Android Question Crash in my app

[BW17]

Hi,

Sorry for my very bad english....

I have often crashed reported in my Google developer console, on different devices.

It's always :

libcore.io.ErrnoException

emplacement : libcore.io.Posix.open

java.lang.RuntimeException: java.io.FileNotFoundException: /data/data/fr.aires.ccinfos/cache/2: open failed: ENOENT (No such file or directory)

I am a beginner, and can't find why it works on devices and not on same others.

Thanks in advance for your help.

what is that file you're trying to read?

/data/data/fr.aires.ccinfos/cache/2

maybe you should add a check if the file exist before you read it.

This (above) you need to work out what this file is and where it's being used. Of course it could be being used in a 3rd party library or similar.

A little idea of the code or processing would help to us to be able to help you to work out what is going on.. Otherwise it's a bit like shooting in the dark.

The error happens inside HttpUtils2Service.

For some reason these device fail to create a new file in File.DirInternalCache. This folder should be available on all devices.

You can try to manually create it with File.MakeDir(File.DirInternalCache).
