It is possible yes. You can see performance improvements in many situations if the construction of a new object is expensive (like establishing a database connection) or if for other reasons the GC bandwidth is too high (often a problem in Android-land).

Here are some resources that you could use to implement your pool. You may be able to use Apache's ObjectPool right out of the box.
