How do I build android application without JME SDK?

Troubleshooting android
1

I have a codebase made in Intellij idea with that plugin. It has different file structure than jme sdk project and jme ide doesn’t understand gradle and its dependencies. Can I build it on android using gradle? May be someone already have a ready-to-use gradle config or some external builder? Or may be there is a way to easily convert my project into jme sdk’s one?

Just like you‘d do a non-jme android project in your favorite IDE. Then you add the jME libraries.

This should be / is in the wiki, but this is the general idea.

I guess the gradle part is confusing at the beginning, so I’ll show you mine, for whatever help it may be. My gradle dependencies also include the required bullet physics stuff. You might also want to ammend the jmeVersion to a release build.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27

    lintOptions {
        // Fix nifty gui referencing "java.awt" package.
        disable 'InvalidPackage'
        abortOnError false
    }

    defaultConfig {
        applicationId "com.jayfella.motorunner"
        minSdkVersion 19

        versionName "1.0"
        // testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }

    buildTypes {

Would be great if someone create guide for expansion file with gradle example.

What does this mean exactly? What does the given tutorial not explain? I ask because I would like to include any issues. I’m currently pretty deep into Android development, so will provide any documentation I have knowledge of.

Hi, currently I am using android studio and easily hit the 100mb quota for apk in play store (even after obfuscation). There is of course a lot documentation… https://developer.android.com/google/play/expansion-files but still practical guide for jme will be cool.

Yes, it’s easy to reach 100Mb between code and assets. My project apk is also over that size right now but it’s not finished enough to be published

It would be a good idea to get all assets into the expansion file instead of the main apk but as far as I know, at least in jme ide itself, it’s not supported :frowning:
