Android开发相关笔记（win10）

 

android studio 不识别sdk目录的问题处理：

使用sdkmanager安装：

sdkmanager.bat "platform-tools" "platforms;android-29"

---

模拟器安装:

sdkmanager.bat "system-images;android-29;google_apis;x86_64"

---

flutter doctor 检查失败：

ANDROID已配置确报不完整：

sdkmanager.bat --list

看看有没有缺失，我本次win10的安装列表如下：

Installed packages:=====================] 100% Computing updates...

有些教程会缺少一些包比如build-tools;29.0.0所以建议额外注意一下。

license签署：

flutter doctor --android-licenses

emulator起不来报虚拟化相关的问题时可以尝试开windows的Hypervisor服务，配置入口略深：

windows设置最右边程序和功能

左侧启用或关闭windows功能

勾选Windows Hypervisor Platform

构建时卡在initializing gradle……

有可能时因为墙比较高，手动下载gradle吧（解压并将其bin目录追加入PATH环境变量）。

另外换国内的仓库吧。

flutter配置路径：<flutter_home>/packages/flutter_tools/gradle/flutter.gradle

    repositories {
        //google()
        //jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
    }
