As @Reto Koradi said there is no way to do it but you can store the width and height of a texture when you are loading it from android context before you bind it in OpenGL.

    AssetManager am = context.getAssets();
    InputStream is = null;
    try {
        is = am.open(name);
    } catch (IOException e) {
        e.printStackTrace();
    }
    final Bitmap bitmap = BitmapFactory.decodeStream(is);
    int width = bitmap.getWidth();
    int height = bitmap.getHeight();

    // here is you bind your texture in openGL
