NDK errors upon compiling for android

[godreborn]

think it said unknown file extensions in the android.mk and application.mk. I followed the instructions to the letter. I'm thinking it has to do with the ndk version, so I'm installing all of them. will that work?

[godreborn]

here's the error:

nm, I figured out the problem. it was the wrong SDL2 type.

[godreborn]

I spoke too soon. I get SDL2 error upon opening the game. it says missing x file. I used the source code, so I don't understand what's gone wrong.

[godreborn]

here's what it does, someone said you needed android 8 or lower for this game to work, is that true?:

[Leonx254]

The symlinks are broken on your end, you can fix it by going to android/app/jni and deleting the files SDL and src (they shouldn't have any format). Then open cmd on this location and type

mklink /D src ..\..\..
mklink /D SDL ..\..\..\dependencies\android\SDL

I had already done that, but still the same error. android studio warns against a file decryptor error. this is a new pc, and a new build. not sure what the problem is.

[godreborn]

just tried again, same error:

[godreborn]

this may be the problem. I may be using the wrong SDL type. I was using the source code one, because that's what it says. is that correct?:

https://github.com/libsdl-org/SDL/releases

[godreborn]

same problem with sonics 1 and 2. I don't understand what's wrong with sdl2. the symlinks are correct. I was able to build sonic mania just fine with symlinks, but it didn't ask for an sdl2 one. I don't understand what's going on.

[morgansakulady]

which application did you use to compile the Android version??

[godreborn]

I compiled them a while ago. sorry, I had forgotten about this posting. it requires SDL 2.0.16 or it won't work on android. it will compile, but you'll get an error when launching the older sonics.

[godreborn]

btw, I was using linux and android sdk as well as android studio. either is fine with my setup.

Closing due to inactivity and because we've since overhauled the building process
