#
# This Android.make allows apitrace to be included in an Android AOSP build
# e.g. in a manifest like this:
#
#  <manifest>
#      <remote name="aleksander0m" fetch="https://github.com/aleksander0m/" />
#      <project path="external/apitrace" name="apitrace.git" remote="aleksander0m" revision="aosp" groups="default" />
#  </manifest>
#
# This build file is based on the original one prepared for FirefoxOS and
# removed in commit 173fda8d, and therefore it has the same issues as that
# one:
#
#  * The $(linked_module) targets for both apitrace and egltrace are overriden,
#    which generates some warnings during build as soon as the build system
#    detects the issue.
#
#  * The $(LOCAL_INSTALLED_MODULE) target for egltrace has the same issue.
#
#  * This file overrides the installation steps so that the custom built
#    library and program are installed where we want them. But this file
#    doesn't provide rules to clean the intermediate files :/
