Installing dependencies

Node.js, JDK, Android Studio

you can install node.js via chocolatey, which is a package manager for windows.

it is recommended to use an LTS version of node.js, if you want to switch different version of node.js, you might need to install a node via nvm-windows, which is a node version manager for windows.

you need to also require the java SE development kit(JDK), which can be installed via chocolatey as well.

To do that, open Android Studio, click on the "More Actions" button and select "SDK Manager".

Then select the "SDK Platform" tab from within the Android SDK, then check the box to the next "Show Package Details" in the bottom right corner. and make sure inside Android 12.0 (S) below items are checked inside the "SDK Platform" tab.

Then "click" on the OK button to proceed next SDK Tools Tabs.

next, select the "SDK Tools" tab and check the box next to "Show Package Details" here as well. then make sure that 31.0.0 is selected.

Finally, click "Apply" to download and install the Android SDK and related build tools.
