I am able to get a generic notification "that there was a change to the contacts DB", but I want to know the specific record that was inserted, updated, or deleted. Following is the code that gets registered and gets the onChange notification. Unfortunately, it is not specific which makes my processing exhaustive and inefficient.
Here is the code stub:
if ((mNativeContactsObserver == null) && (mHandler == null)) {
mHandler = new Handler(this.getMainLooper()) {
};
mNativeContactsObserver = new ContentObserver(mHandler) {
@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
Bundle data = null;
Message message = mHandler.obtainMessage();
if (message != null) {
data = message.getData();
if (data != null) {
Logs.d(TAG, "Message = [" + message.toString() + "] data=[" + data.toString() + "]");
Logs.d(TAG, "Contents = [" + message.describeContents() + "]");
}
}
if (!selfChange) {
final Account accountListen = MySyncAdapter.lookupAccount(TAG, getApplicationContext(), getUserProfile().getAccountId(), AUTHORITY_MY_SYNC);
Logs.d(TAG, "onChange!? account: " + accountListen.name);
if (!ContentResolver.isSyncPending(account, ContactsContract.AUTHORITY)
&& (!ContentResolver.isSyncActive(account, ContactsContract.AUTHORITY))) {
Bundle extras = new Bundle();
extras.putInt(MySyncAdapter.EXTRA_SYNC_TYPE, MySyncAdapter.REQUEST_SYNC_NATIVE_CHANGED);
ContentResolver.requestSync(accountListen, ContactsContract.AUTHORITY, extras);
} else {
Logs.w(TAG, "There is a pending sync. This request is ignored.");
}
}
}
};
}
Uri uriContactsListen = ContactsContract.Contacts.CONTENT_URI.buildUpon().appendEncodedPath("#").build();
Logs.i(TAG, "Register listening for native contacts changes. [" + uriContactsListen + "]");
cr.registerContentObserver(uriContactsListen, true, mNativeContactsObserver);
Finally at least i am able to detect is this Update/Delete/Insert look at my OnChange
method as below
@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
Log.e("ContactChangeObserver", "onChange");
// 0 Update , 1 Delete , 2 Added
// Get count from phone contacts
final int currentCount = contactDBOperaion.getContactsCountFromPhone();
// Get count from your sqlite database
int mContactCount= DbContacts.getInstance().getContactsCount();
if (currentCount < mContactCount) {
// DELETE HAPPEN.
Log.e("Status", "Deletion");
contactDBOperaion.SyncContacts(1);
} else if (currentCount == mContactCount) {
// UPDATE HAPPEN.
contactDBOperaion.SyncContacts(0);
} else {
// INSERT HAPPEN.
Log.e("Status", "Insertion");
contactDBOperaion.SyncContacts(2);
}
}
When Update occurred i update all contacts
When Insert occurred i am inserting newly added row , after checking isExist in existing database
When Delete occurred not found solution yet
