Recommended to install Waydroid in a brand new Ubuntu 25.04 install. Waydroid needs a custom linux kernel. Actually just needs latest kernel for WSL2 with just these changes before compiling:
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder"

This write-up is about the STM32 cryptographic firmware library X-CUBE-CRYPTOLIB, also known as the Cortex-M Optimized Crypto Stack (CMOX). It is a cryptographic library developed by STMicroelectronics (ST) for their series of STM32 processors, which are based on the ARM Cortex-M family.
Hardware features vary across different STM32 processors. Because CRC checksums are widely used in embedded systems, most (if not all) STM32 processors feature a hardware CRC unit that is supposed to accelerate CRC computations.
Interestingly, on the page "Getting started with the Cryptographic Library", ST claims:
If you're looking to develop an Android app you might be led to Android Studio. It's the IDE recommended and developed by Google for the express purpose of Android development. It does what it needs to, but if you look at the system requirements you will see some alarming numbers. If you're using an older system, or simply don't want to use AndroidStudio, this is the guide for you.
We won't be using many apt packages due to permissions issues and incompatible versions. That being said:
$ sudo apt install openjdk-17-jdk sdkmanager kotlin

In the kernel source directory, run
make O=/tmp/linux/arm64 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j60 defconfig allThen create an Alpine aarch64 image following https://hackmd.io/@starnight/Run_Alpine_on_QEMU_aarch64_Virtual_Machine
wget https://dl-cdn.alpinelinux.org/alpine/latest-stable/releases/aarch64/netboot/vmlinuz-lts https://dl-cdn.alpinelinux.org/alpine/latest-stable/releases/aarch64/netboot/config-lts
This is for those of you who want or need to use Windows but prefer to have everything dev-related (including GUI applications like IDEs) running inside WSL2. Unfortunately, if you're developing for Android, it's impossible[^citation-needed] to run virtual devices in WSL2.
