Android disables an application

When developing an Android Application, consider how to close the application. At first, the current activity is used to call finish (). However, this method is incorrect. In the past few days, when I read the code at the frameworks layer of Android, I found that the platform provided a method to close the program. The following methods are provided in the activitymanager class:
As follows:
/**
* Have the system perform a force stop of everything associated
* The given application package. All processes that share its uid
* Will be killed, all services it has running stopped, all activities
* Removed, etc. In addition, a {@ link intent # action_package_restarted}
* Broadcast will be sent, so that any of its registered Alarms can * be stopped, notifications removed, etc.
*
* You must hold the permission * {@ link Android. manifest. Permission # restart_packages} To be able
* Call this method.
*
* @ Param packagename the name of the package to be stopped.
*/
Public void restartpackage (string packagename ){
Try {
Activitymanagernative. getdefault (). restartpackage (packagename );
} Catch (RemoteException e ){}}
OK. You only need to obtain the activitymanager instance and call this method to close the application normally. The following is a code snippet for closing a program:
Private void exit2 (){
Activitymanager actmgr = (activitymanager) This. getsystemservice (activity_service );
Actmgr. restartpackage (getpackagename ());}
The above method can be called to completely close the program. Generally, the program cannot be completely closed only by calling finish. However, to call the system service, you must add the permission to the androidmanifest. xml file.
