我是新手,已经成功安装它并在一台机器上工作,但是在这台机器上工作时,我遇到了一些问题。这是android studio,flutter和gradle的全新安装。机器正在运行更新的Windows 10。
Flutter Doctor语句在检索设备属性时返回错误。

尝试在模拟的android实例或真实设备上运行flutter应用程序时,出现相同的错误:

因此,在努力使程序正常运行并进行了更多搜索之后,我找到了解决我遇到的两个问题的解决方案。
第一个问题是,除非studio.bat正在运行,否则android studio不会运行,这是通过在Windows安全设置中禁用ASLR来解决的。(studio.exe / studio64.exe)
第二个问题是它无法检索设备属性,这是通过在adb上禁用堆保护来解决的。(adb.exe)
