Custom content providers in android

I am trying to create my own ContentProvider so that more than one application (activity?) Can access it. I have a few questions on how to do this,

How do I declare in code that it is a ContentProvider? How do other apps (actions?) Use or import the ContentProvider?

In addition to the extensive developer guide section on content providers , you can check out the Notepad Tutorial and Note Pad Sample Code for information on creating your own content providers.

In the manifest of the application providing the content you would have:

<provider android:name="Inventory" android:authorities="com.package.name.Inventory" />

And in the application receiving the content

    String inventoryItem = "dunno";
       try {
          Uri getItem = Uri.parse(
            "content://com.package.name.Inventory/database_items");
            String[] projection = new String[] { "text" };
            Cursor cursor = managedQuery(getItem, projection, null, null, null);
            if (null != cursor && cursor.moveToNext()) {
              int index = cursor.getColumnIndex("text");
              inventoryItem = cursor.getString(index));     
            }
            cursor.close();
       } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
       }


In an external program, this will return the item specified by item_socks, but this is just a general example of having only one item specified by that name. You will be querying a database table named database_items that looks something like this:

id | name | text

1 | item_socks | brown couple red stripe

inventoryItem will then be equal to "brown pair red stripe"
