I have created an app with two tabs , tab1 as sender (content edittext1 and edittext2 using to enter name and description of listview in the other tab)and tab2 as receiver (content listview),my problem is in get the data out of database and put it into listview ‘ Name and description separated ‘
this is the logcat error :

I am pretty new to docker, but I don’t think I should be seeing go errors as an end user, so I am notifying the community of this bug.
I updated Docker, to version: v2.0.0-rc.1, and then started getting: panic: runtime error: index out of range [1] with length 1, followed by some «go» errors when running docker-compose up. After searching on here, I found similar error messages with using 0 replicas docker/compose-cli#1935, but the error is different (1 instead of 0), and I wasn’t using replicas — unless I am missing something.
Ultimately I ended up using 0 replicas as a workaround to get a proper error message, which was that I had background containers running.

My guess is that something similar to docker/compose-cli#1935 can be implemented to prevent these errors as well.

Steps to reproduce the issue:

1. Updated to version: v2.0.0-rc.1
2. Had containers running in the background
3. ran «docker-compose up» with this docker-compose.yml file:
   services:
   api:
   container_name: api
   build:
   context: .
   dockerfile: api/Dockerfile.api
   image: mutcompute-api
   ports:
   — «5000:5000»
   volumes:
   — ./api:/app/
   environment:
   — MAIL_SERVER=email
   — MAIL_PORT=8025
   command: gunicorn -b 0.0.0.0:5000 api:app
   client:
   container_name: client
   build:
   context: .
   dockerfile: client/Dockerfile.client
   image: mutcompute-client
   ports:
   — «3000:3000»
   volumes:
   — ./client:/app/
   email:
   container_name: email
   build:
   context: .
   dockerfile: api/Dockerfile.api

And an exerpt:
How I fixed it:

I switched to a previous version without db service and was prompted to run docker-compose —remove -orphans, which didn’t really do much. After searching through GitHub issues, and seeing most of the issues were related to replicas, I decided what the heck and added a replica section to the api service. While this error had nothing to do with replicas, I was able to get a different error:

WARNING: The «api» service is using the custom container name «api». Docker requires each container to have a unique name. Remove the custom name to scale the service.

for this error, I just commented out all the container_name sections in each service, and got a new error:

Error response from daemon: driver failed programming external connectivity on endpoint <…> Bind for 0.0.0.0:5000 failed: port is already allocated

Boom! this was the real issue. Searched SO for this, and found out I just needed to run docker-compose down

When I switched back to the branch with the db service, all was working!
