生成签名的 APK 时，没有文件被输出。如下所附的 gradle 构建日志中没有错误，所以我不知道从哪里开始解决这个问题。
这是一段展示该现象的视频:https://www.youtube.com/watch?v=AuZvSRXe-b0
这是 gradle 控制台日志:
Executing tasks: [:app:assembleRelease]
Parallel execution with configuration on demand is an incubating feature.

最佳答案
我使用 gradle 脚本将发布 apk 组装到目标路径。 这是代码:
android {
applicationVariants.all{ variant->
variant.outputs.each { output->
if(variant.buildType.name.equals('release')){
output.outputFile = new File('/Users/yourname/Desktop/', ’myapk.apk')
}
}
}
}
关于java - 生成签名的 APK 输出没有文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37364330/
