Steps to Reproduce

When using a map tiler (flutter map) with many tile layers, a limit is reached regarding "Broadcast Receivers" for Android when using NativeAdapter().

"Too many receivers, total of 1000, registered"

So I guess to reproduce, just request too many files over a network in a short period.

Expected Result

All network requests should be honored when using the NativeAdapter packge.

NOTE: if I do NOT use NativeAdapter, and just http, everything works fine for Android. However, the network requests are not as fast as with cronet, so I would rather have NativeAdapter adjusted to allow for > 1000. Or, if you could provide me with a method to "Unregister" or prevent these receivers, that would be great!

Actual Result

java.lang.IllegalStateException: Too many receivers, total of 1000, registered for pid: 27102, callerPackage: com.asdf.asdf

Hi @brianquinlan. Are you familiar with related restrictions?

[gokturkDev]

Im encountering the same issue here and I am not even downloading that many files (not 1000+ for sure). How exactly should we go about debugging this issue

[AlexV525]

@corepuncher: Could you disable the Android minify to produce a raw stack trace? J.N.M6Dz0nZ5(Native Method) doesn't help identify what is registering the listener.

Also, please help us by providing a minimal runnable example.

[brianquinlan]

I'm not at work now so excuse me for the short reply; I think that this happens when you create a new CronetEngine (or CronetClient) per request. This is something of an anti-pattern since creating a CronetEngine is quite expensive.

@brianquinlan Thanks for the insight. I'll look into related paths when available.

Hello yes, this was happening because I was accidentally running a request for every build. I was using a future builder and I thought that its builder was going to execute only when a state change happens, which is stupid in hindsight. Resolved it by using a proper future initalization following the docs:

https://api.flutter.dev/flutter/widgets/FutureBuilder-class.html

@AlexV525 maybe we can display a short message that points the user to look at any excessive requests. kind of like when you use flex wrong and flutter gives you an error message explaining whats wrong

@gokturkDev We must investigate with a proper example to understand what is going wrong. Would you be able to provide a reproducible example?

From @brianquinlan 's idea, this is not the pattern that the plugin is using. The plugin only creates one engine for each adapter. https://github.com/cfug/dio/blob/main/plugins/native_dio_adapter/lib/src/native_adapter.dart

For anyone who is facing the issue, kindly provide a reproducible example for our further investigation, and we might reopen this.
