At the application level, my data is of the form.
* Event
* Contact List
* Contact
* Name
* Email
* Contact
* Name
* Email
The number of contacts is not predefined. Any thoughts on how to push this into a ContentProvider in one go? I basically dont want my application to worry about the hierarchy and bulk insert or something, I want to hand this responsibility over to the ContentProvider.

View 2 Replies View RelatedHow to retrieve data from two tables via the ContentProvider way? I.E. the database of Calendar application, include many tables including Events and Deleted, and some others. I want to retrive records in Events table, whose _sync_id field is also in Deleted table. Usually, we write a SQL sentence like: select (all fields in Events) from Events as e, Deleted as d where e._sync_id = d._sync_id or select * rom Events as e where e._sync_id in select _sync_id from Deleted etc. But, how can I accomplish it in the ContentProvider way? I saw ContentProvider.query take a Uri as the first parameter, but pity that I don't know how to build one that could fulfill my purpose.
View 2 Replies View RelatedI have some questions about how the ContentProvider works behind the scenes.
1. The ContentProvider class is registered in the kernel when the application is installed and then what? Or how do the other applications exactly manage to access the application data?
2. When is actually onCreate called? The documentation is pretty vague...
3. What happens if two applications register the same provider class? (I have more applications that must communicate between eachother. The content provider must be registered, of course, along with the first application installed on the system. The problem here is that I don't know which one will be, so I want to deliver the ContentProvider with all the applications)
Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.
In a layout (linear, vertical) hierarchy I've got several view and one of them is a WebView. Is there a way to let the webview resize itself, to match it's content size? By the way the space left vary from one device to another (emulator vs Milestone vs Hero)..
View 1 Replies View RelatedI am working on an application that requires an approximate position of the user, so basically i am fine with any relatively recent location data i can get. However I can't seem to get things right using mock location data and would therefore appreciate your help. The method i'm having tries to set mock location data for the gps provider and tries to later retrievie it BUT: locationManager.setTestProviderEnabled("gps", true); seems to fail because i do not get any active location provider from the location manager. When I tried using a mock location provider with addTestProvider and give it my mock location, the LocationManager returns me this mock provider with getProviders(true) but then getLastKnownLocation returns null instead of the provided mock location.
View 4 Replies View RelatedI have a widget that supposed to call an Activity of the main app when the user clicks on widget body. My setup works for a single widget instance but for a second instance of the same widget the PendingIntent gets reused and as result the vital information that I'm sending as extra gets overwritten for the 1st instance. So I figured that I should pass widget ID as Intent data however as soon as I add Intent#setData I would see in the log that 2 separate Intents are appropriately fired but the Activity fails to pick it up so basically Activity will not come up and nothing happens (no error or warning ether)

I'm working on a custom ROM for my Toshiba Thrive and I'd like to install some apps with data already placed on installation, but I can't find out how. An example would be ADW as a launcher. Right now, it boots and immediately goes to the welcome screen for a fresh install of ADW. I'd like to make a default theme for ADW so that when someone installs the ROM, they can avoid that initial setup of ADW.

View 1 Replies View RelatedI want to add an extra field to the phonebook on android. The field contains a new contact method and when clicked it should start my own application/intent. I have created my own content provider that stores the information. I want to add this contentProvider to the phonebook in the same way organizations and email are added to the phone book. So how do i do this? I tried adding a new contact method but the field KIND needs an integer input which seems to be predefined to some specific methods (EMAIL, IM, ADDRESS etc)
So do i need to add a new type of KIND or can I link my contentProvider to the phone book so that it shows up as an extra field in the phone book?
All the example codes, tutorials or video I see, there is always one ContentProvider per SQL Table with the SQLiteOpenHelper extension defined as a private static class... Is it some sort of standard design...to have one ContentProvider per SQL Table? Or I can define one generic ContentProvider and use its instance for ever update? Is there some issue with that? Could anyone please help as my application has like 5-6 tables.
View 12 Replies View RelatedMaybe it's an easy question, but I've tried to understand why all the content providers seem not to close the DB that they use. In the NotePadProvider example (in other providers is similar), it's used a Helper to manage the DB (that extends of SQLiteOpenHelper).
This helper has a method to close the DB (http://developer.android.com/ reference/android/database/sqlite/SQLiteOpenHelper.html#close%28%29), but in all the providers that I have seen (even in the example), this method is never used.
For example, in the query method of the NotPadProvider we use the helper to open a DB
CODE:...........
The mOpenHelper is create in the "onCreate()" method, but there is no reference to a mOpenHelper.close() in all the provider (maybe because there is no "close()" method in ContentProvider).
Do we need to close the SQLiteOpenHelper object? When we use it inside a ContentProvider, where is the right place to close it?
I have a custom class, which represents my data-structure. This custom class is in a normal Java-library, which is included in both projects. I have one Project with a ContentProvider which provides this data to Activities of other Projects. And an other Project with an Activity, where I want to handle this data in objects of this custom class.
How can I get this data to the Activity? The Cursor [1] only supports primitive Types.
