android platform fails to bundle on nixos

[JJJHolscher]

Problem

dx build --platform android compiles but does not bundle.

  59.314s  INFO Bundling app...

Steps To Reproduce

Cargo.toml:

[package]
name = "my_app"
version = "0.1.0"
edition = "2021"

[dependencies]
dioxus = { version = "0.6.2", features = ["desktop", "mobile", "macro"] }

[profile]

[profile.wasm-dev]
inherits = "dev"
opt-level = 1

[profile.server-dev]
inherits = "dev"

[profile.android-dev]
inherits = "dev"

src/main.rs:

use dioxus::prelude::*;

fn minimal() -> Element {
    rsx!{ "hello world" }
}

fn main() 
{
    dioxus::launch(minimal);
}

shell.nix:

{
  # pkgs ? import <nixpkgs> { },
}:
let
  pkgs = import (fetchTarball("channel:nixpkgs-unstable")) {};

  overrides = (builtins.fromTOML (builtins.readFile ./rust-toolchain.toml));

  buildToolsVersion = "30.0.3";
  androidComposition = pkgs.androidenv.composeAndroidPackages {
    cmdLineToolsVersion = "8.0";
    toolsVersion = "26.1.1";
    platformToolsVersion = "35.0.2";
    buildToolsVersions = [ buildToolsVersion ];
    includeEmulator = true;
    emulatorVersion = "35.4.6";
    platformVersions = [ "28" "29" "30" ];
    includeSources = false;
    includeSystemImages = false;
    systemImageTypes = [ "google_apis_playstore" ];
    abiVersions = [ "armeabi-v7a" "arm64-v8a" ];
    cmakeVersions = [ "3.10.2" ];
    includeNDK = true;
    ndkVersions = ["22.0.7026061"];
    useGoogleAPIs = false;
    useGoogleTVAddOns = false;
    includeExtras = [
      "extras;google;gcm"
    ];
  };
  ANDROID_HOME = "${androidComposition.androidsdk}/libexec/android-sdk";
in
pkgs.callPackage (
  {
    atkmm,
    cairo,
    gcc,
    gdk-pixbuf,
    glib,
    gtk3,
    mkShell,
    openssl,
    pango,
    pkg-config,
    rustup,
    rustPlatform,
    stdenv,
    webkitgtk_4_1,  # for javascriptcoregtk-rs-sys
    xdotool,        # for libxdo
  }:
  mkShell {
    strictDeps = true;
    nativeBuildInputs = [
      gcc
      openssl
      pkg-config
      rustup
      rustPlatform.bindgenHook
    ];
    buildInputs = [
      atkmm
      cairo
      gdk-pixbuf
      glib
      gtk3
      pango
      webkitgtk_4_1
      xdotool
    ];
    GDK_BACKEND = "x11";  # NVIDIA might disagree otherwise.
    PKG_CONFIG_PATH = "${pkgs.openssl.dev}/lib/pkgconfig";
    RUSTC_VERSION = overrides.toolchain.channel;
    WEBKIT_DISABLE_DMABUF_RENDERER = 1;  # Again NVIDIA things.

    ANDROID_HOME = ANDROID_HOME;
    ANDROID_NDK_ROOT = "${ANDROID_HOME}/ndk-bundle";
    NDK_HOME = "${ANDROID_HOME}/ndk/22.0.7026061";
    # Use the same buildToolsVersion here
    GRADLE_OPTS = "-Dorg.gradle.project.android.aapt2FromMavenOverride=${ANDROID_HOME}/build-tools/${buildToolsVersion}/aapt2";

    # https://github.com/rust-lang/rust-bindgen#environment-variables
    shellHook = ''
      export PATH="''${CARGO_HOME:-~/.cargo}/bin":"$PATH"
      export PATH="''${RUSTUP_HOME:-~/.rustup}/toolchains/$RUSTC_VERSION-${stdenv.hostPlatform.rust.rustcTarget}/bin":"$PATH"
     '';
  }
) { }

Note here that I did not set JAVA_HOME. I'm not sure what to set it to and I do not know whether that is the source of my trouble.
This shell.nix has seen various iterations. One where I use https://tadfisher.github.io/android-nixpkgs instead of pkgs.androidenv and one where I tried to just use android-studio, but could not get dioxus to recognize the project (but that might just be a me-problem).

Finally, the commands I then run is

nix-shell
rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android
rustup default nightly
cargo install dioxus-cli
dx build --platform android

Expected behavior

No failure, but a bundled .apk (I think, I've never gotten it to bundle)

Environment:

• Dioxus version: 0.6.2
• Rust version: 1.87.0-nightly
• OS info: NixOS 24.11 (shell.nix was used for 24.11 and unstable)
• App platform: mobile
• dioxus-cli version: 0.6.3 (crates) and main.

Questionnaire

I'm interested in fixing this myself but don't know where to start.
