Hello Guys,
I’m starting to convert my JME3 based game engine (www.scenemax3d.com) to Android. I’m using Android Studio and would like to add JME implementations to the gradle build file So…
Can anyone point me to a gradle build script for Android JME application with support for Minie physics and GLTF loader? Also did anyone tried to run sgold’s JME-Vehicles and SkyControl on Android devices ?
Thanks a lot!
Check this :-
& this one :
Yes, Minie works on the first example above, but I am not very sure about the GITF loader, if it’s loading gITF files without converting j3o, then it also works fine out of the box, but you need to place assets inside Android asset folder…
About Jme-Vehicles, i have started working on android version of it, it works after removing most of Lemur PropertyPanels & TabBar Menus, i cannot remember now what was that problem that caused me to do this, anyway i have plans to build a new HUD using android views… with high performance binding to Android Sensors, which already made a good success as of demoApp linked above…but i haven’t released it on git yet !
NB : it wasn’t sgold’s version that i have tried on android, it was jayFella’s…(old version)
EDIT : i was to upload new android examples for jme3.4.0, but there was some disturbances with git & my network was limited, so those are the very simple examples if you want :
Covered AndroidHarness, FragmentHarness, JmeSurfaceView, Jme~Android native UI (Android Views).
Thanks a lot Pavel. I will take a look
Continue with the Android porting…
I have problem with some dependencies:
in the report below we see that org.jmonkeyengine:jme3-lwjgl:3.3.2-stable and com.github.stephengold:MaVehicles:0.6.0 are dependent on org.jmonkeyengine:jme3-desktop
Therefore I cannot use them in the Android project.
Question for @sgold is it possible to avoid the desktop dependency for the MaVehicle lib? it is because of using the com.atr:jme-ttf:2.2.2
And @Pavl_G how do you include org.jmonkeyengine:jme3-lwjgl:3.3.2-stable in your gradle if it depends on org.jmonkeyengine:jme3-desktop?

| \--- org.jmonkeyengine:jme3-core:3.3.2-stable
Edit: I tried excluding jme3-desktop in the gradle script but it didnt help…
implementation ("org.jmonkeyengine:jme3-lwjgl:3.3.2-stable") {
exclude group: 'org.jmonkeyengine:jme3-desktop:3.3.2-stable'
}
implementation group: 'commons-io', name: 'commons-io', version: '2.0.1'
implementation ('com.github.stephengold:MaVehicles:0.6.0') {
exclude group: 'org.jmonkeyengine:jme3-desktop:3.3.2-stable'
}
Try excluding from all the configurations you use :
Works!!! Thank you!
As you can see from the graph, the dependancy of MaVehicles:0.6.0 on jme3-desktop is indirect (by way of jme-ttf) and therefore an issue for @Tryder to address.
As for lwjgl depending on desktop… lwjgl is a desktop renderer.
…I don’t do android development but I was 99% sure that android apps did not use lwjgl.
Indeed it seems to have its own JME renderer and everything: jmonkeyengine/AndroidGL.java at master · jMonkeyEngine/jmonkeyengine · GitHub
That’s true…but other dependencies may include it implicitly.
Pavel, I saw that lwjgl is added explicitly in your demo app (Superior-Extended-Engine/build.gradle at master · Scrappers-glitch/Superior-Extended-Engine · GitHub)
That’s why I thought it was important. I will remove it from my script and check…
They shouldn’t. Unless you mean non-JME libraries that have messed up their dependencies. That we can’t control except to push back on the author.
Only applications need to depend on a rendering implementation.
Yes, it is wrong & should be removed…, thanks for reminding me
EDIT: I have removed unnecessary dependencies…
Honestly, I really don’t see why I need to be bending over backward here. The fact is your government has made several attempts to assassinate me. To my face you’ll praise my works and ask for more, yet behind my back hire a bunch of hitmen to kill me.
You bought the poison. You bought the guns. You paid their salary. You voted for the people who hired them and gave them the orders.
The source code is on my site. The source code is on github. Download it. Fork it. Fix it up. Whatever, but don’t expect me to do you any favors. This is bullshit.
Sorry to disturb you. I’ll fork the repo, then.
Truely, this has been an eye opening experience.
What are you talking about? Who is trying to kill you?
@Pavl_G did you manage to debug your apps using an emulator or just a physical device?

Here’s a fork of jme-ttf that doesn’t depend on jme3-desktop:
and here’s the latest release:
repositories {
mavenCentral()
}
dependencies {
implementation 'com.github.stephengold:jme-ttf:2.2.3'
}
and here’s a release of MaVehicles that uses jme-ttf v2.2.3:
repositories {
mavenCentral()
}
dependencies {
implementation 'com.github.stephengold:MaVehicles:0.6.1+for33'

AMAZING Stephen!! I can’t wait seeing Jme-Vehicles running on Android devices 
Thanks a lot!
Yeh, OGLES 3.2, 3.0 works fine, but i haven’t tried OGLES 2.0 with GLSL version 1, what kind of emulator are you testing on ? , Avoid genymotion & non standard emulators because at most times, they got weird gpu setup…
seems there’s a restriction to access gpu of this emulator
Android 2.2 ? you are running on GingerBread don’t you ?
From this message, i can tell that the app is rendered successfully, but what happens after that causes this exception may be due to the driver shaders cannot update the frame buffer…
I think it’s better to search for a device that runs on OGLES3.0 or later as an initial setup…also it supports shaders better on the long run including PBR
If you are at the official android avd, go to the emulator driver settings & try to change the OGLES version to 3.0, after changing the android version to above 4.3
Please report if you still having problems…
NB:
* OpenGL ES 3.0 - This API specification is supported by Android 4.3 (API level 18) and higher.
which states that almost all physical devices supports OGLES3.0
