So it doesn’t re-install automatically. Well, we tried. Now you have to install manually again. 
No problem, it is always worth trying .
Ok, feedback on the Ionic CLI issue:
Yep, definitely Cordova/Android issue. I would mess with the installed SDK, Cordova versions, and Cordova Android platform versions, preferring the latest versions. That generally clears up weird build errors for me.
So - play with gradle a bit. Something is strange there. Also look into cordova-android, maybe the Cordova people know more.
I talked to the Cordova guys about this:
my hypothesis is you are using a version of cordova-android that is older than 6.1, and android sdk tools that are v26 or newer
So here is how we get these:
- Android Tools version:
android --version
If it tells you it’s deprecated, you’re running the latest version (>= v26.x.x)
If it tells you the android command doesn’t exist, you’re one version behind (~ v25.2.3)
If it prints out a version number, you’re 2 or more versions behind (<= v25.2.2)
If you are >=26 then run sdkmanager --list in your Android SDK directory, subdirectory /tools/bin. At the end of the output you should something like this:
Available Updates:
ID | Installed | Available
------- | ------- | -------
emulator | 26.0.0 | 26.0.3
extras;google;m2repository | 46 | 47
tools | 26.0.1 | 26.0.2
- And for the cordova-android version just run
cordova platform list.
Please run these two commands and report back what you get. Thanks.

android --version:
*************************************************************************
The "android" command is deprecated.
For manual SDK, AVD, and project management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
*************************************************************************
Invalid or unsupported command "--version"
Supported commands are:
android list target
android list avd
android list device
android create avd
android move avd
android delete avd

Damn - this means you are on all the newest (and required) versions and it is still failing for you.
I think you should create an issue with Cordova about that here: https://issues.apache.org/jira/browse/CB/?selectedTab=com.atlassian.jira.jira-projects-plugin:issues-panel Include all the information I asked from you over this thread, the last few are most important for them.
Ok, one last try and idea: Run cordova requirements again if it recognizes everything right now.
Thank you for your perseverance 
, cordova requirements outputs:
Requirements check results for android:
Java JDK: installed 1.8.0
Android SDK: installed true
Android target: installed android-25
Gradle: installed /usr/share/gradle/bin/gradle
And unfortunately the error too is persevering… 
Then off you go, create an issue over there
I fixed this issue by upgrading Gradle to version 3.5, solution given by Fabio Fabbri, here.

Hm, what version did you have before?
It was the 1.4 one, it seems that it is the officially distributed for Ubuntu 14.04.

Oh ok. So cordova requirements only checks if Gradle is installed, but not if it’s a new enough version.
Hii my problem is solved actually ut was not a big issue just in android studio gradle was missing and then I downloaded gradle and gave path to android studio and it works fine

Run cordova requirements. All successful?
If yes, remove and then re-add the android platform.
Hi,
This is my cordova requirements output

Still no luck.
