Constructors Summary
Methods Summary
public static boolean isValidRemoteMessenger(android.os.Messenger messenger)
Returns true if the messenger object is valid.
The messenger constructor and unparceling code does not check whether the provided IBinder is a valid IMessenger object. As a result, it's possible for a peer to send an invalid IBinder that will result in crashes downstream. This method checks that the messenger is in a valid state.
try { return messenger != null && messenger.getBinder() != null; } catch (NullPointerException ex) { // If the messenger was constructed with a binder interface other than // IMessenger then the call to getBinder() will crash with an NPE. return false; }
