help on standalone game

Post by dudeabot » Tue Nov 13, 2012 3:07 am

well i have read a lot of threads.

first, id ilke to say im studying ni and might be able to help, but i would like to ask first. is the problem of standalone apk resolved? if not i might have a look at it, i just compiled the ndk sources, and love looks like such a cool engine that i have been wanting to mess with.

just bare with me since i am veeeryyyyy rusty with jni and NDK =)

thanks!

I don't think anyone has actually managed to get a stand alone apk yet. But it is theoretically possible. Maybe not in this version though.

ok i compiled my version, unfortunately it doesnt run, im using android-ndk-r8b and android sdk 4.0.3(im having exactly this error)

http://stackoverflow.com/questions/1217 ... ad-library

well anyway ill outline my path so anyone who can compile can test if it works or not:

1)find apk path on java:

Code: Select all

	String retrieveApkPath() {
		String apkFilePath = null;
		ApplicationInfo appInfo = null;
		PackageManager packMgmr = getPackageManager();
		try {
			appInfo = packMgmr.getApplicationInfo(getPackageName(), 0);
		} catch (NameNotFoundException e) {
			e.printStackTrace();
			throw new RuntimeException("Unable to locate assets, aborting...");
		}
		apkFilePath = appInfo.sourceDir;
		return (apkFilePath);
	}
2)PHYSFS_AddToSearchPath(apkPath, 1);i think this is done on lua level, especifically on boot.lua right where it boots the game source.. so you should access the filesystem from there and add the apkpath

from there on its just a matter of loading the .love file (hopefullly)

for example, create a folder assets and put your .love file there lets game.love, step 2) should make it visible to physfs so yuo can replace the boot code to load game.love instead of the argument

here is my progress so far

Code: Select all


love.filesystem.addToSearchPath(apkDir); -- apkDir sent via Java code, i also added addToSearchPath to lua-glue code.
print(love.filesystem.exists("/assets/game.love")) -- works :D, if you have copied game.love to assets folder
the problem is that its a zip inside another zip, and even worse, assets is a folder, so finding main.lua has been a hell for LOVE so far :P


------------------------------------------------------

meanwhile i found this hack that doenst require messing with NDK code, only java:

http://stackoverflow.com/questions/4447 ... -to-sdcard

the idea is to copy the .love game to assets folder then use that code to copy to sdcard and pass its location to JNI. the obvious fallback is that requires sdcard, also duplicates the game in memory..

It doesn't require a physical sd card though. Many phones without them still have the folder /mnt/sdcard for compatability. And Environment.getExternalStorageDirectory() should still work either way.

yes, only older phones would have issues..

mine doesnt have any problem (galaxy s2).. but still pretty hacky isnt it?

ok i have tested the "hack" and it works

DOWNLOAD: http://gjteam.com.br/love-native-android.apk

here are the files that I changed (i dont have git client here to make patches, if anyone knows a good client for windows..)

make sure you create a folder called "assets" inside the root of java project and copy your game to there, name it "game.love"

Dude, you're awesome! :D

Sorry, English isn't my native language, but I wanted to ask if I understood correctly.

You got it working, so a stand alone *.apk of your game would be playable on the phone, without "Browse for game" before?

If so, may I ask for a little little tutorial on how to do that? Because I get errors when changing the LoveNative.java.

Also you could test just replacing the .love file file by your game in my APK (in the other post)

of course the apk is signed by me, so it might not be interesting for sellin purposes, just for tests. you should want package yourself with the changes provided ;)
