Apps list keeps the widescreen 64dp side padding after rotating back to portrait

[kasnder]

Symptom. On the Apps tab of the main screen, the app list stays inset by 64dp on each side after opening the app in widescreen (landscape / any window >= 820dp wide) and rotating back to portrait. The widescreen layout is retained until the activity is recreated.

Repro. Open TrackerControl in widescreen so the values-w820dp config applies, then rotate to portrait. The list keeps the 64dp inset; rotating again does not fix it. A fresh portrait launch is unaffected.

Root cause. ActivityMain declares android:configChanges="orientation|screenSize" (AndroidManifest.xml:82), so rotation does not recreate the activity. The llApps container's horizontal padding (app/src/main/res/layout/main.xml:99-102, @dimen/activity_horizontal_margin) is resolved at inflation time — 64dp under values-w820dp/dimens.xml, 0dp in the base values/dimens.xml — and the already-inflated views keep the stale wide-screen value. onConfigurationChanged (ActivityMain.java:612) is a no-op for this case, so nothing re-applies the portrait-resolved padding.

Note. The Timeline tab has no such inset, so the Apps list is inconsistent with it on wide screens anyway.

Fix direction. Either re-apply the resource-resolved padding to llApps in onConfigurationChanged (e.g. read activity_horizontal_margin from getResources() and setPadding), or drop the horizontal padding attributes from llApps so it is full-bleed like the Timeline. The other activities carrying configChanges="orientation|screenSize" in the manifest may share the same latent issue.
