手贱删了些sdk以腾电脑空间。结果ionic打包Android出错。
0,SDK Manager AVD Manager都打不开了啊,啊，啊，啊，啊。。。
这个也是需要下载Android SDK Manager，与下面相同。
1，Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.

I just experienced the same problem.
It may be an occlusion in the instructions regarding how to install (or upgrade) Android Studio with all the SDK Tools which both you and I missed or possibly a bug created by a new release of Studio which does not follow the same file conventions as the older versions. I lean towards the latter since many of the SO posts on this topic seems to point to an ANDROID_PATH with a folder called android-sdk which does not appear in the latest (2.3.0.8) version.
There appears to be a workaround though, which I just got to work on my machine. Here's what I did:
- Download tools_r25.2.3-windows.zip from Android Downloads.
- Extracted zip on desktop
- Replaced C:UsersusernameAppDataLocalAndroidsdk ools with extracted sub-folder tools/
In project folder:
$ cordova platforms remove android
$ cordova platforms add android
重新下载Android SDK tools 去官网，覆盖到Android目录下（C:Program Files (x86)Androidandroid-sdk）即可。
2，类似下面标题的一个错误，也是安装了GoogleApis好了。
failed to find target with hash string android-23In my case, clearing caché didn't work.
On SDK Manager, be sure to check the box on "show package descriptions"; then you should also select the "Google APIs" for the version you are willing to install.
Install it and then you should be ok
ionic build android --prod --release出现如下错误：

原因是手贱腾电脑空间删了些以为“没用”的sdk，谁知把“Android Support Repository”删了，打开SDK Manager 重新install就行了。
