Black screen on Android with freshly scaffolded example app

[nick-stebbings]

I cannot get past this black screen (inside a Tauri window on my mobile) using: Linux Mint 21.1, Android 14 on a Samsung Galaxy A15

After

• scaffolding a new app
• following all instructions on the Android p2p setup page,
• entering the android nix shell
• disabled firewall
• checking adb devices and seeing my phone listed
• running network android command

The app appears in a tauri window on my laptop OK. I assume this might be some kind of networking issue between the processes that is not properly sharing the UI.

Here is the output:

Any help would be appreciated :) Cheers

Hi Nick! At first glance I can't really tell what's going wrong... Things that could help:

• Are the two devices in the same network?
• What do you see in the logs when you do adb logcat? You'd need to filter by the identifier of your app to get a clearer picture.
• If you use tauri_plugin_holochain::async_init instead of tauri_plugin_holochain::init, does the same happen? async_init does not wait for holochain to start before starting your UI.
• The newer version of tauri (tauri v2.0.0-rc.0) changes the way the mobile devices connect to the UI to it being a local development server running in the phone. The latest changes in the shipyard main branch already work with rc, so need to cargo update and also run through tauri's upgrade guide.

Hope this helps!

Great, it works! It was the final bullet point that did it (the release candidate fixes all the display issues).

Thanks for your help Guillem (and the whole team for all the hard work on this)!
