         }
         in.close();
         page = sb.toString();
         } finally {
         if (in != null) {

    if(v == addResumeFromUrlBtn)
    {   
        try {
            resume = readPDF();             
        } catch (Exception e) 
        {
            e.printStackTrace();

        txt.setDrawingCacheEnabled(true);
         txt.setText(resume);   
        txt.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), 
                  MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        txt.layout(0, 0, txt.getMeasuredWidth(), txt.getMeasuredHeight());          
        txt.setDrawingCacheEnabled(false);           
        l.addView(txt);         
    }
}
}

            File file = new File(fileLocation);    

            if (file.exists()) {
                Uri path = Uri.fromFile(file);
                Intent intent = new Intent(Intent.ACTION_VIEW);    //Set Intent action view pdf file
                intent.setDataAndType(path, "application/pdf");      //Set data type
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);    

                try {
                    startActivity(intent);                          //Start Activity
                } catch (ActivityNotFoundException e) {
                    Toast.makeText(OpenPdf.this,
                            "No Application Available to View PDF",
                            Toast.LENGTH_SHORT).show();

First of there is no support for pdf in Android so you need to open in some other app like adob or if you want to do it right way then need make the load lib like vudroid and apdfviewer .

apdfviewer is very good but there is no support how to compile source code, actually all lib work with c++ in backend so you need to install the ndk.

Vudroid is slow but you can compile easily.

I hope this will help you.
