How can i parse PDF file in android?

Question

I am developing android application. This application allows the user to highlight words in PDF file. Then these words must be extracted, so how can I parse the PDF file to get extracted words from the file without any library? Can any one help me?

You have to code it yourself if you don't want to use a libary. There isn't any build-in classes in Android SDK for PDF manipulation.

However you have to use a Libary and have a look at this question:

Thank you for your replay, If I want to write code by my self , can i read the PDFfile like other text file? an how can i get the background color of the text? – user3393104 Mar 09 '14 at 22:17
You can't do that because you have to use the SDK from Adobe and that is managed code. so it would be very difficult. Why don't you want to use a library? – Jackson Mar 09 '14 at 22:19

You can parse PDF easily on android easily using the iText library as like I've done it on my project by parsing a pdf file from assets and displaying it in the android listview.

iTextG Link: https://developers.itextpdf.com/itextg-android

assetManager = getAssets();

try{
    InputStream inputStream = assetManager.open("sample.pdf");
    String parsedText = "";
    PdfReader reader = new PdfReader(inputStream);
    int n = reader.getNumberOfPages();

    for (int i = 0; i < n; i++)
        parsedText = parsedText + PdfTextExtractor.getTextFromPage(reader, i + 1).trim() + "\n";

    String[] data = parsedText.split("\n");

    for(String d : data){
        patients.add(d);
    }

    reader.close();

}catch (FileNotFoundException e){
    Toast.makeText(this, "File Not Found", Toast.LENGTH_SHORT).show();
}catch (IOException e){
    Toast.makeText(this, "IO Error reading input stream", Toast.LENGTH_SHORT).show();
}
