Drag and drop operation in appium

Some important points

1. TouchAction and MultiTouchAction class can be used to do drag and drop operation
2. press, waitAction and moveTo methods should be called in sequence to perform drag and drop
3. We can find the Point of Source and Destination element using getLocation method
4. Finally perform method of MultiTouchAction class can be used to perform drag and drop action
5. Swiping specific element is same as drag and drop operation. Only difference is that we do not have destination element. In this case, we can use destination point.
6. In same way, we can do this action in iOS as well

Below hypothetical code demonstrates how you can perform drag and drop action in Android Emulator. Here we are assumming that battery element can be dragged to sound element. You need to replace these elements with the ones in your app.
