As it uses plugin version 2.2.0
I have not tested to see if it is compatible with gradle-5.4.1-bin.zip that you have submitted in your PR. I was suggesting gradle 5.4.1 for android plugin 3.5.0 that I am using in the modified build.gradle.
btw, you can find required Gradle version for each plugin version here:
Thanks @sgold, I got it working on the sdk. Now to compile to android and see how it goes.

Ok this is the output I get when running on the emulator.
It fails to start create the physics space.

@Ali_RS: Thank you for that information. As I suspected, building an Android app with JMonkeyEngine is not “easy to do”. That’s why I asked for help, someone experienced to run some tests for me.

That’s an interesting failure. I’ll investigate at my end.
- What ABI were you emulating?
- Did the “Libbulletjme v5.5.3 initializing” message appear anywhere in the standard output? Or did “Bullet-Native: Initializing java classes” appear there instead?
- If neither of those message appeared, try loading the native library explicitly, by invoking
System.loadLibrary("bulletjme");prior to creating thePhysicsSpace.
- I am emulating Galaxy Nexus API 29 (In jME JmeSystem.getPlatform() returns Android_Other).
- It did not print the text “Libbulletjme v5.5.3 initializing” in android but it did print when running on PC.
- It can’t load the bulletjme library I am getting the error below:

Okay I figured out the emulators ABI.
It is x86.
2 Likes
Hm. According to WIkipedia, the Galaxy Nexus had an ARM Cortex-A9 CPU, so I’d expect the ABI to be armeabi-v7a.
In any case, the value returned by JmeSystem.getPlatform() shouldn’t matter, since System.loadLibrary() is supposed to pick the correct native library image based on the platform’s ABI. (jme3-android loads native libraries quite differently from jme3-desktop.)
I read at stackoverflow.com that the 32-bit ARM library needs to be under both armeabi and armeabi-v7a. Currently it’s only under armeabi-v7a, which might be the issue here.
To determine whether the issue you’re seeing is ABI-specific, please re-test on a different emulated device, one with a 64-bit ABI.
Never mind, I think I found the bug. The Android native libraries need to be under lib:
$ unzip -l *.jar

i think this one is more about linux(android in this case) missing libc lib(since you compile, not just use), or maybe it try get it from wrong location somehow.
Thank you @ndebruyn for that information.
There was a warning while building the native library that’s probably related:
Build bulletjme_armeabi-v7a
Android NDK: WARNING:/home/travis/build/stephengold/Libbulletjme/Android.mk:bulletjme: non-system libraries in linker flags: -lc++
Android NDK: This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIES
Android NDK: or LOCAL_SHARED_LIBRARIES instead to list the library dependencies of the
Android NDK: current module
I don’t see how to avoid this. If libc++ isn’t a system library, then what is it?
LOCAL_SHARED_LIBRARIES seems intended for user-built libraries.
I expected the clang linker to add libc++ automatically, but no—if I omit the -lc++ then there are undefined symbols in the link:

clang++: error: linker command failed with exit code 1 (use -v to see invocation)
I’ll research this some more.
Edit: I found this: https://developer.android.com/ndk/guides/cpp-support
Edit: Okay, I think I got this one. Even though I’m not building an application, I still need to supply an Application.mk file. That’s where I specify the libc++ I want. Which is called an STL. Which stands for Standard Template Library.
@ndebruyn We’re making progress. I’m very excited!

Hm. The “C++ Library Support” page says:
If you use
libc++_shared.so, it must be included in your APK. If you’re building your application with Gradle this is handled automatically.
Even if that last statement is true (which I doubt) it leaves me wondering how to support ANT builds. I could add libc++_shared.so for each of the 4 ABIs to the Minie JAR, but that might break Gradle builds. Or I could specify the static version of libc++ during the native build, but that might break applications that include multiple shared libraries (which is just about every JME application).
So when I build my android code I am using gradle to build and not ant.
This is just as a side note.
I’m confused:
I am not using gradle as build system, I am using ant and the sdk.
Should I just manually download Heart?

Please clarify.
