Trusted web activity Unable to start activity ComponentInfo Service Intent must be explicit: Intent

Question

I have integrated Trusted Web Activity in my Android App when launching TwalauncherActivity as main Activity, App is not opening, it's stopping suddenly & closing automatically.

I have followed this link to add Trusted web Activity.

Answer 1

The linked demo is outdated (the link is currently broken too, as the demo was moved here )

This is the current code for the update LauncherActivity , inside the Support Library.

The latest version of the Support Library supporting TWAs is being hosted in JitPack temporarily.

It will be merged into the official support library in the near future.
