Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 27830 (ple.myfragexample) -- only on Android 4.1.2

Question

I am using FragmentActivity in my application with several Fragments. Each of these fragments hold an image and some text with animation. When user swipes on the screen, the fragment changes.

Now I have been working on this since 10 days and have tested the FragmentActivity on different devices with different Android versions. The reason that I am stuck on this from last 10 days is I am getting a crash

Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 27830 (ple.myfragexample)

Now, this error occurs only when I test the FragmentActivity on Android 4.1.2 particularly. It would run fine on Android 2.3.3, 4.0.3, 4.0.4, 4.2 and even 2.2. The error log is as below:

I have searched a lot over the internet and tried many thing about this, however, the working of my Fragments got smoother on devices with any other version of Android, but just on Android 4.1.2. I also tried to use Universal Image Loader, but it still crashes with Fatal signal 11. The error log I get when I am using Universal Image Loader is as below:

Now, I know there are lots of questions with Fatal signal 11 on here too, but I am concerned and confused as I am getting this crash only on Android 4.1.2 and not on any other Android versions.

Answer 1

My issue is solved now. I just got my images re-sized from my Graphics team. Previously I was using 1280x768 resolution images but I got them scaled down to 800x480 and the crash is gone. Thanks for all the suggestions though.

Also, I think Jelly Bean (4.x) has enhanced UI and so, it occupies more memory for handling the UI itself than the lower versions of Android, and that's why it was not able to manage handling(scaling down) the larger images.

Answer 2

Have a look at my question:

Strange crash drawing on canvas on Android 4.0.3. A/libc: Fatal signal 11 (SIGSEGV)

maybe it's the same problem. The issue arises when I try to use a small number for stroke or others Paint properties.

setStrokeWidth(0.007f);

Never solved, I suggest to scale the Canvas and use bigger numbers.

Yes, it really is strange but still I would like to get some more suggestions. I have previously used UIL and it is one of the best library to handle images, and I am not able to understand why would it crash with that too. The quality of the image is also of great concern in my App. Apart from all this, when I test my app, it is running fine on devices even with low memory or low specs having any other Android version than 4.1.2. – Hyperdulia

Can you give the library link? – Courage

I suggesto you to refine your question and specify that you're using a specific library with a link. – Courage

Okay, I will edit my Question with the link, however, I actually do not want to use this library. I just tried to check if there was some problem in my code and if UIL was able to manage this problem. I only want to use Fragments with FragmentActivity, as I need to manage animation for each Fragment and also need to handle MediaPlayer for each Fragment. – Hyperdulia
