I am using PDF Viewer Library to view PDF inside an Android app. I've browsed through a lot of tutorials, one of which is Dipak's tutorial. I want to access a PDF file stored in my assets folder instead of accessing the external storage. My problem is, I can't get the "path" right. It always return file not found.

I've tried the following, still yields the same result:

  • this.getAssets()
  • file:///android_assets/file_name.pdf
  • file:///android_asset/file_name.pdf

You can't get path from asset, have to right in sd or internal memory to get the path.

For SD Card

First Take Permission

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

then write it in card

 File f = new File(Environment.getExternalStorageDirectory() + "file.pdf");
  if (!f.exists()) try {

    InputStream is = getAssets().open("file.pdf");
    int size = is.available();
    byte[] buffer = new byte[size];
    is.read(buffer);
    is.close();


    FileOutputStream fos = new FileOutputStream(f);
    fos.write(buffer);
    fos.close();
  } catch (Exception e) { throw new RuntimeException(e); }

  Staring path = f.getPath();

  • `File f = new File("Directory Where you want to place " +"/file.pdf");` will return file not found. since the file hasn't been written to the directory – Yukai Jul 21 '13 at 15:29
