Bye Bye ANR in Android.
It’s not a good practice to restart the application forcefully. We should try to catch exception wherever possible. However, android provide a way to perform certain intent whenever there is some exception occurred in the application that is not caught in the try-catch block.
The handler works the current thread on which it is being added. We can add the custom exception handler on a thread in the following manner:
|
1 2 3 |
Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this, SplashScreenActivity.class)); |
Here is an Exception handler class that implements java.lang.Thread.UncaughtExceptionHandler.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |
package com.webkul.mobikul.helper; import android.content.Context; import android.content.Intent; import android.os.Process; import java.io.PrintWriter; import java.io.StringWriter; public class MyExceptionHandler implements java.lang.Thread.UncaughtExceptionHandler { private final Context myContext; private final Class<?> myActivityClass; public MyExceptionHandler(Context context, Class<?> c) { myContext = context; myActivityClass = c; } public void uncaughtException(Thread thread, Throwable exception) { StringWriter stackTrace = new StringWriter(); exception.printStackTrace(new PrintWriter(stackTrace)); System.err.println(stackTrace);// You can use LogCat too Intent intent = new Intent(myContext, myActivityClass); String s = stackTrace.toString(); //you can use this String to know what caused the exception and in which Activity intent.putExtra("uncaughtException", "Exception is: " + stackTrace.toString()); intent.putExtra("stacktrace", s); myContext.startActivity(intent); //for restarting the Activity Process.killProcess(Process.myPid()); System.exit(0); } } |
Stay updated !!
