ANDROID_ Program unhandled exception capture and processing

1. Brief introduction

An uncaught exception that is thrown by the program can cause the program to exit unexpectedly, the interface is unfriendly, and a critical error message should be logged to the server.

The main use of Uncaughtexceptionhandler here

2. Code implementation

public class Crashhandler implements Uncaughtexceptionhandler {public static final String TAG = Copyofcrashhandler.class. Getsimplename ();//system default Uncaughtexception processing class private Thread.uncaughtexceptionhandler mdefaulthandler;private static Copyofcrashhandler instance;private Context mcontext;private copyofcrashhandler () {}/** Get Crashhandler instance, Singleton mode */ public static Copyofcrashhandler getinstance () {if (instance = = null) instance = new Copyofcrashhandler (); return instance; }/** * Initialize */public void init (context context) {Mcontext = context;//record the default Uncaughtexceptionhandlermdefaulthandler = Thre Ad.getdefaultuncaughtexceptionhandler ();//thread.setdefaultuncaughtexceptionhandler (this);} /** * When uncaughtexception occurs, it is transferred to the function to process */@Overridepublic void uncaughtexception (thread thread, Throwable ex) {if (! HandleException (thread, ex) && Mdefaulthandler! = null) {// Let the system default exception handler handle mdefaulthandler.uncaughtexception (thread, ex) if the user does not handle it;} else {try {thread.sleep (+);} catch (Interruptedexception e) {e.Printstacktrace ();} Android.os.Process.killProcess (Android.os.Process.myPid ()); System.exit (1);}} /** * self-defined error handling, collect error messages to send error reports and other operations are complete here. * * @param ex * @return true: It is assumed that the exception information was processed; otherwise, false is returned. */private boolean handleexception (thread thread, Throwable ex) {if (ex = = null) {return false;} StringBuffer sb = new StringBuffer () sb.append (thread + ", cause by:" + ex). Append ("\r\n\r\n"); stacktraceelement[] elements = Ex.getstacktrace (); for (int i = 0; i < elements.length; i++) {Sb.append (elements[i].tost Ring () + "\ r \ n"); Record key error messages, can be saved locally and uploaded to Server//logutil.bug (TAG, sb.tostring ());//Open new Activity friendly interface prompt//util.showdialog (mcontext, "time : "+util.formatsimpledateandtime (New Date ())," The program is abnormal, please record the time and prompt the developer! "); return true;}}
