When building external storage paths, always include user in path to enable cross-user paths and aid debugging. Each Zygote process continues to only have access to the appropriate user-specific emulated storage through bind mounts. A second set of mounts continue supporting legacy /sdcard-style paths. For example, a process running as owner has these mount points: /storage/emulated_legacy /storage/emulated_legacy/Android/obb /storage/emulated/0 /storage/emulated/obb Since Environment is created before Zygote forks, we need to update its internal paths after each process launches.
