To add the partner requested ResourcesProvider#loadFromDir APIs, this change adds format type integer that allows us to reduce the number of ApkAssets loading overrides. This change also adds hidden offset and length based ResourcesProvider APIs that could not make R. Bug: 142716192 Test: atest FrameworksResourceLoaderTests Change-Id: I926fde257cae701901dcd4ca408024feae8c90a6 Merged-In: I926fde257cae701901dcd4ca408024feae8c90a6
