PKIX path building failed: unable to find valid certification path to requested target

AndroidStudio报错PKIX path building failed: unable to find valid certification path to requested target 解决方案：

从错误提示来看:找不到可用证书**。**Android Studio没有获得使用网络的权限，无法访问https://bintray.com/bintray/jcenter。

解决步骤：

1.终极方案:从https://bintray.com/bintray/jcenter获取证书。

第一步，下载狐火浏览器。

第二步，打开https://bintray.com/bintray/jcenter

2.打开之后，可以看到地址栏有一把锁，点开：

3.继续点击更多信息（可能火狐版本不一样，界面会有点不同，如果实在不会，请在“恬恪学习网”关于我们，与我们客服协助）

4.查看其证书：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3BrNjk0MDQ2MjIw_size_16_color_FFFFFF_t_70 2

5.将证书导出，记住自己导出的位置地方：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3BrNjk0MDQ2MjIw_size_16_color_FFFFFF_t_70 3

6.在AndroidStudio中，找到Server Certificates 将证书导入：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3BrNjk0MDQ2MjIw_size_16_color_FFFFFF_t_70 4

7.重启并清理缓存，这一步必做：

8.将gradle文件改成这样：
