Please help me @Hardik1705 im really stuck
Thank you
and
try this link i hope it’s time solve your problem…
I struggled with the same issue!
My solution was:
Setup your Environment Variables. (If you already setted up those ignore it).
ANDROID_HOME
ANDROID_SDK (same path as android_home)
Path (from java)
!REMOVE!
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
Next thing you want to check out is this link.
How you install it on windows:
Use Chocolatey
https://chocolatey.org/install
Just type this into your cmd
@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
It will automaticly download and install all files.
Next thing is now we want to install Gradle.
Type this into your cmd
choco install gradle
Test it out:
gradle -v
I gues that is all you have todo I hope I didn’t forgot anything please post your result!
Good luck
