I've created and deployed an android app on to the Google play store. Throughout the entire process of developing the app I never ran into any issues with connecting to my online database. Now that I've launched it on the play store I've started having some friends getting issues with it working. After a few days of banging my head against the wall I figured out that they are all on AT&T network. If they connect to a network that isn't AT&T the app works with no issues. Basically it is just blocking the app from using the internet to connect to my database. Has anyone heard of an issue like this? Or have any solutions to get it working correctly on AT&T?
Try accessing your database/server in a web browser in that AT& T network. It may not be blocking your app, but may be issue in accessing your server via AT&T network, which may be caused because of many reasons like some offensive words etc(just a possibility only)

I am working on a Viro Media project with three other people. Two of us have Android, and two of us have iPhones. When one of the iPhone people ran the testbed server with an ngrok link, it seems that both of the iPhone users were able to connect to the testbed. However, when I (android user) and the other android user try connecting to the same link, we get "Error connecting to package server" and "Could not connect to development server" after reloading it. The two of us (android users) decided to run it locally on our own machines to test it while both our server and our phone is connected to the same wifi, and we are both still receiving this error. I can confirm that we all have ViroReact 2.17.0. Is there some extra setup necessary in Android to get this working? Thanks.
After hours of troubleshooting, we figured out the problem. For anyone in the future running into this error, when you put the ngrok link into the app, you must delete out http:// out of the link for it to work.
We have very strange issue.
We are using godaddy domain and google cloud for hosting.
We have App on Android and iOS everything seems working fine.
But Android app taking 40 second to call API. As server log showing request served in 100ms.
This happens with particular when we are on cellular data. All other websites loading fast.
Issue happen Android app + Idea cellular only.
When we hit same API URL on mobile browser it works normal. But in app it takes 40sec to 4 min to get response.
In ios app we are not facing this issue with idea cellular network.
We are unable to debug this issue.
Thanks in advance..
check if the cellular is consuming any proxy. if so disable it and try again. if the problem persists then use cloud flare or google DNS. I hope it will help you out.
I have a situation. My client says they are facing some issue (not a crash) while using the app. We have tried all our ways that could help fixing it. But nothing works out. The best we can do is to travel to client's location- Connect the device to a PC and the debug the issue while inspecting the entire logs. Can all this be avoided? Any app that the client can install and send us the entire logs of app running.
I'm working on real time tracking app, we use firebase database to read/write locations, it was working fine, but lately It doesn't work on mobile data at all, I've searched here and read multiple threads about this issue but there is not enough information about it.
I've tested it on many device, it's the same behavior, firebase doesn't read/write on mobile data, when switching to wifi everything is ok.
Does anyone has the same problem and found a solution to such case?
Maybe this is not a programming problem. You said it was working fine previously. So - in your device go to Settings - Apps - 'your app' - Data usage. Make sure you have switched Mobile data on and you do not have the data limiter exceeded.
I developed android app using this website.

but i am able to login in emulator but when i am trying in my mobile it is not showing anythings. how to over come that.
I had the same problem. The problem might be due to Certificate signing at the time of connection or proxy settings or maybe IP or maybe something like KNOX agent that might stop connection. I started using jdbc and it worked for me. It is easier than php. This might help you JDBC connection in Android.
