Java/android: combining two libraries, android file layout?
<p>I'm using two libraries in an android app I'm trying to make. New to android. The app is for connecting to serial devices and controlling their console via a terminal. </p>

<p>One library is for setting up a serial connection, setting baud rate etc and can also write read/data over serial.. The other is for creating a terminal session. I have no problem running these libraries to get simple separate examples up and running. Eg, with the first library I can set up a serial connection with a router and send/receive data via textboxes which looks like this:</p>

<p><a href="https://lh5.ggpht.com/R4CAJXY9ZPDVsgt8jUZg5hc-v81aa70sctiegIGDjzv2lyvuG6OZyYas_4I-h_es-4Aq" rel="nofollow">https://lh5.ggpht.com/R4CAJXY9ZPDVsgt8jUZg5hc-v81aa70sctiegIGDjzv2lyvuG6OZyYas_4I-h_es-4Aq</a></p>

<p>With the second library I am able to set up local terminal on a tablet and look at the directories etc. My problem lies in incorporating both of these together to have a terminal that is connected to a serial device and with the layout/passing of data.</p>

<p>In the terminal library I need to supply an InputStream and OutputStream to provide input and output to the terminal. So I have to call setTermIn(java.io.InputStream) and setTermOut(java.io.OutputStream) to connect the input and output streams to the emulator.</p>

<p>In the serial library however there are two methods for sending and receiving and these deal with arrays of bytes. 
sendData(byte[] data) for sending data and a dataListener for receiving data. I have to implement this and code the method onDataReceived(int id, byte[] data) with id being the name of the device.</p>

<p>So my question is, how do I hook these up? Do I create java.io.InputStream/OutputStream implementations on top of sendData and OnDataReceived, just convert the arrays to streams and call the setTermIn/Out methods?</p>

<p>For OnDataReceived I suppose all I do is receive the byte[] data and convert it to a stream inside the method and send this to the terminalActivity?
but what about sendData, I am not implementing this, I just send an array of bytes, how do I send it as a stream instead to setTermIn?</p>

<p>I am also very confused about having these things happening in different activities and how that works. Because I have the serial stuff happening in one activity, so I hit connect, it reads the relevant baud rate etc and connects to the serial device, then a terminal is opened in a new terminalActivity which is currently connected to nothing, just looks like a blank terminal. I'm not sure how everything should be laid out. Like if I hit the enter key in a terminal, should the implementation for sending data over serial not be in that same activity, not the one I am initially in where I am connecting to a serial device? But to know if I am connected to a serial device in the first place I need to send/receive data...should there be implementations of these methods in both activities?! Or maybe I should simplify it and add the connection options and the terminal to the same activity?</p>

<p>Should I be combining these both in one activity maybe?</p>
