This is a solution to the above error that I want to document. I found other similar posts, but none described how this error can be associated with Cordova or Ionic.
If you are not careful, there can be a mismatch between the version of Gradle that Android Studio uses and the version of Gradle that Cordova / cordova-android specifies in its auto-generated application code. As you know, running
$ cordova platform add android
(or $ ionic platform add android
, if you are building an Ionic app) creates the native application code at the-project/platforms/android.
Inside that folder, the file: /the-project/platforms/android/cordova/lib/builders/GradleBuilder.js exports a variable as shown below:
var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-x.y-all.zip';
Where x and y depened on which version of Cordova / cordova-android are being used to build the native application code.
When you run
$ cordova build android
The version of Gradle specified in the distributionUrl
var is the version used for the build.
Now here comes the tricky part. When you import the project into Android Studio, you will most likely get a message strongly recommending that you upgrade Gradle to a newer version, as shown below:
If you do this, Android Studio will download a new version of Gradle and store it locally and configure the project to use the newly download local Gradle distribution, which is the radio option below the selected “Use default grade wrapper”, which I ended up deselecting because this will cause errors.
This will cause problems because Android Studio and Cordova will now be attempting to build the application with different versions of Gradle and you will get build errors within Android Studio and also with
$ cordova build android
in the command line. The solution with Cordova apps is to always keep the Android Studio project set to "Use default gradle wrapper" and ignore the tempting messages to upgrade. If you do want to use a newer version of Gradle, you can always change the distributionUrl var in the file mentioned above (however Cordova strongly discourages modifying code within the platforms folder since it is easily overwritten). At the time of writing this, I cannot tell is there is a way to set the Gradle version at the
$ cordova platform add android
step, which is when you would want to do it so you are never directly modifiying code inside of the-project/platforms
Another way to fix issue, that also works on Windows:
For me, the following commands solved the problem:
I want to extend @bungler answer.
I got confused with version of gradle & compatible version of android plugin for gradle. Following link has the list of compatibale versions mapping:
Gradle vs Android plugin for gradle - Compatible version list
For current version of gradle 3.3+, compatible version of android plugin is 2.3.3
So final settings will look like following:
STEP 1: Add following in env variables:
option a) update env variable:
or
option b ) you can download the gradle file and place it in
<project>/platforms/android/gradle/
and update env variable:STEP 2: Update following in
<project>/platforms/android/CordovaLib/build.gradle
This worked for me.
In follow up to Chuck Holbrooks answer, with following solution I get an error when trying to add android platform again saying it is already added.
My working Solution:
Switching back to "Use default gradle wrapper" didn't work for me on my ionic 1 project, but running
Worked for me
For follow error:
This command worked for me:
