Just identify that your Application is being launched after it was previously destroyed by Android, you could do this by keeping a variable in a custom Application class, and set it to true after your applicaiton is initialized. So when the applicaction is re-launched, this flag is false, and then just make an Intent to launch your main Activity specifying FLAG_ACTIVITY_CLEAR_TOP :

Intent reLaunchMain=new Intent(this,MainActivity.class);
reLaunchMain.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(reLaunchMain);
