Solution 1

That won't work for you as you're referencing the wrong context.
Instead of declaring private Context context in the anonymous implementation of Animation.AnimationListener, you should reference Context from the class that calls animlation.setAnimationListener.

For this example I'll assume your class is called MyClass, and you should then change the call from

Java

this.context.startActivity(new Intent(this.context,MyBig1.class));

to

Java

MyClass.this.context.startActivity(new Intent(MyClass.this.context,MyBig1.class));

Thanx
I had tried that even this is not working.
it crashes out as soon as reaching to new intent place.

Crashing with what type of Exception?

but, when I do the same in my application, the context is becoming null the point of startActivity(). Ultimately, the second class is not getting instantiated. I have declared my context as, " private Context context;"

I am using this in a class, that extends a FileObserver, but neither an activity, nor a service.
