So, I choose to use react-native cli over Expo to make my app. As I was setting up, the biggest issue I encountered was the CMake error and I was lost, but here are the sequence of solutions that I tried which resolved my problem!

Solutions I Tried

Install and Set Up Android Studio

• Open Android Studio and go to SDK Manager.
• Download the latest Android API, SDK Build-Tools, and NDK. > Update environment variables to include paths to Command-Line Tools and Platform Tools.

Ensure that the environment variables are updated to include the latest paths for Command-Line Tools and Platform Tools.

Simplify Java Environment Variables

• Ensure only one version of Java (e.g., Java 17 OpenJDK) is set in environment variables.

Locate and Edit CMakeLists.txt

• Locate CMakeLists.txt at:

D:\<Project-Name>\node_modules\react-native\ReactAndroid\cmake-utils\default-app-setup\

• Update its content to:

cmake_minimum_required(VERSION 3.13)

# Define the library name here.
project(appmodules)

# Check if the host system is Windows
if(CMAKE_HOST_WIN32)
  # Replace backslashes in paths to forward slashes
  string(REPLACE "\\" "/" REACT_ANDROID_DIR ${REACT_ANDROID_DIR})
endif()

# Include the ReactNative-application.cmake file
include(${REACT_ANDROID_DIR}/cmake-utils/ReactNative-application.cmake)
