Enumerations

Anonymous Enum 106

Declared in android/storage_manager.h

 Anonymous Enum 106

The different states of a OBB storage passed to AStorageManager_obbCallbackFunc().

Properties
AOBB_STATE_ERROR_ALREADY_MOUNTED	The OBB has already been mounted. Can be returned as the status for callbacks made during asynchronous OBB actions.
AOBB_STATE_ERROR_COULD_NOT_MOUNT	The OBB could not be mounted by the system. Can be returned as the status for callbacks made during asynchronous OBB actions.
AOBB_STATE_ERROR_COULD_NOT_UNMOUNT	The OBB could not be unmounted. This most likely indicates that a file is in use on the OBB. Can be returned as the status for callbacks made during asynchronous OBB actions.
AOBB_STATE_ERROR_INTERNAL	There was an internal system error encountered while trying to mount the OBB. Can be returned as the status for callbacks made during asynchronous OBB actions.
AOBB_STATE_ERROR_NOT_MOUNTED	A call was made to unmount the OBB when it was not mounted. Can be returned as the status for callbacks made during asynchronous OBB actions.
AOBB_STATE_ERROR_PERMISSION_DENIED	The current application does not have permission to use this OBB. This could be because the OBB indicates it's owned by a different package. Can be returned as the status for callbacks made during asynchronous OBB actions.
AOBB_STATE_MOUNTED	The OBB container is now mounted and ready for use. Can be returned as the status for callbacks made during asynchronous OBB actions.
AOBB_STATE_UNMOUNTED	The OBB container is now unmounted and not usable. Can be returned as the status for callbacks made during asynchronous OBB actions.

Anonymous Enum 55

Declared in android/obb.h

 Anonymous Enum 55

Flag for an obb file, returned by AObbInfo_getFlags().

Properties
AOBBINFO_OVERLAY	overlay

Typedefs

AObbInfo

Declared in android/obb.h

struct AObbInfo AObbInfo

AObbInfo is an opaque type representing information for obb storage.

AStorageManager

Declared in android/storage_manager.h

struct AStorageManager AStorageManager

AStorageManager manages application OBB storage, a pointer can be obtained with AStorageManager_new().

AStorageManager_obbCallbackFunc

Declared in android/storage_manager.h

void(* AStorageManager_obbCallbackFunc)(const char *filename, const int32_t state, void *data)

Callback function for asynchronous calls made on OBB files.

"state" is one of the following constants:

• AOBB_STATE_MOUNTED
• AOBB_STATE_UNMOUNTED
• AOBB_STATE_ERROR_INTERNAL
• AOBB_STATE_ERROR_COULD_NOT_MOUNT
• AOBB_STATE_ERROR_COULD_NOT_UNMOUNT
• AOBB_STATE_ERROR_NOT_MOUNTED
• AOBB_STATE_ERROR_ALREADY_MOUNTED
• AOBB_STATE_ERROR_PERMISSION_DENIED

Functions

AObbInfo_delete

Declared in android/obb.h

void AObbInfo_delete(
  AObbInfo *obbInfo
)

Destroy the AObbInfo object.

You must call this when finished with the object.

AObbInfo_getFlags

Declared in android/obb.h

int32_t AObbInfo_getFlags(
  AObbInfo *obbInfo
)

Get the flags of an OBB file.

AObbInfo_getPackageName

Declared in android/obb.h

const char * AObbInfo_getPackageName(
  AObbInfo *obbInfo
)

Get the package name for the OBB.

AObbInfo_getVersion

Declared in android/obb.h

int32_t AObbInfo_getVersion(
  AObbInfo *obbInfo
)

Get the version of an OBB file.

AObbScanner_getObbInfo

Declared in android/obb.h

AObbInfo * AObbScanner_getObbInfo(
  const char *filename
)

Scan an OBB and get information about it.

AStorageManager_delete

Declared in android/storage_manager.h

void AStorageManager_delete(
  AStorageManager *mgr
)

Release AStorageManager instance.

AStorageManager_getMountedObbPath

Declared in android/storage_manager.h

const char * AStorageManager_getMountedObbPath(
  AStorageManager *mgr,
  const char *filename
)

Get the mounted path for an OBB.

AStorageManager_isObbMounted

Declared in android/storage_manager.h

int AStorageManager_isObbMounted(
  AStorageManager *mgr,
  const char *filename
)

Check whether an OBB is mounted.

AStorageManager_mountObb

Declared in android/storage_manager.h

void AStorageManager_mountObb(
  AStorageManager *mgr,
  const char *filename,
  const char *key,
  AStorageManager_obbCallbackFunc cb,
  void *data
)

Attempts to mount an OBB file.

This is an asynchronous operation.

Since API level 33, this function can only be used to mount unencrypted OBBs, i.e. the

key 

parameter must be

null 

or an empty string. Note that even before API level 33, mounting encrypted OBBs didn't work on many Android device implementations. Applications should not assume any particular behavior when

key 

is nonempty.

AStorageManager_new

Declared in android/storage_manager.h

AStorageManager * AStorageManager_new()

Obtains a new instance of AStorageManager.

AStorageManager_unmountObb

Declared in android/storage_manager.h

void AStorageManager_unmountObb(
  AStorageManager *mgr,
  const char *filename,
  const int force,
  AStorageManager_obbCallbackFunc cb,
  void *data
)

Attempts to unmount an OBB file.

This is an asynchronous operation.
