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.

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?
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?

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?
View 2 Replies View RelatedEverything is working fine, I can access the provider. The problem is that I want to create a demo version of my app and I want it to share the same content provider so when the user install the full version, the data is kept in sync. Also, it should be possible to install only the full or the demo version. Therefore, I have to include my content provider in both.Now, when I try to install both apps error message, obviously because both AndroidManifest declare the same content provider.Is there a way to tell in the Manifest that this content provider should be used only if it doesn't already exists ? Or another workaround ?A solution would be that the full version migrate the data from a demo content provider to the full version content provider, but I would rather avoid that.
View 1 Replies View RelatedI have a doubt regarding content provider.My doubt is I create a app1 that creates Content Provider and in second application(app2) i am using app1's content provider methods(like insert, update etc). It's working fine but i want to set some permissions in app1, so that if any other app wants to use that provider it must have to get this permissions(<uses- permissions) then only it should be able to use providers.

View 4 Replies View RelatedI am having trouble understanding content providers in Android. Do you use intents to call content providers as well as managed queries?
Also, an activity has an intent filter. The intent filter has a element which has a mimeType attribute. How does Android know which content provider this mimetype is referring to?
The tag in the manifest just lists an authority but not the full content_uri. Further, the content_uri is typically defined in an encapsulated class that seems to only consist of constants but no methods, so I don't see how that links over to the content provider class.
Is there a way to programmatically list all available content providers on a device? No real use case, I just thought it might be neat to see what apps I have installed on my phone that have exposed content providers.

View 2 Replies View RelatedI am trying to test my DB using Provider Test Case2<T>. I can see the test DB being created. As such I suppose, the tested content provider should use the test DB. But as soon as I try any calls against the Mock Content Resolver (or the one created with new Resolver With Content Provider From Sql), I get an Unsupported Operation Exception. This is documented for the Mock Content Resolver as normal behavior. As such I am a bit unsure on the purpose of the Provider Test Case2. How do you test your content providers?

View 2 Replies View Relatedinformation on direct access to GEARS geolocation functions from an Android application. To date, I have not found any. geolocation includes three Android-specific public Java classes, AndroidGpsLocationProvider, AndroidRadioLocationProvider, and AndroidWifiLocationProvider. The fact that they are Android-specific and that they are public lead me to conclude that I should be able to use these classes in my application. However, not surprisingly, when I try to access these classes, my application fails (see log below) because, among other things, I have no way to correctly identify nativeObject in the java classes. At the very least, I would like to understand the purpose of the three Android-specific public Java classes, and how we should use them.

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.
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?

View 4 Replies View RelatedI've just published an app to Google Play. It is an app that allows people (mostly tourists) in my area to easily find businesses around them. One functionality that my app offers is to make a phone call to these companies by tapping a button in the app, including emergency numbers.
Google Play says that the app requires "direct phone access, it can call phone numbers without your intervention, which can lead to a high phone bill, but not emergency numbers". This doesn't completely fit my intention.
My app would work just fine if it had to ask the user every time it wanted to make a call, and it doesn't call anything when no buttons are tapped, plus I DO want the app to be able to call emergency numbers (with the user's consent off course).
I've used XDA many times before, normally for specific questions on ARHD ROMs.
I work on a cruise ship and we're continually crossing time zones. Currently, to alter the time zone on my (rooted) HTC OneX, I need to pull down the notifications tray, select settings, scroll down and select date and time, then select time zone. I can't use the Auto function, as the network time on the ship (satellite) is only available over Wi-Fi, for which I have to pay an exorbitant rate.
I'm looking for an app that will allow me one-tap access to changing the time zone. 'Time Zone Widget Light' almost does the job, as a tap on the widget scrolls through pre-set time zones, but this only allows me to step forward, and sometimes I need to go backwards as well (sadly our ship itineraries refuse to follow pre-set time zones, although I'm working on it!)
Any app, or perhaps a toolkit that lets me drill down to sub-layers of the android settings menu and create a short-cut?
i have done SQLite database programming for Android, but i dont know anything about Content-Provider except this: "As i have referred Android Developer page , Android SDK explained about "Content-provider" as it is used to store and retrieve data." What is the exact difference between "Content-Provider" and "SQLite Database"?Which is best to store data, when ?
View 3 Replies View RelatedNot 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.
