React native app not running on android studio emulator

Question

I was trying to run my ReactNative application on the Android Studio emulator - pixel . But , it's not working and gives the following error instead .

ERROR Error: Exception in HostObject::get for prop 'NativeUnimoduleProxy': java.lang.SecurityException: Permission Denial: registerScreenCaptureObserver from pid=9773, uid=10182 requires android.permission.DETECT_SCREEN_CAPTURE, js engine: hermes ERROR Invariant Violation: "main" has not been registered. This can happen if:

• Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
• A module failed to load due to an error and AppRegistry.registerComponent wasn't called., js engine: hermes

I was trying to run my app on the android studio emulator . It worked perfectly fine when run in VSCode and viewed in an external mobile device instead of using the android studio emulator .

Answer 1

For me, the solution was to delete the previous emulator i had, using the "VanillaIceCream".

Delete the SDK, and then install a new simulator with api 34 ("UpSideDownCake"). The error went away after this.

Answer 2

For me I was struggling with this for days, and then I just updated the Android API SDK to the latest version through Android Studio, and the problem was solved.

If you see update available instead of installed just uncheck and re-check again and hit apply
