Attributes

Remarks

Call a provider-defined method. This can be used to implement interfaces that are cheaper and/or unnatural for a table-like model.

<p class="note"><strong>WARNING:</strong> The framework does no permission checking on this entry into the content provider besides the basic ability for the application to get access to the provider at all. For example, it has no idea whether the call being executed may read or write data in the provider, so can't enforce those individual permissions. Any implementation of this method <strong>must</strong> do its own permission checks on incoming calls to make sure they are allowed.</p>
