6. I turn off the springboot server, the problem is same

7. I can ping 10.0.2.2 success using adb shell in emulator

adb shell ping

adb shell
generic_x86_64:/ $ ping 10.0.2.2
PING 10.0.2.2 (10.0.2.2) 56(84) bytes of data.
64 bytes from 10.0.2.2: icmp_seq=1 ttl=255 time=4.25 ms
64 bytes from 10.0.2.2: icmp_seq=2 ttl=255 time=0.745 ms

64 bytes from 10.0.2.2: icmp_seq=7 ttl=255 time=0.618 ms

8. When I run my app in real machine. Changing 10.0.2.2 to my PC IP. It can get the response successfully. The request content is same except Host.

run success in real machine

Postman

send same post request, and get response success

Question

It seems that there is no question in Android Client and SpringBoot Server.
The only problem is the connection between emulator and PC localhost.
I don't know why my android studio emulator can't access localhost springboot server?

I am facing the same issue. Did you find any fix ?

No, I use real android phone to test the program instead.

You can try this fix:

OkHttpClient client = new OkHttpClient.Builder()
    .retryOnConnectionFailure(true)
    .build();

it doesn't work

retryOnConnectionFailure is true by default but it won't help with "end of stream" error. It only affects connection errors, not malformed or broken responses errors

if this error occurs on a real device, then you can try this:

val httpInterceptor = HttpLoggingInterceptor()
httpInterceptor.level = HttpLoggingInterceptor.Level.BODY
okBuilder.addInterceptor(httpInterceptor)

In my case I started retrofit in a coroutine inside a scope that changed during the HTTP request, cancelling the coroutine with it.

So, check if you call retrofit inside a scope that possibly changed.
