主要是重写 onCreate 方法

public class App extends Application {

    public static String SD = Environment.getExternalStorageDirectory().toString();

    //音节部分
    public static String SHENGMU_SOUND = SD + "/tolisten/0/0/";
    public static String YUNMU_SOUND = SD + "/tolisten/0/1/";
    public static String ZHENGTIRENDU_SOUND = SD + "/tolisten/0/2/";
    public static Typeface YOUYUAN;

    @Override
    public void onCreate() {
        super.onCreate();
        Typeface typeface = Typeface.createFromAsset(getBaseContext().getAssets(), "fonts/youyuan.jpg");
        Log.i("xjxu", "检测是不是执行了");
        YOUYUAN = typeface;
    }
}

在 AndroidManifest 中定义

 <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        android:name=".tool.App">
