i am new in Ionic. I added android platform in my ionic application and tried to run the application in real android device but i am getting following error in my command prompt i am using windows 10 machine on my end.

```
Error: Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.
Looked here: C:\Users\CURRENT_USER\AppData\Local\Android\sdk\tools\templates\gradle\wrapper

```

following are my environment variables:

```
ANDROID_HOME=C:\Users\CURRENT_USER\AppData\Local\Android\sdk

JAVA_HOME=C:\Program Files (x86)\java\jdk1.8.0_121

```

Please suggest
