How to get the android Path string to a file on Assets folder?

AFAIK the files in the assets directory don’t get unpacked.
Instead, they are read directly from the APK (ZIP) file.

So, you really can’t make stuff that expects a file accept an asset ‘file’.

Instead, you’ll have to extract the asset and write it to a seperate file, like Dumitru suggests:

  File f = new File(getCacheDir()+"/m1.map");
  if (!f.exists()) try {

    InputStream is = getAssets().open("m1.map");
    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); }

  mapView.setMapFile(f.getPath());
