"react-native": "0.47.2",
"jcore-react-native": "^1.1.8-beta2",
"jpush-react-native": "^2.0.9",

依照https://github.com/jpush/jpush-react-native/tree/master/example上面配置，依舊推送不成功，最後發現問題出在兩個地方:
1.在專案的AndroidManifest.xml裡面加上下面程式碼,注意下protectionLevel，這裡是許可權保護設定,我在測試時設定為了normal

<!--新增通知許可權，${ApplicationID}替換成你的applicationID!-->
    <premission 
        android:name="${ApplicationID}.permission.JPUSH_MESSAGE"
        android:protectionLevel="signature"/>

2.開啟node_modules/jpush_react-native/android/src/AndroidManifest.xml，將所有的${applicationId}替換成你的包名。

注意:
npm run configureJPush <yourAppKey> <yourModuleName>
