[android-developers] Help with Content Providers / Content Resolvers

2011-01-10 Thread Pedro Duque 
Hi,

I'm developing an editor for my application data. This application has a
free and a premium version, so each one has it's own content provider with
different authorities to avoid clashes. The editor also have a local content
provider so it can work standalone.

What I want to do is to check for a content provider existence when I start
the editor so I can choose to use the local one, the one from the free
application or the one from the premium application. I've search the
documentation but I can't find a way to list the content providers
available, for ex., for a specific MIME type.

Can somebody help me?

Regards,
PMD

The mime type mapping works in the other direction: once you have a 
ContentProvider (or more specifically, a URI for a data query) it can be 
used to get the mime type.


For your task, take a look at:

http://developer.android.com/reference/android/content/pm/PackageManager.html#queryContentProviders(java.lang.String, 
int, int)


If both lite / pro versions share the same user id, you can try using 
that for the first parameter. If not, just filter the results by 
authority (since you know what you expect).


You can also use:

http://developer.android.com/reference/android/content/pm/PackageManager.html#getProviderInfo(android.content.ComponentName, 
int)


by calling it with the lite / pro authorities and checking the return value.
