@Havic2u , as app launch works
but depends on os level/version....., did you maybe try any edit somewhat related to os
hint...... what 'target' or 'minimum' values within apk is sometimes lowered or increased when trying to test/run on different/specific os versions....... answer below
couple workarounds to 'possibly' resolve the appLauncher 'issue' on higher android_os.... easiest of which would be to simply
lower target sdk of sparkle e.g. from 34 to 29 (android manifest line12 if using mt)
@Havic2u maybe see if this will work for you
although not able to test n confirm if it'll work on a shield or all devices, it seems to work(launch intalled App) just fine n opens flix(or whatever) with sparkle target sdk at 29 having tested on 2 different devices that couldnt launch flix/cinema before the sdk being lowered -
onn4k (os12) with sparkle sdk29 now opens cinema (but couldnt when sparkle was at sdk34)
