How do I tell if Intent extras exist in Android?

Question

I have this code that checks for a value of an extra in an Intent on an Activity that is called from many places in my app:

getIntent().getExtras().getBoolea         


        

Answer 1

It will not crash unless until you use it! You don't have to get it if it exists but if you try, for some reason, to use a an "extra" which doesn' exists your system will crash.

So, try o do something like:

final Bundle bundle = getIntent().getExtras();

boolean myBool=false;

if(bundle != null) {
    myBool = bundle.getBoolean("isNewItem");
}

This way you make sure your app won't crash. (and make sure you have a valid Intent :))
