Question

我已经在android studio中添加了登录活动并安装了google play服务但是当我运行该程序时，我不断收到以下错误。我认为这是由于64方法问题合并多个dix文件，但解决方案不起作用。任何想法？感谢

尝试将您的构建工具从Android SDK管理器更新为比您正在使用的19.1.0更新的东西。

Answer 2

提示：检查输出并尝试在发布之前了解出现了什么问题。

查看错误说明的内容：

未知输出扩展名：E：\ year4 \ 4thYearProject \ projectCode \ Train

然后再看一下dx命令的输出参数：

C：\ Users \用户卡尔\应用程序数据\本地\的Android \机器人工作室\ SDK \构建工具\ 19.1.0 \ dx.bat --dex --num-threads = 4 --multi-dex - 输出E：\ year4 \ 4thYearProject \ projectCode \ Train＆amp; Gain \ app \ build \ intermediates \ dex \ debug E：\ year4 \ 4thYearProject \ projectCode \培训和放大器，增益\程序\编译\中间体\ Classes下\调试 E：\ year4 \ 4thYearProject \ projectCode \培训和放大器，增益\程序\编译\中间体\依赖缓存\调试 E：\ year4 \ 4thYearProject \ projectCode \培训和放大器，增益\程序\编译\ \中间体爆炸-AAR \ com.google.android.gms \播放服务\ 52年4月4日\ classes.jar C：\ Users \用户卡尔\应用程序数据\本地\的Android \ Android的工作室\ SDK \演员\机器人\ m2repository \ COM \机器人\ SUPPORT \支持-V4 \ 19.1.0 \支持，v4-19.1.0.jar E：\ year4 \ 4thYearProject \ projectCode \列车＆安培;增益\应用\构建\中间体\分解-AAR \ com.android.support \程序兼容性-V7 \ 19.1.0 \ classes.jar

你现在能看到[可能]的错误吗？看起来dx命令终止于'＆amp;'标志。将其从项目名称中删除，然后重试。

我遇到了这个错误，并将其跟踪到处理BAT文件的CMD。编辑后，它工作。构建符号％arch_ext％的 tools \ lib \ find_java.bat 中的行失败;它附加了一个尾随空格，因此 arch_ext 是＆＃34; 32＆＃34;而不是＆＃34; 32＆＃34;。当符号稍后展开时，引入的空间破坏了路径。只需在＆＃34; set＆＃34;周围添加括号即可。修复它的操作。

reg Query "HKLM\Hardware\Description\System\CentralProcessor\0"   | find /i "x86"   1>NUL  && (set arch_ext=32)  || (set arch_ext=64)
