Questions tagged [android-os-handler]

A Handler allows you to send and process Message and Runnable objects associated with a thread's MessageQueue. Each Handler instance is associated with a single thread and that thread's message queue. When you create a new Handler, it is bound to the thread / message queue of the thread that is creating it - from that point on, it will deliver messages and runnables to that message queue and execute them as they come out of the message queue.
