Fatal signal 6 (SIGABRT), code -6 in tid 23316 (AsyncTask #1)

[kienntk]

Firstly, thank you very much for your awesome material
I got Fatal signal 6 error when using library.
I have tried with sample project and FC occured too :(.

Kindly help me with this error. Your Library is great

[DeveloperPaul123]

Can you post your code and a stack trace? What version of android are you using?

[kienntk]

I only use sample code to open dialog file picker in OnClickListener of a button in RecyclerView:

Intent filePickerDialogIntent = new Intent(this, FilePickerActivity.class);
filePickerDialogIntent.putExtra(FilePickerActivity.THEME_TYPE, ThemeType.DIALOG);
filePickerDialogIntent.putExtra(FilePickerActivity.REQUEST, Request.FILE);
startActivityForResult(filePickerDialogIntent, REQUEST_FILE);

The stacktrace is only:

After that, I install sample app and got the same problem. I am using Android 5.1.1 with Sony Xperia Z.

[DeveloperPaul123]

This is very interesting. It seems that the AsyncTask is failing in the doInBackground() function when it is trying to get a list of the files in the current directory which is then used to update the UI. From the research I've done it seems that this may be due to the Android runtime thinking that the UI thread is hung so it tries to kill it. This could be due to the number of files within a folder.

Do you have any other devices that you can replicate this on that also have Android 5.1.1? I haven't been able to replicate this on any of my devices.

It might also be good to test if you can remove some files from the device and see if that makes a difference. In the meantime I'll try to look into it more.

[kienntk]

I have tested on Android 6.0 and do not get this issue :(. Ah, I understand, it seems my device has any incorrect files which make library unable to load.

[DeveloperPaul123]

Interesting. Hmmm...Could you try removing any files that you think may be causing problems and then try again? Unfortunately it seems that this issue is unique to your device running 5.1.1.

[kienntk]

Yeah, I see, this occur because of file in my device. How I check and do not get these incorrect file to display?

[DeveloperPaul123]

I'm not exactly sure. Are there any files on your device with exotic file extensions? Or do you have a lot of very large images?

[DeveloperPaul123]

@kienntk Is this still an issue for you?

[kienntk]

@DeveloperPaul123 : I have fixed my files and it's ok. Have some files look like virus on my device, so your library is unable to work with them. I deleted and everything is awesome. You've made a great material. Thank you so much.

[DeveloperPaul123]

@kienntk Great glad you were able to resolve this although it's unfortunate you had a virus. Thanks!
