This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the ‘java’ gradle plugin in a library submodule add
targetCompatibility = ‘1.7’
sourceCompatibility = ‘1.7’
to that submodule’s build.gradle file.

Never mind I have solved the issue. Thanks for the concern


#5

Hello,
could you give the solution that you used to solve your problem so that if other finds it in the same situation they will be able to repair.

thank you :wink:


#6

You are right… i will do that.


#7

@dotman any chance you can post what you did to fix this? I’ve tried multiple “fixes” from other forums but no luck.


#8

This is the fix to the issue open your build.gradle file and add the line below inside defaultConfig

defaultConfig {
multiDexEnabled true
}

And open project.properties file and check if you have the line below there

cordova.system.library.4=com.squareup.okhttp3:okhttp:3+

Then change it to this

cordova.system.library.4=com.squareup.okhttp3:okhttp:3.12.1

Save and run ionic cordova build android again. I hope it works for you
