 2 | =========
 3 | 
 4 | NOTE : I have discontinued support for this project. It is provided as it basis.
 5 | A ppt viewer library, which can be easily used in any existing android application.
 6 | 
 7 | Hello folks,
 8 | I was working on a project for wireless presentation and i need to embedd a PPT viewer in it.
 9 | I searched for some existing library but found none of them to be developer friendly.
10 | So here is a custom library made by me for seamless integration of a PPT viewer in any existing application.
11 | 
12 | All you need to do is:
13 | 
14 | 1. Download the library of mine (of course from GitHub).
15 | 
16 | 2. Somehow add it to your existing app, that can be done in any ways.<br/>
17 |       a. Copy and Paste it in a folder named as "libs" in your project root directory.<br/>
18 |       b. Add it to your build path by right clicking on your project and "Configure build ......."<br/>
19 | 
20 | 3. You must be having an Activity and an XML file for it.
21 | 
22 | 4. Now open the layout XML file and add the following line of code in it.<br/>
23 |       < com.itsrts.pptviewer.PPTViewer<br/>
24 |       android:id="@+id/pptviewer"<br/>
25 |       android:width="match_parent"<br/>
26 |       android:height="match_parent"<br/>
27 |       /&gt;
28 | 
29 | 5. Goto the main activity file which will be inflating the above XML and after the "setContentView", add:<br/>
30 |       PPTViewer pptViewer = (PPTViewer) findViewById(R.id.pptviewer);<br/>
31 |       pptViewer.setNext_img(R.drawable.next)<br/>
32 |                   .setPrev_img(R.drawable.prev)<br/>
33 | 	            .setSettings_img(R.drawable.settings)<br/>
34 | 			.setZoomin_img(R.drawable.zoomin)<br/>
35 | 			.setZoomout_img(R.drawable.zoomout);<br/>
36 |       pptViewer.loadPPT(activity, path);<br/>
37 |       // path is a String having the location of the ppt file to be loaded.<br/>
38 | 
39 | The library is fully customizable with the option to change the viewer the way you want.
