cargo-mobile2 Error running default wry template

Describe the bug When I generate a wry template using the latest cargo-mobile2 (or version 0.5.1 as suggested here : https://github.com/tauri-apps/cargo-mobile2/issues/210#issuecomment-1728503050), I get this error : e: /home/riccardo/dioxus-mobile-test/gen/android/app/src/main/kotlin/com/example/dioxus_mobile_test/MainActivity.kt: (3, 22): Unresolved reference: WryActivity

Steps To Reproduce

Setup Android SDK, NDK...
Add Rust targets
Create a new Rust project and cd into it

:thinking: I ran "cargo android apk build" and then "cargo android run" and it worked :thinking: I think I also reinstalled the cargo-mobile2 CLI just after cargo mobile init :thinking: I got an error few seconds after launching but it works :thinking:

If you have enabled significant logging, look into using the -G option to increase log buffer sizes.

But when I create a new blank wry project, cargo mobile init and cargo android run I get the same error :thinking: :

e: /home/riccardo/dioxus-test/gen/android/app/src/main/kotlin/com/example/dioxus_test/MainActivity.kt: (3, 22): Unresolved reference: WryActivity

And running cargo android apk build doesn't work neither :thinking:

Dec 29 '23 09:12 crat1985

For a project that compiles, gen/android/app/src/main/kotlin/com/example/truc/ contains the following files :

Ipc.kt                  RustWebChromeClient.kt
Logger.kt               RustWebViewClient.kt
MainActivity.kt         RustWebView.kt
PermissionHelper.kt     WryActivity.kt
proguard-wry.pro

But for the other project, gen/android/app/src/main/kotlin/org/slt/org only contains MainActivity.kt

Dec 29 '23 09:12 crat1985

It seems like cargo-mobile2 doesn't generate some files needed like WryActivity.kt :thinking:

I can reproduce the issue on macOS. I tested a few different versions of wry with the wry template. The default wry version 0.28 does work for me with the mobile template. Any version after 0.34.0 fails to link to WryActivity. I followed these instructions when updating wry. Here is the repo with the reproduction. To run the project I used these commands:

cargo android build
cargo android open
// Start an pixel 7 pro API 33 emulator
cargo android run

Thanks I'll try that asap !

Unfortunately I get the same error Here are the things I did :

export JAVA_HOME="/usr/lib/jvm/java-17-openjdk"

instead of

export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

otherwise it would cause a Kotlin error then

wget https://dl.google.com/android/repository/commandlinetools-linux-8512546_latest.zip -o cmdline-tools.zip

unzip cmdline-tools.zip
cd cmdline-tools
mkdir latest
mv bin latest/
mv lib latest/
mv NOTICE.txt latest/
mv source.properties latest/
cd ..
mkdir ~/.android
mv cmdline-tools ~/.android

then

export ANDROID_HOME="$HOME/.android"
~/.android/cmdline-tools/latest/bin/sdkmanager "platforms;android-33" "platform-tools" "ndk;25.0.8775105" "build-tools;33.0.0"

then

export JAVA_HOME="/usr/lib/jvm/java-17-openjdk"
export ANDROID_HOME="$HOME/.android"
export NDK_HOME="$ANDROID_HOME/ndk/25.0.8775105"

then

rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android

then

cargo install --git  https://github.com/tauri-apps/cargo-mobile2

then

mkdir hello
cd hello
cargo mobile init

then

cargo android run

and then I get this error

In fact I didn't follow the [https://github.com/ealmloff/docsite/blob/7f57a13d28e4d5d47c6fd9e3022fb1d2989aee1b/docs-src/0.4/en/getting_started/mobile.md](Mobile App guide) PR you opened :sweat_smile: I'll try that asap :sweat_smile:

Sorry for the long delay, I have updated the wry template in #281

Also noticed that we can't actually do a cargo mobile init on existing tauri apps right? I was expecting it to update existing tauri app config though at least to match because if we do have existing desktop app it won't be easily migrated into the mobile version?
