1. Someone know the reason？
2. Where to download the symbols file?

Thanks!

If you can reproduce the crash while using the FMOD logging libs, that should provide some useful information.

sorry, we can’t repreduce the crash. do you know the function of "0009d7c7 /data/app/com.xxxxx.xxxx-OKRBsnJLXmPeKd63U6TkIg==/lib/arm/libfmod.so "? may be it can help.

I’ve been looking into your crash call stack, I can see it’s coming from our File I/O routines that deal with opening Android assets packaged into the APK. I can see a potential issue internally however I am unable to reproduce the problem here.

Can you verify that you call `org.fmod.FMOD.init(this)` in your activity `onCreate` for the activity and `org.fmod.FMOD.close()` in the `onDestroy`? As per the documentation [here](https://www.fmod.com/resources/documentation-api?version=2.1&page=platforms-android.html#java).

When you call into our init function we cache the Activity context and use it to access the asset manager from our native code. Our examples follow the pattern of initializing the FMOD Java then creating the native FMOD System, mirrored with shutting down the native FMOD System and closing the FMOD Java. Can you check that your application follows that pattern?

we use Unity Integration to access FMOD.  
we find the code we init FMOD, can’t find close in Unity Integation.  
The code is here.

```
static RuntimeManager Instance
        {
            get
            {
                if (initException != null)
                {
                    throw initException;
                }

                if (instance == null)
                {
                    FMOD.RESULT initResult = FMOD.RESULT.OK; // Initialize can return an error code if it falls back to NO_SOUND, throw it as a non-cached exception

                    var existing = FindObjectsOfType(typeof(RuntimeManager)) as RuntimeManager[];
                    foreach (var iter in existing)
                    {
                        if (existing != null)
                        {
                            // Older versions of the integration may have leaked the runtime manager game object into the scene,
                            // which was then serialized. It won't have valid pointers so don't use it.
                            if (iter.cachedPointers[0] != 0)
                            {
                                instance = iter;
                                instance.studioSystem.handle = ((IntPtr)instance.cachedPointers[0]);
                                instance.coreSystem.handle = ((IntPtr)instance.cachedPointers[1]);
                            }
                            DestroyImmediate(iter);
                        }
                    }

                    var gameObject = new GameObject("FMOD.UnityIntegration.RuntimeManager");
                    instance = gameObject.AddComponent<RuntimeManager>();

                    if (Application.isPlaying) // This class is used in edit mode by the Timeline auditioning system
                    {
                        DontDestroyOnLoad(gameObject);
                    }
                    gameObject.hideFlags = HideFlags.HideAndDontSave;

Thank you for the information.

I have a fix in mind that I will put in 2.00.09, please retest when that becomes available.

We have similar crashes occurring in our Unity game using FMOD 2.00.08 – the offset into libfmod.so with version .08 is different but maybe this can correlate with the previous report using .07

We have not reproduced locally but it occurs with some frequency in the real world, with similar reports collected via Google Play, Unity Cloud, and Bugsnag.

It is sometimes corresponding with ad-viewing, although I am not able to say that with certainty. Many breadcrumb report state that an ad was viewed near the time of the crash. We use Unity Ads and IronSource if that matters. Unfortunately I don’t have any more information at this time.

Can you provide an ETA for 2.00.09? We could probably have that integrated and out in the world to many users very quickly.

Here is an example:

```
SIGABRT Abort program 
    /system/lib64/libc.so:139008 abort
    /system/lib64/libc.so:546596 pthread_once
    /system/lib64/libc.so:544368 0x7546606e70
    /system/lib64/libc.so:544000 pthread_mutex_lock
    /system/lib64/libc++.so:629704 _ZNSt3__15mutex4lockEv
    /system/lib64/libandroid.so:56488 AAssetManager_open

```

Thanks!

Really hoping this is fixed in 2.00.09. We have found a case that repros 100% locally and have managed to capture a log with Logging library. There was no relevant output in logcat but this is possibly a more description stack trace. Captured with FMOD 2.00.08 Unity integration:

I do see this near the crash:

```

I’m glad you have a 100% repro, please test with 2.00.09 (available now).  
If you are still having issues I can work with you to get it resolved.

We have this same crash issue with Fmod 1.10.02 on Android 9 and 10 so really looking for if the 2.00.09 fixes the problem. Please if possible, keep posting your findings to this thread to keep us all with the same problem informed for possible fixes. Thank you all.

Can confirm that the issue have been solved by the update, our project just developed other issue from the update but that´s different story and can be followed in here: [Crash on FMOD Studio Update thread, Fmod Version: 2.00.09](https://qa.fmod.com/t/crash-on-fmod-studio-update-thread-fmod-version-2-00-09/15832/9)
