What happens to the main function when Android can't see it? The program is abnormal, can not prompt "XXX software stop execution"?

Today, I met this problem and shared the solution.

Android does not have a main function, and naturally there is no solution to add exception handling in main to achieve global exception capture. Does the Android program have a global exception replenishment solution?

The answer is:

That is, you have to inherit the androidproject inside the application, such as:

public class Readerapplication extends application implements thread.uncaughtexceptionhandler{...}

and implement the thread exception replenishment interface: Thread.uncaughtexceptionhandler

This way your program, which only has unhandled exceptions, will be captured in the following uncaughtexception function. My practice is to restart the application.

@Overridepublic void uncaughtexception (thread thread, Throwable ex) {//TODO auto-generated method stub//system.exit (0) ; Intent Intent = Getbasecontext (). Getpackagemanager ().              getlaunchintentforpackage (Getbasecontext (). Getpackagename ());                      Pendingintent restartintent = pendingintent.getactivity (                    getapplicationcontext (), 0, intent,                    Intent.flag_ Activity_new_task);                                                         Exit program                                                  Alarmmanager mgr = (alarmmanager) getsystemservice (context.alarm_service);            Mgr.set (ALARMMANAGER.RTC, System.currenttimemillis () +                    restartintent);//1 seconds after restart application                   system.exit (0);        }

But you have to say that you have to add an exception callback interface to the application OnCreate function:

Thread.setdefaultuncaughtexceptionhandler (this);

Finally, you have to change this sentence into your own application in the Androidmanifest.xml:

<application
Android:name= "Com.founder.reader.ReaderApplication"

Well, with the above global exception handling, there is no use of the so-called main function of the ability to achieve. At the same time, the program will no longer prompt "XXX software stop Execution".

Finally: The program restarts with the system clock to restart, or the program exits, who will run the restart task:

Alarmmanager mgr = (alarmmanager) getsystemservice (Context.alarm_service); Mgr.set (ALARMMANAGER.RTC, System.currenttimemillis () + restartintent); Restart the app after 1 seconds
