第三方jar引用Character.UnicodeScript，androi.jar和jdk都有这个方法，理论上，第三方jar应该使用的是jdk里的Character.UnicodeScript，但我在studio中使用第三方jar时，可能调用了android.jar里的Character.UnicodeScript。在运行的时候报错java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/Character$UnicodeScript;
具体报错如下：
java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/Character$UnicodeScript;
