Answer 1

I was facing this issue. The problem was that my ANDROID_HOME path was pointing to Android Studio's folder. I changed it to point to my Android SDK Folder and problem was solved.

1. Check your ANDROID_HOME:

echo $ANDROID_HOME

2. It should point to the Android SDK Folder:

export ANDROID_HOME="your-android-sdk-folder"

Answer 2

I figured it out, the problem was due to a misconfigured config.xml entry:

<widget xmlns="http://www.w3.org/ns/widgets"
        xmlns:cdv="http://cordova.apache.org/ns/1.0"
        id="ch.papers.test"
        version="1.0.{BUILD_NUMBER}"
        android-versionCode="{BUILD_NUMBER}">...

Which we use for our Jenkins configuration. Unfortunately the error message was quite confusing.

Update corrected version:

<widget xmlns="http://www.w3.org/ns/widgets"
        xmlns:cdv="http://cordova.apache.org/ns/1.0"
        id="ch.papers.test"
        version="1.0.0"
        android-versionCode="1">...

I had the same issue. I fixed it as follows:-

Open Android studio configuration.

Go to config>SDK Manager>Android SDK>SDK Tools and install Android SDK Build-Tools.

Check the ANDROID_HOME variable. I am on mac, so it points to "/Users/user_name/Library/Android/sdk/"

If not set correctly set it as follows:-

export ANDROID_HOME="/Users/user_name/Library/Android/sdk/"

Now build it again and it should work fine.

PS:Getting android sdk by installing Android Studio is highly recommended than installing the sdk manually. This way you will not run into unnecessary trouble.

I solved this issue by saving the build.gradle and/or the build-extras.gradle with Unix (LF) line endings.. Your android-versionCode should have nothing to do with the buildversion of your android sdk...
