+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.

+Resource overlay
+================
+
+
+Introduction
+------------
+
+Overlay packages are special .apk files which provide no code but
+additional resource values (and possibly new configurations) for
+resources in other packages. When an application requests resources,
+the system will return values from either the application's original
+package or any associated overlay package. Any redirection is completely
+transparent to the calling application.
+
+Resource values have the following precedence table, listed in
+descending precedence.
+
+ * overlay package, matching config (eg res/values-en-land)
+
+ * original package, matching config
+
+ * overlay package, no config (eg res/values)
+
+ * original package, no config
+
+During compilation, overlay packages are differentiated from regular
+packages by passing the -o flag to aapt.
+
+
+Background
+----------
+
+This section provides generic background material on resources in
+Android.
+
+
+How resources are bundled in .apk files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Android .apk files are .zip files, usually housing .dex code,
+certificates and resources, though packages containing resources but
+no code are possible. Resources can be divided into the following
+categories; a `configuration' indicates a set of phone language, display
+density, network operator, etc.
+
+ * assets: uncompressed, raw files packaged as part of an .apk and
+           explicitly referenced by filename. These files are
+           independent of configuration.
+
+ * res/drawable: bitmap or xml graphics. Each file may have different
+                 values depending on configuration.
+
+ * res/values: integers, strings, etc. Each resource may have different
+               values depending on configuration.
+
+Resource meta information and information proper is stored in a binary
+format in a named file resources.arsc, bundled as part of the .apk.
+
+Resource IDs and lookup
+~~~~~~~~~~~~~~~~~~~~~~~
+During compilation, the aapt tool gathers application resources and
+generates a resources.arsc file. Each resource name is assigned an
+integer ID 0xppttiii (translated to a symbolic name via R.java), where
+
+ * pp: corresponds to the package namespace (details below).
+
+ * tt: corresponds to the resource type (string, int, etc). Every
+       resource of the same type within the same package has the same
+       tt value, but depending on available types, the actual numerical
+       value may be different between packages.
+
+ * iiii: sequential number, assigned in the order resources are found.
+
+Resource values are specified paired with a set of configuration
+constraints (the default being the empty set), eg res/values-sv-port
+which imposes restrictions on language (Swedish) and display orientation
+(portrait). During lookup, every constraint set is matched against the
+current configuration, and the value corresponding to the best matching
+constraint set is returned (ResourceTypes.{h,cpp}).
+
+Parsing of resources.arsc is handled by ResourceTypes.cpp; this utility
+is governed by AssetManager.cpp, which tracks loaded resources per
+process.
+
+Assets are looked up by path and filename in AssetManager.cpp. The path
+to resources in res/drawable are located by ResourceTypes.cpp and then
+handled like assets by AssetManager.cpp. Other resources are handled
+solely by ResourceTypes.cpp.
+
+Package ID as namespace
+~~~~~~~~~~~~~~~~~~~~~~~
+The pp part of a resource ID defines a namespace. Android currently
+defines two namespaces:
+
+ * 0x01: system resources (pre-installed in framework-res.apk)
+
+ * 0x7f: application resources (bundled in the application .apk)
+
+ResourceTypes.cpp supports package IDs between 0x01 and 0x7f
+(inclusive); values outside this range are invalid.
+
+Each running (Dalvik) process is assigned a unique instance of
+AssetManager, which in turn keeps a forest structure of loaded
+resource.arsc files. Normally, this forest is structured as follows,
+where mPackageMap is the internal vector employed in ResourceTypes.cpp.
+
+mPackageMap[0x00] -> system package
+mPackageMap[0x01] -> NULL
+mPackageMap[0x02] -> NULL
+...
+mPackageMap[0x7f - 2] -> NULL
+mPackageMap[0x7f - 1] -> application package
+
+
+
+The resource overlay extension
+------------------------------
+
+The resource overlay mechanism aims to (partly) shadow and extend
+existing resources with new values for defined and new configurations.
+Technically, this is achieved by adding resource-only packages (called
+overlay packages) to existing resource namespaces, like so:
+
+mPackageMap[0x00] -> system package -> system overlay package
+mPackageMap[0x01] -> NULL
+mPackageMap[0x02] -> NULL
+...
+mPackageMap[0x7f - 2] -> NULL
+mPackageMap[0x7f - 1] -> application package -> overlay 1 -> overlay 2
+
+The use of overlay resources is completely transparent to
+applications; no additional resource identifiers are introduced, only
+configuration/value pairs. Any number of overlay packages may be loaded
+at a time; overlay packages are agnostic to what they target -- both
+system and application resources are fair game.
+
+The package targeted by an overlay package is called the target or
+original package.
+
+Resource overlay operates on symbolic resources names. Hence, to
+override the string/str1 resources in a package, the overlay package
+would include a resource also named string/str1. The end user does not
+have to worry about the numeric resources IDs assigned by aapt, as this
+is resolved automatically by the system.
+
+As of this writing, the use of resource overlay has not been fully
+explored. Until it has, only OEMs are trusted to use resource overlay.
+For this reason, overlay packages must reside in /system/overlay.
+
+
+Resource ID mapping
+~~~~~~~~~~~~~~~~~~~
+Resource identifiers must be coherent within the same namespace (ie
+PackageGroup in ResourceTypes.cpp). Calling applications will refer to
+resources using the IDs defined in the original package, but there is no
+guarantee aapt has assigned the same ID to the corresponding resource in
+an overlay package. To translate between the two, a resource ID mapping
+{original ID -> overlay ID} is created during package installation
+(PackageManagerService.java) and used during resource lookup. The
+mapping is stored in /data/resource-cache, with a @idmap file name
+suffix.
+
+The idmap file format is documented in a separate section, below.
+
+
+Package management
+~~~~~~~~~~~~~~~~~~
+Packages are managed by the PackageManagerService. Addition and removal
+of packages are monitored via the inotify framework, exposed via
+android.os.FileObserver.
+
+During initialization of a Dalvik process, ActivityThread.java requests
+the process' AssetManager (by proxy, via AssetManager.java and JNI)
+to load a list of packages. This list includes overlay packages, if
+present.
+
+When a target package or a corresponding overlay package is installed,
+the target package's process is stopped and a new idmap is generated.
+This is similar to how applications are stopped when their packages are
+upgraded.
+
+
+Creating overlay packages
+-------------------------
+
+Overlay packages should contain no code, define (some) resources with
+the same type and name as in the original package, and be compiled with
+the -o flag passed to aapt.
+
+The aapt -o flag instructs aapt to create an overlay package.
+Technically, this means the package will be assigned package id 0x00.
+
+There are no restrictions on overlay packages names, though the naming
+convention <original.package.name>.overlay.<name> is recommended.
+
+
+Example overlay package
+~~~~~~~~~~~~~~~~~~~~~~~
+
+To overlay the resource bool/b in package com.foo.bar, to be applied
+when the display is in landscape mode, create a new package with
+no source code and a single .xml file under res/values-land, with
+an entry for bool/b. Compile with aapt -o and place the results in
+/system/overlay by adding the following to Android.mk:
+
+LOCAL_AAPT_FLAGS := -o com.foo.bar
+LOCAL_MODULE_PATH := $(TARGET_OUT)/overlay
+
+
+The ID map (idmap) file format
+------------------------------
+
+The idmap format is designed for lookup performance. However, leading
+and trailing undefined overlay values are discarded to reduce the memory
+footprint.
+
+
+idmap grammar
+~~~~~~~~~~~~~
+All atoms (names in square brackets) are uint32_t integers. The
+idmap-magic constant spells "idmp" in ASCII. Offsets are given relative
+to the data_header, not to the beginning of the file.
+
+map          := header data
+header       := idmap-magic <crc32-original-pkg> <crc32-overlay-pkg>
+idmap-magic  := <0x706d6469>
+data         := data_header type_block+
+data_header  := <m> header_block{m}
+header_block := <0> | <type_block_offset>
+type_block   := <n> <id_offset> entry{n}
+entry        := <resource_id_in_target_package>
+
+
+idmap example
+~~~~~~~~~~~~~
+Given a pair of target and overlay packages with CRC sums 0x216a8fe2
+and 0x6b9beaec, each defining the following resources
+
+Name          Target package  Overlay package
