我尝试按照此处的指南，为Android上的TextView使用自定义字体。使用相同的字体，相同的代码，相同的所有内容，我在adb logcat中得到此信息：

我使用的是Molot.otf字体，该字体已在其中一个博客中成功使用。我还使用predator.ttf，这是另一种自定义字体，但格式为TrueType。

相关代码：

public class MainActivity extends Activity {
    // Called when the activity is first created.
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/Molot.otf");
        TextView tv = (TextView) findViewById(R.id.CustomFontText);
        tv.setTypeface(tf);
    }
}

和

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView
        android:id="@+id/CustomFontText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="30sp"
        android:text="Here is some text.">
    </TextView>
</LinearLayout>

是什么原因造成的？它对博客中的人有用，那为什么不呢？API中是否发生了一些重大更改，从而阻止了我这样做？
