After hours of code review thinking that this is happening when executing something like this but not sure : 

Runtime runtime = Runtime.getRuntime();
Process ipProcess2 = runtime.exec("ping -c 1 -W 2 eakteam.com");

I have tried to read with ndk-stack and others but nothing yet ... If you have noticed that before please help me how to give a solution for this crash.

    EPIPE can happen when you try to execute command which needs root permissions (getRuntime().exec). Don't forget to add permission Internet: "Depending on the environment, the emulator may not be able to support protocols (such as ICMP, used for "ping"). – Jon Goodwin Jul 20 '17 at 12:21
  • Hello thanks for your comment , but i have noticed this only on some devices not at all... And yes i have added the permisions. Anyway, is there any solution for this ? – EAK TEAM Jul 21 '17 at 13:23
  • the difference between play sore emulator and regular emulators are that the play store one has no root access. Maybe same result happen with devices? (rooted vs. unrooted?) – Amir Uval Jul 25 '17 at 21:40

Update:

I was able to run "ping -c 3 127.0.0.1" without problem on the new "Google Play Edition" emulator. So it's not an issue with the elevated privileges. I've searched on Google Play for some Ping apps, and found that there are just devices that just do not support ICMP ping. See this review for example.

ping support is not a core requirement for an Android device manufacturer, and not part of Android library. So some will support it, some won't, some may require root privileges, some won't.

So my best advice is still use a higher level TCP/IP protocol, if all you need it to check your own server. If ping is a requirement, you should install Crashlytics or similar reporting tool, and gradually exclude them in Google Play, to minimize poor reviews.

You've mentioned the crash is in the new play store enabled emulator. So my guess is that the difference is the missing "elevated privileges".

Executing ping would require root permission, so it makes sense that it will fail horribly if you don't have it. It may be a possible explanation for real devices as well.

See the official announcement.

A possible work around this problem would be to do a TCP/IP call to your server from your java code. Here's an example.

  • Thanks for your detailed answer. But how is possibile that this happen on 3/14 devices. The others that are not making crash are unrooted too – EAK TEAM Jul 26 '17 at 01:59
