Does Handler execute Runnable's simultaneously
<p>A non-UI thread in my Android application contains a Handler object, and I add implementations of Runnable to this Handler using the post() method.</p>

<p>From reading the API, it seems that Handler uses a queue. Does this mean that if I post() 2 Runnables to the queue, that the second one will only start executing on completion of the first Runnable's run method?</p>

<p>Just wanted to confirm this as I am seeing some multi-threading issues in my application.</p>

<p>Thanks</p>
