React Native Project won't build on expo or on avd - react-native

Question

I just got a react native project and I am trying to run it. When I run:
react-native run-android
, this is my output.
Starting JS server...

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

I have followed all of the directions on the facebook getting started page, but this error keeps popping up. When I run it, I have my AVD running, which is on Android 9. From there, I tried to accept the licenses.

And I don't know what to do from here. I tried expo and it was another rabbit hole... Someone please help! Thanks!

Answer 1

Android Studio > Preferences > Appearance & Behavior > System Settings > Android SDK
Tick the latest Android versions, click Apply.
It's at this point where Android will ask you to agree to its license(s) and the updated version(s) will be installed.
From Here GitHub

Answer 2

I read an answer (Thank you) but it sadly didn't work. I now think that the licenses aren't the problem anymore. I had realized that the project wanted android 27 and I had android 28 installed, so I tried downgrading to android 27. That didn't work, so I just upgraded (I think) the project to android 28 by changing ext in android/build.gradle to:
ext {
buildToolsVersion = "28.0.0"
minSdkVersion = 16
compileSdkVersion = 28
targetSdkVersion = 26
supportLibVersion = "28.0.0"
}
and add this to android in android/app/build.gradle
packagingOptions {
pickFirst 'lib/x86/libc++_shared.so'
pickFirst 'lib/x86_64/libjsc.so'
pickFirst 'lib/arm64-v8a/libjsc.so'
pickFirst 'lib/arm64-v8a/libc++_shared.so'
pickFirst 'lib/x86_64/libc++_shared.so'
pickFirst 'lib/armeabi-v7a/libc++_shared.so'
}
I also had java 10.0.2 installed and I downgraded to java 8. (not sure if that made a difference)
Anyways I hope this helps people get their old projects up to date!
