FMOD::System::init crash in Android

FMOD Engine

Running into a crash with FMOD Studio (low level api) version 10602 on Android.

Here’s the output from LogCat. Project is building against SDK19. I saw a similar post that seemed to indicate fmod.jar not in “Order and Export” so I verified that I do in fact have this set.

This is most likely due to the thread you are calling FMOD on not being attached to the Java VM. This can happen if you are using a native activity application.

I will improve the error reporting and platform documentation to better reflect this for a future version.

The required JNI API is AttachCurrentThread, this will allow FMOD to make calls into Java.

Hi
When I use FMOD_System_Init to initialize the system, the return value is FMOD_ERR_NEEDSHARDWARE. I don’t know why it failed. My code：
FMOD_INITFLAGS initFlags = FMOD_INIT_NORMAL | FMOD_INIT_3D_RIGHTHANDED | FMOD_INIT_VOL0_BECOMES_VIRTUAL;
result = FMOD_System_Init(SoundUtil::FMODSystem, 100, initFlags, 0);
, is some initflag have hardware limitation?

It would be best to start a new thread, and link back to this one if you really need to.

Can you please also provide the FMOD version you are using.
