Answer 1

尝试在react-native-push-notification/android/build.gradle此依赖项上升级

• 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”

H19定义DEFAULT_GOOGLE_PLAY_SERVICES_VERSION =“+”H210H111def DEFAULT_FIREBASE_MESSAGING_VERSION =“+”H212F213

如果这对你有帮助，请告诉我

Answer 2

我也遇到过这个问题，但是在修复了dependency configurations - module's build.gradle中的deprecated 'compile' issue之后，我并没有在那里更改SDK versions，而是在Android Studio中的SDK Platforms上添加了API Level 28……瞧啊。

Answer 3

增加complieSDK >= 26 (奥利奥)。通知通道是在Oreo或SDK 26中引入的
