DocumentReader

This library reads word documents (.doc and .docx), txt and PDF files, and gives the output content of the document as a String.

If you have ever tried to read contents of a PDF or MS word document on Android, you know how painful it is. This library makes your work easy.

How to use it?

// Read a pdf file from Uri
val docString : String = DocumentReaderUtil.readPdfFromUri(fileUri, applicationContext)
// Read a pdf file from File
val docString : String = DocumentReaderUtil.readPdfFromFile(file, applicationContext)

// read a doc file from Uri
val docString : String = DocumentReaderUtil.readWordDocFromUri(fileUri, applicationContext)
// read a doc file from File
val docString : String = DocumentReaderUtil.readWordDocFromFile(file, applicationContext)

// read a docx file from Uri
val docString : String = DocumentReaderUtil.readWordDocFromUri(fileUri, applicationContext)
// read a docx file from File
val docString : String = DocumentReaderUtil.readWordDocFromFile(file, applicationContext)

// read a txt file from Uri
val docString : String = DocumentReaderUtil.readTxtFromUri(fileUri, applicationContext)

/*
 Even if you don't know your file type, 
 this library detects the file mime type and gives you the content of the file as a String
*/
val docString : String = when (DocumentReaderUtil.getMimeType(fileUri, applicationContext)) {
        "text/plain" -> DocumentReaderUtil.readTxtFromUri(fileUri, applicationContext)
        "application/pdf" -> DocumentReaderUtil.readPdfFromUri(fileUri, applicationContext)
        "application/msword" -> DocumentReaderUtil.readWordDocFromUri(fileUri, applicationContext)
        "application/vnd.openxmlformats-officedocument.wordprocessingml.document" -> 
                                        DocumentReaderUtil.readWordDocFromUri(fileUri, applicationContext)
         else -> ""
	 }
