Question

刚下载Android工作室并遇到一些麻烦。无法运行默认的hello world程序。似乎与API版本号和正确的链接有关？我最初的版本是20，不适用于手机。我试图改为第19版

启动 - 计算机 - 属性高级系统设置 - 环境变量读取： java_home C：程序文件/ javajdk1.8.0_20 （我也可能偶然改变了一些事情： ComSpec c：windows / system32 / cmd32）

从那里我从Android工作室下载了一些：

       SDK manager"

按API排序我拥有19的所有API 由于某种原因玻璃开发预览没有安装。我也有API 20的一些东西和usb驱动程序和存储库（rev 6） google play rev 19 google usb driver rev 10

RUN 当我点击运行...我选择nexus 7（那里唯一一个）手机屏幕打开，然后在加载时读取Android

等待设备。记录....

          "C:...\AppData\Local\Android\android-studio1\sdk\tools\emulator.exe" -avd nexus7             -netspeed full -netdelay none
       Device connected: emulator-5554

对不起我对这一切都很新，不知道发布什么。我没有触及任何默认的代码。

Answer 1

这似乎是错误的已知问题＆＃34;您无法结合滑动解雇和操作栏。＆＃34;

它告诉我们：

不要将API等级20和平台4.4W用作Android虚拟设备。在ADV上设置Level 19和Platform 4.2.2，一切都按预期运行。

更改AVD目标

打开AVD Manager 工具 - ＆gt; Android-＆gt; AVD Manager。

Answer 2

通过Chk0nDanger更改上述值后然后我做了另一张海报发现的以下内容.. 这似乎解决了这个问题。

谢谢你们！

我有同样的问题。但是sdk版本不是造成这种例外的原因。

在AndroidManifest.xml文件中，主题中包含ActionBar。

android：theme =“@ style / AppTheme”＆gt;

将以上行更改为

android：theme =“@ android：style / Theme.DeviceDefault”＆gt;

这将修复异常。

运行默认的hello app Gradle和API
