由启动命令“/usr/bin/uengine --package=org.anbox.appmgr --component=org.anbox.appmgr.AppViewActivity”得知uengine是在Anbox开源项目上二次开发得到的，启动的应用是org.anbox.appmgr，启动入口是AppViewActivity。

很多子命令可以直接用：

$ uengine help
NAME:
    uengine - uengine

USAGE:
    uengine [command options] [arguments...]

COMMANDS:
    wait-ready                     Wait until the Android system has successfully booted                                               
    system-info                    Print various information about the system we're running on                                         
    check-features                 Check that the host system supports all necessary features                                          
    version                        print the version of the daemon                                                                     
    launch                         Launch an Activity by sending an intent                                                             
    install                        Install specified application in the Android container                                              
    session-manager                Run the the uengine session manager                                                                 
    help                           prints a short help message                                                                         
    uninstall                      Uninstall specified package in the Android container

像system-info check-features等和Anbox如出一辙。

因此，启动时的各种错误解决不了可以去Anbox Issues里看看有没有解决方法。
