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 Providers / Database Initialisation

Feb 18, 2009

I have a plethora of data which is currently stored in 1000 different very small text files, I want to store this data in an SQ Lite database as I feel that this will be more space efficient and hopefully time efficient as I presume a database query is faster than opening and parsing a text file (please stop me now if this isn't the case!). The data does not need to be available to other applications and will be used internally only. My first question is whether or not to create a content provider anyway, is there any benefit to this? My second question is where to initialize the database, is it possible to ship an application with a database included already populated? Do I have to populate it in the on Create method of the SQ Lite Open Helper subclass? If I have to include the 1000 text files and read, parse and insert the data at inst all time I have a feeling this would be slow. Is it possible for me to populate the database now, dump it to a single file and then bulk insert from the file in the on Create method?

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?

AsyncTask Force Close Errors / HTTP Request To MySQL Database

Aug 22, 2012

I'm trying to connect my app to a MySQL database to retrieve data. Obviously I have to do this in a new thread hence why I chose AsyncTask, something I'm new to.

I have included Toasts to tell me if there are problems when trying to carry out any part of it. However these toasts are not showing on the UI thread. I tested this out by turning off the server my SQL database is on so that it could trip the first toast. It didn't show it though and instead it gave me a force close error. When my server is running I have no issues and although I haven't coded the bit to retrieve data yet the code below does connect to my database and at least lets me view the page "CurrentSeasonDrivers".

Here is my code and the logcat showing the errors below that:

packageĀ com.android.history;
importĀ java.io.BufferedReader;
importĀ java.io.InputStream;
importĀ java.io.InputStreamReader;
importĀ java.util.ArrayList;
[code]....

All I want it to do is show a toast if the application cannot connect to the server instead of force closing.

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 :: 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 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 :: Can't Store Hash On Database / Content In SharedPreferences Secured On Droid Device?

Sep 14, 2009

We want to store credentials for a user to a web service so the user doesn't have to repeatedly login, but we're concerned about security. We can't store a hash on the database, but we could probably use JCE encryption locally.

Is the content in SharedPreferences secured on the Android device?

Android :: Switching Content Providers For Same Content URI

Aug 12, 2009

This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

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.
