Screen Sharing Detection

Android devices are capable of sharing (mirroring) their screen with another display. A screen can be shared either wirelessly or using a cable. Screen sharing can, however, pose a security risk, as sensitive information might be leaking from app screens.

Malwarelytics for Android is able to detect that the screen is being shared and can be configured to terminate the app in such a case.


This feature can be configured during the Malwarelytics initialization phase:

val raspConfig = RaspConfig.Builder()
    // configuration of other RASP features

Available values of DetectionConfig:

Value Description
NoAction indicates that screen sharing will not be automatically detected. A manual check is still possible.
Notify indicates that screen sharing will be automatically detected and observers will be notified.
indicates that screen sharing will be automatically detected and the app will be terminated when a screen sharing is automatically detected.

Screen sharing detection defaults to DetectionConfig.Notify.

List of available parameters for some config values:

Parameter Description
exitUrl:String? defines the URL to be opened when the app is terminated because of the automatic detection. Defaults to null.


After initialization, the screen sharing detection feature can be accessed via RaspManager. This can be used to register an observer or to trigger a manual screen sharing detection check.

Registering an Observer

The screen sharing detection can trigger a certain action. To achieve that, an observer needs to be configured and registered.

Observer configuration:

val raspObserver = object : RaspObserver {
    override fun onScreenSharingDetected(screenSharingDetected: Boolean) {
        // handle screen sharing detection
    // handle detection of other RASP features

The observer can be registered in RaspManager. When it is no longer needed, it can be unregistered again.


Triggering a Manual Check

Screen sharing detection check can be triggered manually in RaspManager. Two methods are available – isScreenShared() gives a simple boolean answer, whereas getScreenSharingDetection() provides more details.

val screenSharingDetection = raspManager.getScreenSharingDetection()
val isScreenShared = raspManager.isScreenShared()

More information on general RASP feature configuration and usage can be found in this overview.
