Cause: need sign apk but apksigner *\Sdk/build-tools/28.0.2/apksigner was not exist

[dede1314]

window发现这个问题，不过已经有解决方案。 https://blog.csdn.net/zhangphil/article/details/89509787 window的apksigner需要加.bat

首先感谢提出问题和建议。其实这里是有原因的： 虽然我们的demo是运行在mac平台的，但当时也是考虑到windows的，事实上我们期望由用户来改变这个变量的值，因为每台机的签名包路径都可能不一样。 我们加一行注释吧，给出参考的值再提醒一下自己要check一遍 再次感谢。

mac上同样存在这个问题。 检查apksigner的路径是存在的。 org.gradle.api.GradleException: need sign apk but apksigner /Users/tyoshi/Library/Android/sdk/build-tools/28.0.2/apksigner was not exist! at

在windows下编译，app/build.gradle 下修改成这样，避免windows下的反斜杠路径分隔符

import java.nio.file.Paths

// apksingerPath 和 zipAlignPath对应行修改成如下拼接路径
apksignerPath = Paths.get("${android.getSdkDirectory().getAbsolutePath()}", "build-tools", "${android.getBuildToolsVersion()}", "apksigner.bat")
zipAlignPath = Paths.get("${android.getSdkDirectory().getAbsolutePath()}", "build-tools", "${android.getBuildToolsVersion()}", "zipalign.exe")
