Android : Content Provider Vs Direct Database Access - Transaction Management

Aug 7, 2010

I understand, at least on paper, the basic difference between the Content Provider and just directly accessing the SQLiteDatabase. I have a functioning prototype for my application, and currently it is just directly hitting the database. I don't really have any experience using the Content Provider pattern, but I have found out that I will need to share some data with another application.

I will only be sharing about 2 out of a dozen or so tables, so I was wondering if I should be just completely redoing the data layer to follow the Content Provider pattern, or just expose only those tables via a Content Provider for the sake of the other application and still directly access the database in the primary application.

One of the issues I ran into with my prototype was that I have some fairly complex transactions, and the code I wrote to get that working is not designed particularly well and isn't reusable at all. As I add more functionality to this app, I'm going to need a better designed data access layer, before I set off writing my own, does anyone know of any good resources with design patterns for this type of thing already? Also, if I need to go the Content Provider route, am I going to have solid control over the database transactions?

Android :: Direct Database Access Instead Of Content Providers

Sep 2, 2010

Just found out that I don't need content providers if I don't need to share data with other applications. But since the examples I've seen all use content providers, I'm not sure how to proceed without them and populate activities with data derived from accessing my application's database directly.

Android : Content Provider Or Database

Nov 22, 2010

Since I've seen a presentation from Google IO I'm a bit confused in the question, if it's better to use content providers or databases. Or it makes no difference if I don't want to share any data with other applications.

If I've understood it right, content providers based on SQLite DBs and it's also possible that content of them is only accessable for my application.

Android :: Content Provider Database Leak

Sep 4, 2009

I am writing a content provider for this application and in my content provider I am opening a database connection, running a query and returning the cursor of results to the calling program. If I close this database connection in the provider, the cursor has no results. If I leave it open, I get "leak found" errors in my DDMS log. What am I missing here? What's the clean, proper way to return a cursor of database results?

Android :: Possible To Write Custom Content Provider For Existing System Database?

Dec 9, 2009

Not sure of the absolute utility of this but seems as though it should be possible and useful. Can you extend ContentProvider to provide URIs representing new queries (i.e., joins across multiple tables not specified by existing URIs) for an existing system database? The alternative seems to be that I need to write a series of cursor queries then join them -- seems like a lot of unnecessary code duplication.

I have been trying this for the contacts database as an exercise, but no love so far. The crux seems to be that I cannot open a database in another package during the setup phase. Am I just completely out in left field here? It's possible as I am new to both Java and Android.

Android : Content Provider - No Link Between Content Provider And Its CONTENT_URI Declared In Another Class

Mar 1, 2010

I am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.

I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.

Android :: Apply Access Restriction On Content Provider

Sep 14, 2010

I found that if I want to use the searchable options using the search key I have to create a content provider. Content provider is used to share data across applications.

But I do not want to allow access to my content provider (as well as my data) except/outside my own application. I want to use it only for search suggestion. Because my app data is kind of restricted.

Is there any way to implement local search without content provider? OR is is possible to apply restriction so that except my own app no other app can use my content provider?

Change Content Management System

Nov 20, 2012

I've recently started programming my first android app in eclipse using java and xml and I'm relatively new to both languages.

My App will contain mostly static information for students in university which I plan to simply save as text in the xml itself but the clients wish to have a few pages on the app with content that they will be able to change regularly without having to look at or understand any code.

Basically what I'm looking to do is have a basic content management system that can only be accessed by the client and they can use it easily enough to change the content of those specific pages.

Android :: Content Provider Without SQL

Jun 4, 2010

my android application is handling a large database of bus passage time and we would like to allow others application to be able to display certains bus passage time. We would like to use a content provider to do that. Most example seems to be about using an SQL database, but we use some custom text file. I was wondering what would be the best way to do that. I was thinking I could use a Content Provider and implement the Cursor interface on a custom object that I would manually fill with my text data. Would this be possible ? Anyone have a better idea (excluding changing to SQL lite of course)?

Android :: Caching Content Provider

Feb 2, 2009

I am performing hundreds of calls to a single content provider to perform various insertions, updates and deletions. After profiling my application, I have noticed that the ContentResolver class takes approx. 30ms to retrieve the corresponding content provider object for each call. Is there anyway to retrieve a reference to the content provider rather then going through the ContentResolver every time?

Android :: Stopping Content Provider

Oct 21, 2009

The Content Provider starts when the first applicable URI is resolved. This will make the ContentProvider run forever and there doesn't seem to be a way to stop it (such as due to inactivity etc).It would be nice if Content Provider would stop after some time so that the memory usage is reduced (An enclosing process, doesn't need to be alive if the Content Provider is not needed anymore).

See the SlideScreen app which notifies you of new e-mail and even shows you info (sender, title).It would be great to know how this is accomplished, for example we could create a home screen widget that shows you your last few e- mails, etc.
