Java Android中的动态类加载
我想将功能注入我的android应用程序。 然而，我一直在遭受“java.lang.ClassNotFoundException”的痛苦。 我错过了什么Java Android中的动态类加载,java,android,Java,Android,我想将功能注入我的android应用程序。 然而，我一直在遭受“java.lang.ClassNotFoundException”的痛苦。 我错过了什么 简单类（只是一个.class文件） 布局和资源 活动 首先我想做1。 但是有很多方法可以实现，我不知道如何实现这一点 假设： 1.文件下载到本地数据存储库中 2.targetClassName是com.example.mari.myandroid.TestDinamicLoad 3.SDK和构建工具版本（无proguard） 编译DK22版 B
