Subject: Get resource based on subId for multi-SIM
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=5f8ac27d79a47b8b237e29677db17a28eb916cd1;p=android-x86%2Fframeworks-base.git

Get resource based on subId for multi-SIM

The resource loading is done based on the last SIM to come up
which is not a deterministic design. Thus, update the way to get
the resource based on the subId.

Test: atest FrameworksNetTests
Test: manually test with avoid bad wifi feature supported sim
Bug: 138956509
