"Native typeface cannot be made" only for some people

This bug of Android OS could be the reason of your issue:

Typeface.createFromAsset leaks asset stream

Where are also a workaround in this bugreport:

I altered HTH's workaround so that the method does not assume the font path or format. The full path of the font asset must be submitted as a parameter. I also wrapped the call to createFromAsset() in a try-catch block so that the get() method will return null if the asset is not found.

public class Typefaces {    private static final String TAG = "Typefaces";    private static final Hashtable<String, Typeface> cache = new Hashtable<String, Typeface>();    public static Typeface get(Context c, String assetPath) {        synchronized (cache) {            if (!cache.containsKey(assetPath)) {                try {                    Typeface t = Typeface.createFromAsset(c.getAssets(),                            assetPath);                    cache.put(assetPath, t);                } catch (Exception e) {                    Log.e(TAG, "Could not get typeface '" + assetPath                            + "' because " + e.getMessage());                    return null;                }            }            return cache.get(assetPath);        }    }}

I followed some of the solutions found here, with no success. I thought it was something really obscure, as programmers often do. Then somewhere I read it could be related to the font path, gotcha:

Instead of:

Typeface phoneticFont = Typeface.createFromAsset(getAssets(),                                             "blanch_caps.ttf");   

I changed to:

Typeface phoneticFont = Typeface.createFromAsset(getAssets(),                                             "fonts/blanch_caps.ttf");   

And my file is in assets/fonts/blanch_caps.ttf. Not it works like a charm!

This error came up when the font was in the library asset folder. When I copied it into assets of the application which was using this library, the error disappeared.

It seems assets cannot be imported:Android Library assets folder doesn't get copied

And here are some other cases: Issue when using a custom font - "native typeface cannot be made"
