NDK_PROJECT_PATH=null Androidstudio安装工程出现编译问题

[jerryjjh]

最近在安装公司项目后出现编译问题：(ndk是15rc,14rb也试过)

咋没人回复啊，大神们都很忙吗？几天了，倒不进去公司项目，好郁闷。拜托好好看看，如果需要可以加q290-485-788

公司项目原来用的是什么环境呢？

[jerryjjh]

已经解决了。感觉windows系统还是不太稳定。要问咋解决的，其实，真的很戏剧。改了一圈其实最后改回原来的了，然后神奇的编译通过了。具体来说，NDK_PROJECT_PATH=null，其实就是找不到ndk相关文件，在buildgridle里面找到如下代码。发现srcdirs里面指定路径还包含了两处，相关文件在,"libmupdf/platform/java/src"。所以把前面的src/main/java“这个路径给删了，结果战战兢兢居然编译过了，但是还是一堆报错，然后，查来很多资料，发现前边的路径是代码的路径，也不能删除，又给恢复了，结果神奇的解决了。我也是一头雾水。从坑里爬了一个礼拜，绕了一大圈，还不知道咋解决的。估计是gradle版本的问题，总之不是很稳定。 sourceSets { main { java { srcDirs = ["src/main/java","libmupdf/platform/java/src"] } } }

有没有相同遭遇的朋友，解决了吗？

我也遇到这个问题了，怎么改都不行，网上都是说路径有中文和空格的问题，做程序员这都是基本常识，肯定不会有空格和中文，但是就是找不到原因，百度 google了1天还是没办法

找了一天,这个问题终于解决了,是android.mk里面的路径问题.

windows下编译mupdf,我也碰到这个问题,一模一样, 大神们有解决吗?
