Android gradle build failed with an exception when include firebase and gms service

Question

I just created an empty android project while including the dependencies I need for the project I got an error only when I add com.google.firebase or com.google.android.gms it will generate error below.

/Users/macbookair/Desktop/ANDROID/APPTEST/app/src/main/AndroidManifest.xml:22:18-91 Error: Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:5:5-21:19 to override.

Please can anyone help me out, I have be trying for very long time to fix this error.

apply plugin: 'com.android.application'
android {
 compileSdkVersion 28
 defaultConfig {
 applicationId "com.fexample.android.appz"
 minSdkVersion 18
 targetSdkVersion 28
 versionCode 2
 versionName "2.0"

 }
}

 useLibrary 'org.apache.http.legacy'
}
apply plugin: 'com.google.gms.google-services'
android { sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/public'] } } }

From the below screenshot this implementation 'com.android.support:appcompat-v7:28.0.0' also has an error but when I build apk it create successfully, I don't think is good.

Dependencies using groupId com.android.support and androidx.* can not be combined but found IdeMavenCoordinates{myGroupId='com.android.support', myArtifactId='support-fragment', myVersion='28.0.0', myPacking='aar', myClassifier='null'} and IdeMavenCoordinates{myGroupId='androidx.swiperefreshlayout', myArtifactId='swiperefreshlayout', myVersion='1.0.0', myPacking='aar', myClassifier='null'}

Answer 1

I'll suggest you try one of the following:

1) Migrate the whole project to use the androidx libraries which you can do under Refactor> Migrate to AndroidX from the menu bar.

2) Downgrade the versions of com.google.firebase and com.google.android.gms from 17.x.x to a lower version

• Peter: I just tried the downgrade and it worked but the error here implementation 'com.android.support:appcompat-v7:28.0.0' is the there
• Mayokun: Awesome, now i'll advise you migrate the whole project to use the androidx libraries like I suggested above
• Peter: Okay, by doing this migration will it affect supported device? Because am creating this new test project to see why supported device was dropped in my existing project when I upload the apk and to make a clean project too
• Mayokun: No, the migration won't affect supported devices.
• Peter: Sorry that I delayed, implementation 'androidx.appcompat:appcompat:1.0.0' androidTestImplementation 'androidx.test:runner:1.1.0' androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0' now it worked so should I go ahead and upgrade those to new version?
