Topic: BASS for Android

[N/A]

Hi Ian,

i have some problems compiling my app for Android x86. On armeabi it works fine. On every try to compile i get ONE of the following errors:

Do you (or someone else) may have an idea how to fix that?

Thanx

[Ian @ un4seen]

That's strange. I haven't seen those error messages before, so I'm not really sure what could be causing them. It looks like you are building a native app? Please show what the build script looks like. Also, if you remove the "libs/x86" directory, which of those error messages do you get in the next build attempt?

[DevNemo]

is it possible to load an sfpack compressed soundfile? i used the SFPACK.EXE tool, but on my android system i get the err-nr 41 if i try to load a such sfpack file.

the plugins
      BASS.BASS_PluginLoad(libpath+"/libbassflac.so", 0);
      BASS.BASS_PluginLoad(libpath+"/libbasswv.so", 0);

where loaded without any problems.

any idea?

[Ian @ un4seen]

If you open your project's APK file (in its "bin" folder), do you see the libbassflac/wv.so files in it alongside libbass.so? If not, check that they are in the project's "libs" folder and then "Refresh" that folder (right-click on it) in Eclipse. If the libraries are present in the APK and it's still not working, to confirm that the SF2PACK file is valid, are you able to use it on other platforms, eg. with the pre-compiled MIDITEST.EXE example on Windows?

[DevNemo]

no, it dont work. so i also tried the sf2pack.exe which comes along with the windows version, but it's nearly the same. the only difference is when i'm using the sfpack file i dont show up in the miditest tool. if i use the sf2pack created file, it is shown in the miditest tool, but no sounds "0/0" 

[Ian @ un4seen]

Just to be sure, when running the MIDITEST.EXE example, did you put the BASSWV.DLL file in the same directory?

If you like, you can upload your SF2PACK file here, and I'll check it out...

   ftp.un4seen.com/incoming/

[DevNemo]

i downloaded the addOn's (flac, wv, enc) and placed them all in the folder for the sf2pack and miditest and tryed to load the compressed soundfonts. the same result "0/0". so i generated the compressed soundfonts again. now it works.

[Ian @ un4seen]

That looks like it should be fine. What path do you have the BASS SO files in? It should be "jni/x86".

[N/A]

Yep, it's jni/x86.

[Ian @ un4seen]

That's puzzling then. I tried something similar just now, and I didn't get any error messages. That was using the Android NDK on Linux though, while it appears that you're using it on Windows, but I don't think that should make a difference.

Do the "armeabi" and "armeabi-v7a" versions build fine? If so, are you sure all of the x86 SO files are present in the "jni/x86" directory? If that's not it, what happens if you remove all of the BASS library entries from your build script except for the LIBBASS.SO one?

[N/A]

Armeabi worked fine, but it stopped a few days ago with the same errors as x86. I don't know if armeabi-v7a works, but it compiles without any errors. Today i have reinstalled linux (elementary os) on my machine and the the compiler runs fine for all platforms without any errors. But i still can't run my app on my x86 device.

If i remove all bass entries except libbass.so it still throws the UnsatisfiedLinkError.

[N/A]

Aaaaaaaaaaah, solved the problem. Had to include bass, bassenc and bass_fx before mylib:

Code: [Select]

[b]System.loadLibrary("bass");
System.loadLibrary("bassenc");
System.loadLibrary("bass_fx");[/b]
System.loadLibrary("mylib");
Don't know why i didn't need this for the armeabi platform.

[DevNemo]

how to use soundfonts within an apk? should i export them to the sdcard? i saw i could  do also a BASS_MIDI_FontInit using a bytebuffer. could this be done with an "file" located in the apk asset? would it be a good idea to read a asset file into an byte array, convert it to a bytebuffer and using the BASS_MIDI_FontInit?

Yeah, I don't think Android includes the app's "lib" folder in its library search path, so each library's dependencies should be loaded before it is, ie. BASS before BASSenc/FX, and all 3 before your library. It's a bit strange that you didn't have the same issue with the armeabi architecture; perhaps it depends on the Android config, and your armeabi device did include the app's "lib" folder in the library search path?

Yep, you could read the asset into a ByteBuffer and then pass that to BASS_MIDI_FontInit. It might look something like this...

Code: [Select]

try {
InputStream is=getAssets().open("soundfont.sf2");
byte[] buffer=new byte[is.available()];
is.read(buffer);
is.close();
font=BASSMIDI.BASS_MIDI_FontInit(ByteBuffer.wrap(buffer), BASSMIDI.BASS_MIDI_FONT_MEM);
} catch (IOException e) {
// asset fail
}

thank you for all your help!

Ian,

I had posted a prior problem with Android (below), where I was getting lots of skipping on Samsung S3 devices because the audio buffer would empty.  You suggested that I try setting the BASS_CONFIG_DEV_BUFFER to a larger value.

Well I've been playing around with this for a while now, and I've noticed that using larger values makes the problem significantly worse!  If I do a BASS.BASS_SetConfig(BASS.BASS_CONFIG_DEV_BUFFER,90), the audio buffer empties quite frequently. With a buffer size of 20, it is significantly better (actually, it almost never goes empty).

Any idea why this might be the case?  It seems counter-intuitive to me.

Chuck

Thought I'd post a weird Android issue here.  I noticed that on various Samsung devices, my device/audio pauses and stutters quite a bit.  This doesn't happen on my HTC devices.  All devices are Android 4.x (various versions).  I noticed in the LogCat output I'm getting tons of the following messages on the Samsung devices only.  This sequence repeats over and over, and I really have no idea why it's happening, but it's definitely affecting performance.  Any ideas?  I'm not starting/stopping streams or anything like that, just getting data and sending to a single push stream over and over again.

That's strange. I will send you a debug version to get some info on the device buffer updates.

That looks like the BASS library (libbass.so) wasn't included in the app. Does your Eclipse project include a "libs" folder, and does that folder contain the BASS libraries? If not, you should copy the "libs" folder from the BASS package into the project's folder (you may need to "Refresh" the project afterwards).

Yes,my Eclipse project include a "libs" folder.if not,the crash is
     java.lang.UnsatisfiedLinkError: Couldn't load bass from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.example.fxtest-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.fxtest-2, /vendor/lib, /system/lib]]]: findLibrary returned null.
But,my crash is java.lang.UnsatisfiedLinkError: Native method not found: com.example.fxtest.BASS.BASS_Init:(III)Z.
It seem that method not found instand of library not found.  What happen?

have you copied the BASS.java into the "com.example.fxtest" package? it has to be in the "com.un4seen.bass" package to work. the fully qualified name must be correct to find the corresponding native method. so move your BASS.java into the correct package and test again.
