The Unofficial Epic Android Compiling Guide

[VirtuGuy]

Have you ever wanted to compile your build of Friday Night Funkin' to an Android device? Possibly to recreate the nude bf build of the game that probably shouldn't be talked about or to fix real problems with FNF on the phone? Well I'll tell you how! Follow the steps below and you should get a working build of FNF.

Just know that this guide is made only for Android and Windows. If you're working with IOS or Apple or whatever, it's probably best to take a look at the official mobile compiling docs.

You also need to make sure that your FNF source code actually works. You can test this by compiling the game to desktop or web.

Instructions

1. Create a folder anywhere on your computer. This is where your Android Tools will be located, so remember where it is.
2. In a command terminal opened as an Administrator, run setx ANDROID_HOME "C:\path\to\your\folder" /M.
3. Download Android Command Line Tools.
4. Extract the downloaded zip and move the folder called cmdline-tools to your Android Tools folder.
5. Move the contents of cmdline-tools into a folder called latest, which is created inside of cmdline-tools.
6. Download and install JDK 17 MSI.
7. Open a command terminal from cmdline-tools\latest\bin and run sdkmanager --install "build-tools;35.0.0" "ndk;29.0.13113456" "platforms;android-29" "platforms;android-35" "platform-tools".
8. In a command terminal, run lime setup android.
   When asked, use these:
   • Android SDK: C:\path\to\your\folder.
   • Android NDK: C:\path\to\your\folder\ndk\ndk-version.
   • Android JDK: C:\Program Files\Java\jdk-version or C:\Program Files\Eclipse Adoptium\jdk-version.
9. Ensure that developer mode and USB debugging are enabled on your Android device.
10. In project.hxp, which is located in the game's source code folder, change PACKAGE_NAME to your own (ex. com.username.fnf). You do not have to follow this step if you don't have Friday Night Funkin' installed on your phone, but I suggest doing so anyway. If you have already successfully compiled the game to Android, but it's giving you the same problem for as if you never changed PACKAGE_NAME, simply uninstall your compiled version of FNF Mobile and compile the game again.
11. From the source code folder, open a command terminal and run lime test android.
    • Your phone must be plugged into your computer or else it'll be unable to transfer the exported game files onto your phone.
    • This step also takes a while, but if your phone supports it, you can add -DEXCLUDE_ARMV7 at the end of the command you are about to run.
    • "Performing streamed install" means that all the exported game files are being transferred onto your phone.
    • After compiling for the first time, compiling won't take as long.

Conclusion

If this guide worked, great! If it didn't, then you should be able to ask somebody for help. I probably can't help because I'm not an expert at Android game compiling stuff.

Great guide! Hopefully it gets more people compiling for Android. Also if your phone supports it, you can speed up compilation time by disabling compilation for ARMv7 with -DEXCLUDE_ARMV7, not sure if there's an alternative for ARMv7-only phones though.

Updated the guide a little while ago to use command-line tools instead of Android Studio itself.
