[ERROR] An error occurred while running cordova build android (exit code 1).

1.Remove platforms (you can delete it from folder)
2.Remove node_modules (you can delete it from folder)
3.Upgrade your ionic-cli version to the latest (npm update -g ionic )
4.run npm install
5.run ionic cordova platform add android
6.run ionic cordova run android
Try these steps accordingly and it will work. If not try updating android api and sdk tools and re-do the steps.

Gradle error while trying to build android application using Cordova

I use cordova to build android apps:
$ cordova build android
I got an error:
Error: 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
Then I tried install gradle:
$ sudo apt install gradle
And then I'm struggling with this one:
aqil#dell:~/hello$ cordova build
ANDROID_HOME=/home/aqil/Android/Sdk
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
/usr/lib/jvm/java-8-openjdk-amd64/bin/java: symbol lookup error: /usr/lib/jni/libnative-platform-curses.so: undefined symbol: tgetent
Error: /usr/share/gradle/bin/gradle: Command failed with exit code 127

This worked for me:
Remove Gradle sudo apt-get remove gradle
Add this to your .bashrc file: export PATH=${PATH}:/opt/android-studio/gradle/gradle-X.XX.X/bin (Where X.XX.X is the version under this path.)
Now cordova build android should work without errors.

I finally could solve the issue. It was something wrong with the gradle. First step: removing it.
$ sudo apt remove gradle
Then i downloaded it manually from the link below
gradle-3.5.zip
Extract then add it's path into the environment using the command below:
$ sudo gedit ~/.bashrc
Add these two path at the bottom of the file:
export GRADLE_HOME=/home/aqil/Android/gradle-3.5
export PATH=$PATH:$GRADLE_HOME/bin
Final step, Tried building but encountered an error:

Ubuntu 16/Cordova 6.4/Android: Could not resolve com.android.tools.build:gradle

I'm trying to use Cordova 6.4 with Android Studio in Ubuntu 16 OS.
I've installed the Android Studio Correctly and downloads the SDK.
And the npm and cordova is also installed.
And I tried to create a project:
cordova create myapp
cd myapp
cordova platform add android
And this yields the following error:

And if I run cordova run android after that, it still tells the block of Could not resolve com.android.tools.build:gradle:2.2.0. error.
The same thing seemed not happening under windows.
I've search around the web with no luck. Anyone knows how?

The below article tells how to import a ssl certificate of a secific site to java environment.
https://github.com/meteor/meteor/issues/6362#issuecomment-262684912
Step 1 : Download the certificate
Download this file.
Or the same on Mozilla Firefox :
Go to https://repo1.maven.org
Click on the green padlock at the left of adress bar.
Click on Details.
Click on View certificate.
Click on Details.
Click on Export.
Export file to "X.509 Certificate (PEM) (*.crt; *.pem)"
Step 2 : Add the certificate to default java keystore
sudo keytool -import -alias MavenRepo -keystore $JAVA_HOME/jre/lib/security/cacerts -file /PATH/TO/YOUR/EXPORTED/FILE.crt
Your $JAVA_HOME variable is normally declared in your .bashrc file, so you can use this command just replacing the /PATH/TO/YOUR/EXPORTED/FILE parameter.
PS : The default password of java keystore is : changeit
It get the procedure a bit forward, but still not solved.
Finally I solved the problem by reinstall the OS.
It seemed it is not relavent with ubuntu or linux itself, codova and android studio worked well in ubuntu after I reinstall the OS.

How to build phonegap offline from command line

I'm using phonegap 100% from the command line. If I build while connected to the internet it works
$ phonegap build android
[phonegap] executing 'cordova build android'...
[phonegap] completed 'cordova build android'
But if I disconnect from the internet I get errors

Why is the command line version phoning home? How do I get this to build 100% offline?
Note: I see this error as the 2nd line when trying to build offline
cp: no such file or directory: /Users/gregg/src/hft-mobile-app/icon.png
But as you can see that error does not occur online. Plus supposedly whatever that issue was was fixed according to this
I'm on OSX, I've got the Android SDK installed. I had no idea it was calling home. How do I get it to build offline?

This is what I have experienced till now. Ionic uses gradle for android build. It first time downloads all the dependencies from internet. So internet is most for first gradle build but it caches them and no internet is needed for further build.Since you are having problem why don't you globally update your cordova and ionic.
npm install -g cordova ionic
