This issuss because mi2 use a FAT partition as external storage. when add users, MountService create EmulatedVolume will crash. see detail on com.android.server.MountService.createEmulatedVolumeForUserLocked(UserHandle) and com.android.server.MountService.readStorageListLocked()

M1cha commented 9 years ago

that's wrong. mi2 uses ext4 for external storage. look at fstab.

zx121122 commented 9 years ago

see overlay/frameworks/base/core/res/res/xml/storage_list.xml external storage is not emulated, so com.android.server.MountService.readStorageListLocked() will not create mEmulatedTemplate and mEmulatedTemplate is null. When MountService recieved Intent.ACTION_USER_ADDED to create an emulated volume for user, mEmulatedTemplate is null so MountService throw an exception. -> system_server crash

thx for this information. still - mi2 uses ext4 not vfat ;)

@M1cha you need to disable multiple users :( Only datamedia device can use this feature
