稍后编辑：我认为它与java版本有关，但我不知道如何更新我的android工作室？

后来编辑2：我想通了，我的计算机和最新的android工作室安装了较旧的jdk版本，感谢您的帮助。我只需要安装最新的jdk版本（8）

Answer 1

build.gradle中的

（模块：app）原样：buildToolsVersion＆＃34; 24.0.0＆＃34; 要：buildToolsVersion＆＃34; 23.0.3＆＃34;

参考：https://developer.android.com/studio/releases/build-tools.html [Build Tools，Revision 23.0.3（2016年3月）]
