Ionic3 Execution failed for task ':app:transformClassesWithDexBuilderForDebug' - push-notification

Question

I have been dealing with this for the past 2 weeks now.I'm building an application with Ionic3. Everything worked fine, Untill I install phonegap push plugin. Then I start to get this error
Execution failed for task ':app:transformClassesWithDexBuilderForDebug'. > com.android.build.api.transform.TransformException: java.lang.IllegalStateExce ption: Dex archives: setting .DEX extension only for .CLASS files
I have made research about this and none of the solution seemed to work for me. I have done below to app level build.gradle
defaultConfig {
multiDexEnabled true
}
i also added below code
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
Then I started gettin below error
Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
> java.io.IOException: Can't write
[C:\ionic\brinmiz\platforms\android\app\build

Answer 1

As explained here by the official documentation of Push Plugin, there is a known incompatibility between Push Plugin and another plugins that "are using an outdated way to declare dependencies such as android-support or play-services-gcm".
You can try to install cordova-android-support-gradle-release that will align various versions of the Android Support libraries specified by other plugins to a specific version.
cordova plugin add cordova-android-support-gradle-release --fetch
Also you can try to downgrade your cordova-android from 7.0.0 to 6.3.0 because there are also known issues with 7.x+. Delete your plugin folder(make sure you have all of them declared in config.xml) and run:
cordova platforms rm android
cordova platforms add android#6.3.0
If nothing do the job, update your answer with all the plugins used by your application using the next command and I will try to debug for you.
