Activity Guard

App Shielding offers the option to protect applications from task hijacking. This is enabled by adding the ShieldSDK-activity-guard Maven dependency.

MyApplication/app/build.gradle:

dependencies {
  ...
  implementation 'no.promon.shield:ShieldSDK-activity-guard:7.0.2'
}

This dependency, in combination with the Shielding Tool injects a launcher activity into the app that replaces all existing ones. The injected activity is constructed so that it will always launch and cannot be hijacked. It then evaluates the state of all tasks belonging to the app, and restores or destroys them as appropriate.

A Callback is notified with TaskHijackingData information about the offending app when a task hijacking is attempted.
