I had the same issue today.
After removing and adding the platform script tried to fetch that package again - successfully.

I tried removing and adding the platform again, but still having the same issue.

Yesterday my code works fine, but now I have the same Issue!
I have not updated anything. I don´t understand
ionic/cli-utils : 1.19.2
ionic (Ionic CLI) : 3.20.0
Android SDK Tools : 26.1.1

It looks like this is an issue with JCenters Bintray artefact mirror as the artefact is acutally available in Googles Repository:
https://maven.google.com/com/android/support/support-v4/26.1.0/support-v4-26.1.0.aar

Facing the same issue here for debug builds.
This started happening right after maven downloaded updates during a build for the com.android.support library.
Here is a snippet of the ionic cordova build android --verbose output:

i have'n reinstall gradle4.1.0-all but it doesn't work.

[aghaaliabbas]

i faced the same issue today, it was basically that gradle was not able to find this dependency.
So in order to resolve it i changed the following things in build.gradle files. There are two build.gradle files in ionic project.
change the order of repositories in both of them, take jcenter() to the bottom and add google() to the top and issue gets resolved, build successfully.

buildscript {
repositories {
mavenCentral()
maven {
url "https://maven.google.com"
}
jcenter()
}
}

allprojects {
repositories {
mavenCentral();
google();
jcenter()
}
}

@AghaAliAbbasKhan You sir, are a legend! How did you manage to determine this?

[sachinsemlety]

Actually I have tried repositories google() also, but it doesn't work work earlier, and now it is working properly without using google() repositories, @JacoRoos , can u try without using google() in gradle?

[aghaaliabbas]

@AghaAliAbbasKhan You sir, are a legend! How did you manage to determine this?

i figured that it dependencies are downloading from different centres based on these calls. As the dependency needed to be download was moved from jcenter so i decided to move maven above so that it uses maven for the downloading this dependency and if maven fails then use google. etc etc

[JacoRoos]

@sachinsemlety
I didn't copy his code, I simply moved my jcenter reference below my maven reference as he suggested. It seems that these repository references are specific to each project. This is what my files look like now (I didn't add or remove anything, just moved the refs around):

buildscript {
repositories {
maven {
url "https://maven.google.com"
}
jcenter()
}
}

allprojects {
repositories {
maven {
url "https://maven.google.com"
}
jcenter()
}
}

Moving the reference worked for me as well. Thanks guys.
