As soon as I am adding FMOD to my Android.mk, my app is crashing.

These are the extra lines I am adding to the android.mk file supplied with android_template:

LOCAL_MODULE := fmodex
LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/libfmodex.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../../../common/include
include $(PREBUILT_SHARED_LIBRARY)

LOCAL_SHARED_LIBRARIES := fmodex


Any idea what I am doing wrong, as I spent 2 days testing & researching without success

I've not tried it with a prebuilt shared library, it's possible the library is not being uploaded to the device. Is there a static alternative?

unfortunately no, they only supply that one shared library

Do you think I should give up and stop wasting my time, or maybe there's a small hope for a solution?

In your Application.mk there should be an APP_MODULES line, try adding fmodex to it (separated by spaces), which should move it to the libs folder, then hopefully eclipse will pick it up and put it in the apk. If not you can add it, should look something like this

APP_MODULES := android_player fmodex

Will check it out. Thanks for the interest and help.

Paul, on a totally different subject, check out this guide...

Do you think this can be implemented and make the recompiling process more transparent for users?

The settings suggest that eclipse must be able to run the ndk-build script without going through cygwin, which normally I would say isn't possible. However I did notice that v7 of the NDK introduced a bat file for compiling on Windows without needing cygwin, I've not tried v7 yet so I don't know if it is any good or if it would work with this method, but it's possible.

And we are using the r7 of the ndk right, as that was the latest one in the download section

Tried this

APP_MODULES := android_player fmodex

But it still crashes.

This is the ndk-build compile output. Seems like the libs are installing.



What does exactly the 2> parameter in ndk-build do?

I'm using 6b, if anything v7 should be better with this sort of issue.

It pipes the stderr output into a file instead of flooding the console window, so that the window just gets stdout.

Everything looks in order. Where did you get the libfmodex.so lib from, is it compiled for armeabi?

I tried this, and it works great!

Every time I edit my template.cpp in Eclipse and save it, it automatically gets recompiled, without having to go in Cygwin! I think it's worth extending the Android guide to include this as an optional commodity!

It seems that Android does not automatically load dynamic libraries at runtime, so one has to do this manually in the correct dependency order, in Java.

The Fmod examples use this Java code, which I think I need to somehow integrate instead of the DUMMY class in agk.



How can I do this successfully?

All FMOD examples have a static section in Java that loads the lib. One must subsclass native activity just so you can hook some static code to load the libs before the native activity is launched.

I have absolutely no experience with Android and this is driving me crazy! I managed to implement fmod playback in Windows and iOS without any problem!!!
