 4 | Android MQTT Client - Demo
 5 | 
 6 | This is a simple client to demonstrate the use of fusesource/mqtt-client library on Android.
 7 | 
 8 | Once you have cloned the repo, you can build the project in eclipse with Android SDK.
 9 | 
10 | To Build the project in eclipse:
11 | 
12 | 1) Select: File -> New -> Android Project
13 | 
14 | 2) Give the project a name
15 | 
16 | 3) Select: Create project from existing source
17 | 
18 | 4) Browse to the location where you cloned the repo
19 | 
20 | 5) Click Finish
21 | 
22 | Once the project is created you will need to add the mqtt-client lib dependency.
23 | 
24 | This can be done by cloning the fusesource/mqtt-client repo and building the project.
25 | Then add the mqtt-client uber jar to the build path.
