public virtual Android.Content.Intent SetIdentifier (string? identifier);

[<Android.Runtime.Register("setIdentifier", "(Ljava/lang/String;)Landroid/content/Intent;", "GetSetIdentifier_Ljava_lang_String_Handler", ApiSince=29)>]
abstract member SetIdentifier : string -> Android.Content.Intent

Parameters

Attributes: RegisterAttribute

Remarks

Set an identifier for this Intent. If set, this provides a unique identity for this Intent, allowing it to be unique from other Intents that would otherwise look the same. In particular, this will be used by #filterEquals(Intent) to determine if two Intents are the same as with other fields like #setAction. However, unlike those fields, the identifier is <em>never</em> used for matching against an IntentFilter; it is as if the identifier has not been set on the Intent.

This can be used, for example, to make this Intent unique from other Intents that are otherwise the same, for use in creating a android.app.PendingIntent. (Be aware however that the receiver of the PendingIntent will see whatever you put in here.) The structure of this string is completely undefined by the platform, however if you are going to be exposing identifier strings across different applications you may need to define your own structure if there is no central party defining the contents of this field.
