Toast not showing up in UnCaughtExceptionHandler
android, toast, uncaught-exception, uncaughtexceptionhandler
Solution
You are probably calling the Toast from a thread while a toast should be called from the UI thread...
If this isn't helping, please provide us the logcat output so we can see what kind of error you are getting.
Problem
I am using this code to handle any uncaught exceptions which might cause my application to crash. ``` public class ExceptionHandler implements java.lang.Thread.UncaughtExceptionHandler { private final Context myContext; public ExceptionHandler(Context context) { myContext = context; } public void uncaughtException(Thread thread, Throwable exception) { Toast.makeText(myContext, "The application has crashed, and a report is sent to the admin", Toast.LENGTH_SHORT).show(); StringWriter stackTrace = new StringWriter(); exception.printStackTrace(new PrintWriter(stackTrace)); System.err.println(stackTrace);// You can use LogCat too Intent intent = new Intent(myContext, CrashActivity.class); myContext.startActivity(intent); Process.killProcess(Process.myPid()); System.exit(10); } } ``` When i run it with a known but uncaught exception(just to test), activity "CrashActivity" is called but the Toast which must come before it is not showing up. Actually i wanted to show only Toast and then call myContext.finish(); instead of going to the CrashActivity. But that toast in not visible. Where am i wrong?
