我将在我的应用程序中使用react-native-push-notification作为通知，但是当我使用这个库时，它会给我这样的错误......

尝试升级react-native-push-notification/android/build.gradle这个依赖项
- 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 = "+"
让我知道这是否对你有帮助
