I haven't found any solution for this problem in the bunch of
questions and reference I've searched.
So here is.
I'm trying to query the data from the CallLog and insert in DB. For
that, I've created a COntentObserver as inner class in a Service, and
inside onChange() method, I call my method that goes to the specified
URI and query the data that has changed.
But, lets say, I received a call, so the observer was notified. So, my
method goes to the call log content provider, query and insert, but it
is inserting two, three times the same register.
And the funny is that I have another service implemented identically
like this one, but, it doesnt happen.
Here is the code of my service.
public class RatedCallsService extends Service
private Handler handler = new Handler();
private SQLiteDatabase db;
private OpenHelper helper;
private String theDate;
private String theMonth_;
private String theYear_;
private String theDay_;
public static boolean servReg = false;
class RatedCallsContentObserver extends ContentObserver {
public RatedCallsContentObserver(Handler h) {
super(h);
//helper = new OpenHelper(getApplicationContext());
//db = helper.getWritableDatabase();
}
@Override
public boolean deliverSelfNotifications() {
return true;
}
@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
Log.i(LOG_TAG, "Inside on Change. selfChange " +
selfChange);
searchInsert();
}
}
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
servReg = true;
db = DataHandlerDB.createDB(this);
registerContentObserver();
}
@Override
public void onDestroy() {
super.onDestroy();
db.close();
this.getApplicationContext().getContentResolver().unregisterContentObserver(new
RatedCallsContentObserver(handler));
}
private void searchInsert() {
Cursor cursor = getContentResolver().query(
android.provider.CallLog.Calls.CONTENT_URI, null, null,
null,
android.provider.CallLog.Calls.DATE + " DESC ");
if (cursor.moveToFirst()) {
int numberColumnId = cursor
.getColumnIndex(android.provider.CallLog.Calls.NUMBER);
int durationId = cursor
.getColumnIndex(android.provider.CallLog.Calls.DURATION);
int contactNameId = cursor
.getColumnIndex(android.provider.CallLog.Calls.CACHED_NAME);
int numTypeId = cursor
.getColumnIndex(android.provider.CallLog.Calls.CACHED_NUMBER_TYPE);
int callTypeId = cursor
.getColumnIndex(android.provider.CallLog.Calls.TYPE);
Date dt = new Date();
int hours = dt.getHours();
int minutes = dt.getMinutes();
int seconds = dt.getSeconds();
String currTime = hours + ":" + minutes + ":" + seconds;
SimpleDateFormat dateFormat = new SimpleDateFormat("M/d/
yyyy");
Date date = new Date();
cursor.moveToFirst();
String contactNumber = cursor.getString(numberColumnId);
String contactName = (null ==
cursor.getString(contactNameId) ? ""
: cursor.getString(contactNameId));
String duration = cursor.getString(durationId);
String numType = cursor.getString(numTypeId);
String callType = cursor.getString(callTypeId);
seconds = Integer.parseInt(duration);
theDate = dateFormat.format(date);
if (theDate.length() == 9) {
theMonth_ = theDate.substring(0, 1);
theDay_ = theDate.substring(2, 4);
theYear_ = theDate.substring(5, 9);
} else if (theDate.length() == 10) {
theMonth_ = theDate.substring(0, 2);
theDay_ = theDate.substring(3, 4);
theYear_ = theDate.substring(6, 10);
} else if (theDate.length() == 8) {
theMonth_ = theDate.substring(0, 1);
theDay_ = theDate.substring(2, 3);
theYear_ = theDate.substring(4, 8);
}
ContentValues values = new ContentValues();
ContentValues values2 = new ContentValues();
values.put("contact_id", 1);
values.put("contact_name", contactName);
values.put("number_type", numType);
values.put("contact_number", contactNumber);
values.put("duration", Utilities.convertTime(seconds));
values.put("date", dateFormat.format(date));
values.put("current_time", currTime);
values.put("cont", 1);
values.put("type", callType);
values2.put("month",
Utilities.monthName(Integer.parseInt(theMonth_)));
values2.put("duration", Utilities.convertTime(seconds));
values2.put("year", theYear_);
values2.put("month_num", Integer.parseInt(theMonth_));
if (!db.isOpen()) {
db = getApplicationContext()
.openOrCreateDatabase(
"/data/data/com.project.myapp/databases/
myDb.db",
SQLiteDatabase.OPEN_READWRITE, null);
}
if (duration != "") {
if (Integer.parseInt(duration) != 0) {
String existingMonthDuration = DataHandlerDB
.selectMonthsDuration(theMonth_, theYear_,
this);
Integer newMonthDuration;
if (existingMonthDuration != "") {
newMonthDuration = Integer
.parseInt(existingMonthDuration)
+
Integer.parseInt(duration);
values2.put("duration",
Utilities.convertTime(newMonthDuration));
db.update(DataHandlerDB.TABLE_NAME_3, values2,
"year = ?", new String[] { theYear_ });
} else {
db.insert(DataHandlerDB.TABLE_NAME_3, null,
values2);
}
db.insert(DataHandlerDB.TABLE_NAME_2, null, values);
}
}
cursor.close();
}
}
public void registerContentObserver() {
this.getApplicationContext()
.getContentResolver()
.registerContentObserver(
android.provider.CallLog.Calls.CONTENT_URI, false,
new RatedCallsContentObserver(handler));
}
}
I've tried everything. unregistering the observer, etc. but nothing.
Thanks in advance.
