Compiling Forge for Android in Intellij

[lanshark079]

Hello all! After tinkering with the instructions and trying different methods, I was able to set up and build the Windows/Linux version of Forge using IntelliJ as the dev environment. I attempted to build a debug version of the Android version of Forge so that I could work out a bug that only occurs on my specific tablet (Dell Venue 7040/Android 5.1). I added the run configuration using "Android Application" as the base, with the following tweaks:

- Module > forge-gui-android
- Target Device > USB device (for my tablet)

Here's what IntelliJ reported:

Compile Errors | Open

For reference, here's my versions:

Forge: 1.5.49 (Latest from SDK)
IntelliJ: 15.0.4
IntelliJ Android SDK: Maven Android API 20 Platform
JRE/JDK: 1.8.0_73
Maven: 3.3.9
Windows 10

Any advice for properly setting up my IntelliJ environment would be most appreciated. This error is driving me nuts, and debugging this code might be the only way to make Forge work on my tablet once again. Thanks in advance!

Okay, so after getting a few moments to dig in further, I noticed that this project seems to use Proguard to deal with the Dex limit issues. I enabled Proguard in the project in the Project Structure > forge-gui-android > Android settings. I added the proguard.cfg to the config file paths, and had to add two warning suppression commands to that config:

-dontwarn org.seamless.swing.**
-dontwarn java.lang.management.**

Once this was done, I was able to build the APK, push it to my device, and replicate the error! Granted, I have a much longer road ahead trying to figure out how Forge internals even work to understand why "No element named Battlefield, Command in enum zone" is occurring, but at least now I can do more than look at that error and be sad. Hopefully, this post might be able to help someone else with the same predicament. Can't wait to figure this out!

Sounds like a script error. Trying to cast multiple zones into a single zone. But I don't see any occurrences of that string combination in our scripts. Do you have any custom cards that you are using?

Nothing custom - just the stock Forge application. I was able to figure out why the error occurred, though not exactly why it's happening. In the method "listValueOf" inside of ZoneType enum, it splits up a string of the enums provided (Battlefield,Command) into two separate strings using the comma. For whatever reason (and this makes no sense), sometimes the split doesn't work and when it attempts to take the result through "smartValueOf" method, it passes the string "Battlefield,Command", which of course is not found in the enum. When looking at the source string that is the target of the split, there doesn't seem to be any variance between when the split works and when it does not. I'm puzzled, though I will admit my Java knowledge isn't as strong as I'd like. I wrote this garbage code which fixes the issue, and lets the game continue on:

new listValueOf | Open

public static List<ZoneType> listValueOf(final String values) {
//System.out.println("Zone Contents = " + values);
final List<ZoneType> result = new ArrayList<ZoneType>();
for (final String s : values.split("[, ]+")) {
//System.out.println("[" + s + "]");
if (s == "Battlefield,Command") {
//System.out.println("Caught issue with split - fixing...");
ZoneType ztx = ZoneType.smartValueOf("Battlefield");
if (ztx != null) {
result.add(ztx);
}
ZoneType ztq = ZoneType.smartValueOf("Command");
if(ztq != null) {
result.add(ztq);
}
} else {
ZoneType zt = ZoneType.smartValueOf(s);
if (zt != null) {
result.add(zt);
}
}
}

//System.out.println("Result Output = " + result);

return result;
}

In any case, I wasn't able to find anyone else who reported this issue. I'm using a Dell Venue 7040 (which has a small user base), so I'm naturally suspicious that it is somehow causing problems. Does it make sense? No. But there it is. Odd little issue, but at least the workaround is easy (though not for public distribution). Glad it was easy enough to fix, and I can at least compile updated versions as they come along. Which is good, since half the reason I got this new tablet was for this game.

Thanks for looking it over!

Is there a reason you cannot use Eclipse? That's what I use and it compiles fine for that.

This is the command I run to build the .apk in IntelliJ. It should take care of all the proguard stuff, but it does require a keystore.

Maven Only:

Code: Select all

mvn -U -B clean install -P android-release-build,android-release-sign -Dsign.keystore=<keystore_location> -Dsign.alias=Forge -Dsign.storepass=<keystore_password> -Dsign.keypass=<key_password> -Dbuild.max.memory=-Xmx1024m

IntelliJ Build Config (Maven):
Command Line:

Code: Select all

-U -B clean install -Dsign.keystore=<keystore_location> -Dsign.alias=Forge -Dsign.storepass=<keystore_password> -Dsign.keypass=<key_password> -Dbuild.max.memory=-Xmx1024m

Profiles:

Code: Select all

android-release-build android-release-sign

I'll definitely give those build goals a try, Krazy. The app now compiles and works, and with those goals I can make a more efficient APK. I noticed the version I made just using "Make Project" runs a bit slow, which I'm sure has to do with perhaps additional debug inputs that are added to the APK when built without those parameters. Hopefully, the APK resulting from those goals will be more streamlined.

drdev - I originally started trying to set up Eclipse. Using the "How to Get Started Developing Forge" guide, I attempted to set up and follow those instructions. However, some of the instructions were no longer valid or slightly different due to the passage of time (i.e. m2e-subclipse plugin), so I most likely failed when trying to interpret how to perform some of the installations using the updated tools. I used IntelliJ because it skipped the plugins and I was able to get much farther along the compilation details than I could with Eclipse. I'm sure there's benefits to using Eclipse, but IntelliJ seems pretty straight forward and works for my immediate needs, so I was happy to work with that. Perhaps, if I ever do any further development (beyond some minor personal bug fixes), I'll give Eclipse another shot.

Since I'll be building my own APKs for the immediate future until I can confirm this bug with my tablet and .split is fixed, I'll always be grateful for any build suggestions that can help speed this process or build a better APK. Thanks for everyone's input and suggestions - glad this is such a helpful community.
