极光推送获取不到RegisterId(注册ID)Android

• 摘要：官方文档介绍了两种获取RegistrationID的方法:https://docs.jiguang.cn/jpush/client/Android/android_api/#registrationid-api//SDK初次注册成功后,开发者通过在自定义的Receiver里监听Action-cn.jpush.android.intent.REGISTRATION来获取对应的RegistrationID。注册成功后,也可以通过此函数获取publicstaticStringget

  //SDK 初次注册成功后,开发者通过在自定义的 Receiver 里监听 Action - cn.jpush.android.intent.REGISTRATION 来获取对应的 RegistrationID。注册成功后,也可以通过此函数获取 
  public static String getRegistrationID(Context context)

   

  在下看来第一种是误导,应该在application中才能拿到!!!而不是自定义Receiver!在application中对其进行的初始化!!

  
  registrationId = JPushInterface.getRegistrationID(this); 
  Log.e("1099", "run:--------->registrationId: "+registrationId );
