Try to upgrade on react-native-push-notification/android/build.gradle this dependencies

def DEFAULT_COMPILE_SDK_VERSION = 26
def DEFAULT_BUILD_TOOLS_VERSION = "26.1.0"
def DEFAULT_TARGET_SDK_VERSION = 23
def DEFAULT_SUPPORT_LIB_VERSION = "26.1.0"
def DEFAULT_GOOGLE_PLAY_SERVICES_VERSION = "+"
def DEFAULT_FIREBASE_MESSAGING_VERSION = "+"

I've had this problem also, after fixing the deprecated 'compile' issue in the dependency configurations - module's build.gradle, however, I didn't change the SDK versions there, instead I've added API Level 28 on SDK Platforms in Android Studio and ... voilà.

Increase the complieSDK >= 26 (Oreo). Notification channel was introduced in Oreo or SDK 26
