Android : Unable to build app

EDIT by @kelset:

TL;DR:

• Google released a new Major version of their Google Play services and Firebase
• this new version has BREAKING CHANGES (release notes)
• some third-party libraries used in react-native projects have loose dependencies on said services, most likely in the :+ form in their gradle configuration
• this is causing Gradle buils to fail because of those BC mentioned above
• to fix, you need to set the dependency to a precise version instead of the :+
• you can find out which libraries are “pulling in” this new version by running gradlew app:dependencies and searching the output for androidx (more details here)

Please refer to this comment (and the follow ups) for more details on how to fix - in particular, for debugging, read this comment.

React Native version: 0.58.0 Platform : android

Here are android version: buildToolsVersion = “27.0.3” minSdkVersion = 19 compileSdkVersion = 26 targetSdkVersion = 26 supportLibVersion = “26.1.0”

Building app on android before today is working fine. and suddenly got this issue in android manifest file …\android\app\build\intermediates\manifests\full\debug\AndroidManifest.xml:46: AAPT: No resource identifier found for attribute ‘appComponentFactory’ in package ‘android’

hey @nodece thanks for the investigation, that seems to be the root cause!

It seems that google released a new version of their Play Services, and in particular com.google.android.gms:play-services-gcm - so if you are depending on latest (via something like com.google.android.gms:play-services-gcm:+) then you need to change it to instead rely on the previous version, in the example 16.0.0.

So you may have to do something like

implementation(project(":react-native-device-info"),  {
  exclude group: "com.google.android.gms"
})
implementation "com.google.android.gms:play-services-gcm:16.0.0"

I’m going to close this, as it seems to be caused by third-party libraries and not react native per-se - if something else pops up please comment ahead!

EDIT: if you are still experiencing the issue, it’s likely one of these two reasons:

1. you have other libraries (not device-info) that depend on latest, and you need to debug/find out which ones
2. you need to clean the gradle cache, you can use this: ./gradlew cleanBuildCache & ./gradlew clean from the /android folder

If it’s neither because of these, please provide a repro so that it can be investigated.

update: The root cause is related to androidx, google play service… try upgrade project to androidx

This problem seems to be triggered by the version of react-native-device-info? 2.1.2 constrain play services dependency to pre-AndroidX 16.1.0 react-native-device-info

yarn upgrade react-native-device-info@2.1.2
cd android && gradlew clean
react-native run-android

It working for me.
