how I can get a field (text area) from my database and read it as a pdf
What do you mean, to retrieve a text value and read it as pdf?
If you read values from a database at the most you can use these values to generate a pdf through a library like PDFBox, IText or GlobalReports

You can use

And specify the row numbers and column numbers accordingly.

I have a text file like below
Shipto: abc def Soldto: XYZ EFG From: JANGO
Shipto addr Soldto addr FromAddr
PO - 1000 PO-2000 PO-3000
I need to parse this file and store the ship to, sold to and from addresses to DB using Java. Any idea how to achieve this?
Try using a scanner to read the txt file and store it in a String. You could then parse the String and store it in a DB.

I want to convert GIF file to video file, I searched for it but couldn't find any library for it. Does any one know how to do it ?
There is library android-ffmpeg
In short, there is method in FfmpegController called convertImageToMP4 (Clip mediaIn, int duration, String outPath, ShellCallback sc). I think it should do, what you want.
Also, please, see this answer for more details.

Is there a way I can set a listener for if the TextArea is edited by the user?
If that is not possible, can I add one to its focus?
Get the document the text area is using via textArea.getDocument()
Then write a document listener. The document listener will tell you whenever the user edits the text area.
