Brief description of the drawings
Fig. 1 is the method and step schematic diagram of the present invention.
Embodiment
All features disclosed in this specification, can be with any in addition to mutually exclusive feature and/or step
Mode is combined.
The present invention is elaborated with reference to Fig. 1.
Step one：Activation equipment manager, and equipment manager example is obtained, to obtain the control authority of camera；
(1) method of the example of acquisition equipment manager is；Android is when realizing equipment manager, it is necessary first to
A broadcast recipients are registered in manifest.xml.
(2) the equipment manager list mActiveAdmins activated is obtained by the method in step (1), and returned
Return mActiveAdmins setting equipment manager list.Obtain all have registered
DeviceAdminReceiver.ACTION_DEVICE_ADMIN_ENABLED is Android.app.DEVICE_ADMIN_
ENABLED action broadcast recipients' list avail.If the broadcast recipients for including the action using have registered are simultaneously
And equipment manager is have activated, it will be shown in setting equipment manager list.
(3) android.app.action.DEVICE_ADMIN_ENABLED action application activating is registered as equipment
Manager.Decompiling.Connected the equipment manager list a activated of DevicePolicyManager acquisitions and passed through
The list b that traversal have registered android.app.action.DEVICE_ADMIN_ENABLED action is contrasted, if
It was found that the equipment manager in list a occurs not in list b, following code ejection is just called to cancel activation
Activity, allows user to cancel manually.
Directly invoke DevicePolicyManager's after finding the equipment manager using this leak
RemoveActiveAdmin methods cancel activation, and this method needs more than system authorities to perform.
Obtain abnormal in DeviceAdminSettings, installed with normal equipment manager program, normal Activate, so
The meta-data configurations of the program are deleted afterwards, apk are generated, to be installed in the form of updating installation in android equipment.Equipment
Manager have registered android.app.action.DEVICE_ADMIN_ENABLED, so being leaked using above-mentioned equipment control
Hole patch.
Two kinds of method analyses for cancelling activation can be drawn from the analysis above for equipment manager leak patch apk：
First, the equipment manager list activated that DevicePolicyManager is obtained, starts and cancels activation
activity.Test result is unworkable, because DeviceAdminAdd is also required to parse the information in meta-data.
2nd, get after the equipment manager list of activation, can directly invoke DevicePolicyManager's
RemoveActiveAdmin methods cancel activation, test result success, but need more than system authority.Using normal
Apk activation equipment managers, then avoid equipment manager from being cancelled using abnormal apk.
Step 2：Equipment strategy manager instance is obtained using getSystemService ()；
Android platform provides system-level equipment control ability by equipment control API first.How one is obtained
Equipment manager example, its method is：
(1) define and state strategy
A kind of strategy for providing and supporting in functional plane is defined first, and the strategy of this statement corresponds to
The strategy process of some relevant devices in DevicePolicyManager, for example, define minimum password length or minimum capitalization
Number of letters.If a program is attempted to call the method without relative strategy in xml, this will can operationally cause one
SecurityException is abnormal.Program uses the part for forcing lock to activate processing as equipment manager, statement strategy
List will be shown to user in system screen.
(2) broadcast recipients of an equipment control are created
The broadcast recipients of an equipment control are created, it can receive the logical of the event relevant with stating the strategy of support
Know.One program can selectively rewrite call back function.
In same program, Device Admin, when equipment manager (device administrator) account quilt
When user is set to disabling, the strategy configured will be wiped from shared preference.It should consider to realize and application
The relevant service logic of situation.The mitigation security risk for example, program may take some actions to, such as by being implemented in combination with
Sensitive data on sweep equipment, disables remote synchronization, reminds keeper.
If selected " Activate ", program will turn into equipment manager and can be initially configured and enforce plan
Slightly.
The program is also required to carry out the preparation for the Reset Status that processing user abandons activation, such as clicks on " cancellation " button,
Return key or HOME keys.Therefore onResume () method in strategy setting Activity needs service logic and come again
Such case is assessed, and is presented to user equipment management activation option to user, if necessary,.
(3) equipment strategy controller is realized
After equipment manager is successfully activated, program will configure equipment strategy manager according to the strategy of request.
Remember that new strategy will be added in each issue in Android.Platform release inspection is carried out in program, to detect
Can new strategy be supported well by early version platform.
So program just can be with implementation strategy.Pass through equipment strategy manager (Device Policy Manager) API
It can be determined that whether current password is applied to the strategy of request.Equipment control (device administration) API will not
Automatic correction.
Step 3：Whether detection device manager activates to the control authority of camera, otherwise, utilizes
StartActivity () pop-up device manager authority theactivewindow is with control authority of the activation equipment manager to camera；
Detect whether to open equipment manager equipment, its method is：
Activation is, it is necessary to apply to three classes when checking equipment manager；
DevicePolicyManager is, it is necessary to coordinate DeviceAdminReceiver to use.
DeviceAdminReceiver Similar integrals BroadcastReceiver.Realize an OnReceiver side
According to different Action in method, this method, corresponding operation is performed.If activated successfully, then Action is exactly ACTION_
DEVICE_ADMIN_ENABLED, calls onEnabled methods accordingly.
DeviceAdminInfo realizes step：
A. a broadcast type, the change for monitoring right are registered in androidmanifest.xml；
B. the inventory of creative management authority；Xml document folder is created under res file, then is created
lockourscreen.xml；
C. broadcast type deviceAdminReceiver is created to inherit DeviceAdminReceiver and realize corresponding
Method；
D. the operation of related management authority is activated；
