我在android中导入了一个示例代码，名为“Camera2Basic” 但我将其重命名为CameraSampleApp，因此在构建完成后我尝试运行它并弹出此错误。我做错了什么，或者我的Android Studio已经过时了。

Answer 1

解决该问题的智能方法是使用最新的SDK进行编译，并在编译时使用cross compilation options。要完全正确使用选项，需要目标版本的JRE（非JDK ）的rt.jar。

鉴于该applet的性质，它看起来可以编译为与Java 1.1一起使用。

Answer 2

我建议将multiDexEnabled添加到build.gradle文件中

defaultConfig {
    multiDexEnabled true
}

Answer 3

卸载旧的jdk并安装最新的jdk（1.8）并将JAVA_HOME的环境变量路径更改为最新的jdk。在android studio中将java路径更改为最新的jdk。
