URI –

1. Identify your provider
2. Identify different types of data that the provider can work with

URI Structure –

When we want to check a URI tasks, we may have the below statement. But that can be tricky if a string has an integer ID at the end. 

URIMatcher –

As long as the URI has an integer (“/#”) after the initial tasks path, this matcher will recognize it and associate it with the int constant TASK_WITH_ID.
