Register(Object, Object)

Add a new callback to the list.

[Android.Runtime.Register("register", "(Landroid/os/IInterface;Ljava/lang/Object;)Z", "GetRegister_Landroid_os_IInterface_Ljava_lang_Object_Handler")]
public virtual bool Register (Java.Lang.Object? callback, Java.Lang.Object? cookie);
[<Android.Runtime.Register("register", "(Landroid/os/IInterface;Ljava/lang/Object;)Z", "GetRegister_Landroid_os_IInterface_Ljava_lang_Object_Handler")>]
abstract member Register : Java.Lang.Object * Java.Lang.Object -> bool
override this.Register : Java.Lang.Object * Java.Lang.Object -> bool

Parameters

callback
Object

The callback interface to be added to the list. Must not be null -- passing null here will cause a NullPointerException. Most services will want to check for null before calling this with an object given from a client, so that clients can't crash the service with bad data.

cookie
Object

Optional additional data to be associated with this callback.

Returns

Boolean

Returns true if the callback was successfully added to the list. Returns false if it was not added, either because #kill had previously been called or the callback's process has gone away.

Attributes
RegisterAttribute

Remarks

Add a new callback to the list. This callback will remain in the list until a corresponding call to #unregister or its hosting process goes away. If the callback was already registered (determined by checking to see if the IInterface#asBinder callback.asBinder() object is already in the list), then it will be left as-is. Registrations are not counted; a single call to #unregister will remove a callback after any number calls to register it.
