android for 循环里面能更新数据库吗 android studio for循环

  临近毕业,目前大三后半学期,总想着该朝哪一个方向发展,由于本人是学习java语言的,所以在javaweb和Android之间犹豫不决,终于于今日决定疯狂学习Android。然后就从网上下载了Android Studio来安装,为什么选择了这个而不是eclipse呢,因为我觉得Android Studio作为Android最大的支持商google的亲儿子日后必火,虽然目前来看并不好。

  然而在安装过程中,出现了千奇百怪的问题。本人与大家一起分享,也为同我一样的新手出现同样的问题指南。

  首先Android Studio下载地址为:https://dl.google.com/dl/android/studio/install/1.0.0/android-studio-bundle-135.1629389.exe

  这样一路下载下来并没有出现什么大的问题,一路平平安安的就下载完了。但是下载完成之后出现了第一个问题。

  第一个问题:No JVM installation found。

  

  这是表明你没有安装64位虚拟机,我的计算机是64位的下载的Android Studio也是X64的所以提示我没有64位JVM。

  其实我之前是装有jdk的。但可能是我装的是32位jdk所以不能识别

  所以只能从甲骨文的官网重新下载了一个jdk这里提供甲骨文1.8_40的下载地址:http://download.oracle.com/otn-pub/java/jdk/8u40-b26/jdk-8u40-windows-x64.exe

  第二个问题:The following SDK components were not installed: build-tools-21.1.1, source-21, sys-img-x86-addon-google_apis-google-21, extra-android-m2repository, android-21, extra-google-m2repository, addon-google_apis-google-21, tools, platform-tools

  这是说没有办法安装sdk

  这个问题很蛋疼的问题,由于工信部对谷歌的封锁我们没办法访问sdk的更新地址所以就不能更新过去

  我从网上查到的方法是

——————————————————————————我是分割线————————————————————————

  

直接到解压目录(压缩包)中找到下面目录的文件,打开并在最后一行回车换行后加入 :

disable.android.first.run=true

然后保存。

其实我们上面只是延迟了它的加载  并没有阻挡SDK没有安装这个事实的延续,所以安装完成之后就会有这个东东

android for 循环里面能更新数据库吗 android studio for循环,android for 循环里面能更新数据库吗 android studio for循环_linux,第1张

点击进入之后就是我们又要面对的问题 ,怎么安装sdk在这之前先暂停

在百度上下载一个Android SDK进行安装

安装完成之后同样需要更新  

在此之前先去C:\Windows\System32\drivers\etc里面的hosts这个文件复制到其他地方用记事本打开然后在末尾加上

64.233.167.104 dl.google.com
64.233.167.104 dl-ssl.google.com

  这两行

替换原来的hosts(之所以先复制出来是因为需要管理员权限才能操作hosts这样复制回去的时候点继续就会自动请求管理员权限)

打开 安装目录下Android SDK Manager.exe

就更新完成了   

在上面的红色error中单击,系统会自动检测到SDK的位置由于已经更新完成一路next就安装完成了

--------------------------------------------------------------------------------------------------------------------------------------

假如依然不能完成,那么只能手动下载sdk了的各个组件了,这里提供下载地址使用迅雷下载等工具可以完成下载,因为迅雷这些下载工具不一定是从源地址下载的所以把文件一个个下载下来解压到对应目录,再指向这个目录即可.这种方式比较累,但是很有效,不会FQ的童鞋们就只能这样做了,这里提供各个组件的下载地址:
