Android builds frequently OOM

If you are encountering such error while building the app probably means that you might have some issue on your local environment side. I have never seen such error in this project tbh, because of that it is hard to find some better solution than outlining it in troubleshooting section in the README file.

but after a small research, Android documentation doesn't recommend the solution that you suggested:
However, the ability to request a large heap is intended only for a small set of apps that can justify the need to consume more RAM (such as a large photo editing app). Never request a large heap simply because you've run out of memory and you need a quick fix—you should use it only when you know exactly where all your memory is being allocated and why it must be retained. Yet, even when you're confident your app can justify the large heap, you should avoid requesting it to whatever extent possible. Using the extra memory will increasingly be to the detriment of the overall user experience because garbage collection will take longer and system performance may be slower when task switching or performing other common operations.

Instead of that they recommend to find the root of this issue which might be difficult for react-native users. However, I don't think we should suggest it for stripe terminal users.

From my point of view we have two options:

• we can try to find out if your issue is strictly related with the library, if so we need to fix it somehow (if it concerns RN environment - not Android library), otherwise this means there is something wrong with the example app or your local env.
• Simply wait for user's feedback and then react accordingly

I was seeing this too in my own project (not the example) and setting the jvm args as noted in the RN template to use more RAM worked for me.

@cscott-stripe we have it already https://github.com/stripe/stripe-terminal-react-native/blob/main/example/android/gradle.properties#L13

Spoke with @jdivock-stripe offline: this was only occurring when building via Android Studio. Android Studio memory settings take precedence over those set in gradle.properties and should be set to something like:

Closing for now, we can re-open if it occurs again.
