      "message": "New implementation of AssetManager/ResTable\n\nThe multiwindow model and Resources-per-activity\nmodel that came in N puts greater demands on AssetManagers.\nThey are created whenever window dimensions change, which\ncan be frequently. There is a need to be able to cheaply\ncreate a new AssetManager for each Activity, which shares\na lot of underlying state.\n\nIn order to make the creation of AssetManagers cheap,\nwe need a new implementation of the native AssetManager\nand ResTable to support immutable representations of\nAPKs. This new data structure/class is ApkAssets.\n\nApkAssets have the same functionality of an AssetManager, except\nthat they operate on a single APK, and they do not do any caching.\nOnce loaded, they are immutable.\n\nApkAssets will be exposed as a Java object, with its implementation in\nnative code. The existing Java StringBlock will be owned by ApkAssets,\nwhich means that Strings can be shared across AssetManagers.\n\nApkAssets can be cached by the ResourcesManager. Creating an AssetManager\nrequires only a list of ApkAssets and a configuration.\n\nAssetManager2 (named with the suffix \u00272\u0027 for now while transitioning\nto the new implementation) caches bags that are accessed.\n\nSince ApkAssets are expected to be kept around longer, they do more validation\nof the resource table, which cause slower load times. Measured on an angler-userdebug,\nloading the framework assets takes 11ms with ApkAssets, and 2ms with the old\nAssetManager implementation.\n\nThe tradeoff is that there does not need to be any security checks once an ApkAssets\nis loaded, and regular resource retrieval is faster. Measured on an angler-userdebug,\naccessing resource (android:string/ok) with many locales takes 18us with AssetManager2,\nand 19us with AssetManager (this is per resource, so these add up).\n\nTest: make libandroidfw_tests\nChange-Id: Id0e57ee828f17008891fe3741935a9be8830b01d\n"
