Background
In combination with the ecology of large and small screen mutual projection, the concept of rotating television starts to rise, and different implementation schemes appear. One implementation scheme is to simulate the rotation of a mobile phone, and a gravity sensor is arranged in the television, and a rotating support is arranged outside the television, so that a user can manually control the rotation of the television to realize the switching between a horizontal screen and a vertical screen.
However, this implementation presents certain problems in applications that require either a forced landscape or forced portrait. Specifically, for a mobile phone user, when the mobile phone user faces the application of a forced transverse screen or a forced vertical screen, the mobile phone can be flatly placed on a desktop for use by fully utilizing the Z-axis direction; however, for television users, there is no scenario for use flat on a desktop. This means that, on the television system, the user's look and feel is very poor when the forced portrait software is displayed in the landscape state of the television or when the forced landscape software is displayed in the portrait state.
On the other hand, most of the current third-party television software is only adapted to a horizontal screen but is not yet available or is not intended to be adapted to a vertical screen, and if a user unwittingly rotates the television without corresponding rotation of the picture, the user is also provided with very poor use experience, and even the illusion that the television or the software goes wrong is generated.

In this embodiment, first, the package name of the first application home page and the package name of the second application home page need to be set, and then the two package names are set in the custom system property persistence. Meanwhile, a custom code is added in the choposeBestActivity function of PackageManagerService. The custom code, when executed, performs the following decisions: when the ChooseBestActivity finds the best candidate for the home page, if the value of persistence.XXX.launcher is not null, then the candidate in the candidate list that contains the value of persistence.XXX.launcher is the best candidate.
Therefore, when the change of the placement state is detected, the television can acquire the corresponding package name according to the placement state and read the corresponding application home page according to the package name.
In this embodiment, the applications in the first application home page and the applications in the second application home page may be manually set by the user, that is, the user may place the application with the landscape screen display function into the first application home page and place the application with the portrait screen display function into the second application home page. Of course, when the application is installed by the television, the display mode of the application can be obtained by reading the specified parameters in the application and placing the application into the corresponding application home page, and these schemes are all within the protection scope of the present invention.
It will be appreciated that for some applications having both landscape and portrait displays, it may exist within both application home pages.
S103, setting the corresponding home page application as a default home page application so as to display the home page application when receiving an instruction of returning to the home page.
