Merge "Remove obsolete Support Library guidance from version_defaults.mk"

# Update this value when the platform version changes (rather

# than overriding it somewhere else).  Can be an arbitrary string.

# When you add a new PLATFORM_VERSION which will result in a new

# PLATFORM_SDK_VERSION please ensure you add a corresponding isAtLeast*

# method in the following java file:

# frameworks/support/compat/gingerbread/android/support/v4/os/BuildCompat.java

# When you change PLATFORM_VERSION for a given PLATFORM_SDK_VERSION

# please add that PLATFORM_VERSION as well as clean up obsolete PLATFORM_VERSION's

# in the following text file:

  # SDK version the branch is based on and PLATFORM_VERSION_CODENAME holds

  # the code-name of the new development work.

  # When you change PLATFORM_SDK_VERSION please ensure you also update the

  # corresponding methods for isAtLeast* in the following java file:

  # frameworks/support/compat/gingerbread/android/support/v4/os/BuildCompat.java

  # When you increment the PLATFORM_SDK_VERSION please ensure you also

  # clear out the following text file of all older PLATFORM_VERSION's:

  # cts/tests/tests/os/assets/platform_versions.txt
