Called by the system every time a client explicitly starts the service by calling android.content.Context#startService, providing the arguments it supplied and a unique integer token representing the start request.

[Android.Runtime.Register("onStartCommand", "(Landroid/content/Intent;II)I", "GetOnStartCommand_Landroid_content_Intent_IIHandler")]
public virtual Android.App.StartCommandResult OnStartCommand (Android.Content.Intent? intent, Android.App.StartCommandFlags flags, int startId);

[<Android.Runtime.Register("onStartCommand", "(Landroid/content/Intent;II)I", "GetOnStartCommand_Landroid_content_Intent_IIHandler")>]
abstract member OnStartCommand : Android.Content.Intent * Android.App.StartCommandFlags * int -> Android.App.StartCommandResult
override this.OnStartCommand : Android.Content.Intent * Android.App.StartCommandFlags * int -> Android.App.StartCommandResult

Parameters

intent: Intent

The Intent supplied to android.content.Context#startService, as given. This may be null if the service is being restarted after its process has gone away, and it had previously returned anything except #START_STICKY_COMPATIBILITY.

flags: StartCommandFlags

Additional data about this start request.

startId: Int32

A unique integer representing this specific request to start. Use with #stopSelfResult(int).

Returns

StartCommandResult

The return value indicates what semantics the system should use for the service's current started state. It may be one of the constants associated with the #START_CONTINUATION_MASK bits.

Attributes: RegisterAttribute

Remarks

For backwards compatibility, the default implementation calls #onStart and returns either #START_STICKY or #START_STICKY_COMPATIBILITY.

<p class="caution">Note that the system calls this on your service's main thread. A service's main thread is the same thread where UI operations take place for Activities running in the same process. You should always avoid stalling the main thread's event loop. When doing long-running operations, network calls, or heavy disk I/O, you should kick off a new thread, or use android.os.AsyncTask.
