React Native Splash Screen Issue - after modifying xml files in android folder

I would like to create a splash screen in my React Native app (not Expo) using Android Studio's emulator.
I was trying to add a splash_screen.xml file into android/app/src/main/res/drawable folder. When I put a new .xml file into the android folder the React compiler shows the following error message:
iMac:newtest Dora$ react-native run-android
JS server already running.

To suppress this warning, remove "buildToolsVersion '28.0.2'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

Thank you for taking your time to help me to solve this issue!
Cheers,

Well, finally I have managed to solve this issue. It is for those who will encounter this problem during Android development.
So, what i did exactly:
1. cd into android folder and run this: ./gradlew installDebug
After this command finished without any errors
go back to the root directory and start the app using: react-native run-android
Conclusion, if you add or change any xml files in android folder, you have to do the above procedure.
That's all!

The javapackager is unable to generate a dmg on macOS

I am trying to generate a dmg from a jar using the javapackager.
Here is what I put into terminal:
cd "/Users/name/Documents/JarToApplication"
jdk=$(/usr/libexec/java_home -v 1.8)
$jdk/bin/javapackager -deploy -native dmg -BappVersion=8 -name DMSLauncher -srcdir . -srcfiles DMSLauncher.jar -appclass com.blockhead7360.dms.launcher.DMSLauncher -Bicon=package/macosx/DMSLauncher.icns -outdir deploy -outfile DMSLauncher -v
And it runs until here:

I went to the file that it said it was having a problem with (DMSLauncher-dmg-setup.scpt) and when I ran the script manually this is what it said:
Can anyone assist me in fixing this problem? Thank you.

In case someone still sees the problem, what I did to resolve it was to check /Volumes folder and eject the volume. Here the volume would be 'DMSLauncher'.

React-Native build release apk Failed to execute aapt

App works in debug mode just fine by running react-native run-android
But, when I try to build in relase mode by running cd android && ./gradlew assembleRelease
it gives me this error:
android\app\build\intermediates\res\merged\release\drawable-hdpi\node_modules_reactnavigation_src_views_assets_backicon.png: error: uncompiled PNG file passed as argument. Must be compiled first into .flat file..
error: failed parsing overlays.
Failed to execute aapt
com.android.ide.common.process.ProcessException: Failed to execute aapt
I tried workarounds like putting android.enableAapt2=false and org.gradle.configureondemand=true in android/gradle.properties
They both helped me create signed apk but app was crashing on start,
I tried to debug that crash by adb logcat and error is:
FATAL EXCEPTION: Thread-139
java.lang.RuntimeException: Unable to load script from assets 'index.android.bundle'. Make sure your bundle is packaged correctly or you're running a packager server.
Please help me out, I cant seem to figure out how to solve this.

if anyone wonders, we ended up downgrading gradle to
classpath 'com.android.tools.build:gradle:2.2.3'
and it worked.
