You can delete with content resolver by URI or by passing some parameters to the where parameter.
How do you make the parameters to be SQL Injection Safe?
Is it possible to use Prepared Statements with ContentResolver?
act.getContentResolver().delete(myuriwithid,null,null);
act.getContentResolver().delete(mybaseuri," name = '"+this.name"'",null);

Last night I donated and am just waiting for the paid version now, but I have a couple of questions:
1. What exactly is "freezing" an app? Will it remove the app from the app drawer? Will it just prevent it from running?
2. Can I use Titanium backup to delete apps that are safe for delete like amazon.mp3, etc?
3. If I "freeze" an app like backup assistant will it still be on the phone so that it doesn't brick if I do a reset?
4. Can I delete or freeze things like crap ringtones so they don't show up when I am setting a ringtone?
I am thinking to create a static method to return a reference to the application instance. I am not sure if it is safe to assume there is only one instance of the Application in one application. Apparently, the Application class in Android SDK doesn't provide such method to return the instance reference. So I suspect there must be a reason?

I want to be able to query a ContentProvider from a Service, so my understanding is I will need to use a ContentResolver. What I can't seem to find is how do I get a Context that I can use to create the ContentResolver with?
View 3 Replies View Relatedfor some reason i would be executing a raw query or at least a query with group by clause and having clause to the table calls from database contacts.db.Adding the group by clause and the having clause to the where clause will result in exception.Open the database(/data/ data/ com.android.providers.contacts/databases/contacts.db) with SQLiteDatabase. open Database()also throws an exeception.

Why the contactsCursor is null? The number is in the contacts. Is there any mistakks in the query?
I'm trying this code and it's getting stopped in the getContentResolver statement....
CODE:.........
The goal: refresh database from XML data
The process:
Start transaction
Delete all existing rows from the tables
Per each main element of parsed XML insert row into main table and get PK
Per each child of the main element insert record into 2nd table providing FK from the previous step
Commit transaction
Pretty standard stuff as far as db operations. The problem is that CRUD operations are not done within ContentProvider but rather using ContentResolver so the insert for example looks like resolver.insert(CONTENT_URI, contentValues). The ContentResolver API doesn't seem to have anything pertained to transaction and I cannot use bulkInsert since I'm inserting in 2 tables intermittently (plus I want to have delete inside the transaction as well).
I was thinking of registering my customized ContentProvider as listener by using registerContentObserver but since ContentResolver#acquireProvider methods are hidden how do I obtain the right reference?
What would be a sensible way to add DISTINCT and/or GROUPBY to ContentResolver- based queries. Right now I have to create custom URI for each special case. Is there a better way?
(I still program for 1.5 as lowest common denominator)
I am wondering if Android's ContentResolver supports using SQL functions over the columns when you query a ContentProvider. Such as SQLite3 date functions, to get a specific date format, or datediff?
View 1 Replies View RelatedI know that after downloading an mp3 from your app you need to add it to the ContentResolver to see it on the music player. I am doing it with the following code...
My issue is that I am willing to avoid setting DISPLAY_NAME, ARTIST, ALBUM, TITLE by hand.
Is there a way to tell Android to do it from the file? I've already used just values.put(Media.DATA, pathToFile); but it's not adding it to the player.
Is there a way to force the thread that scans the sd for music?

In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

View 4 Replies View RelatedHow to add contacts in Android 2.2. Please help as I am not able to make it. I am adding contacts but it is not visible.
View 2 Replies View RelatedI get records from the system by quering a ContentResolver. I maintain the order of the items in the database. So I want to display the items in the order taken from my database.
How do I merge these two informations?
I am looking after an alternative way now. As what I ideally want is:
Get order of contacts by a custom order held in my database (this involves joining CR with my DB cursor, and doing an order by, later seams it's not possible with CursorJoiner) but there is more, if the join is not unique I want to sort by contact's name as last measure
Which is impossible using Cursor and Joiners, because of the missing feature of order bys, also I need to return a Cursor, as I will be using the in an ExpandableList
Also this translated to TSQL it would look like
select * from contactsdata
left join category on contactsdata.catid=category.id
order by category.pos asc, contact.display_name asc
So I am looking now after an alternative. I have in mind to load in a temporary DB table all data from CR, then do the query on the temporary table where I can join tables and do order bys? How does this sound to you?

View 1 Replies View RelatedI use a single static class in my code that defines a static field which I'm reusing between Activity onStop/onStart invocations. Here's a scenario:
User clicks on "Authorize" button (static data is initialized) Activity is stopped and web browser is called
Browser executes callback and Activity is restored (static data is reused)
At least one of my users reports the failure at step 3 which I cannot reproduce but which looks like reset of static data.
This procedure can clear a large number of problems and should be tried before a Hard Reset.
1.) Turn phone off remove battery WAIT for at least two minutes.
2.) Power On Phone while Holding MENU key Until ALL actions finish from Powering on phone At the bottom left corner of the display in transparent text will be the words "Safe Mode"
3.) Power off phone again battery out wait two minutes
4.) do a normal power on
i just got the 2.1 update this morning and was cleaning up a few unused apps and i came across launcher. I couldn't believe I still had it on here (been using sweeterhome) and so i remembered i had to go into safe mode to remove it. Tried to get into safe mode no luck. thought, ok, i'm missing a step or something. looked up the directions to make sure i was doing each step correctly and still nothing! i've held the power button and the menu button (keyboard) down at the same time until i saw the eye, until after the haptic then major vibration. i tried holding the menu and power, then releasing the power while still holding menu until both things i just stated and still nothing! what is happening is after I hold the buttons until after the vibration one of two things happens,it will go back to the screen that spells out droid then the eye or it will load normally, no safe mode on the screen. i read somewhere doing a google search that someone else had this same experience and asked for help and no one replied.
