Error while running react-native app please help me

WARNING: Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.
It will be removed soon. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html
WARNING: The specified Android SDK Build Tools version (23.0.1) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.5.2.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '23.0.1'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

Check your build.gradle files in your android folder and search for compile and replace it it with implementation.
Change:
dependencies {
compile fileTree(dir: "libs", include: ["*.jar"])
compile "com.android.support:appcompat-v7:23.0.1"
compile "com.facebook.react:react-native:+" // From node_modules
compile project(':react-native-sqlite-storage')
}
To:
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation "com.android.support:appcompat-v7:23.0.1"
implementation "com.facebook.react:react-native:+" // From node_modules

Can't use ConstraintLayout! Error: AAPT2 error: check logs for details

I want to use ConstraintLayout recently. But it seems to be more complicated than I can imagine. When I add the dependency, compile error comes as below:
Error: java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: AAPT2 error: check logs for details
When I execute gradlew assemble, I get this:

and i tried to solve it by adding
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "26.1.0"
}
}
}
}
but it doesn't work
Finished with error: Gradle task assembleDebug failed with exit code 1

Android dependency 'com.android.support:support-v4' has different
version for the compile (26.1.0) and runtime (27.1.1) classpath. So you have to update to be in the same version.
