插件工程 线程问题Can't create handler inside thread that has not called Looper.prepare()

[astro5206771]

异常信息如下: W/System.err(1585): java.lang.RuntimeException: Unable to create Application for com.XX.android.XX: Can't create handler inside thread that has not called Looper.prepare()
貌似是插件项目功能里需要在主线程里调用，而pluginmgr是新启动一个工作线程调用，如果在主线程中调动pluginmrg不会阻塞吗？这个该怎么解决；
