Set temporary target SDK until S SDK finalised.

This is required so our tests can be installed and run on R devices
(which is needed because MediaProvider needs to be installed on R
devices). S SDK is not finalized yet and targetting "current" does not
work, so our temporary workaround is to target "10000". We must update
this once S SDK is finalized.

While this is not an ideal approach, we do not have a better alternative
at the moment.
