How to use tauri mobile? | Tauri Apps | Page 1

I'm trying to get tauri mobile to work for android but I seem to be getting errors. I followed all the steps on https://next--tauri.netlify.app/next/guides/getting-started/prerequisites/windows/#android.
I ran cargo mobile init and initialised the project to bevy-demo, but then cargo run creates these errors (first image)
Does anyone know how to fix this/if i got setup wrong? I'm actually trying to get this working with pnpm but I couldn't find how to get that working so I just tried it with cargo for now.

lament portal I'm trying to get tauri mobile to work for android but I seem to be getting erro...

Try:

#

cargo tauri android dev

#

Oh you're using that one

Announcing the Tauri Mobile Alpha Release | Tauri Apps

Tauri mobile is here! The first alpha release 2.0.0-alpha.0 has been published.

#

Update dependencies to those listed here

#

Then maybe try:

#

cargo mobile android dev

celest garden Apr 27, 2023, 3:24 AM

#

Through pnpm, that command is pnpm tauri android init

odd sandal Apr 27, 2023, 3:24 AM

#

You can install the cratesio version

#

cargo install tauri-cli --version "^2.0.0-alpha"

celest garden Apr 27, 2023, 3:25 AM

#

You haven't installed Tauri with Cargo, so you're getting the error message that Cargo can't find the sub-command tauri.

odd sandal Apr 27, 2023, 3:27 AM

#

Ye

#

Alpha

lament portal Apr 27, 2023, 3:27 AM

#

Alright I'll have a try

odd sandal Apr 27, 2023, 3:28 AM

#

That mobile project is uhh related but not release

lament portal Apr 27, 2023, 3:28 AM

#

celest garden Through pnpm, that command is `pnpm tauri android init`

Is the project initialisation the same as create-tauri-app?

celest garden Apr 27, 2023, 3:29 AM

#

If you use the alpha for create-tauri-app, it should do it for you.

lament portal Apr 27, 2023, 3:29 AM

#

odd sandal That `mobile` project is uhh related but not release

Oh is there a different one I should be using?

#

Alright

odd sandal Apr 27, 2023, 3:30 AM

#

lament portal Oh is there a different one I should be using?

Ye- so it's:
cargo create-tauri-app
[cargo tauri android init]
cargo tauri android dev

odd sandal Apr 27, 2023, 3:30 AM

#

celest garden If you use the alpha for create-tauri-app, it should do it for you.

Wha- the blog didn't mention the alpha.

celest garden Apr 27, 2023, 3:31 AM

#

https://tauri.app/blog/2023/03/01/create-tauri-app-version-3-released

create-tauri-app Version 3 Released | Tauri Apps

create-tauri-app Version 3 is released with support for alpha versions of Tauri, mobile project support and DX improvements

odd sandal Apr 27, 2023, 3:32 AM

#

Ohhh woww

#

So it inits mobile automatically?

celest garden Apr 27, 2023, 3:33 AM

#

It looks like the first error you posted is an error in bevy, not Tauri. It looks like bevy implements winit for itself; does bevy have mobile support?

lament portal Apr 27, 2023, 3:53 AM

#

its taken like 8 m to start 🙃 is this normal?

odd sandal Apr 27, 2023, 3:55 AM

#

Idk i dont use bevy

lament portal Apr 27, 2023, 3:55 AM

#

using pnpm rn

#

i connected it to my phone and i think its working but its just a black screen rn

#

nvm its not lmao

#

do u know what this means?

#

on my phone it says "The web page at https://tauri.localhost/ could not be loaded because: net::ERR_CONNECTION_REFUSED"

celest garden Apr 27, 2023, 4:15 AM

#

For the dev server on mobile, you need to give it your local IP (https://next--tauri.netlify.app/next/mobile/development/configuration#frontend-configuration).

lament portal Apr 27, 2023, 4:16 AM

#

i think create-tauri-app already did that?

#

in vite.config.ts

celest garden Apr 27, 2023, 4:17 AM

#

Yep.

#

It's weird that the connection would be getting refused then. Do you have a firewall setup?

lament portal Apr 27, 2023, 4:18 AM

#

i dont think so, how do i check?

celest garden Apr 27, 2023, 4:19 AM

#

If you didn't set it up, it shouldn't be a problem.

#

Windows has a default one but it's a pretty relaxed ruleset and hasn't caused any issues that I know of.

#

Do you have the Android emulator installed?

lament portal Apr 27, 2023, 4:22 AM

#

i have android studio, not sure how to use it tho

#

pnpm tauri dev works fine

celest garden Apr 27, 2023, 4:23 AM

#

And that's launching the emulator, not on a physical device?

lament portal Apr 27, 2023, 4:23 AM

#

yeah

#

well just launching on my computer, not emulator

celest garden Apr 27, 2023, 4:23 AM

#

It's an emulator that installed with AndroidStudio that emulates the Android runtime.

#

So long as it's on your computer screen and not a phone screen, then it should have access to your local network. This is a rather strange bug.

#

Do you have a GitHub repo that is public?

lament portal Apr 27, 2023, 4:25 AM

#

yeah but not using mobile tauri

#

im currently just testing on whats given by tauri-create-app alpha

celest garden Apr 27, 2023, 4:25 AM

#

Oh. So this isn't including bevy yet?

lament portal Apr 27, 2023, 4:25 AM

#

this one is using svelte

celest garden Apr 27, 2023, 4:25 AM

#

Just an empty project created by create-tauri-app?

lament portal Apr 27, 2023, 4:25 AM

#

yep

celest garden Apr 27, 2023, 4:29 AM

#

If you visit the IP in a browser, do you see any content?

#

If not, it means the server failed to start for some reason.

lament portal Apr 27, 2023, 4:31 AM

#

using pnpm tauri dev it works on localhost:1420

#

also did pnpm tauri android open, it loaded android studio but idk how to emulate it

celest garden Apr 27, 2023, 4:32 AM

#

lament portal do u know what this means?

If you open a cmd window and run ifconfig, do you see this IP in the list?

#

Uh... ipconfig. Sorry, Windows and Linux have similar commands.

lament portal Apr 27, 2023, 4:33 AM

#

do i need to run pnpm tauri android dev again first?

celest garden Apr 27, 2023, 4:34 AM

#

No, your IP shouldn't change very often on a local network.

lament portal Apr 27, 2023, 4:34 AM

#

yes

celest garden Apr 27, 2023, 4:35 AM

#

I'm trying to make sure that the IP fetched by the Node package internal-ip is one that you've been assigned.

#

So it's not a package bug. Weird that the emulator couldn't connect to it when the dev server is running.

#

What does the beforeDevCommand look like in your tauri.conf.json?

lament portal Apr 27, 2023, 4:38 AM

#

pnpm dev

celest garden Apr 27, 2023, 4:38 AM

#

It should have --hostname $HOST at the end to allow the hostname to change.

lament portal Apr 27, 2023, 4:39 AM

#

do i change it to pnpm dev --hostname $HOST ?

celest garden Apr 27, 2023, 4:39 AM

#

Yes.

celest garden Apr 27, 2023, 4:40 AM

#

lament portal yes

Since the server is running on this IP, it should change the hostname to match and allow the connection.

lament portal Apr 27, 2023, 4:42 AM

#

lament portal do i change it to `pnpm dev --hostname $HOST` ?

gives "CACError: Unknown option --hostname"

#

does this warning mean something?

#

when i run pnpm tauri android dev

#

without --hostname

celest garden Apr 27, 2023, 4:47 AM

#

Oh, you're using Vite, not Next.js, it means that Vite will automatically detect it.

#

Remove the --hostname $HOST again, my mistkae.

lament portal Apr 27, 2023, 4:48 AM

#

i get this after it finishes compiling

celest garden Apr 27, 2023, 4:49 AM

#

Does it normally give you that output?

lament portal Apr 27, 2023, 4:49 AM

#

yeah every time i run it

celest garden Apr 27, 2023, 4:50 AM

#

The mention of "Failed to read DnsConfig" is a little concerning.

#

You definitely ran rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android, right?

lament portal Apr 27, 2023, 4:51 AM

#

yes

celest garden Apr 27, 2023, 4:52 AM

#

Oh... I just spotted the problem. In your vite.config.ts, the port is 1421 but the mobile is expecting 1420.

lament portal Apr 27, 2023, 4:53 AM

#

oh lmao ill try run it again

#

still doesn't work :(

#

btw opening tuari.localhost on my computer doesn't work either

celest garden Apr 27, 2023, 5:01 AM

#

Do you open the IP directly or as tauri.localhost?

lament portal Apr 27, 2023, 5:01 AM

#

tauri.localhost

#

oh

#

wtf

#

i turned off my public firewall and now it worked

#

uhhh

celest garden Apr 27, 2023, 5:02 AM

#

Okay, that's really weird if you've never changed the default settings for it.

lament portal Apr 27, 2023, 5:02 AM

#

do you know how to configure it so i don't need to turn off my firewall?

celest garden Apr 27, 2023, 5:02 AM

#

Apparently the hrm setting in vite.config.ts should be a different port (1421), according to the example in the docs. Not sure why but should probably change it back.

lament portal Apr 27, 2023, 5:02 AM

#

ah ok

celest garden Apr 27, 2023, 5:03 AM

#

Are you using WIndows 10 or 11?

lament portal Apr 27, 2023, 5:03 AM

#

lol this is popping up like every second now

#

windows 10

celest garden Apr 27, 2023, 5:04 AM

#

If you search for Windows Defender Firewall, it should come up with a brick wall and a globe icon.

#

On the left, you should see a Turn Windows Defender Firewall on or off option.

lament portal Apr 27, 2023, 5:05 AM

#

yep

celest garden Apr 27, 2023, 5:05 AM

#

Inside that there will be a Block all incoming connections checkbox which is probably ticked for you.

#

If it's not, I'm not sure what is causing the problem.

lament portal Apr 27, 2023, 5:06 AM

#

celest garden Apr 27, 2023, 5:06 AM

#

Yeah, should look like that. Is that the settings you had already?

lament portal Apr 27, 2023, 5:06 AM

#

yeah

celest garden Apr 27, 2023, 5:07 AM

#

And you never saw a prompt about the app?

lament portal Apr 27, 2023, 5:07 AM

#

i think there was a prompt when i opened android studio about adb.exe

celest garden Apr 27, 2023, 5:08 AM

#

Yeah, that would probably have been it.

#

Did you leave it ticked for public networks?

lament portal Apr 27, 2023, 5:09 AM

#

yeah, have it ticked

celest garden Apr 27, 2023, 5:09 AM

#

Hm... there's two of them?

lament portal Apr 27, 2023, 5:09 AM

#

i turned firewall back on and restarted, its not working again

#

should i maybe tick both adb.exe's?

celest garden Apr 27, 2023, 5:10 AM

#

Check the paths for them first.

#

Click on either one and then Details.

lament portal Apr 27, 2023, 5:11 AM

#

both of them are \appdata\local\android\sdk\platform-tools\adb.exe

celest garden Apr 27, 2023, 5:11 AM

#

That's odd. Try ticking both then.

#

Considering both are ticked for public networks though, it should be allowed through.

lament portal Apr 27, 2023, 5:13 AM

#

ticked both, still doesn't work

celest garden Apr 27, 2023, 5:17 AM

#

If you run Resource Monitor, it should tell you what process is trying to create a network connection.

#

I have no idea what it could be other than NodeJS or adb.exe

lament portal Apr 27, 2023, 5:19 AM

#

celest garden Apr 27, 2023, 5:21 AM

#

The two Java processes are also using the network?

lament portal Apr 27, 2023, 5:21 AM

#

yeah

#

oh adb just spiked a ton

celest garden Apr 27, 2023, 5:22 AM

#

If you go to the Network tab, it should tell you what IPs they're asking for.

#

Under TCP Connections

#

It will have a lot of clutter in there but you would be looking for anything asking for the IP posted earlier.

lament portal Apr 27, 2023, 5:23 AM

#

celest garden Apr 27, 2023, 5:24 AM

#

Loopback is normal and shouldn't be getting blocked. It's more likely to be a different IP.

lament portal Apr 27, 2023, 5:28 AM

#

all of them have a local address of 192.168.5.227 or IPv4 loopback

celest garden Apr 27, 2023, 5:29 AM

#

Any ports you recognise, like 1420 or 1421?

#

Are you running this in a container at all, or is it just bare Windows?

lament portal Apr 27, 2023, 5:31 AM

#

just windows

#

reran tauri android dev, a greyed out node.exe showed local port 1420 for a bit then disappeared

celest garden Apr 27, 2023, 5:32 AM

#

Yeah, that's normal. Things disappear when there's no active connection. Listening Ports is the category below.

lament portal Apr 27, 2023, 5:32 AM

#

ah oki

#

celest garden Apr 27, 2023, 5:33 AM

#

Everything works fine with the firewall off, right?

lament portal Apr 27, 2023, 5:33 AM

#

yep

celest garden Apr 27, 2023, 5:34 AM

#

Hm... I'll try to replicate it on my end because I'm out of ideas on what it could be.

#

Once you whitelist something in the firewall, unless you've got a very angry anti-virus, it shouldn't be an issue.

lament portal Apr 27, 2023, 5:35 AM

#

oh i got it

celest garden Apr 27, 2023, 5:35 AM

#

Anti-virus...?

lament portal Apr 27, 2023, 5:35 AM

#

had to tick both node.js javascript runtimes

celest garden Apr 27, 2023, 5:35 AM

#

Oh.

#

Two runtimes is unusual unless you've got multiple versions installed?

lament portal Apr 27, 2023, 5:37 AM

#

uhh wtf i just ran it again and this popped up

lament portal Apr 27, 2023, 5:38 AM

#

celest garden Two runtimes is unusual unless you've got multiple versions installed?

idk a lot of the apps in here have two

#

both of the nodes point to the same exe

celest garden Apr 27, 2023, 5:39 AM

#

Oh, maybe it's inbound and outbound.

#

Hm... doesn't look like it. Maybe just a weird thing that Windows did during an update or something.

lament portal Apr 27, 2023, 5:42 AM

#

lament portal uhh wtf i just ran it again and this popped up

nvm my phone just disconnected so it emulated instead

#

its all good now

#

tho i still get that wall of warnings

lament portal Apr 27, 2023, 5:42 AM

#

lament portal still doesn't work :(

this

celest garden Apr 27, 2023, 5:43 AM

#

That's probably the debug output from the emulator. Might have been enabled in Tauri to find issues and found it's way into a release version.

lament portal Apr 27, 2023, 5:43 AM

#

hmmm live updates aren't working

#

changing lib.rs recompiles a bunch of stuff and works but changing js files doesn't update on my phone

#

oh uh now it keeps on recompiling even tho nothing changed

#

its fine i think i can figure it out for now, tysm for your help @celest garden !

celest garden Apr 27, 2023, 5:49 AM

#

No problem. I'm glad we figured it out, it was a strange issue.

grand rain Aug 23, 2023, 4:20 PM

#

Hii! I have the same issue. My app cant connect to localhost (on real device). In this thread i didnt find how you solved it. My app works fine on emulated device as well.
"The web page at https://tauri.localhost/ could not be loaded because: net::ERR_CONNECTION_REFUSED"
@lament portal did you fix it after all?

grand rain Aug 23, 2023, 4:21 PM

#

lament portal its taken like 8 m to start 🙃 is this normal?

yes, pretty much

lament portal Aug 23, 2023, 9:05 PM

#

grand rain Hii! I have the same issue. My app cant connect to localhost (on real device). ...

Yeah the issue for mine was that the firewall wasn't set up properly, went to resource monitor to change a bunch of settings until it worked

#

You can check whether the issue is with the firewall by turning it off completely on settings first

grand rain Aug 24, 2023, 4:53 AM

#

lament portal Yeah the issue for mine was that the firewall wasn't set up properly, went to re...

yeah. i mean. U fixed it on your pc. But it should be still failing on your phone, isnt it? At the end you moved over using real device to emulated one and it worked, but it didnt fix the issue with running app on actual device. How did you handle that?

#

at the end of the day we need running app on real device, did release build help?

lament portal Aug 24, 2023, 5:51 AM

#

grand rain yeah. i mean. U fixed it on your pc. But it should be still failing on your phon...

No it fixed it on my phone as well somehow

#

I was never using an emulated one

grand rain Aug 24, 2023, 6:24 AM

#

OMG

#

YooooHoooooo

#

i got it. portmaster was blocking my pc server.
I thoutght it transfers all files to device. But instead pc starting to be a server

#

@lament portal Thank you alot!
