In order to solve the technical problems, the invention adopts the following technical scheme:
one aspect of the embodiment of the invention provides a method for modifying a boot startup program based on an Android system, which comprises the following steps:
saving the package name or null value of the client app in the default startup program package name in a database of the system, wherein the null value is set for recovering the native desktop of the Android as a startup program;
checking whether the stored package name is a null value, if so, failing to modify the starting program, and taking the native desktop as the starting program;
under the condition that the stored packet name is not empty, all launcher programs of the system are checked, if the launcher programs can be found in the launcher programs, the launcher programs are set as default launchers, the launcher programs are used as boot startup programs, and the boot startup programs are modified successfully; if the Android native desktop cannot be found in the launcher program, the Android native desktop is searched in the installed program according to the package name, and if the Android native desktop cannot be found, the Android native desktop is started.
Preferably, for the launcher program, after starting up as the boot startup program, the home key is pressed to return to the program.
Preferably, for the non-launcher program, after the program is started as a boot startup program, the home key is pressed to return to the Android native desktop.
Another aspect of the embodiments of the present invention provides a device for modifying a boot startup program based on an Android system, including:
the storage unit is used for storing the package name or the null value of the client app into the default starting program package name in the database of the system;
the checking and judging unit is used for checking whether the stored packet name is a null value, if so, the modification of the starting program fails, and the native desktop is used as the starting program;
under the condition that the stored packet name is not empty, all launcher programs of the system are checked, if the launcher programs can be found in the launcher programs, the launcher programs are set as default launchers, the launcher programs are used as boot startup programs, and the boot startup programs are modified successfully; if the Android native desktop cannot be found in the launcher program, the Android native desktop is searched in the installed program according to the package name, and if the Android native desktop cannot be found, the Android native desktop is started.
Preferably, for the launcher program, after starting up as the boot startup program, the home key is pressed to return to the program.
Preferably, for the non-launcher program, after the program is started as a boot startup program, the home key is pressed to return to the Android native desktop.
The invention has the following beneficial effects:
(1) the Android native boot startup program can be modified, and the designated program is set as the boot startup program.
(2) The Android native boot startup program may be resumed.
Drawings
Fig. 1 is a schematic structural diagram of a device for modifying a boot startup program based on an Android system according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Method embodiment
A method for modifying a boot startup program based on an Android system is characterized by comprising the following steps:
the package name or null value of the customer's app is saved in the default startup package name in the database of the system. Specifically, the package name or null value of the client app is stored in the default startup package name in the database of the system through the putString method of the Global class in the Settings classes in the Android system.
And checking whether the stored package name is a null value, if so, failing to modify the boot program, and taking the native desktop as the boot program. And acquiring the package name of the default starting program by a getString method of a Global class in the setings classes in the Android system, and comparing the package name with null to check whether the stored package name is null or not.
Under the condition that the stored packet name is not empty, all launcher programs of the system are checked, if the launcher programs can be found in the launcher programs, the launcher programs are set as default launchers, the launcher programs are used as boot startup programs, and the boot startup programs are modified successfully; if the Android native desktop cannot be found in the launcher program, the Android native desktop is searched in the installed program according to the package name, and if the Android native desktop cannot be found, the Android native desktop is started. Specifically, the ComponentName types of all installed launcher programs are obtained through a getHomeActivities method, the package names are obtained through a getPackageName method of the ComponentName types, and then all installed launcher programs of the checking system are compared through the package name string. Find by the getLaunchIntentForPackage method among the already installed programs according to the package name.
Device embodiment
Corresponding to the embodiment of the method, referring to fig. 1, the embodiment of the invention discloses a device for modifying a boot startup program based on an Android system, which includes: the storage unit is used for storing the package name or the null value of the client app into the default starting program package name in the database of the system; the checking and judging unit is used for checking whether the stored packet name is a null value, if so, the modification of the starting program fails, and the native desktop is used as the starting program; under the condition that the stored packet name is not empty, all launcher programs of the system are checked, if the launcher programs can be found in the launcher programs, the launcher programs are set as default launchers, the launcher programs are used as boot startup programs, and the boot startup programs are modified successfully; if the Android native desktop cannot be found in the launcher program, the Android native desktop is searched in the installed program according to the package name, and if the Android native desktop cannot be found, the Android native desktop is started.
Specifically, in the saving unit, the package name or the null value of the app of the client is saved in the default startup package name in the database of the system by the putString method of the Global class in the Settings classes in the Android system.
Specifically, in the detection and judgment unit, the package name of the default startup program is obtained by a getString method of a Global class in setings classes in an Android system, and whether the stored package name is null or not is checked by comparing the package name with null. The method comprises the steps of obtaining the ComponentName types of all installed launcher programs through a getHomeActivities method, obtaining package names through a getPackageName method of the ComponentName types, and then comparing all installed launcher programs of the checking system through package name strings. Find by the getLaunchIntentForPackage method among the already installed programs according to the package name.
In a specific application example, after a launcher program is started as a boot startup program, a home key is pressed to return to the launcher program. And for the non-launcher program, after the non-launcher program is started as a starting program, the non-launcher program returns to the Android native desktop by pressing a home key.
It is to be understood that the exemplary embodiments described herein are illustrative and not restrictive.
