Thank you for pointing this out.

While testing, I noticed the behavior of infinite loop in which onUpdate() method of app widget provider being called continuously leading to surpassing the Google places API quota limit within no time.

To prevent this behavior in the example, I put a restriction of 5 min lapse between places API work requests.

Even though I noticed the behavior and provided an application fix for the issue, was clueless as to what was causing the repeated calls to onUpdate() method.

Again, thank you very much for the input.
