Animating the Answer | Challenge not working? | correct answer as not valid..

Hi, I'm getting the following errors: JavaTester.java:1: package android.widget does not exist import android.widget.TextView; ^ JavaTester.java:2: package android.view.animation does not exist import android.view.animation.AlphaAnimation; ^ JavaTester.java:3: package android.view does not exist import android.view.View; ^ JavaTester.java:12: cannot find symbol symbol : class View location: class JavaTester private static View findViewById(int id) { ^ JavaTester.java:24: cannot find symbol symbol : class AlphaAnimation location: class JavaTester private static void setAnimation(AlphaAnimation animation) { ^ JavaTester.java:15: cannot find symbol symbol : class TextView location: class JavaTester return new TextView(); ^ JavaTester.java:38: cannot find symbol symbol : class TextView location: class JavaTester TextView statusLabel = (TextView) findViewById(R.id.statusLabel); ^ JavaTester.java:38: cannot find symbol symbol : class TextView location: class JavaTester TextView statusLabel = (TextView) findViewById(R.id.statusLabel); ^ JavaTester.java:39: cannot find symbol symbol : class AlphaAnimation location: class JavaTester AlphaAnimation fadeOutAnimation = new AlphaAnimation(1,0); ^ JavaTester.java:39: cannot find symbol symbol : class AlphaAnimation location: class JavaTester AlphaAnimation fadeOutAnimation = new AlphaAnimation(1,0); ^ JavaTester.java:46: cannot find symbol symbol : class TextView location: class JavaTester if (TextView.class.isInstance(statusLabel) && AlphaAnimation.class.isInstance(fadeOutAnimation)) { ^ JavaTester.java:46: cannot find symbol symbol : class AlphaAnimation location: class JavaTester if (TextView.class.isInstance(statusLabel) && AlphaAnimation.class.isInstance(fadeOutAnimation)) { ^ 12 errors

The only thing it asks to do is to set a duration to the fadeOutAnimation as 2 seconds. I used the following code:

AlphaAnimation fadeOutAnimation = new AlphaAnimation(1,0); fadeOutAnimation.setDuration(2000); is that wrong?

Hi Alo,

Thanks for posting this, and sorry for any inconvenience this may have caused.

We're in the process of rolling out some improvements to our code-challenge system to provide more reliablility and faster feedback on code submissions, and we've been running the new system in tandem with the old system tonight for testing before taking it live.

It looks like some of the challenges may have been having some trouble on the new system, so we shut them down while we investigated. This issue should be fixed now, and I confirmed I was able to pass the challenge with your provided code sample.

Thanks again for bringing this to our attention, and happy coding!

Regards,

Nathan W
