Error running ‘app’ The application could not be installed. Installation failed due to: ‘Error code: ‘UNKNOWN’, message=‘Unknown failure: ‘Error: APK content must be streamed’’’ List of apks: 出现这个问题的可能的解决办法

今天遇到一个奇葩的报错

更新了android studio，导入原来的一个项目，更新了下gradle的版本，结果安装app的时候报错

Error running ‘app’ The application could not be installed. Installation failed due to: ‘Error code: ‘UNKNOWN’, message=‘Unknown failure: ‘Error: APK content must be streamed’’’ List of apks:
试了各种办法都不行，最后发现是app名称的问题，我在build.gradle里面设置了下输出的apk的名称：
android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = “my test” + variant.versionName +“-”+ releaseTime() + “.apk”
}
}
在新的android studio版本中app名称不允许有空格所以把my test改成my_test就可以了。
