The invention provides a method for pre-installing a third-party application as a
system application in a cloud
mobile phone, which comprises the following steps of: setting a configuration
list deeleteAppFilm of applications which cannot be uninstalled under / data / local / control / path of a cloud
mobile phone system, and adding a cloud application
package name of the third-party application which needs to be pre-installed as the
system application into the configuration
list deeleteAppFilm; when the cloud application is installed, marking the third-party application appearing in the configuration
list deeleteAppFilm as a system application, and when the cloud application is installed, marking the third-party application appearing in the configuration list deeleteAppFilm as the system application; the method comprises the following steps: when a cloud
machine system is restarted, setting application data of a third-party application appearing in a configuration list deeleteAppFilm to be undeletable; and when the cloud application is unloaded, the third-party application appearing in the configuration list deeleteAppFilm is set to be ununmountable. According to the method, the third-party application is pre-installed into the system application in a dynamic configuration mode, the limitation of the size of a system
mirror image of a cloud
machine system can be broken through, multiple third-party applications can be pre-installed into the system application conveniently, the compatibility and expansibility of the cloud
machine system are improved, and the user-defined requirement of a user is better met.
