Execution failed for task \':app:processDebugResources\'.
This error comes when execute \"ionic cordova build android\". Searched for a long time but no luck. Anyone can
Actually this is a android support problem. so first find out which android support library installed in your android sdk.
in my sdk com.android.support:support-v4:24.1.1+ so i replaced the code in project.properites file
cordova.system.library.1=com.android.support:support-v4:24.1.1+
in the project folder try:
cordova clean
ionic cordova build <platform_name>
I know it's a very late answer, incase someone still facing this issues in 2019.
It's caused due to gradle, add this gradle support plugin and it should be fine:
cordova plugin add cordova-android-support-gradle-release
