error: resource android:attr/fontVariationSettings not found

由 强颜欢笑 提交于 2019-11-26 19:40:29

try to change the compileSdkVersion to:

compileSdkVersion 28

fontVariationSettings added in api level 28. Api doc here

This is caused by an incompatibility with the android support library that changed to version 28. I solved the problem by forcing the build to use a lower support library. //like build gradle

configurations.all {
        resolutionStrategy {
                force 'com.android.support:support-v4:27.1.0'
    }
}

My project built successfully immediately after I changed this. Hope this might help you too. I lost a day of development because of this!.

For those that must keep compileSdkVersion 27 and are unable to upgrade to androidx yet, you must not upgrade to (or over) the versions of dependencies in the following links. These links are where the breaking change was introduced. You must find an earlier version that doesn't use androidx.

https://firebase.google.com/support/release-notes/android#update_-_june_17_2019

https://developers.google.com/android/guides/releases#june_17_2019

For instance, the following are compatible with compileSdkVersion 27:

dependencies {
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.google.android.gms:play-services-maps:16.1.0'
    implementation 'com.google.android.gms:play-services-location:16.0.0'
    implementation 'com.google.firebase:firebase-core:16.0.9'
    implementation 'com.google.firebase:firebase-messaging:18.0.0'
}

The following will break with compileSdkVersion 27 and are only compatible with compileSdkVersion 28:

dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.google.android.gms:play-services-maps:17.0.0'
    implementation 'com.google.android.gms:play-services-location:17.0.0'
    implementation 'com.google.firebase:firebase-core:17.0.0'
    implementation 'com.google.firebase:firebase-messaging:19.0.0'
}

If you are updating to v28

change the compileSdkVersion to compileSdkVersion 28

For native Android apps (not Cordova) solution for me is:

Was: 

implementation 'com.android.support:support-v13:+'

Now:

implementation 'com.android.support:support-v13:27.1.1'

Another fix for Ionic 3 devs is to create build-extras.gradle inside platforms/android and put following

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-v4:27.1.0'
    }
}

Note that build-extras.gradle is not the same as build.gradle

I solve this problem with the line below:

cordova plugin add cordova-android-support-gradle-release --save

After that the compile was succesful.

@All the issue is because of the latest major breaking changes in the google play service and firebase June 17, 2019 release.

If you are on Ionic or Cordova project. Please go through all the plugins where it has dependency google play service and firebase service with + mark

Example:

In my firebase cordova integration I had com.google.firebase:firebase-core:+ com.google.firebase:firebase-messaging:+ So the plus always downloading the latest release which was causing error. Change + with version number as per the March 15, 2019 release https://developers.google.com/android/guides/releases

Make sure to replace + symbols with actual version in build.gradle file of cordova library

Usually it's because of sdk versions and/or dependencies.

For Cordova developers, put your dependencies settings in "project.properties" file under CORDOVA_PROJECT_ROOT/platforms/android/ folder, like this:

target=android-26
android.library.reference.1=CordovaLib
android.library.reference.2=app
cordova.system.library.1=com.android.support:support-v4:26.1.0
cordova.gradle.include.2=cordova-plugin-googlemaps/app-tbxml-android.gradle
cordova.system.library.3=com.android.support:support-core-utils:26.1.0
cordova.system.library.4=com.google.android.gms:play-services-maps:15.0.0
cordova.system.library.5=com.google.android.gms:play-services-location:15.0.0

So if you use CLI "cordova build", it will overwrite the dependencies section:

dependencies {
    implementation fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START 
   /* section being overwritten by cordova, referencing project.properties */
...
    // SUB-PROJECT DEPENDENCIES END
}

If you are using proper libraries and its versions in project.properties, you should be fine.

If anybody has this error using phonegap or cordova with the cordova-plugin-fcm-ng or cordova-plugin-fcm plugin, the solution that worked for me is creating the extra config file for gradle "build-extras.gradle" in the \platforms\android\app folder, and putting the following lines in it

configurations.all {
 resolutionStrategy {
  force 'com.google.firebase:firebase-messaging:18.0.0'
  force 'com.google.firebase:firebase-core:16.0.8'
 }
}

I found this solution reading this page https://github.com/facebook/react-native/issues/25371, in particular comment of shreyakupadhyay on 30/07/19 and consulting https://developers.google.com/android/guides/releases#may_07_2019 about last libraries version.

For Ionic 3 devs. I had to update the platforms/android/project.properties file ONLY on:

cordova.system.library.2

to be v4:28.0.0+ otherwise the build kept failing.

After doing so, my project.properties file contents are shown below:

target=android-26
android.library.reference.1=CordovaLib
cordova.system.library.1=com.android.support:support-v4:24.1.1+
cordova.system.library.2=com.android.support:support-v4:28.0.0+
cordova.system.library.3=com.android.support:support-v4:+
cordova.system.library.4=com.android.support:support-v4:25.+
cordova.system.library.5=com.android.support:appcompat-v7:25.+
cordova.gradle.include.1=cordova-plugin-googlemaps/starter-tbxml-android.gradle
cordova.system.library.6=com.google.android.gms:play-services-maps:15.0.1
cordova.system.library.7=com.google.android.gms:play-services-location:15.0.1
cordova.system.library.8=com.android.support:support-core-utils:26.1.0
cordova.system.library.9=com.squareup.okhttp3:okhttp-urlconnection:3.10.0
cordova.gradle.include.2=cordova-android-support-gradle-release/pasma-cordova-android-support-gradle-release.gradle

I hope this helps someone. Was a real problem for me.

This was a pain in the ass for me! Especially after updating to Android Studio 3.2.1 and Gradle 4.6 (for Gradle developers).

I think there is more than one factor that could cause such a build exception. For me, I had the following lines of code in my gradle.properties file (using SDK version 27):

android.useAndroidX=true
android.enableJetifier=true

AndroidX is the alternative to Android's default Support Library and should be used when compiling and targeting SDK version 28 (API 28). Before the updating Android Studio and Gradle, I had added the lines above in preparation to eventually fully migrate to AndroidX to use SDK version 28 and the build ran successfully. It was only after the update that I received an error similar to that above:

error: resource android:attr/fontVariationSettings not found

Hope this helps.

For me : My external library was using this attributes attr/fontVariationSettings and attr/ttcIndex so I downgrade my library version and sync project . everything fine

So now :

 compileSdkVersion 27 
 implementation 'com.android.support:appcompat-v7:27.1.1'

and for future readers that library was google's easypermission.

implementation 'pub.devrel:easypermissions:2.0.0'

This lib is using sdkversion 28, I have to downgrade to 1.3.0

If you have stumbled upon this problem due to getting this error recently out of nowhere in react native- this is due to the latest BREAKING CHANGE in Google Play service and Firebase. Check this thread first -

https://github.com/facebook/react-native/issues/25293

And solution would mostly be like this -

https://github.com/facebook/react-native/issues/25293#issuecomment-503045776

I had the same error, but don't know why it appeared. After searching solution I migrated project to AndroidX (Refactor -> Migrate to AndroidX...) and then manually changed whole classes imports etc. and in layout files too (RecyclerViews, ConstraintLayouts, Toolbars etc.). I changed also compileSdkVersion and targetSdkVersion to 28 version and whole project/application works fine.
