Could Not Find Gradle Wrapper Within Android Sdk

Solution 1:

I think you need to update android sdk,

First you update your android sdk atleast API LEVEL 19 & tools & extra options as follow

& make sure to add sdk url in environment variable

Solution 2:

New Android Studio has moved gradle wrapper to C:\Program Files\Android\Android Studio\plugins\android\lib\templates\gradle\wrapper. I copied the templates\ folder to sdk\, then passed the compilation. However the command "Ionic emulate android" still failed with "Error: cmd: Command failed with exit code 1". I don't know how to go further :(
