addPermission

public abstract boolean addPermission(PermissionInfo info)

Add a new dynamic permission to the system. For this to work, your package must have defined a permission tree through the <permission-tree> tag in its manifest. A package can only add permissions to trees that were defined by either its own package or another with the same user id; a permission is in a tree if it matches the name of the permission tree + ".": for example, "com.foo.bar" is a member of the permission tree "com.foo".

It is good to make your permission tree name descriptive, because you are taking possession of that entire set of permission names. Thus, it must be under a domain you control, with a suffix that will not match any normal permissions that may be declared in any applications that are part of that domain.

New permissions must be added before any .apks are installed that use those permissions. Permissions you add through this method are remembered across reboots of the device. If the given permission already exists, the info you supply here will be used to update it.

Parameters:: info - Description of the permission to be added.
Returns:: Returns true if a new permission was created, false if an existing one was updated.
Throws:: SecurityException - if you are not allowed to add the given permission name.
See Also:: removePermission(String)

removePermission

public abstract void removePermission(String name)

Removes a permission that was previously added with addPermission(PermissionInfo). The same ownership rules apply -- you are only allowed to remove permissions that you are allowed to add.

Parameters:: name - The name of the permission to remove.
Throws:: SecurityException - if you are not allowed to remove the given permission name.
See Also:: addPermission(PermissionInfo)

checkSignatures

public abstract int checkSignatures(String pkg1,
                                    String pkg2)

Compare the signatures of two packages to determine if the same signature appears in both of them. If they do contain the same signature, then they are allowed special privileges when working with each other: they can share the same user-id, run instrumentation against each other, etc.

Parameters:: pkg1 - First package name whose signature will be compared.; pkg2 - Second package name whose signature will be compared.
Returns:: Returns an integer indicating whether there is a matching signature: the value is >= 0 if there is a match (or neither package is signed), or < 0 if there is not a match. The match result can be further distinguished with the success (>= 0) constants SIGNATURE_MATCH, SIGNATURE_NEITHER_SIGNED; or failure (< 0) constants SIGNATURE_FIRST_NOT_SIGNED, SIGNATURE_SECOND_NOT_SIGNED, SIGNATURE_NO_MATCH, or SIGNATURE_UNKNOWN_PACKAGE.
See Also:: SIGNATURE_MATCH, SIGNATURE_NEITHER_SIGNED, SIGNATURE_FIRST_NOT_SIGNED, SIGNATURE_SECOND_NOT_SIGNED, SIGNATURE_NO_MATCH, SIGNATURE_UNKNOWN_PACKAGE

getPackagesForUid

public abstract String[] getPackagesForUid(int uid)

Retrieve the names of all packages that are associated with a particular user id. In most cases, this will be a single package name, the package that has been assigned that user id. Where there are multiple packages sharing the same user id through the "sharedUserId" mechanism, all packages with that id will be returned.

Parameters:: uid - The user id for which you would like to retrieve the associated packages.
Returns:: Returns an array of one or more packages assigned to the user id, or null if there are no known packages with the given id.

getNameForUid

public abstract String getNameForUid(int uid)

Retrieve the official name associated with a user id. This name is guaranteed to never change, though it is possibly for the underlying user id to be changed. That is, if you are storing information about user ids in persistent storage, you should use the string returned by this function instead of the raw user-id.

Parameters:: uid - The user id for which you would like to retrieve a name.
Returns:: Returns a unique name for the given user id, or null if the user id is not currently assigned.

getInstalledApplications

public abstract List<ApplicationInfo> getInstalledApplications(int flags)

Return a List of all application packages that are installed on the device.

Parameters:: flags - Additional option flags. Currently should always be 0.

public abstract void freeApplicationCache(long freeStorageSize,
                                          IPackageDataObserver observer)

Free storage by deleting LRU sorted list of cache files across all applications. If the currently available free storage on the device is greater than or equal to the requested free storage, no cache files are cleared. If the currently available storage on the device is less than the requested free storage, some or all of the cache files across all applications are deleted(based on last accessed time) to increase the free storage space on the device to the requested value. There is no gurantee that clearing all the cache files from all applications will clear up enough storage to achieve the desired value.

Parameters:: freeStorageSize - The number of bytes of storage to be freed by the system. Say if freeStorageSize is XX, and the current free storage is YY, if XX is less than YY, just return. if not free XX-YY number of bytes if possible.; observer - callback used to notify when the operation is completed IPackageDataObserver.onRemoveCompleted(String, boolean) will be called when that happens. observer may be null to indicate that no callback is desired.
