+1 Same behavior

[nahidmbstu]

@udaisubramaniam did not work!

[blohamen]

Refer to my comment here for the fix: #25296 (comment)

Fixed for me

[rocky225]

because RN 0.60.0 suport androidx
and your module use RN 0.60.0
you can replace you build.gradle code '+' to '0.59.8' and
googlePlayServicesVersion = "15.0.1"
firebaseVersion = "17.6.0"
"react-native-camera": "^1.13.1"
See #25173 #25296

[nahidmbstu]

not clear what to do. @rocky225

[fellmann]

Add to your package level android/build.gradle in buildscript -> ext:

    googlePlayServicesVersion = "16.+"
    firebaseVersion = "17.6.0"

See:
#25173 (comment)
#25296 (comment)

[nahidmbstu]

@fellmann Tried that too . still the same error.

[yunhanxia]

Same issue

[DillionApple]

Same issue. All solutions listed above do not work for me.

[kstar11]

@fellmann thanks a lot!
this error troubled me...and add these code to android/build.gradle,block 'buildscript'
ext { googlePlayServicesVersion = "16.+" firebaseVersion = "17.6.0" }
it's works!

[poojasharma3106]

Same issue. All solutions listed above do not work for me.

[sebacaccaro]

Add to your package level android/build.gradle in buildscript -> ext:

    googlePlayServicesVersion = "16.+"
    firebaseVersion = "17.6.0"

thanks @fellmann
adding just googlePlayServicesVersion = "16.+" worked fine for me

[songoten28]

@nahidmbstu
Because not only 1 lib you are using relating to Google service.
you should try this " #25301 (comment) "
after you try above
If you found something cool like react-native-push-notification, react-native-device-info or something like that
add for that look like below

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

implementation (project(':react-native-push-notification'), {
        exclude group: "com.google.android.gms"
        exclude group: "com.google.firebase"
    })

don't forget

ext { googlePlayServicesVersion = "16.+" firebaseVersion = "17.6.0" }

This problem come from Google and burning out for 1 days

[LMarcinkowski]

@fellmann Solution works. Thanks! I just waste few hours of researching this bug :/

[flafuente]

@songoten28 thanks mate, you are a star.

[rakibhasan48]

I will suggest to strict type the following packages as recent google services updated caused a lot of conflicts in dependencies:

 implementation(project(':react-native-maps')) {
     exclude group: 'com.google.android.gms', module: 'play-services-base'
     exclude group: 'com.google.android.gms', module: 'play-services-maps'
 }
 implementation(project(":react-native-device-info"),  {
     exclude group: "com.google.android.gms"
 })
 implementation 'com.google.firebase:firebase-core:16.0.1'
 implementation 'com.google.firebase:firebase-messaging:17.0.0'
 implementation 'com.google.android.gms:play-services-base:16.0.0'
 implementation 'com.google.android.gms:play-services-maps:16.0.0'
 implementation 'com.google.android.gms:play-services-gcm:16.0.0'

Check if you are using any of these libraries and specify the versions instead of using '+'

The same issue, feeling that React native is broken. It all depends on how many packages you added to your project. The community does not maintain some packages. So it will break.

[felipepalazzo]

Refer to my comment here for the fix: #25296 (comment)

Fixed for me as well

[jackdvs]

For me, it was react-native-admob, had to change its google play ad service dependency version to

implementation 'com.google.android.gms:play-services-ads:16+'

@nahidmbstu

The same issue, feeling that React native is broken. It all depends on how many packages you added to your project. The community does not maintain some packages. So it will break.

your project's build.gradle
the modules has build.gradle file too
all build.gradle must replace

[ppv94]

i am getting same error
AAPT: No resource identifier found for attribute 'appCompon
entFactory' in package 'android'

i changed googlePlayServicesVersion = '+' to googlePlayServicesVersion = '16.+'

what should i do
this is my build.gradle
ext {
googlePlayServicesVersion = '16.+'
buildToolsVersion = "27.0.3"
minSdkVersion = 16
compileSdkVersion = 27
targetSdkVersion = 26
supportLibVersion = "27.1.0"
}

and my dependencies :

dependencies {
compile project(':react-native-image-crop-picker')
//compile project(':react-native-facebook-account-kit')
compile project(':react-native-youtube')
compile project(':react-native-vector-icons')
compile project(':react-native-compress-image')

compile 'com.google.android.gms:play-services-ads:16.0.0'
compile "com.facebook.react:react-native:+" // From node_modules
compile 'com.google.android.gms:play-services-auth:+' // should be at least 9.0.0
implementation (project(':react-native-facebook-account-kit')) {
exclude group: "com.android.support"
}
}

@nahidmbstu take a look at react-native-device-info/react-native-device-info#693 (comment). Using that, try to find which libraries from androidX is your project using and then add those libraries to the code below
configurations.all { resolutionStrategy.force ' ' } in android/build.gradle

[doancongbang1991]

modify your graddle.properties
android.enableJetifier=true
android.useAndroidX=true
use jetifier
npm install --save-dev jetifier (or use yarn, but install it locally in your project, not globally)
npx jetify or npx jetify -w=1 (to specify the number of parallel workers)
npx react-native run-android

[codedadysolutions]

There is a simple solution to fix this error (its worked for me)

Step 1:
Download Android Studio (Latest version, 3.4.1 or greater) & Open your android project in Android Studio.

Step 2:
Right Click on the app folder > Refactor > Migrate to AndroidX & click on migrate.

Step 3:
After migration, a Dialogue box appears, proceed with Do Refactor

It will give android X support for your project.

#25296 (comment)

it works for me!

[nysamnang]

I had the same issue and took me headache one day and a half.
Finally, I fixed this problem by just changing the version of Google Play Service.
See Release Notes of Google play service.

In android/app/build.gradle:

In my case i'm using play-services-base and play-services-maps.

Change all com.google.android.gms:play-services-* dependencies to version 16.+

    implementation 'com.google.android.gms:play-services-base:16.+'
    implementation 'com.google.android.gms:play-services-maps:16.+'

In android/build.gradle:

Add ext { googlePlayServicesVersion = "16.+" } to buildscript.

Re-Build project then everything works fine!!!

[jawsvk]

Ran into the same problem and fixed it by doing the following:

1. Go into gradle.properties file and add this to the code:

android.useAndroidX=true
android.enableJetifier=true

2. Run npm install --save-dev jetifier
3. Run npx jetify
4. Run npx react-native run-android to start your app

[canpoyrazoglu]

Adding
googlePlayServicesVersion = "16.+" and firebaseVersion = "17.6.0" to gradle's ext did NOT work for me.

I then tried @codedadysolutions's comment and migrated to AndroidX. It got rid of compile errors and got to compile, but in runtime I get:

This is a fresh new project with RN 0.60 RC2

[songoten28]

@canpoyrazoglu add your config like this
app build.gradle

defaultConfig {
        ndk {
          abiFilters "armeabi-v7a", "arm64-v8a", "x86", "x86_64"
        }
    }
    splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk false  // If true, also generate a universal APK
            include "armeabi-v7a", "x86", "arm64-v8a", "x86_64"
        }
    }
dependencies {
    implementation "org.webkit:android-jsc-intl:+"
}

This is a duplicate of #25293, please read the issue there to understand your problem. It's not strictly caused by the main react-native library itself.
