Android :: ContentProvider Queries - Contacts And The SDK Docs
May 15, 2009
A couple of questions. First thing I was wondering is where to log bugs in the docs. The ContentProvider query() docs are missing selectionArgs in the example code. It also uses the deprecated addId instead of ContentUris.withAppendedId().
With regards to the selection options - how exactly can these handle? I've seen a couple of places where a something + "='" + somevalue "'" is used, but I'm specifically wondering if it can handle IN clauses or if there's some form of or statement I can use to check for a variety of values in a particular column rather than just the one.
Last question is about the Contacts PERSON_ID and how long-lived that is. It is guaranteed to never change (though may be removed obviously). Well not truly guaranteed but will only cycle after it runs out of unused integers. Or may they change value as contacts are removed?

I want to add an extra field to the phonebook on android. The field contains a new contact method and when clicked it should start my own application/intent. I have created my own content provider that stores the information. I want to add this contentProvider to the phonebook in the same way organizations and email are added to the phone book. So how do i do this? I tried adding a new contact method but the field KIND needs an integer input which seems to be predefined to some specific methods (EMAIL, IM, ADDRESS etc)
So do i need to add a new type of KIND or can I link my contentProvider to the phone book so that it shows up as an extra field in the phone book?

I am new Android user and very happy with HTC Desire. However, frustrated that common Office apps not able to edit e-mailed docs, or send edited docs. Have looked at Quick Office; Documents To Go; & Office Suite Pro. Anybody know of a suitable app - this seems like a significant limitation to me. Adam

Can anyone point me to a good example where a AsyncTask queries a local SQLite database and then updates the UI successfully. I have a database which I query using doInBackground... create a new custom SimpleCursorAdapter (overriding onViewBind), return the adapter (SimpleCursorAdapter), then in postExecute() create ListView adapter which is set to the the SimpleCursorAdapter, that was returned, then I set the listview adapter using SetAdapter(adapter);...
For some reason I throw an exception on fillWindow.java:200....

I start a long-running SQL SELECT query and, before it finishes, wish to make a short-running SQL SELECT query. Both queries are on the same tables. The whole database can be considered read-only. My initial tests show that the short-running query only actually starts when the long-running query has finished.

I was monitoring the traffic on Eclair 2.1 and noticed periodic DNS queries to "android.clients.google.com" after launching IM/Email/ Browser even though the phone was idle and I was not doing anything. why Android generates these periodic queries to "android.clients.google.com"? Is there a specific service generating these queries?

There is a user input then on submit pass the search keywords to the db server and return the results (the db server has to be external by the way). Could i pass the search query to server side (php) and get the php script to execute the queries and return the scripts output?

I'm just using the build in email app for my hotmail, gmail, work mail etc. However It keeps bringing up old messages that I leave in my inbox. How can I get it to not keep displaying these? Or better yet is there a killer app out there that does email/contacts better? I hate having to use the whole gmail thing.

Has anyone other than me needed to make consecutive queries to a sqlitedatabase? My application works sometimes but other times (about 98% of the time), the app will crash. What I'm doing is using the sqlitedatabase.query(..) to return a cursor which I parse, I make multiple successive queries to the database and parse different recordsets/cursors.
My question would be does a sqlitedatabase need to recover or clean up after a .query is issued?

have an activity handling search (ACTIVITY_1), which works perfectly when I use the search (via SEARCH button on the phone) within/from this activity. However, when I use search from another activity (ACTIVITY_2..x) by implementing onNewIntent and forward the query string to my Search_Activity.class (ACTIVITY_1) it always pauses ACTIVITY_2 first and then goes to onCreate() of ACTIVITY_2..................

I have some queries:
1- I have Desire with Froyo. So, technically whenever I install an app, I should be given an option to install it on SD card. But so far, haven't seen it yet, consequently today I got a message that phone memory is running low. So, please help me out.
2- Secondly, last night due to some reason I opened navigation first time and there came two pop-ups asking me for some settings. I ticked them and then a satellite logo appeared on top bar. Does it consume a lot of battery?
3- So far I have set many applications on automatic updates but I have observed that I have to always update them manually. They don't get updated automatically.

Well I bought my Galaxy here in India yesterday, and you all and this forum has been a major source of info to make up my mind.
Well I've bee browsing this forum trying to understand all that I need to know for the past two days before I could muster the courage to ask a couple of questions.
1) My Galaxy is on Firmware II3, is it worth upgrading to IK5 ?
2) When I upgrade, does everything, contact, apps etc, get wiped of from the device or do they remain as they are ?
3) Is there a way I can take a complete backup of my contacts, apps etc and restore them after a firmware update ?
My phone has not been rooted yet and I plan to use ODIN for updating the firmware.

All the example codes, tutorials or video I see, there is always one ContentProvider per SQL Table with the SQLiteOpenHelper extension defined as a private static class... Is it some sort of standard design...to have one ContentProvider per SQL Table? Or I can define one generic ContentProvider and use its instance for ever update? Is there some issue with that? Could anyone please help as my application has like 5-6 tables.

Maybe it's an easy question, but I've tried to understand why all the content providers seem not to close the DB that they use. In the NotePadProvider example (in other providers is similar), it's used a Helper to manage the DB (that extends of SQLiteOpenHelper).
This helper has a method to close the DB (http://developer.android.com/ reference/android/database/sqlite/SQLiteOpenHelper.html#close%28%29), but in all the providers that I have seen (even in the example), this method is never used.
For example, in the query method of the NotPadProvider we use the helper to open a DB
CODE:...........
The mOpenHelper is create in the "onCreate()" method, but there is no reference to a mOpenHelper.close() in all the provider (maybe because there is no "close()" method in ContentProvider).
Do we need to close the SQLiteOpenHelper object? When we use it inside a ContentProvider, where is the right place to close it?

I have a custom class, which represents my data-structure. This custom class is in a normal Java-library, which is included in both projects. I have one Project with a ContentProvider which provides this data to Activities of other Projects. And an other Project with an Activity, where I want to handle this data in objects of this custom class.
How can I get this data to the Activity? The Cursor [1] only supports primitive Types.

My wife has been playing with her new phone and needs some help with contact management.1, How can she keep the telephone contacts separated from her facebook contacts. Currently when she presses the phone button from her home page it seems to show all contacts. However when she goes to HTC People it is set to only show phone contacts not facebook contacts. 2, When you have facebook contacts how do you delete them? Do you have to remove them as a friend?I've changed my phone number on my facebook profile but it still shows on my wife's desire as my old number. She's tried removing me as a friend and re-adding me and it's still wrong.

I went through many threads regarding XT530. links are URL>....the first thread is said to be root XT530 (2.3.5 based) but the title goes for XT316(2.3.4). So i am a bit worried if thats alright or i got wrongly redirected over there. Moreover, the links for the files weren't working, so i need links for the files needed (like Google GMS pack).
the second thread says it will root the current android version, but i need to ask if that would install Google GMS services automatically or i need to download that pack externally.
1. I got just 19mb to 25mb as my internal memory constantly. i mean, i dont think i would get more than 35mb of internal memory even if i remove all apps installed. is it normal?
2. would i be able to shift apps to SD card after rooting?
3. can i overclock my phone? and if yes, what is the maximum limit?

I have looking for something and found these inconsistencies in the online documentation
Now when I try to find the 'notifyWithText' api, I could not find it.
Another example is IntentReciever. I just want to know is this class exists? As I found code in this forum itself using IntentReciever, but I cant find this class in the doc.
And why standard intents like action android:name="android.provider.Telephony.SMS_RECEIVED are not documented?
