I have been searching for a solution, tried manually adding gradle to following path by running gradle wrapper command:
C:\Users\g\AppData\Local\Android\sdk\tools\gradle
Also tried the instructions given at this link
Updated all sdk tools using sdk manager inside the android studio.
I have android studio installed(also able to build andriod native apps using it) and path to sdk tools and ANDRIOD_HOME configured inside the system environment variables.
Please help me figure out how to run the ionic apps on Android.
