Issues filed here should be about bugs in the code in this repository.
If you have a general question, need help debugging, or fall into some
other category use one of these other channels:

• For help troubleshooting your application that does not fall under one
  of the above categories, reach out to the personalized
  Firebase support channel.

[REQUIRED] Step 2: Describe your environment

• Android Studio version: _____
• Firebase Component: com.google.firebase:firebase-perf
• Component version: com.google.firebase:firebase-bom:33.1.0 (Reproduced since com.google.firebase:firebase-bom:31.5.0)

[REQUIRED] Step 3: Describe the problem

Calling URL.openConnection() from separate process will lead crash with Firebase Performance.

Steps to reproduce:

1. Add Firebase Perf to project.
2. Make network request with UrlConnection from activity.
3. All works.
4. Than move activity to separate process. Activity just for simple example. It can be a service in a separate process.
5. Crash occurs.
6. Expected behavior: Requests will be executed correctly in a separate process without activating FirebaseApp.

It works correct up to com.google.firebase:firebase-bom:31.0.0.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @alexklints, thank you for for reaching out and raising the issue. Thank you for sharing an MCVE. I was able to reproduce the issue from version 31.2.0 up to the latest version. I'll notify our engineers about and see what we can do here. Thanks!

Firebase only initializes automatically on the default process of an app. If you have a multi-process app, you need to initialize manually in each process or not use Firebase in the other processes.

To initialize manually, you could do something like this:

class MyApp : Application() {
  override fun onCreate() {
    super.onCreate()

    // Initialize Firebase in other processes.
    if (getProcessName() != applicationInfo.processName) {
      FirebaseApp.initializeApp(applicationContext)
    }
  }
}

Hi.

I understand, but the thing is, the behavior used to be different. Firebase Performance did not attempt to intercept the network if there was no initialization in the process. There are such examples of an issue where developers tried to implement this behavior:

• https://github.com/firebase/firebase-android-sdk/pull/5616/files
• Initializing the SDK programmatically by using FirebaseOptions cause crash when call URLConnection.getInputStream() #5584
  In addition, many developers, unfortunately, are very little familiar with the concept of a process. They add a library that adds a process to the application. And everything starts to fall for them.
  In addition, Firebase is not well adapted to multi-process applications. Crashes and ANR occur periodically when trying to initialize Firebase and its individual components in more than one process.
  I believe that if you fix this issue, it will become easier for many developers.

I took a look, and this was fixed in Firebase Perf 21.0.1, can you try the latest version @alexklints?

Please open a new issue if this was not resolved in the latest version for you.
