处理Firebase远程配置崩溃

Question

I have been working with Firebase remote config for a while in my app, but I notice that when an error data is pushed from Firebase console and app crashes, there is no way you can undo the effect on app crash even after you have corrected the sent data from firebase console. Unless you clear the App cache from Phone or reinstall again the app will crash on starting.

Please is there a way to handle this issue as it will be a total devastating if someone mistakenly crashes his app from Firebase console, users might not go back through this technicalities.

Answer 1

Unless you can arrange for your app to complete a Remote Config fetch, followed by apply of those changes, before the crashing code executes, there's really nothing you can do without publishing a new version of your app that can defend against invalid data coming from Remote Config.

You should always be checking for bad data, even if it comes from Remote Config. Because people do make mistakes.

If you are worried about this in the future, maybe you could code up something where you send a Cloud Message to tell your app to force a fetch, then apply the changes immediately, so that next time the app is launched, it can execute without being affected by bad data.

Answer 2

I am assuming you are using getString() method to get the value of color's hash code. Since the key:value pairs in Remote Config are pure strings, we have no way of understanding what is the correct value in your keys. Is #ffffff correct or 12345 is correct.

When fetching non trivial & business critical values, please process them for validation before you use the values in your codebase.

That said, bringing data types to Remote Config is on our roadmap. It will still not prevent you from making the mistake you mentioned above.

Thanks
