Android :: Looking For A Provider
Jun 18, 2010
I am currently researching the android. As I travel to Europe quite often and live in the NYC area, I am hoping to get an unlocked android that I can use in Switzerland, Italy and the US.I would mostly be using the android for google search, browsing websites, google maps, chat and email and yahoo instant messenger but not facebook or any such sites.I am curious which android members of the forum would suggest and which carrier (at least in the US).

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.

I'd like to be able to read the system's SMS content provider. Basically I wanted to make an SMS messaging app, but it would only be useful if I could see past threads etc.It seems like there's a content provider for this, but I can't find documentation for it - anyone know where that is?

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)?

Is there a way to build a VPN 'provider' for Android? A way to add new VPN types to the existing VPN infrastructure? OpenVPN, for instance, though also things like pppoe might fit in this category.

I'm developing an android application that involves the detection of the users' location. What I would like to know is, how does this -> LocationManager.GPS_PROVIDER work?Does it uses the GPS system in the phone or does it uses the mobile company's area network location?Whenever I turn on the GPS system in my phone, the map would not load. It will only be able to detect & pinpoint the location when I deactivate it. I think the application is tapping into the GPRS or something.

I've created a home screen widget by extending the App Widget Provider. It works fine on all phones tested so far except Motorola's Droid 2 from Verizon. It's running Android 2.2. What I noticed is when my widget is first place onto a home screen it works for about +/- 15 seconds. Then I see the widget receives the action com.Motorola.blur.home.ACTION_WIDGET_ADDED and the widget stops responding? The buttons on the widget still show pressed or selected states but the widget code itself is no longer called?

I am creating a service client and the following lines give me error. I was wondering how to fix these... // I have put in the service client stuff below...
private CheckZone mBoundService; private ServiceConnection mConnection = new ServiceConnection() { public void onServiceConnected(ComponentName CheckZone, IBinder service) { // This is called when the connection with the service has been // established, giving us the service object we can use to // interact with the service. Because we have bound to a explicit // service that we know is running in our own process, we can // cast its IBinder to a concrete class and directly access it. mBoundService = ((CheckZone.LocalBinder)service).getService();
//This line complians about binding, and states that it can not be resolved. How do I fix this please? Toast.makeText(binding.this, "Connected to CheckZone", Toast.LENGTH_SHORT).show(); }

As we know, Google has hidden some APIs on newer SDKs, some of providers (i.e. Telephony provider) are hidden, we can only seen in source code, but we cannot use on the current SDK. So I wonder how we can use these providers. I know we integrate our own firmware, however, I wonder if we can solver this problem on the current SDK, so that my app can run on all public android system.

I would like to know the exact difference between Content provider and SQLiteDatabase. If we have to share our data among applications then we use Content provider, otherwise SQLiteDatabase. Is this is the ONLY difference, OR using Content Provider has something to do with performence?

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?

I have written the following content provider, but when I try to pull information from it into an array,I presume its something to do with my naming of the CONTENT_URI or something? I'm not quite sure how it works so could anyone explain a bit and spot what I have done wrong?

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).

I was wondering if anyone has any information on accessing the Gmail content provider. It doesn't seem to be officially supported in the API but it looks like people are able to do this regardless. 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.

I created SQLite base with 3 tables and custom ContentProvider. I had a crash on first call method query. I tried to get cursor from base via db.query(table, columns,...) it worked correctly.
The exception is android.database.sqlite.SQLiteException: no such column: modified: , while compiling: SELECT items._id, items.name FROM items ORDER BY modified ASC
The method is below:

As I understand it, I have three location providers to choose from: GPS, Network and Passive.
I would like to obtain my location by detecting the Wi-Fi network I'm connected to, I believe both Cell Triangulation and Wi-Fi location determination is covered under the Network provider.
However, despite being connected to a Wi-Fi access point, my program always seems to use cell triangulation rather than Wi-Fi to determine my location (assumed based on the huge inaccuracy of the returned coordinates).
It doesn't look like there's any way to force the use of Wi-Fi only? How does Android decide when to use Wi-Fi over cell triangulation?
