I am in desperate need of good tutorials on Content Providers in Android. I have been searching in the web for the tutorials but none could give me a clear idea on how content providers work. I'll be grateful if anyone can provide me with sample codes of the projects that implement content providers...

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 1 Replies View RelatedI 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?

View 2 Replies View RelatedJust 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.
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 RelatedI'm attempting to make a custom Content Provider so that more than one application (activity?) has access to it. I have several questions about how to do this, How do I declare in the code that it is a Content Provider? How do other applications (activities?) use or import the Content Provider?
View 2 Replies View RelatedAs I am one who cannot find any decent Android-based OpenGL ES references, I have decided to start one. You can check it out at http://www.vincepascuzzi.com. As I am not a seasoned GL programmer, any and all comments and/or questions are greatly appreciated!
My mission is to first create an OpenGL version of an application on Mac OS X, and then port to Android. Once the port is done, I go through each program, step-by-step, and contrast and compare how the port was done. I also explicitly point out any and all differences between the two, subtle or obvious.
I'm just looking at the Android's native IM app and wondering if it's possible to create new providers? I know other people have written seperate IM clients but it'd be great to add to list in the native IM app.
The 3 I'd like to work on is Facebook, MySpaceIM, Skype.
Do you know a good tutorial about OpenGL ES 2.0? I'm going to use it with Android and C++.

View 1 Replies View RelatedMy application requires current location of the user. For this I have implemented the code and I am able to get the current location. The code tries to get the best provider first and then fetches location information. The problem is that the current location is returned from NETWORK_PROVIDER if GPS_PROVIDER is disabled. If both NETWORK_PROVIDER and GPS_PROVIDER are enabled then the best provider will be GPS_PROVIDER and this takes too much time to get the current location.
So, is it alright if we set the location provider as NETWORK_PROVIDER only so that it will not matter whether GPS_PROVIDER is enabled or not.
I want my app to be able to retrieve a fine location, but also to be able to get it's location as quick as possible. What I'm trying to implement is something like the way it works in maps, i.e. it gets a coarse location via network and then refines that location using GPS.
If I set the criteria to ACCUARCY_FINE it automatically tries to use GPS to get the location. The problem is that if a user is indoors then this may take several minutes, if it finds it at all. Is there an easy way to tell the manager to use network provider and then GPS, or will I have to do this myself? If so what's the best way to go about this? Will I need to thread it in some way?
I'm sorry if these questions have been answered already. I've found various location examples but none that seem to do what I'm asking.
I'm trying to get a list of the available cellular network providers. Unfortunately i can't find any service or class that might help me out :( Does anyone have an idea on how to manage this? It has to be possible since you can see the list when you go to the settings on your Android device..

What tutorials and libraries are available which can help beginners to develop 2D and 3D games on Android using OpenGL-ES? I'm looking for tutorials which can help me learn OpenGL-ES, and I'm looking for OpenGL-ES libraries which can make life easier for beginners in OpenGL-ES.
Since Android is still small, I guess it may be help-full to read iPhone OpenGL-ES tutorials as well, as I suppose the OpenGL-ES functionality is much the same.
I have found the following useful information which I would have liked to share:
Android tutorials: DroidNova: Basic tutorial covering polygons, no textures anddev forum with some tutorials
Other Android OpenGL-ES information: Google IO lecture regarding games, not much OpenGLES The The Khronos Reference Manual is also relevant to have, but its not exactly the best place to start.
iPhone OpenGL-ES tutorials (where the OpenGl-ES information is probably useful): http://web.me.com/smaurice/AppleCoder/iPhone_OpenGL/Archive.html
[url]
As for libraries which a beginner might use to get a simpler hands-on experience with OpenGL-ES, I have only found Rokon, which is recently started, thus has many holes and bugs. And it's gnuGPL licensed (at the moment) which means it cannot be used, if we wish to sell our games.
I follow the instructions exactly on this page (and some of the other tutorials) but they always seem to be missing some key information as they dont work out of the box
I added a bunch of packages that seemed like were missing, but now I'm stuck.

It's frustrating knowing exactly what you want to do and no idea how to do it. Something that uses basic language and explains each line in detail to help a person remember how to do it later. Any suggestions would be great.
View 1 Replies View RelatedHow do I enable/disable GPS and Wifi providers? I check to see if they are enabled by using this code:
locationManager.isProviderEnabled("gps") locationManager.isProviderEnabled("network")
If both are false, I'd like to turn enable the GPS provider and/or the Network provider so that the above checks would return true. Is this possible? If so, what permissions does it require?
I'm considering switching from T-mobile to verizon for this phone. I was this close to getting the motocliq but this device seems to be much better as long as the keyboard is functional since I'm not even a social networker. How many of you are considering switching carriers for this phone and do you think its worth it?
Is it true there's a 30 day buyer's remorse period on verizon so if I just get it and don't like it for whatever reason, I'm safe to remain with t-mobile and not be committed?
