Build Failing on Android. Cannot find symbol JobIntentService about react-native-boundary

Need to change all the imports from android support library to androidx library. Was facing the same issue, but changing all the android support library imports to androidx library solved the problem.
But first, you need to mention all the required libraries in your dependencies block in app/build.gradle file like this-
implementation('androidx.appcompat:appcompat:1.4.0') implementation('androidx.legacy:legacy-support-v4:1.0.0') implementation('androidx.annotation:annotation:1.4.0')

It seems like you need to force the versions within your android/build.gradle file. You can do that by adding

ext {
  compileSdkVersion = 27
  buildToolsVersion = "27.0.3"
  targetSdkVersion = 26
  minSdkVersion = 16
  supportLibVersion = "27.1.1"
  googlePlayServicesVersion = "11+"
}

To the file, then reference it within your android/app/build.gradle like so,

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
    ...
    defaultConfig {
        ...
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        ...
    }
dependencies {
    ...
    compile "com.android.support:appcompat-v7:$rootProject.supportLibVersion"
    ...
}

If that doesn't work, then try to search around for how to force versions in Android. Hope this helps!
