为什么我的模拟器无法启动？我的第一个android应用

[英]Why won't my emulator launch? *my first android app*

原文 2014-07-01 12:56:14 6 1 android

I am writing my first android app. 我正在写我的第一个Android应用程序。 Literally, I haven't written a line of code yet. 从字面上看，我还没有编写任何代码。 I am following a simple tutorial for setting up my dev environment (made by google) and every time that I try to launch my app (one that is auto-generated and does nothing) it fails. 我正在遵循一个简单的教程来设置我的开发环境（由Google制造），并且每次尝试启动我的应用程序（自动生成且不执行任何操作）时，它都会失败。

When I try to 'run' the application directly from android studio without an emulator [API 17] open, I get no warning but nothing happens. 当我尝试在没有打开仿真器[API 17]的情况下直接从android studio“运行”应用程序时，我没有收到警告，但没有任何反应。

When I try to 'run' the application directly from android studio with an emulator [API 17] open, I get an error. 当我尝试“跑” 与模拟器[API 17]开于Android工作室直接申请，我得到一个错误。 The error states "Failure [INSTALL_FAILED_OLDER_SDK]" 错误状态为“ [INSTALL_FAILED_OLDER_SDK]失败”

To research this error, I tried to add lines to the build.gradle file that specifies the sdk version like so: defaultConfig { minSdkVersion 11 targetSdkVersion 19 } 为了研究此错误，我尝试向build.gradle文件中添加指定sdk版本的行，如下所示：defaultConfig {minSdkVersion 11 targetSdkVersion 19}

this results in the gradle file not being able to be built. 这导致无法构建gradle文件。

I verified that my project settings have a lower minsdkversion set then my current emulators version. 我确认我的项目设置的minsdkversion设置低于当前的模拟器版本。

I am not sure how to get this to actually run at this point. 我不确定如何在这一点上使其真正运行。 Realistically, environment setup should not be this difficult -- unless I am missing something. 实际上，环境设置应该不会那么困难-除非我缺少任何东西。

Any advice? 有什么建议吗？

Try opening your SDK manager and downloading all the APIs within your min-max android versions. 尝试打开您的SDK管理器并下载您的最小最大Android版本中的所有API。 You can try running your App for a single Api version to get started. 您可以尝试为单个Api版本运行您的应用程序以开始使用。
