Parsed in 0.060 seconds,  using GeSHi 1.0.8.4

I m getting errors at two places

1) rQueue.waitUntilComplete()

The method waitUntilComplete() is undefined for the type RequestQueue

2)nm.notifyWithText(RANDOM_ID, msg, NotificationManager.LENGTH_LONG, null);

NotificationManager.LENGTH_LONG cannot be resolved
