In the command window, navigate to the folder where you're going to make the project. This should be something unique to your app and it's probably best to start with an empty folder. My directory probably won't match up with yours, but here's an example of how to get there:
Note that 'cd' is the command to change directories; you have to type that before the desired location if you want to move to it. If you need to go up a folder you can just type:
Once you're where you want to be, you're only a single command from having your very own Cordova project:
Folder is the name of the folder you want your Android app to be built from and in. Identifier is the name the system will use for your app, usually something like "com.RPGMaker.MyGame." Lastly, name is the name of your app that other humans will generally see. As an example, you could type:
That'll make a folder called GameFolder, it'll give your project the ID com.rmmz.mygame, and it'll make the official name of your app MyGame.

In the command prompt, navigate to your Cordova project's base folder (so if you used the above setup, you'd type cd GameFolder) and then type in:
You can also add others with the same format; type in the following to see what's installed and what's available:

You might already have the Java runtime environment, but we're looking for the JDK. Assuming you don't have it (the requirements check should let you know), cruise on over to https://www.oracle.com/java/technologies/downloads/archive/ and get the development kit appropriate to your pc (so x64 if you're running 64-bit Windows, x86 for 32-bit) and your version of Cordova. As of this update, Cordova 12 is the most current version, which supports up to Java JDK 11. Anyway, install that puppy and move on. Make sure you note the directory you install it to, though; you'll need that next.

To do this, you need to get into System Properties, which should be found in the System window. Go to Control Panel > System and Security > System or just press the Windows+Pause/Break keys together. However you get there, look for a link for "Advanced system settings." You could also just type "environment variables" in the Windows search bar; the first option should be from your control panel, which is what you need.

Now that you (hopefully) have your System Properties window, click the Advanced tab and then click "Environment Variables." Under User variables select Path and click on edit. It's possible you won't have Path listed there; in that case, click the New button and put the Variable name as "Path" (no quotes). That should get us all caught up to the same point.

In the Edit environment variable window, hit new and type in the location of you JDK install (you can just copy and paste from the explorer address bar). If you used the default settings, it should look something like this:
With that done, click okay, and look below System variables for JAVA_HOME. If it's not there, make it (the same way you would have with Path above), then edit it to include...the same thing! This time, leave off the \bin directory from the end. It'll probably look like this:
We're finally done with this step. Click OK until you run out of OKs. Go ahead and open that command prompt again and we'll make sure it's working. Type in:
Did you get a version number? If so, go on to the next step. If not...you messed something up. Sorry about that. Try again. Note that if you left the command prompt open between installs, you'll likely have to exit it and open a new instance to get the new stuff to show.

You've got to be sick of the installations by now; I completely feel that. We're close, though, I promise. You can get Android Studio here: https://developer.android.com/studio. You can also just get the SDK tools from that website if you don't want the whole studio program; the process is mostly the same, but I typically go for the full thing, since it's useful for other things and simplifies the process. I'll assume you're using Android Studio going forward. Run the application once to get everything set up -- it'll want to download some stuff and configure itself for use.

Once it's all set up, click 'more actions' from the starting screen (in Android Studio "Flamingo," which is the most current as of writing this), then select "SDK Manager" from the drop down. You need a few things here:

In the "SDK Platforms" tab, you'll need to install 'Android 13.0 Tiramasu' (or whatever version you'd like to build for; API 33 is the highest supported by Cordova 12).

In the "SDK Tools" tab, you'll first need to uncheck 'Hide Obsolete Packages' and check 'Show Package Details.' Under "Android SDK Build-Tools 34," install 33.0.2. Then scroll down until you see "Android SDK Command-line Tools (latest)" and "Android SDK Platform-Tools." Install all of those, and optionally "Android Emulator."
If you've got a different version of Cordova, check out this page to see which Android versions are supported: https://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html

Go to that same System Properties window where we added our last paths. We're doing basically the same thing again, if you hadn't guessed. Under User variables, select Path and click Edit. This time you'll be adding the directories for tools, command line tools, build tools, and platform tools. If you chose to install the emulator, you'll also need a path for it. Those might look something like this:
Then again, it might not; these directories are prone to change between versions, so if you can't find them, check out this documentation page: https://developer.android.com/studio/command-line/sdkmanager.html.

That's all for User Variables; now go down to System variables. This time we're looking for ANDROID_SDK_ROOT, which you'll probably have to make. Click new, type ANDROID_SDK_ROOT into the name field, and enter the SDK directory into the Variable value. This is probably just going to be the same as the locations you used above, minus that last subfolder, making something like this:
Adding ANDROID_HOME should actually do and point to the same thing as ANDROID_SDK_ROOT, so you shouldn't need it, but it won't hurt to specify that as well with the same folder location used above.
Click OK a couple times when you're done. As always, we want to test, so open the command prompt and type in the following to see if you get a version number:
Got a number? Great. No number? Less great; check your paths for typos and try again.

That means another download first, but don't fret; the end is nigh! Here's the link to get Gradle: https://gradle.org/install/ You'll get the option for binary or complete. Get the one you like (I typically suggest not getting complete; you can always look up documentation online), then extract the files to C:\Gradle (or whatever letter your drive is).

You should be good at this part by now. Find your Environment Variables window again, select "Path" under System Variables and hit Edit. Add a new line and put in the path for gradle's \bin directory. It'll probably be something close to this:
That's it for gradle, but you should probably test and make sure it's working. In a new command prompt window type in:
You should get a version number, just like the previous steps. If you didn't, go back and check for errors.

This part is simple, but you want to make sure everything is where it should be before you move on. Type this into the command prompt while in your Cordova folder:
That should return as installed on all points, with no more of those pesky yellow letters to tell you that something's not working. If you're still getting those pesky yellow letters, go through the above steps again and look for any errors/mistakes/typos/etc.

Again, I'm not really writing an icon tutorial, so I'm just going to touch this briefly. You'll need to make a different icon for each 'density,' put them all in that same res folder I mentioned above, and add something like the following to config.xml instead of what's listed for single icons:
UPDATE: This is optional, but I'd strongly suggest it for projects using API 33 (highest currently supported) or newer - Adroid now supports "monochrome" icons, and not including an option will make your otherwise nice adaptive icons less adaptive. All you need is a grayscale version of the same icons (one for each size - I know that's a lot of images) and include them with the 'monochrome' attribute. The updated version will look like this:
If you need help making the icon files, there are tons of good tools online to convert images to icons, but I'm not going to dive into the specifics of how each is different from the other. Good luck!

This is relatively new, and I don't really want to walk through the process for this guide, but they're a thing now. If you'd like to include one (and you probably will, or your game will open to the Cordova logo), a good place to start learning what to do is the official Android Developers website.

The basic launch page the Maker spits out for your game is...well, pretty basic. Honestly, that's almost always fine, but you might want to consider restricting how the image is scaled and what the area outside of your game window could look like. In the <head> element, I use something like this:
As for the background (the black area that might show to either side of your game), you can change the background color or add an image as attributes of the <body> element. For example, you could have this:
