What do you think of building a RN app which use Bluetooth Classic and play async (from an API) audio while the app on the background state?

Most of the hardware will only have a 1GB of RAM and use Android 6.

To be clear, I am building a Push To Talk app.

Hello. My app works fine on a simulator but crashes when I release it in testflight.
Libraries that I use:
-react-native-config@1.3.3
-@react-native-community/google-signin@3.0.3
Those are relevant and you will understand why.
I followed advice from the internet and changed the scheme to 'release'. And I get this error at this line after adding a breakpoint:
line: [[GIDSignIn sharedInstance] restorePreviousSignIn]; in RNGoogleSignin.m
error: Thread 1: "You must specify |clientID| for |GIDSignIn|"

Extra, I submitted the crash from testflight and I opened it with Xcode. I get the error at the same line but different texting: Last Exception Backtrace (0)

I need to mention that I pass the clientId using react-native-config library.

Can you help me? :)

Regards.

Late edit: I use Xcode12 and react-native v0.63.3

Hi Kyle JohnSon,

I would like to know how the background invite message will be sent in react-native?

I have used react-native-message-composer package. But it only works for iOS. But need the same for android as well.

Did you know any other packages?

I have build a deep learning model of image classifier. I want to build an expo app which could take a photo and geolocation. this image should be predicted through deep learning model. And the result should be displayed on screen. I have no experience in app development and read documentation and watched videos but not able to get my answer.I don't even know whether using expo will help or not.

How do you handle the errors you catched after doing a fetch ? Do you handle every errors for every fetch individualy or do you create a function that will handle them ?

let string = "alert('injection success'); var data = "+this.state.data;
this.webview.current.injectJavaScript(string);

Why is it that the alert runs fine but I cant access the variable data from the html template being rendered by the webview?

I try to call it in the script tag like this

document.addEventListener("DOMContentLoaded", function(event) {
alert(data);
});
