Ionic Cordova Android build fetches cordova-android 9 instead of 10

I have updated my Ionic Cordova project on my development machine to use cordova-android 10, via:
ionic cordova platform rm android
ionic cordova platform add android#latest
After this I have the following in my package.json:
"cordova-android": "^10.1.1",
I've updated build tools and sdk etc in Android Studio, do my build and all works fine.
Now, I check in my source, and do the same Android Studio updates on my Mac.
However, now when I do the same build (on the Mac), I see the message:
> cordova platform add android --save
Using cordova-fetch for cordova-android#^9.0.0
And also it has updated my package.json back to "cordova-android": "9.1.0".
My question is, why could it do this, instead of fetching the 10.1.1 as is dictated in my package.json?

I found a solution.
First, check the version of your android platform by using this command
cordova platform
You should see the version 9.x.x
Then run the following command
cordova platform add android#10.1.1
Re execute
cordova platform
You will see the version 10.1.1
That's it

getting net::ERR_CONNECTION_REFUSED (http://localhost:8080) on android 4.4.2 version

I build a simple ionic project from this tutorial.
It runs on Xiaomi Mix 2 phone (android version 8.0.0) and on browser without any problem.
But when I deployed to the samsung note 2 (android version 4.4.2),
it gives an application error with this message:
net::ERR_CONNECTION_REFUSED (http://localhost:8080)
Why am I getting this error?
Any advice and suggestions will be appreciated.
Kemal.

I faced the same problem in Android 4.4, Android 6.0 but not in Android 8.0. I just added this code in config.xml to allow the localhost.
<allow-navigation href="http://localhost:8080/*"/>

WKWebView

Your problem is caused by the cordova-plugin-ionic-webview plugin that is part of every new or updated Ionic app.
This used to apply only to iOS, where it replaced the UIWebView with WKWebView, but on July 23rd 2018 they released version 2.0 of the plugin, that also included changes to the webview used on Android.
The Android webview now uses a local webserver at localhost:8080 to show your app instead of requesting the files directly from the file system.
Unfortunately this change also included this bit in the documentation:
Requirements
- […]
- Android: Android 5.0+ and cordova-android 6.4+
So cordova-plugin-ionic-webview just doesn’t support Android earlier than 5.0 any more, which of course means your app will not work on Android 4.x.
One solution is to downgrade the plugin to the last version that supported Android 4.x:
ionic cordova plugin add cordova-plugin-ionic-webview#1.2.1
More elaborate information and alternative solutions:
https://ionic.zone/debug/ionic-and-android-4

In case anyone is still not able to resolve this error,
Find the compatible webview version which works for you and run the below commands:
cordova plugin rm cordova-plugin-ionic-webview
cordova plugin add cordova-plugin-ionic-webview#4.1.3
In case you're using ionic, install the ionic plugin wrapper. (Skip this if your project is not an ionic project)
npm install #ionic-native/ionic-webview
Finally do clean installation of the platform and plugins. Delete
the plugins folder and run the following commands:
cordova platforms remove android
ionic cordova build android
Or, if you use ionic,
ionic cordova platforms remove android
ionic cordova build android
Additional information: Plugin version cordova-plugin-ionic-webview#4.1.3 worked for me for the below cordova and android versions:
Cordova CLI : 9.0.0 (cordova-lib#9.0.1)
Cordova Platforms : android 8.1.0
Android target : android-28
Android SDK Tools : 26.1.1
cordova-android : 8.1.0

You are getting the error because every function and module in Android only works from a certain version on newer. It could be 4.4.3 and up, 5.0 and up, or even 8.0 and up. It just depends. This means if and when you deploy it you will be required to select a minimum version. There is nothing you can do to fix it other than trying on a newer version. You can also change the code completely to work with older modules.

I've had same error even on new devices. After that, I've reinstalled cordova-plugin-ionic-webview plugin. Reinstallation upgraded plugin from 4.0.0 to 5.0.0 and added new line to config.xml:
<allow-navigation href="http://localhost:8100" sessionid="f8f1cc34" />
I'm still waiting for review, but hope this will help.

I had this problem for days and all the solutions I found did not work.
Ionic recommends using Capacitor to build the app and not Cordova. With Cordova does not work, on the other hand with Capacitor it works fine.
In your app directory first delete the Android folder (if any) and the one in Platform / Android folder.
I used these commands in this order launched by Powershell while staying in the APP directory
ionic build
ionic capacitor add android
npx cap open android
The first command will create a www folder.
If the last command give an error and does not open Android Studio, do it manually, (I recommend using 4.0 version). Open Android Studio → open folder, navigate to the folder named Android located in the folder in your APP and then it worked for me. In Android Sudio 4 make sure you have Gradle updated and the SDK loaded.

/android/CordovaLib/src/org/apache/cordova/engine/SystemWebViewClient.java
onReceivedError(WebView view, WebResourceRequest request,
WebResourceError error) {
super.onReceivedError(view, request, error);
if (error.getErrorCode() == WebViewClient.ERROR_CONNECT) { //net::ERR_CONNECTION_REFUSED
view.goForward();
return;
} else {
errorMessage();
}
}

"Error: Your android platform does not have Api.js" when trying to build android version 5.x.x

cordova version is 7.0.1
node version is v8.0.0
when running cordova platform add android#5 everything works fine. (except for cordova-plugin-media requiring android version >=6.1.0 but thats another story)
When running cordova platform add android#4 (similar for cordova platform add android#3) I get
Using cordova-fetch for cordova-android#4
Adding android project...
Error: Your android platform does not have Api.js
despite cordova officially still supporting those android versions. What am I missing here?
The only other post remotely containing this particular error I found is here, but it was not helpful.

I solved this problem trying 6.0.0 version
npm install -g cordova#6.0.0
then there was error with bplist-parser in npm
npm install -g bplist-parser
All works fine!

Cordova Error using Cordova-Android 6.2.0 - getFileResources is not a function

I have an ionic/cordova project using:
cordova-android#6.2.0
cordova-plugin-crosswalk-webview#2.3.0
cordova cli 6.4.0
ionic 1.3.3
When I try to add the Android platform, I get the following output
================
$ ionic platform add android#6.2.0
Adding android project...
Creating Cordova project for the Android platform:
Path: platforms/android
Package: com.ionicframework.name
Name: name
Activity: MainActivity
Android target: android-25
Subproject Path: CordovaLib
Android project created with cordova-android#6.2.0
Error: cordovaProject.projectConfig.getFileResources is not a function

It seems this issue is related to a bug in cordova-android#6.2.0, as confirmed here: https://issues.apache.org/jira/browse/CB-12633
I have now updated my system to cordova-cli - cordova#6.5.0 and cordova-android#6.2.1, and it seemed to work.
Update to version 6 of cordova cli with:
npm install -g cordova#6
And then add the correct version of cordova-android
cordova platform add android#6
Not directly related to this issue, but once I got it working, my system did complain about the gradle path not being set when I tried building my app, and so I followed the steps here: https://gradle.org/install#with-homebrew, and now all builds successfully.

update cordova
npm install -g cordova
and then try to add platform or if any problem with new version of cordova then use below
There is a problem with cordova version 6.4.0 and android 6.2.1. So, please try with below compatible versions
cordova version must be 6.4.0
npm install -g cordova#6.4.0
Install android in your project
cordova platform add android#6.1.2
or
ionic platform add android#6.1.2

Do whatever #IonicBurger has said above.
Also make sure that for Cordova based projects, each cordova version has specific dependency on android SDK and android build tools installed.
I am currently using Ionic 3 and I faced the same issue.
Make sure cordova is latest: npm i cordova -g will do the job. Note what version of cordova is installed by checking cordova -v. After that ensure you have installed ionic-native; this usually comes with ionic installation, but it wont harm to installed this again locally with npm i ionic-native --save
See all available platforms: ionic cordova platform list. Some plugins like camera, media etc have very specific cordova requirements (refer here)
When you install a plugin, you may encounter such error sometimes: 'Plugin doesn't support this project's cordova-android version. cordova-android: 6.1.2, failed version requirement: >=6.3.0
Skipping 'cordova-plugin-camera' for android'. Thats okay. This can be resolved by above two steps. Most importantly remember this: Ensure you have latest Android Build Tools and SDK installed.
Please see the following image for more detail:
Note that this answer works best with Windows environment.

Updating to cordova#6.5.0 didn't work - I got error that this version is not found
Instead reverting to cordova#6.1.2 did work
cordova platform update android#6.1.2 --save

It is not the right solution downgrade the cordova version. If you want to use the lastest version of cordova and ionic, instead of using
ionic cordova platform add android
Just do:
cordova platform add android
works like a charm!
Good coding!

This problem occured for me when switching between two ionic projects.
I fixed it by trying another node version and it works.
I used nvm use x.x.x and by downgrading to a previous nodejs version, I was able to build my project.
Hope it'll help someone.

Downgrade Phonegap android version from 3.40 to 2.9.0

I am using phonegap 3.4.0 version for my android app project. My app is working fine in this version. Now, I want to test my app in cordova version 2.9.0. I have searched net and haven't get a grip on this issue.
My question is, how do i downgrade my phonegap version 3.4.0 to phonegap version 2.9.0?
also, cordova library is not showing up in my eclipse after changing version to 2.9.0. Without CordovaLib the project will not run. What should do to add CordovaLib in my app?

To downgrade my phonegap version 3.4.0 to phonegap version 2.9.0, I used the below command line interface:
$ sudo npm install -g cordova#2.9.0
This Link helps me to add CordovaLib in both ios and android.
REF: Phonegap 3.3 Eclipse: -CordovaLib project missing Android properties

npm install -g phonegap#2.9.0-rc1-0.12.2
