Describe the problem.

I have an android app that uses a cloud endpoints python backend. I get an 
EOFException in my android app for some requests. But the same requests, when 
retried don't give the EOFException.This does not happen for all request, but 
only for 5-10% of them.

How would you expect it to be fixed?

I would appreciate if there is a workaround till this issue is fixed.

I had the same issue and I resolved by reorganizing the code, but I don't know 
what exactly fixed it, (and sorry I can't rollback at the moment...):

- added the correct intent-filter for the service
- used only local variables for the client endpoint models (i.e. don't use the 
same model twice)
- removed LocalBroadcastManager at all, that was used for returning the result.

hope it may help

I am getting the same issue with NetHttpTransport on Android 4.1. I switched to 
ApacheHttpTransport and the issue was gone.

I switched to ApacheHttpTransport but I started facing other exceptions like 
javax.net.ssl.SSLException: Write error: ssl,  javax.net.ssl.SSLException: Read 
error: ssl etc. It happens generally when switch from 4G to wifi or wifi to 4G.
