Setting a timer for a long period of time warning

[rickardinho]

Hi, I'm getting the following warnings when using socket.io with my React Native project.

I'm on React Native version 0.44.3
and socket.io-client: 1.5.1

Any ideas of how to solve or is this a bug? It seems to be slowing my whole app down significantly, as well as producing lots of console warnings.

Here is the error in the console:

Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See facebook/react-native#12981 for more info.

add {pingTimeout: 30000}to where you tie socket.io to your http server
example:

var io = socketio(server, {pingTimeout: 30000});
```  or some other amount it defaults to 85000 which is more then RN likes

@KingCosmic not work for me

[KingCosmic]

Is your issue the same as the o e here? @ikgsanalatsary

[juergengunz]

does not work for me either

[matthieupinte]

Same warning... but not working for me either @KingCosmic :/
Thanks for your help ;)

[imdadahad]

Facing the same issue, any news?

[KingCosmic]

did you try configuring socket timeout

[matthieupinte]

@KingCosmic tried with { pingTimeout: 30000 }, { timeout: 30000 } as defined in doc. Do I have to do it server-side or client-side ?

[ikhsanalatsary]

@KingCosmic I tried both in server side & RN. But the yellow warning still show

[KingCosmic]

Why am I the only one be here ;-; @ikhsanalatsary what is your error exactly and @matthieupinte server side should be fine how are you connecting socket.io to your http server?

[ikhsanalatsary]

and in my React native app:

dependency:
"react": "16.0.0-alpha.12",
"react-native": "0.48.4",
"socket.io-client": "2.0.4",

server dependency:
"socket.io": "~2.0.3",

[KingCosmic]

@ikhsanalatsary set the ping timeout server side not client side and it should be fixed

[KingCosmic]

That's what fixed it for me anyways
