Runtime resource overlay allows unmodified applications to appear as if they had been compiled with additional resources defined. See libs/utils/README for more information. This commit is the first iteration of runtime resource overlay. It provides the actual overlay modifications and loading of trusted overlay packages (ie residing in /vendor) targeting framework-res.apk. This commit loads exactly one overlay package. The overlay, if present, must target framework-res.apk and be located at /vendor/overlay/framework/framework-res.apk. Change-Id: If26ee7754813004a96c043dba37fbe99fa3919db
Unit tests for runtime resource overlay ======================================= As of this writing, runtime resource overlay is only triggered for /system/framework/framework-res.apk. Because of this, installation of overlay packages require the Android platform be rebooted. However, the regular unit tests (triggered via development/testrunner/runtest.py) cannot handle reboots. As a workaround, this directory contains a shell script which will trigger the tests in a non-standard way. Once runtime resource overlay may be applied to applications, the tests in this directory should be moved to core/tests/coretests. Also, by applying runtime resource overlay to a dedicated test application, the test cases would not need to assume default values for non-overlaid resources.
