Android: How to open PDF without using the internet?

Question

How do I place a file .pdf on its own app, and open it without downloading using its URL? It would be all offline. Once the app was installed, .pdf would go along with him.

Answer 1

Android has no support for PDF format, so it is necessary to use external libraries. A widely used is the Androidpdfviewer.

Below follows the step by step to use it

1) Add Pdfviewer.jar into your project’s build path

2) Copy the following drawable Resources from Pdfviewer/res/drawable into Yourproject/res/drawable left_arrow.png right_arrow.png zoom_in.png zoom_out.png

3) Copy the following layout Resources from Pdfviewer/res/layout into Yourproject/res/layout dialog_pagenumber.xml pdf_file_password.xml

4) Derive your PDF Activity from net.sf.andpdf.pdfviewer.PdfViewerActivity

5) Using the default drawables and layouts: 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 R.id.etPassword; } public int getPdfPasswordOkButton() { Return R.id.btOK; } public int getPdfPasswordExitButton() { Return R.id.btExit; } public int getPdfPageNumberEditField() { Return R.id.pagenum_edit; }

6) Invoke your Pdfviewactivity derived with the following code: Intent Intent = new Intent(this, Yourpdfvieweractivity.class); Intent.putExtra(Pdfvieweractivity.EXTRA_PDFFILENAME, "PATH TO PDF GOES HERE"); startActivity(Intent);
