I created a new ionic 5 app, & am trying to run it on my android device.
I installed this platform: ionic cordova platform add android:6.4, & then ran ionic cordova run android.
But I get this error message:
Also, here are my system variables:
Can someone please tell me what is causing this issue, & how can I resolve it?
Can you run this command and paste the entire output here?
ionic cordova platform add android --verbose
and
ionic cordova run android --verbose
Hi Matt,
Thanks for replying to this.
I’ve made some changes since posting, & am getting a different error now relating to gradle.
I created a basic android app & ran it in android studio just to make sure it compiles, & the app was displaying on my phone, so I’m not sure if that helps.
I ran your command. but can’t paste in the entire console, so I’ve added what I think is useful below:

I’ve found this issue on the Ionic Github, maybe it can help you sort out your problem.
→ Could not find an installed version of Gradle either in Android Studio, or on your system to install the gradle wrapper. Please include gradle in your path, or install Android Studio · Issue #11591 · ionic-team/ionic-framework · GitHub
It’s weird that it happens even when you’ve already installed Android Studio, but hey, it wouldn’t be fun if it didn’t work the first time 
1 . try jdk version 8 becaue this version is compatable
2. set java path without bin
