.moveToFirst();
long max_val = cursor.getLong(cursor.getColumnIndex("max_id"));
return max_val + 1;
}
And then I simply add an event using this code:
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", SelectedDate);
intent.putExtra("allDay", false);
intent.putExtra("rrule", "FsREQ=DAILY");
intent.putExtra("endTime", SelectedDate + 60 * 60 * 1000);
intent.putExtra("title", "Advance Scheduler Event");
startActivity(intent);
After this I simply retrieve the data of this event using this code:
public CalendarData EventDetails(int ID)
{
CalendarData temp = null;
// -------------------------------------------------------------------------------
ContentResolver cr = getContentResolver();
Cursor cursor_calendar;
if (Integer.parseInt(Build.VERSION.SDK) >= 8)

But I can't get the data of this event. I am not getting where is the problem. Please, help me to solve this.

use this code. its working in my aap

I used the following code to retrieve all the data on the Calendar which is:

SO all what you need as I guess is to adjust it little bit get data for last event.

ContentResolver cr = getContentResolver();
Uri caluri = CalendarContract.Events.CONTENT_URI;
Uri atteuri = CalendarContract.Attendees.CONTENT_URI;
Cursor cur1, cur2;
String all = null;
try
{
cur1 = cr.query(caluri
, new String[]{ Events.CALENDAR_ID, Events._ID, Events.TITLE, Events.DESCRIPTION, Events.DTSTART, Events.DTEND, Events.EVENT_LOCATION }
, null, null, null);
if (cur1 != null)
{
while (cur1.moveToNext())
{
String event_Title = cur1.getString(cur1.getColumnIndex(Events.TITLE));
String event_Desc = cur1.getString(cur1.getColumnIndexOrThrow(Events.DESCRIPTION));
Date event_Start = new Date(cur1.getLong(cur1.getColumnIndex(Events.DTSTART)));
Date event_end = new Date(cur1.getLong(cur1.getColumnIndex(Events.DTEND)));
String event_loc = cur1.getString(cur1.getColumnIndex(Events.EVENT_LOCATION));
String all_attendee = null;
String all_Emails = null;
String cal_ID = cur1.getString(cur1.getColumnIndex(Events.CALENDAR_ID));
String event_ID = cur1.getString(cur1.getColumnIndex(Events._ID));
cur2 = cr.query(atteuri, new String[]{ Attendees.ATTENDEE_NAME, Attendees.ATTENDEE_EMAIL }
, Attendees.EVENT_ID + "=" + event_ID, null, null);
if (cur2 != null)
{
while (cur2.moveToNext())
{
String attendee_name = cur2.getString(cur2.getColumnIndex(Attendees.ATTENDEE_NAME));
String attendee_Email = cur2.getString(cur2.getColumnIndex(Attendees.ATTENDEE_EMAIL));
all_attendee += "\n" + attendee_name;
all_Emails += "\n" + attendee_Email;
}
cur2.close();
}
all += "Event title: " + event_Title + "\n"
+ "Event Description: " + event_Desc + "\n"
+ "Event Start: " + event_Start + "\n" + "Events End: "
+ event_end + "\n" + "Event Location: " + event_loc
+ "\n" + "Attendees: " + "\n" + all_attendee + "\n"
+ "Emails: " + "\n" + all_Emails + "\n";
}
cur1.close();
}
System.out.println("My log--------" + all);

Android Application did not close cursor or database

Im running into an issue inserting items into my database. It really odd that the program will run through 4 rows and insert them fine, but on the 5th row it crashes and I got three reports of Application did not close cursor or database. In my code I am closing and reopening both the cursor and the database so I am really confused on how this is happening. Here is the code.
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case REQUEST_CODE_NEW:
if (resultCode == -1) {
Integer chapterId = data.getIntExtra("chapterId", -1);
Toast toast = Toast.makeText(this, "Selected Chapter: " + chapterId.toString(), Toast.LENGTH_LONG);
if (chapterId != -1) {
DbHelper db = new DbHelper(this);
for (int i = 0; i < questions.getTitle().size(); i++) {
db.insertQuestion(chapterId.toString(), questions.getTitle().get(i), questions.getAnswer().get(i), questions.getAr().get(i));
}
}
toast.show();
}
break;
}
}
Thats calling the database to be created through a dbhelper class. Here is the database helper
public void insertQuestion(String cat_id, String title, String answer, String article) {
db.execSQL("INSERT INTO " + QUESTION_TABLE_NAME + " (title,answer,article,picture) VALUES ('" + title + "','" + answer + "','" + article + "','none')");
String id = getQuestionId(title);
db.execSQL("INSERT INTO " + REL_TABLE_NAME + " (question_id, cat_id) VALUES (" + id + "," + cat_id + ")");
}
public String getQuestionId(String title) {
String id;
cursor = this.db.rawQuery("SELECT question_id FROM " + QUESTION_TABLE_NAME + " WHERE title = '" + title + "' LIMIT 1", null);
cursor.moveToFirst();
id = cursor.getString(0);
cursor.close();
db.close();
return id;
}
I put the cursor at the class level so I can try to manage it better, but still to no avail. Its still crashing after 4 queries.

Try this "fix":
DbHelper db = new DbHelper(this);
try{
for (int i = 0; i < questions.getTitle().size(); i++) {
db.insertQuestion(chapterId.toString(), questions.getTitle().get(i), questions.getAnswer().get(i), questions.getAr().get(i));
}
}catch(Exception e1){
android.util.Log.v("DbHelper Error","Crash: "+e1.getMessage(), e1);
}finally{
db.close();
}
