The invention discloses a broadcast agent method and device for Android applications. The method includes the steps that a virtual machine environment is established, cloned applications of one or more designated Android applications in an Android system are put in a virtual machine, and the cloned application of each designated Android application and the corresponding designated Android application can operate in parallel; a resident service of the virtual machine agents the cloned applications of the designated Android applications in the virtual machine to receive broadcast messages, and the broadcast messages are forwarded to broadcast receivers of the cloned applications of the corresponding designated Android applications according to a preset strategy. According to the scheme, when the same application is operated in parallel by a user in the Android system, the defects that the broadcast messages cannot be received due to repeated registration information of the broadcast receivers, and even programs cannot operate are avoided.
