This is probably the wrong place to ask this question, but I've been noticing that pelya's ports of Ur-Quan Masters and Tyrian work reasonably well... as long as the music is off, at which point the framerate drops through the floor. Does anyone have any insights as to why this might be happening, or similar experiences? If I play with the code, are there likely to be any easy ways to improve things?

(Note: it may just be my cruddy Huawei U8300 phone, ARMv6 and no GPU, and seems to burn CPU with non 44.1khz audio based on video playing experience)

Your last commit was done 2 months ago, as my Git history shows, so you did not screw anything.

I'll check the start-up menu timeout set to zero, maybe there's a bug, because I rarely use such setting.

According to the specs, it has 528 MHz CPU and 256 Mb RAM, which is indeed low-profile. UQM uses .OGG music, which is like 2x-3x more CPU intensive compared to playing .MP3 file, and it is using fixed-point decoder which also gives some strain on CPU (I cannot give hard numbers here, just approximation).
OpenTyrian though should not be so slow, because it's music plays through emulated OPL3 chip or something like that.
Anyway, you may try to increase audio buffer size in SDL startup settings, it should give some minor performance improvement (and some audio lag too).

Thanks for the insight (and prompt response). Yes, sounds like the OGGs would mess things up (should have discovered that myself). But isn't the only alternative to the fixed point decoder a floating point one (i.e. probably even worse for ARM)? Also, I assume neither tries to use Android's default audio handling (therefore using a DSP for MP3s at least)...

With OpenTyrian, I guess the OPL3 emu is just the straw the breaks the camel's back on top of the sound effects and the framebuffer. But it's annoying that it apparently works ok on a significantly lower-spec device (GP2X) with only a drop to 22khz audio, whilst Android apparently adds enough overhead for it to fall over completely.

The audio path in Android is indeed complicated - when SDL generates a new chunk of audio data it feeds that to the Java code (it uses android.media.AudioTrack API), the Java code feeds it to the AudioFlinger system service (which is basically a separate process that manages audio), and AudioFlinger mixes the audio from multiple sources and feeds it to the underlying Alsa drivers. Also almost all apps use 44kHz audio, that depends on the app itself however.

Most middle and high-end phones have hardware floating point support, and it impacts the .OGG decoding speed a lot, however I still cannot give any hard numbers here because I did not do any measurements. On the other hand, high-end phones can decode .OGG with reasonable speed even using fixed-point decoder, and low-end phones do not contain hardware FPU, so I'm usually releasing apps for only fixed-point ARM architecture.

BTW your phone has enough buttons, you may try to disable on-screen controls from SDL startup menu, this should increase FPS for a bit.

Hello,

Just wondering about internationalization .. not to handle the many encoding available, but how to provide a text in the native language of the user ?

How would you do that? Is it a phone/android property ? would a "getenv(LOCAL)" be fine ?

thanks,

SDL sets environment variables LANGUAGE and LANG to the code of the current Android OS language, before runnong your main(). So getenv("LANG") in the C code will return you something like "en" or "en_US".

Ok ! Thanks for the fast answer !

It adds the country code too, so you might want to strip it out in your Settings.java file:

Code: Select all

String lang = new String(Locale.getDefault().getLanguage());

      // GJT: Only get country code of PT or ZH
      if (lang.startsWith("zh") || lang.startsWith("pt"))
      {
         if( Locale.getDefault().getCountry().length() > 0 )
            lang = lang + "_" + Locale.getDefault().getCountry();
      }

      System.out.println( "libSDL: setting envvar LANGUAGE to '" + lang + "'");


Ok thanks for the snapshot ! I do it from native layer, so I get whatever is in getenv("LANG") and only consider the first two chars.


Here's another question : how to add an external Jar into the pelya-build process (without using Eclipse!) ??

And also :
What about putting some extra "user" variables into the AndroidAppSettings.cfg ? So that the user can customize a little bit the *.java templates.
(basically user_field_[1-10] that would appear as Java String in the MainActivity template or as global variable(?)) ?

Hi Pelya,

Could you please check that the main() function in your sources actually called SDL_main() ? It happens automatically if you do "#include <SDL.h>" in the file where you're defining main() (it's done like "#define main SDL_main"), you can always do that by hand though.

I've included ""#include <SDL.h>"", I also tried direclty to change "main" to "SDL_main". But the result is the same. Though we found if make some change, e.g. add or remove some __android_log_print(), sometimes it could build successfully and run correctly on emulator. Is this SDL.h able to include in other .c file without main function? I ever included it in another .c file, I remove it just now and compile again, the new generated apk can run on emulator. But there is new error like the log below. PS: I build using android-ndk-r7.

Code: Select all

That seems to be some error in your code, stack trace is too short to say where. The most common errors are unaligned pointer or access, such code will run okay on PC but will crash on Android.

I cloned the repository, and tried to compile ufoai and glxgears, and both run into the error that GLES/gl.h cannot be found. I'm using crystax NDK 6.2 on Arch Linux. I notice that the output commands say -I/opt/android-ndk-crystax/platforms/android-3/arch-arm/usr/include , but there's only GLES in android-4 or above in my crystax installation. I can't figure out where this 3 is coming from...project/project.properties says target=android-12 (and crystax platform directory has only android-3,4,5,8,9). Some files in the git clone contain PLATFORMVER=android-8. But I guess neither of these numbers is getting used?
