Android Question Widgets id

[Yngveh58]

Hello
Looking for a way to list installed widgets id numbers and names.
In unfiltered logs this appears:

(NullPointerException) java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.String.trim ()' on a null object reference
handleNotifyUpdateAppWidget, appWidgetId = 93
updateAppWidgetView, appWidgetId = 93, v = com.android.launcher3.widget.LauncherAppWidgetHostView {7502f9a VFE .... L. R ..... I. 0.0-0.0 # 17c}

Attach screenshot with and without filter.
This shows up in log even when I have an app in debug mode.
I wonder if this can help the battery discharge faster, which I experience.

Found a pattern in the log.
I can not interpret it but it is repeated all the time.
This is repeated:
