با سلام خدمت استاد مهدی و دیگر عزیزان
چه در web storm و چه در cmd من نمی توانم برنامه ام را اجرا کنم(ری اکت نیتیو) خطا در هر دو این است:FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ‘:app’.
> SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

* Try:
Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output. Run with –scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 5s
