How to use this lib?

1. Setting up environment

a) Import library b) Set app permission c) Register receiver to “SmsReceiver”

2. Creating your own “Executor”

a) Flow chart of message passing b) Implement “Executor” and recommended style

3. Using “Recorder” and “CommandHandler”

a) Initialize at the beginning of the program b) Accessing database via “Recorder” c) Add implemented executors

4. Invoke Executor

a) Usual condition b) Dealing with asynchronous condition
