Android studio 开发环境搭建

  一、环境:

  下载java jdk:http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html

下载Android Studio:http://developer.android.com/sdk/index.html

  二、安装步骤

    1、安装java jdk

        按照提示一步步来就行 ,如果需要配置环境变量参考 http://www.cnblogs.com/lmh2072005/p/5083648.html

    2、安装Android Studio和创建项目

    双击安装文件一步步安装即可。

  3、创建运行第一个Android apk hello world

  三、常见问题

  1、在运行app时提示未安装Intel HAXM错误信息:

    Emulator: ERROR: x86 emulation currently requires hardware acceleration!

     Please ensure Intel HAXM is properly installed and usable.

     CPU acceleration status: HAX kernel module is not installed!

解决方案:

    1) Open SDK Manager (In Android Studio, go to Tools > Android > SDK Manager) and Download Intel x86 Emulator Accelerator (HAXM installer) if you haven't.

    2) Now go to your SDK directory (C:\users\username\AppData\Local\Android\sdk, generally). In this directory Go to extras > intel > Hardware_Accelerated_Execution_Manager and run the file named "intelhaxm-android.exe".

In case you get an error like "Intel virtualization technology (vt,vt-x) is not enabled". Go to your BIOS settings and enable Hardware Virtualization.  //需要重启电脑设置bios

    3) Restart Android Studio and then try to start the AVD again.

      It might take a minute or 2 to show the emulator window.

  2、模拟器RAM过大,电脑内存不足,错误信息:

emulator: The memory needed by this VM exceeds the driver limit.

HAX is not working and emulator runs in emulation mode

在android studio 打开tools->android->avd manager  找到对应的avd 编辑, 在弹出的配置文件点击'Show Advanced Setting' ,

在详细设置里面把滚动条拉下来(滚动条很不明显,是个坑),根据自己电脑内存分配下内存

配置好后重启android studio

Run 'app' 一切ok

最后导出apk文件,在android studio -> build->Generate Signed APK 即可。
