RPI3 Model B Android Things OS JmE

[Pavl_G]

Hi there,
i 'd like to ask a question about RPI3 Specifically Model B,

if anyone have tried a jme Game using RPI3 M(B) with android things OS installed , i would like to know the general performance of graphics & minimal shaders use , & things that are supported & not supported , because it seems that most features wonot be supported**(OpenGL ES2.0)**.

Thanks

I once tried running my project on a Pi 4 B. If I remember it right, the project did compile, but Minie couldn’t find the appropriate binaries for physics. Not sure about a Pi 3, though.
Doesn’t Android use OpenGL ES2.0, though? If that is true, and since both Pis and Androids use ARM architecture, we may be able to get something working.

@Markil3

OpenGL ES2.0,

yes it is , but it’s currently a low android opengl version that is minimally was introduced since Android 2.2(API8) ,i think currently most devices use OpenGL 3.1 , so that why i am asking , i want RPI3 Model B because of Android Things Project

@Markil3

Minie couldn’t find the appropriate binaries for physics.

Have you tried jme3-jbullet or bullet-native ?

@Pavl_G

Have you tried jme3-jbullet or bullet-native ?

No, I didn’t. I was just trying to see if it could run at all on RPi, and I didn’t really bother taking it too seriously at the time. Later on, the Pi broke down, so that would prevent me from testing it out now.

@Markil3 Though , out of curiosity , I have planned to buy RPI 4 B instead of RpI 3 B due to better cpu , gpu & memory , but Have you tried using Java ME (j2ME) or Pi4j to control a GPiO mode using RPi4 before , I want to make sure that java works perfectly there before buying…

I found this thread from before.

[SOLVED] Development on Raspberry Pi 4

Hi everyone. I recently bought a RP4 and setup java and intelliJ on it and tried to run my existing game code which is very basic and was getting runtime issues because it could not find the native .so file. After digging around I found that LWJGL recently released version 3.2.3 which has finally added support for arm natives. So I edited my gradle file to depend on the new 3.2.3 version and to my surprise it was able to find the library. My happiness was short lived though because it soon fai…

Thanks @pspeed for the guide , seems it’s now fully supported from lwjgl-3.2.3 (ArmV8 x64)

I will try it on the RPI4 B & do an example code on this thread if it works with me .

EDIt: but I actually still having a question ,

Could I use this :
implementation 'org.lwjgl:lwjgl-opengl:3.2.3'(but this wonot include other open source java libraries !?)

OR

This :
implementation "org.jmonkeyengine:jme3-lwjgl3:3.3.2-stable"

Or both if them

I haven’t used j2ME or Pi4j (I don’t think I’ve even heard of the latter). However, I didn’t find it too difficult to get regular desktop Java working on there (I mean, one of the main reasons to get a Pi is for programming. Support for Java is kindof a must). The only issue is getting binaries for ARM architecture.
