Public methods

addPackageToPreferred

Added in API level 1

void addPackageToPreferred (String packageName)

此方法已弃用。
这个功能不再做任何事情; 这是一种管理偏好活动的旧方法，已被现代基于活动的偏好取代（并与之冲突）。

Parameters
`packageName`	`String`

addPermission

Added in API level 1

boolean addPermission (PermissionInfo info)

为系统添加一个新的动态权限。为此，您的软件包必须通过清单中的<permission-tree>标记定义权限树。一个包只能向由自己的包或另一个用相同的用户ID定义的树添加权限; 如果许可树与许可树的名称匹配+“。”，则许可在树中：例如，“com.foo.bar”是许可树“com.foo”的成员。

允许您的权限树名称是描述性的，因为您正在占有整套权限名称。因此，它必须位于您控制的域下，其后缀不会与可能在属于该域的任何应用程序中声明的任何常规权限相匹配。

在使用这些权限的任何.apks安装之前，必须添加新权限。通过此方法添加的权限在设备重新启动时会被记住。如果授予的权限已经存在，则您在此提供的信息将用于更新它。

Parameters
`info`	`PermissionInfo`: Description of the permission to be added.

Returns
`boolean`	Returns true if a new permission was created, false if an existing one was updated.

addPermissionAsync

Added in API level 8

boolean addPermissionAsync (PermissionInfo info)

像 addPermission(PermissionInfo)一样，但在从调用返回后异步持久化包管理器状态，允许它更快地返回并批处理一系列添加，但不保证在写入设备之前重新启动设备时添加的权限将保留。

Parameters
`info`	`PermissionInfo`

Returns
`boolean`

addPreferredActivity

Added in API level 1

此方法已弃用。
这是一个受保护的API，应该不可用于第三方应用程序。平台负责分配首选活动，并且不能直接修改。向系统添加一个新的首选活动映射。当Context.startActivity()找到多个匹配活动并且与给定的过滤器匹配时，这将用于自动选择给定的活动组件。

Parameters
`filter`	`IntentFilter`: The set of intents under which this activity will be made preferred.
`match`	`int`: The IntentFilter match category that this preference applies to.
`set`	`ComponentName`: The set of activities that the user was picking from when this preference was made.

Parameters
`pkg1`	`String`: First package name whose signature will be compared.
`pkg2`	`String`: Second package name whose signature will be compared.

Returns
`int`	Returns an integer indicating whether all signatures on the two packages match. The value is >= 0 (`SIGNATURE_MATCH`) if all signatures match or < 0 if there is not a match (`SIGNATURE_NO_MATCH` or `SIGNATURE_UNKNOWN_PACKAGE`).

checkSignatures

Added in API level 5

int checkSignatures (int uid1, 
                int uid2)

像checkSignatures(String, String)一样，但需要检查两个软件包的UID。例如，在IPC中进行检查时，这可能很有用，其中UID是唯一可用的标识。它在功能上与确定与UID相关的包并检查其签名的功能相同。
