Remarks

Violation raised when your app launches an Intent which originated from outside your app.

Violations may indicate security vulnerabilities in the design of your app, where a malicious app could trick you into granting Uri permissions or launching unexported components. Here are some typical design patterns that can be used to safely resolve these violations: <ul> <li>The ideal approach is to migrate to using a PendingIntent, which ensures that your launch is performed using the identity of the original creator, completely avoiding the security issues described above. <li>If using a PendingIntent isn't feasible, an alternative approach is to create a brand new Intent and carefully copy only specific values from the original Intent after careful validation. </ul>

Note that this <em>may</em> detect false-positives if your app sends itself an Intent which is first routed through the OS, such as using Intent#createChooser. In these cases, careful inspection is required to determine if the return point into your app is appropriately protected with a signature permission or marked as unexported. If the return point is not protected, your app is likely vulnerable to malicious apps.
