android-Creating a Content Provider（2）

For content URIs that point to a row or rows of table data,

getType()

should
return a MIME type in Android's vendor-specific MIME format:

Type part:

vnd

Subtype part:

If the URI pattern is for a single row:

android.cursor.item/

If the URI pattern is for more than one row:

android.cursor.dir/

Provider-specific part:

vnd.<name>

.

<type>

You supply the

<name>

and

<type>

. The

<name>

value should be globally unique, and the

<type>

value should be unique to the corresponding
URI pattern. A good choice for

<name>

is your company's name or some part of your application's Android package name. A good choice for the

<type>

is a string that identifies the table associated with the URI.

Attributes that specify the permissions that other applications must have in order
to access the provider's data:

android:grantUriPermssions

: Temporary permission
flag.

android:permission

: Single provider-wide read/write
permission.

android:readPermission

: Provider-wide read
permission.

android:writePermission

: Provider-wide write
permission.

Permissions and their corresponding attributes are described in more detail in the section Implementing
Content Provider Permissions.
