我试图通过将所有活动替换为从AppCompatActivity扩展来更新项目。但我的应用程序始终不会以相同的错误开始：
java.lang.NoClassDefFoundError：android.support.v7.app.AppCompatDelegateImplV14
我尝试了什么：

解决方案/对我/：
我在一个子项目中有一个support-v4 jar，但我无法排除。所以我必须修改子项目以排除jar。
答案 0 :(得分：3)
我只排除＆＃39; support-v4＆＃39;在顶层
你要
java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV14
如果Java虚拟机或ClassLoader实例尝试，则抛出该异常 加载类的定义（作为普通方法调用的一部分或 作为使用新表达式创建新实例的一部分）和否 可以找到班级的定义。
从Build.gradle
compile project(':android-support-v4')
