React native app not running on android studio emulator

enter image description here

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 .

    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

    For me, the solution was to delete the previous emulator i had, using the "VanillaIceCream", delete the SDK, and them install a new simulator with api 34 ("UpSideDownCake").
    The error went away after this.
