Kenny Root | 05105f7 | 2010-09-22 17:29:43 -0700 | [diff] [blame] | 57 | * StorageManager is the interface to the systems storage service. The storage |
| 58 | * manager handles storage-related items such as Opaque Binary Blobs (OBBs). |
| 59 | * <p> |
| 60 | * OBBs contain a filesystem that maybe be encrypted on disk and mounted |
| 61 | * on-demand from an application. OBBs are a good way of providing large amounts |
| 62 | * of binary assets without packaging them into APKs as they may be multiple |
| 63 | * gigabytes in size. However, due to their size, they're most likely stored in |
| 64 | * a shared storage pool accessible from all programs. The system does not |
| 65 | * guarantee the security of the OBB file itself: if any program modifies the |
| 66 | * OBB, there is no guarantee that a read from that OBB will produce the |
| 67 | * expected output. |
| 68 | * <p> |
