Fatal signal 11 (SIGSEGV) code=2 on genymotion emulator not using NDK

Question

My application does not use NDK. I am testing it on the GenyMotion Nexus 7 emulator and the problem is quite hard to reproduce and I still haven't figured out a correct way to reproduce it. Sometimes the application works fine for a long time and sometimes it just crashes and automatically restarts after about 30 seconds of using.

EDIT: I am not 100% but it only happens on genymotion emulator, but not regular android emulator (I will continue testing).

The problem started happenning when I added support for a large screen when in landscape mode (started displaying two fragments at once in landscape and only 1 in portrait (with width smaller than 720)).

One of the fragments lazy loads images (from memory, disk or internet).

I am quite new to this dynamic adding and removing of fragments so I'm sure there could be something there.

Anyway please help me decode this dump and figure out what's causing the crash (I will try to ommit stuff I think isn't important):

Thanks for your input @Simon, after some testing I started to get an error on the android emulator aswell. But on the android emulator it was a good old OutOfMemory exception. So it turns out that my drawable manager (on one of the fragments) had a huge memory leak where it would bloat a HashMap with drawables. It only became an issue when I implemented the two pane layout, since the DrawableManager would always stay in memory (because the category selection fragment that holds the manager never gets recreated) even when I switched categories.

EDIT: Even though I've solved my memory leak, my genymotion emulator still crashes with the same SIGSEGV, So I guess this question is still open.

Answer 1

Tested Solution its work:

mention these permission in manifiest:

 <application        
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/CustomTheme"
        android:allowBackup="true"           
        android:vmSafeMode="true"       
        android:allowClearUserData="true"
        android:hardwareAccelerated="true" >

Answer 2

I was experiencing this problem also, Specifically with a 4.3 image on GenyMotion. I switched to a 4.2.2 image and no longer experienced the crash.

Answer 3

the solution i found by myself it's to change some attribute on your androidmanifest.xml file

Debuggable = True
VM safe mode =True
Allow Backup = True
Allow Clear user date= True
Hardware Accelerated = True 

(i did this and i dont have this problem and my application ran without problem and i m using Genymotion Too ) On Application menu sorry i forgot this
