The stock Google TV launcher declares its HOME intent filter with priority 2. Android resolves the Home intent by priority before consulting the preferred activity or the HOME role, and non-system apps are capped at priority 0, so Method 1 records the choice and the system keeps ignoring it. Point people at Method 2 and give the dumpsys commands to confirm it on their device. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Method 1 cannot work on Google TV, and the README currently recommends it first. The reason is not a settings quirk:
com.google.android.apps.tv.launcherxdeclares its HOME intent filter withpriority=2(setupwraith's recovery activity uses 1). Android's resolver (PackageManagerService.chooseBestActivity) returns the higher-priority candidate before it ever consults the preferred activity or the HOME role, andComponentResolver.adjustPrioritycaps non-system apps at 0. So the picker records LTvLauncher as the HOME role holder and the Home key still launches Google TV. Same forcmd package set-home-activity.Checked on a Hisense Google TV, Android 12:
Home key with the picker set to LTvLauncher:
START u0 {act=android.intent.action.MAIN cat=[android.intent.category.HOME] ... cmp=com.google.android.apps.tv.launcherx/.home.HomeActivity} from uid 0.This adds a short note under Method 1 pointing Google TV users at Method 2, with the two dumpsys commands to confirm it on their own device. Docs only.
