I'm writing a library, which does some intensive network work. So, I'm using a HandlerThread to carry out this operation like this:

```
Looper.prepare();
libraryThread = new LibraryHandlerThread(context);
libraryThread.start();
libraryThread.getLooper();

```

LibraryHandlerThread does the network operations and other time consuming operations.

When I call this code from a worker thread (any thread other than Main thread), it works fine. But complains about "can't initialize another looper when one is already active". I believe that a Looper runs on Main thread by default, and complains about Looper.prepare(). I can do something like following to make it working from Main thread:

```
Looper.getMainLooper().quit();
Looper.prepare();
libraryThread = new LibraryHandlerThread(context);
libraryThread.start();
libraryThread.getLooper();

```

My question is: what would be the impact on Main thread. In my ideal world, I want to run my library's operations on a separate thread without impacting the main thread. How can I achieve this without much destruction?
