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

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 =“ +”

让我知道这是否对您有帮助

Answer 2

在将deprecated 'compile' issue固定为dependency configurations - module's build.gradle之后，我也遇到了这个问题，但是我没有在那里更改SDK versions，而是添加了{{1 }}在API Level 28中的SDK Platforms上，并且...voilà。

Answer 3

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