What Are the Possibilities to Read And Edit Sdcard PDF File within?

What are the possibilities to read and edit sdcard pdf file within android application? I

I've simply done that using PdfViewer.jar (download it with the blue button) and making a code like below. First.java @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); File images = Environment.getExternalStorageDirectory ; imagelist = images.listFiles(new FilenameFilter { public boolean accept(File dir, String name) { return ((name.endsWith(".pdf"))); } }); pdflist = new String[imagelist.length]; for(int i = 0;i(this,android.R.layout.simple_list_item_1, pdflist)); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); String path = imagelist[(int)id].getAbsolutePath ; openPdfIntent(path); } private void openPdfIntent(String path) { try { final Intent intent = new Intent(First.this, Second.class); intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, path); startActivity(intent); } catch (Exception e) { e.printStackTrace ; } } Second.java public class Second extends PdfViewerActivity { @Override public void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); } public int getPreviousPageImageResource { return R.drawable.left_arrow; } public int getNextPageImageResource { return R.drawable.right_arrow; } public int getZoomInImageResource { return R.drawable.zoom_in; } public int getZoomOutImageResource { return R.drawable.zoom_out; } public int getPdfPasswordLayoutResource { return R.layout.pdf_file_password; } public int getPdfPageNumberResource { return R.layout.dialog_pagenumber; } public int getPdfPasswordEditField { return http.//R.id.etPassword; } public int getPdfPasswordOkButton { return http.//R.id.btOK; } public int getPdfPasswordExitButton { return http.//R.id.btExit; } public int getPdfPageNumberEditField { return http.//R.id.pagenum_edit; } } Hope this helps you lot. Try this. Don't forgot to add your Second.java in your manifest. Add some drawables whatever it requires in second.java with your drawables. And, Refer the example fromGitHub Cheers!
