Build instructions?

[Enovale]

In the readme you state that build instructions will come "soon". How soon, exactly? I dont want to be like "release wen" but I also dont want you up and dying on us again before you can post instructions, also, is it possible to modify the current build to build it ourselves? I 'm trying to get it to work anyway but i see a lot of hard coded directories and obviously theres no explanation of anything.

[zhuowei]

@ElijahZAwesome OK, to be completely honest I only released this since other people decompiled the app and got that to work anyways. So I figured having the original source as reference might already be helpful.

If I remember correctly, the build steps are:

build glshim (ndk-build)
build lwjgl (ant compile, then go to platform_build/android_wrapper and ndk-build)
copy the libraries manually

go to Boardwalk

./predex-compile.sh, ./predex-run.sh, ./predex-deploy.sh
ndk-build
ant clean release

but I haven't built this in years and I would also need to figure this out again.

[Enovale]

That's insightful.. However I kind of already pieced that together. the thing is, I can't figure out how to build glshim, and idk what you mean by ndk-build (im new to android devving)

[zhuowei]

@ElijahZAwesome

You'll need to install the Android NDK to build this, since it contains C++ code.

https://developer.android.com/ndk

the glShim shim I uploaded seems to only have the build script for Boardwalk 2.0; I'm going to look for the 1.0 build script; give me a sec

[Enovale]

I already have Android Studio installed, and I believe I installed the NDK with it. I'm not completely oblivious to Android Devving, I have modified apps before, I just don't know the basics

[zhuowei]

@ElijahZAwesome Boardwalk predates Android Studio; I tried to get 2.0 building in Android Studio, but that didn't work, so I never added those changes back to 1.0.

Thus, the 1.0 code still uses the ant build system.

You will need an older version of the Android SDK.

This is everything I have installed right now: I doubt you'll need all of these though.

• SDK manager 25.2.5
• SDK tools 25.2.5
• SDK Platform-tools 23.1
• SDK build-tools 27.0.3, 23.0.3, 21.1.2, 20, and 17
• Android 8.1, 6.0, 5.0.1, 4.4, 4.3.1, 4.2.2, 4.0.3, 2.3.3 SDK platforms
• Google Play Services 29
• Google Repository 24
• Android support library 23.1.1

I could, like, zip up my entire Android SDK folder and upload it, but that's probably overkill...

As long as you can build Android apps using ant it should probably work.

You will also want a version of the Android NDK: I'm using Android NDK r10c. A newer version would probably work.

For the libraries it needs:

• aFileChooser is https://github.com/zhuowei/aFileChooser
• makeshift and openal-soft will be uploaded to BoardwalkApp
• update: makeshift is in BoardwalkApp now, and openal-soft is https://github.com/zhuowei/openal-soft
• gms/gmsads is the Google Play Services Ant package with everything but the Ads part removed. I'll upload this too.
• lwjgl/platform_build/android_wrapper is the boardwalk-lwjgl repo.

I'm trying to figure this out myself, so sorry about this!

[Enovale]

Honestly I would really like a zipped SDK, just for the ease of access. Also, right now, i'm trying to build one of the dependencies (lwjgl) to work and getting errors about not having "lib/tools.jar" in my JDK. Also glshim wont cmake properly or something, it doesn't seem to be making a makefile for me to use.

[zhuowei]

Don't cmake it: I'm uploading my old build script right now.

[Enovale]

for 1.0 or 2.0? I was hoping to build 2.0 because of the dang nougat bug

[zhuowei]

Oh, 2.0: ... I don't even have graphics working on that, so you might not actually need glshim... Give me a sec. I think I built that using the 1.x build script, not the 1.9 build script.

You don't need the Ant stuff for 2.0, but you still need the Android NDK.

Edit: run ndk-build in https://github.com/BoardwalkApp/boardwalk-glshim/tree/master/build/android

[Enovale]

The more and more I work on this the more i'm realizing I should use linux instead of windows rofl

Ubuntu subsystem yayyy

[zhuowei]

@ElijahZAwesome I'm on Ubuntu 14.04 (amd64) for what it's worth, although I think it would build on newer Ubuntu.

Anyways, for 2.0: the build process is even crazier, because I was trying to get mods working.

• You might need Android NDK r15c (which supports Android Studio) as well as r10c (which doesn't support Android Studio, but I know works with glshim and lwjgl)

• build OpenJDK. https://github.com/BoardwalkApp/boardwalk2-openjdk-build (that's going to take an hour; start that one first.)

• build boardwalk2-lwjgl3

• (not sure what else?)

• run the repacklwjgl3 and lwjgloverride scripts in Boardwalk. (I don't have these uploaded yet: give me asec.)

• then build Boardwalk with Android Studio.

• run it: you'll get a blank screen and a crash somewhere in lwjgl. yay?

[Enovale]

So 2.0 isn't functional yet? Damn. So there's still no way to play on v>Nougat without just finishing 2.0?

[zhuowei]

@ElijahZAwesome I know @khanhduytran0 has an app that includes a decompiled version of Boardwalk modified so it works on Nougat and Oreo - see #304 .

I think they removed the download link as I told them that including Boardwalk a the time infringes on Boardwalk's code. I open sourced Boardwalk so they can hopefully upload their app again (and then people won't ask me to update Boardwalk anymore)...

Anyways, even that app still won't support mods, which is why I'm trying to get 2.0 working instead of fixing 1.x

[Enovale]

Gotcha. If there's any way I can help (Maybe explain how this mess of code works sometime?) I would be glad to. It doesn't look like khan's source is anywhere, so I guess I just have to wait?

[zhuowei]

@ElijahZAwesome

Mess of code basically has five parts, each part fixing one compat issue:

Minecraft renders graphics using LWJGL and desktop OpenGL.

• LWJGL is patched to run on Android and to use glshim as its OpenGL library
• glshim (which is completely unmodified from ptitSeb's glshim version that worked on Minecraft for non-Android devices) converts desktop OpenGL to mobile OpenGL ES 1.1

Minecraft plays sound using OpenAL.

• thankfully OpenAL already works on Android.

Minecraft uses Desktop Java instead of Android's Dalvik.

• Android SDK's dx tool is run on the phone itself to convert Minecraft's .jar to Dalvik format.
  • this doesn't work on Nougat and Oreo, so I think khan's app just does this ahead of time. This does mean that it can only run one version of Minecraft at a time.
• other libraries used by Minecraft is converted ahead of time (using the predex* scripts)

Minecraft loads PNG files using Java AWT, which isn't available on Android.

• Boardwalk uses jarjar to redirect these calls to Boardwalk's makeshift library, which implements these APIs using Android's image loader

Finally, the Minecraft launcher's login screen doesn't work on Android.

• Boardwalk implements Minecraft.net logins.

So that's basically the five parts of Boardwalk 1.x.

Boardwalk 2.0 has two additional goals:

Mods won't run on Android's Dalvik: converting them like Minecraft won't work, since Modloader needs a real Java virtual machine

• Boardwalk 2.0 actually uses the real Java virtual machine, which Oracle ported to Android in 2016.
• it doesn't work well though.

Minecraft 1.13 and above doesn't use lwjgl - they switched to lwjgl3

• Boardwalk 2.0 tries to implement this, but fails - immediately crashes.

So that's a super high level summary of what Boardwalk does.

Also, check your email.

[Enovale]

Thanks a lot for that (and the email). Idk, I might look into 2.0 if/when i get it built, but like i said im not super experienced in android so it will take a while (or at least until you figure it out yourself)

[zhuowei]

@ElijahZAwesome Again, sorry about this. If I ever get 2.0 working, I'll definitely make sure it's buildable with one command instead of this craziness.

[Enovale]

How long do you plan to support this @zhuowei ? Or are you going to get thanos snapped for another 3 years :P

[zhuowei]

@ElijahZAwesome Unfortunately, I really don't have a plan for this. One of the reasons why I uploaded the source right now is that I'm not sure how much time I'll have later this year to work on projects. I'll let you know once I figure this out. I'm so sorry about this.

(Also, Endgame spoilers! nooooo ;) )

[Enovale]

I kind of figured as much. Well no matter how much time you put into it, I'm glad you open sourced it. I've been waiting a very long time for this lol.

(Never watched endgame or infinity war :P)

[lerepex]

@zhuowei @ElijahZAwesome
The version from @khanhduytran0 ist still available at Aptoide I just downloaded it there. Here is the link:
https://net-minecraft-kdt.en.aptoide.com/

Edit: Can confirm that it's the right one and that it is working fine even on Android 9

[Vretox]

The app was probably deleted from Aptoide (or I just can't download it). At least I found a site where you can download it. Link ---> https://android-apk.org/net.minecraft.kdt/42357093-net-minecraft-kdt/

1.9 works perfectly with 7 render distance on Poco F1 (around 30-40 fps)

[GalaxinTM]

But it does not have all of the versions, 1. 1, 1.7.2, 1.7.10, 1.8, 1.9

[KorewaLidesu]

android-apk.org had been removed too
