由于某种原因在棒棒糖,我得到这个错误,因为棒棒糖是如此新的我无法找到为什么在任何地方,我不知道如何弄明白.在此先感谢Logcat错误:

编辑:这是导致错误的代码

    title = (TextView) findViewById(R.id.title);


    Typeface font = Typeface.createFromAsset(getAssets(), "helvetica.ttf");
    title.setTypeface(font);

我的项目文件夹中的assets文件夹中有helvetica.ttf.

编辑:此应用程序适用于所有设备,直到5.0,所以由于某种原因5.0 5.0无法识别我的资产文件夹中的文件.

我试图在我的资源文件夹中发布它的截图,但我没有足够的声誉来发布图像.
