62, when the app encountered a global exception to avoid direct exit, how to let the app take over exception handling?

1. Create a class for Crashhandler

1 ImportAndroid.content.Context;2 ImportAndroid.os.Looper;3 ImportAndroid.util.Log;4 ImportAndroid.widget.Toast;5 6 ImportJava.text.DateFormat;7 ImportJava.text.SimpleDateFormat;8 ImportJava.util.Locale;9 Ten /** One * author:created by Zzl on 15/11/3. A  */ -  Public classCrashhandlerImplementsThread.uncaughtexceptionhandler { -     Private Static FinalString TAG = Crashhandler.class. Getsimplename (); the  -     Private StaticCrashhandler instance;//single-case mode -  -     PrivateContext context;//Program Context Object +     PrivateThread.uncaughtexceptionhandler Defaluthandler;//system default Uncaughtexception processing class -     PrivateDateFormat formatter =NewSimpleDateFormat ( +"Yyyy-mm-dd_hh-mm-ss.sss", Locale.china); A  at     PrivateCrashhandler () { -  -     } -  -     /** - * Get Crashhandler instances in      * -      * @returnCrashhandler to      */ +      Public StaticCrashhandler getinstance () { -         if(Instance = =NULL) { the             synchronized(Crashhandler.class) { *                 if(Instance = =NULL) { $Instance =NewCrashhandler ();Panax Notoginseng                 } -             } the         } +  A         returninstance; the     } +  -     /** $ * Initialization of exception handling $      * -      * @paramContext -      */ the      Public voidinit (Context context) { -          This. Context =context;Wuyi         //get the system default Uncaughtexception processor theDefaluthandler =Thread.getdefaultuncaughtexceptionhandler (); -         //set the Crashhandler as the default processor for the program WuThread.setdefaultuncaughtexceptionhandler ( This); -     } About  $     /** - * When uncaughtexception occurs, it is transferred to the function to handle -      */ - @Override A      Public voiduncaughtexception (thread thread, Throwable ex) { +  the         //Custom error Handling -         Booleanres =HandleException (ex); $         if(!res && Defaluthandler! =NULL) { the             //let the system default exception handler handle if the user does not handle the defaluthandler.uncaughtexception (thread, ex); the  the}Else { -             Try { inThread.Sleep (3000); the}Catch(interruptedexception e) { theLOG.E (TAG, "Error:", e); About             } the             //Exit Program the             //android.os.Process.killProcess (Android.os.Process.myPid ()); the             //system.exit (1); +         } -     } the Bayi     /** the * Custom error handling, collect error messages to send error reports and so on are done here. the      * -      * @paramex -      * @returntrue: Returns False if the exception information is processed; the      */ the     Private BooleanHandleException (FinalThrowable ex) { the         if(ex = =NULL) { the             return false; -         } the  the         NewThread () { the 94 @Override the              Public voidrun () { the Looper.prepare (); the 98 ex.printstacktrace (); AboutString err = "[" + ex.getmessage () + "]"; -Toast.maketext (Context, "The program has an exception.")err, Toast.length_long)101 . Show ();102 103 Looper.loop ();104             } the 106 }.start ();107 108         //collecting device parameter information \ Log information109         return true; } the}

2, in the Application OnCreate () in the case of the change Crashhandler

1     @Override 2      Public void onCreate () {3         Super . OnCreate (); 4         initinformdata (); 5         Mcontext = getapplicationcontext (); 6         Crashhandler Crashhandler = crashhandler.getinstance (); 7         Crashhandler.init (mcontext); 8 9     }

This way, when the app encounters an uncaught exception, it does not flash directly, depending on how the developer handles the business needs.
