I solved it using PDFViewer library PDFViewer All you need to do is to:

• Import PDFViewer project to your workspace (or use PDFViewer. jar file).
• Add it as library for your project.

• Define an Activity like follows:

   public class ViewerActivity extends PdfViewerActivity { 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; } 

  }

• Call Activity like follows:

   Intent intent = new Intent(this, MainActivity.class); intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, FILE_PATH); startActivity(intent); 

Where FILE_PATH is pdfFileLocation on your device. Mine was like

final String FILE_PATH = Environment.getExternalStorageDirectory().getAbsolutePath() + "/test/com_handbook.pdf"; 

Hope this helps.
