RPG Maker MV to Android exporter tool by MBTY

Hi bros. My native language is russian, so i`m sorry if text below will strange for you :)
I spent many time to find a solution how to compile Android-APK-file without installing JRE, JDK, Aapt, Android SDK, Python, nodeJS and all this stuff in to Windows for only one purpose. I mean portable solution.
I googled html5apkbuilder (incomplete), official guide (need TOO many soft to install), and couple of tools which is wasn`t satisfy me by some reason (not only me if they are not popular).



After three days of working i made a package of: minimized portable java environment + APK recompilator + application sign key creator + several necessary tools to create an android application + batch script for simplifying whole process.

I tested this package on CLEAN Windows: XP(x86), 7(x64), 10 (x64) without any sign of JAVA SDK. And it`s work!

So here is screenshot:

I think it`s totally obvious what you can do here ;)

Application sign key must be created at least once (of course you can recreate it as many as you want). So before your first APK making you should make a sign key - it`s easy. Just answer a few questions in script (Name, City etc.)

Next you should place your "www" folder in "!RPGMV" folder.
Also you can replace an icon there (!RPGMV\icon.png). Icon can be any resolution - script will generate the right one(s). But it must be PNG picture.
That`s it!

Now you can choose 1st option and you`ll see this:


After filling this form (and press enter) you must wait about a minute.
You`ll get theese files:
0_app.unsigned.apk - totally will not install but you can sign it manually (needs for devs)
1_app.signed.apk - signed working application
2_app.signed.aligned.apk - signed working optimized application - this is your file!

Also, as bonus, script can make 3_app.signed.max-optimized.apk and 4_app.signed.optimized.aligned.apk - this is application with insane optimization but this optimization can long a hours, so you can wait or just close script window on this step. My apk (from video) without optimization weight is about 50Mb and 40Mb after it.

P.S. i`m working with RPGMMV 1.5.1 and Android 6.0.1. Regards!

Hi MBTY, can you make a video showing how to use this?

Hello, my friend!
I hope i made good enough video. My phone screen record appliction can not to record sound, but game is playing sound and music vell.

@MBTY I tried this and followed it step for step, but I only got the first file (the uninstallable apk), but not the other two. Is it because my game is over 500MB without scrubbing it? Using Windows 7 if that helps.

Hello! You are right. The solution is to add x64 portable java components and achieve possibility to compile and sign APK up to 4 GB size. But your Windows must be x64 ofcourse. Whole tool folder will expand about +40mb when extracted. Just wait couple of hours please.

My Windows 7 PC is x86 (32-bit)... Sigh, back to searching for a x86 compatible method... RIP my dreams...

I really had high hopes for this... Maybe my other PC is x64 (if not, *world's tiniest violin plays sad music in the background*...)

But any Windows x86 (Vista, 7, 8, 8.1, 10) can`t give to any process more than 2GB of RAM (Javax86 can`t take more than 1Gb). I`m afraid you need to reinstall windows.
New version in topic. It`s automaticly detects x86/x64 OS and set limit of RAM to 1024 Mb or 4096Mb.
I tested x64 version. It can make an APK more than 1.5 Gb.

You said
, correct?

Does that mean I can use something like this (https://shatter-box.com/knowledgebase/android-apk-signing-tool-apk-signer/) to change 0_app.unsigned.apk into a signed installable apk or am I missing something else?

It does work, just need to slim the project size down some in the future.

This has now become a godsend for the community.

I`m working on v4 of this tool. JtheDuelist suggested nice method of APK-signing. It`s uses about 20-30 Mb of RAM no matter how big is APK file.
So new version no need to include x64 java components anymore! :)
Also made new video (still can`t capture sound on smartphone, sorry)
v4 is now on java components optimizing stage - longest process (about 2 hours)
Hope JtheDuelist will test it with positive results soon

Will test in the morning.

If you want screen recording with sound recording, give the apps DU Screen Recorder or Mobizen a try.

v4 uploaded! Just tested compilation of 2 GB project on Windows XP with 1 Gb RAM in PC. Successful.

It works

But when I go to test the game on my Android device, I can hear the audio, but everything is black....

EDIT: I wasn't using the optimization feature... Will try it again with optimization.

EDIT: Even after optimization, still blacks screens with audio playing.

Can you share your project or apk file?

Works perfect for me, this is truly great. Thank you so much for that!

Now we just need an app file that pulls the resource from a server so you can bypass the 100mb limits.

Oh. I have no idea how to split big apk to small APK (< 100 mb) and resource obb file.

Awe dang. It’s worth a shot haha.

Good news everyone! I think i understand how to create OBB files. (Expansion files for publication on google play)
Bad news everyone.. i`m afraid we need some kind of code or plugin to include in our MV projects to read this OBB files. I can not realize this on my own.
