1         androidShutDown           Shutdown Interface                         Need the system signature (Scheme set out 4.1-2) PicoUnityActivity.CallObjectMethod("androidShutDown")
2         androidReBoot             Reboot the machine                         Needing the system signature (Scheme set out in 4.1-2)  PicoUnityActivity.CallObjectMethod ("androidReBoot")       
3         androidLockScreen         Lock screen                                PicoUnityActivity.CallObjectMethod("androidLockScreen ")
4         androidUnlockScreen       Open screen                                PicoUnityActivity.CallObjectMethod("androidUnlockScreen ")
5         acquireWakeLock           Request WakeLock                           Must appear in pairs with "releaseWakeLock" PicoUnityActivity.CallObjectMethod ("acquireWakeLock ")     
6         releaseWakeLock           Release Wakelock                           Must appear in pairs with "acquireWakeLock”   PicoUnityActivity.CallObjectMethod ( "releaseWakeLock  ")     
7         goToApp                   Go to App                                  PicoUnityActivity.CallObjectMethod ( "goToApp", "package name of the App jumped to");
8         setpropSleep              Set the system sleep timeout               Parameter: "-1" means never sleeping, for example: PicoUnityActivity.CallObjectMethod ("setpropSleep", "-1");                 
9         setPropLockScreen         Set screen off timeout                     Make sure to call "setpropSleep" first, and the time out value should not be larger the one for setpropSleep interface.Parameters: "65535" means “always on display”    PicoUnityActivity.CallObjectMethod("setPropLockScreen ", "65535");           
10        silentInstall             Silent installation                        Need the system signature, need to add parameters: apk storage path and name, and package name of current application.   PicoUnityActivity.CallObjectMethod("silentInstall",new object[] { "/storage/emulated/0/Download/PicoVRtest.apk", "com.example.picovrpowermanager" });
11        silentUninstall           Silent uninstallation                      Need to add parameters: apk's package name  PicoUnityActivity.CallObjectMethod ( "  silentUninstall  ")
