When I run

ionic cordova build android --prod

it shows errors below:

    ERROR: In <declare-styleable> FontFamilyFont, unable to find attribute android:fontVariationSettings
ERROR: In <declare-styleable> FontFamilyFont, unable to find attribute android:ttcIndex

    FAILED

    FAILURE: Build failed with an exception.

    * What went wrong:
    Execution failed for task ':processDebugResources'.
    > com.android.ide

.common.process.ProcessException: Failed to execute aapt

* Try:

Run with 
--stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

and in AndroidStudio, I clikc 'Build' button, it shows:

    Error:In <declare-styleable> FontFamilyFont, unable to find attribute android:fontVariationSettings
    Error:Execution failed for task ':processDebugResources'.
> com.android.ide.common.process.ProcessException: Failed to execute aapt

To solve that :

you_app_folder/plugin and look for plugin.xml in all the plugins

Go to your plugin folder, search in that directory for :

com.android.support:support-v4:+

OR

com.android.support:support-v4:24.1.1+

OR

com.android.support:appcompat-v7:28.0.0

Change it with :

com.android.support:support-v4:27.1.0

OR

com.android.support:appcompat-v7:27.1.1

then

Also, I executed 

ionic cordova platform remove android

and 

ionic cordova platform add android

    I had the same problem and changing from `com.android.support:support-v4:+` to compile `com.android.support:support-v4:23.+` fixed it for me. – Pavel Shorokhov Mar 19 '18 at 14:11
  • Thanks , works great – Amr.Ayoub Mar 21 '18 at 13:38

    I fixed it by editing `platforms/android/build.gradle` according to https://github.com/crosswalk-project/cordova-plugin-crosswalk-webview/issues/205#issuecomment-371669478 – Captain May 18 '18 at 11:31
  • Added this to `build-extras.gradle` configurations.all { resolutionStrategy { force 'com.android.support:support-v4:26+' } } Found info at - https://github.com/crosswalk-project/cordova-plugin-crosswalk-webview/issues/205#issuecomment-371669478 – nanusdad Jun 02 '18 at 10:12

    @nanusdad this is an option to change only the module you want to upgrade, not all of them – M0ns1f Jun 02 '18 at 12:55
