I solved this issue by changing the version of below libraries to '16.1.0', in build.gradle file of react-native-push-notification.

com.google.android.gms:play-services-gcm --> '16.1.0' // default +

com.google.firebase:firebase-messaging --> '15.0.2' . // default +

thanks @engylemure for his easy solution.

My react-native-push-notification build.gradle file now looks like

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

apply plugin: 'com.android.library'
def DEFAULT_GOOGLE_PLAY_SERVICES_VERSION    = "16.0.1"

def safeExtGet(prop, fallback) {
    rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
}

android {
    compileSdkVersion safeExtGet('compileSdkVersion', 28)
    buildToolsVersion safeExtGet('buildToolsVersion', '28.0.3')

    defaultConfig {
        minSdkVersion safeExtGet('minSdkVersion', 16)
        targetSdkVersion safeExtGet('targetSdkVersion', 28)
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    def googlePlayServicesVersion = rootProject.hasProperty('googlePlayServicesVersion')  ? rootProject.googlePlayServicesVersion : DEFAULT_GOOGLE_PLAY_SERVICES_VERSION

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    testImplementation 'junit:junit:4.12'
    implementation "com.android.support:appcompat-v7:${safeExtGet('supportLibVersion', '28.0.0')}"
    implementation "com.facebook.react:react-native:${safeExtGet('reactNativeVersion', '+')}"
    implementation "com.google.android.gms:play-services-gcm:$googlePlayServicesVersion"
    implementation 'me.leolin:ShortcutBadger:1.1.8@aar'
    implementation "com.google.firebase:firebase-messaging:$googlePlayServicesVersion"
}

This issue is caused by breaking changes in latest version of google libraries where androidx and support libraries cannot coexist.

Hope it will work :)

[Webbgrey]

Still doesn't work any other ideas?

[faisal3413]

@Webbgrey try this link to understand and solve the issue

https://www.jianshu.com/p/f7a7a8765294

[Webbgrey]

@faisal3413 Still doesn't work. I tried all versions but seems like there is no hope.

[faisal3413]

@Webbgrey run below command

cd android && ./gradlew :app:dependencies

and saerch and find for 'androidx' to know which modules have been using androidx, then downgrade google libraries versions like

com.google.android.gms:play-services-gcm

com.google.firebase:firebase-messaging

[saadmutahar]

@faisal3413 thanks, it worked for me. :)

I just getting this

[faisal3413]

@Webbgrey this is other issue, try to add

implementation 'com.google.firebase:firebase-messaging:15.0.2'

in dependencies of android/app/build.gradle file and try to sync with android studio.

[Webbgrey]

@faisal3413 Oh my god what a problematic module

For solving this issue i would recommend to define explicitly the version for the ext variables
at the android/build.gradle at your root project

ext {
    googlePlayServicesVersion = "16.1.0" // default: "+"
    firebaseVersion = "15.0.2" // default: "+"

    // Other settings
    compileSdkVersion = <Your compile SDK version> // default: 23
    buildToolsVersion = "<Your build tools version>" // default: "23.0.1"
    targetSdkVersion = <Your target SDK version> // default: 23
    supportLibVersion = "<Your support lib version>" // default: 23.1.1
}

[bhlshrf]

try this:
add these two lines into the file './android/gradle.properties':

android.useAndroidX=true
android.enableJetifier=true

and then:

npm install --save-dev jetifier
npx jetify
npx react-native run-android

edit: typo (npx jetifier to npx jetify)

[LeanidHreska]

@bhlshrf That's working for me, thank you.

[maulidiyah-nur]

thank you @engylemure you save my life

[capJavert]

Published forked version with hardcoded (pre androidx) packages:
@capjavert/react-native-push-notification

Solved it like this because some other packages also depend on ext param googlePlayServicesVersion and I couldn't match versions to satisfy my build.

[DanielVenturini]

@capJavert @faisal3413 it works for me.

But, i don't change the com.facebook.react:react-native.

Thanks

[kalraneeraj24550]

thanks @engylemure sir, your solution worked for me

[Mouzmi]

@faisal3413 Your solution works perfectly, Thank you :)

[Dror-Bar]

Very tricky.
In my case, I unlinked and uninstalled and then installed & linked again, but version 3.1.2 (that doesn't have androidX).

Then I followed @engylemure helpful advice. However, I also had a firebase-analytics version 17.0.2 that I had to lower to 15.0.2 to get it to work.
