How to auto restart application after crash/force close in android

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:

Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this,

SplashScreenActivity.class));

Here is an Exception handler class that implements java.lang.Thread.UncaughtExceptionHandler.

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 !!
