Android Material and appcompat Manifest merger failed

Android Material and appcompat Manifest merger failed - android

I have next grade
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.google.android.material:material:1.0.0-rc01'
}
But when I want to build app I get next log:
Manifest merger failed : Attribute application#appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0-alpha3] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0-alpha3] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.
Okey! Go to manifest and do it:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="ru.chopcode.myapplication">
<application
tools:replace="android:appComponentFactory"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
</application>
</manifest>
Then I get this error in my Logcat:
Manifest merger failed with multiple errors, see logs that I have Linked with it

I had similar problem. Added two lines in gradle.properties file:
android.useAndroidX=true
android.enableJetifier=true
These two lines automatically resolved my dependency conflicts between google's files and third party dependencies. Here's the link to follow: https://developer.android.com/topic/libraries/support-library/androidx-overview#new-project

I faced same error when i try to add Kotlin-KTX library to my project.
I try to AndroidX migration, and problem fixed!

Reason of Fail
You are using material library which is part of AndroidX.
If you are not aware of AndroidX, please go through this answer.
One app should use either AndroidX or old Android Support libraries.
That's why you faced this issue.
For example -
In your gradle, you are using
com.android.support:appcompat-v7 (Part of old --Android Support Library--)
com.google.android.material:material (Part of AndroidX) (AndroidX build artifact of com.android.support:design)
Solution
So the solution is to use either AndroidX or old Support Library. I recommend to use AndroidX, because Android will not update support libraries after version 28.0.0. See release notes of Support Library.
Just migrate to AndroidX.Here is my detailed answer to migrate to AndroidX. I am putting here the needful steps from that answer.
Before you migrate, it is strongly recommended to backup your project.
Existing project
Android Studio > Refactor Menu > Migrate to AndroidX...
It will analysis and will open Refractor window in bottom. Accept changes to be done.
New project
Put these flags in your gradle.properties
android.enableJetifier=true
android.useAndroidX=true
Check #Library mappings for equal AndroidX package.
Check #Official page of Migrate to AndroidX
What is Jetifier?

In my case, this is working perfectly..
I have added below two line codes inside manifest file
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"
Credit goes to this answer.

Simple Solutions - migrate into AndroidX
in the gradle.properties, just add below two scripts
android.useAndroidX=true
android.enableJetifier=true
What was the reason ↓
All packages in AndroidX live in a consistent namespace starting with the string androidx. The Support Library packages have been mapped into the corresponding androidx.* packages. For a full mapping of all the old classes and build artifacts to the new ones, see the Package Refactoring page.
Please see the Package Refactoring page

Just change "rc01" in first and last line inside dependencies to "alpha1"
This is working for me

Just remove the android.support dependancy
implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
Quoting From Material Guidelines
If you don’t want to switch over to the new androidx and com.google.android.material packages yet, you can use Material Components via the com.android.support:design:28.0.0-alpha3 dependency.
Note: You should not use the com.android.support and com.google.android.dependencies in your app at the same time.
Just removing this dependency works fine
implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
Here is complete dependencies example
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.material:material:1.0.0-beta01'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

As of Android P, the support libraries have been moved to AndroidX
Please do a refactor for your libs from this page.
https://developer.android.com/topic/libraries/support-library/refactor

See This Image and Add This line in your android AndroidManifest.xml
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

Please go to Refactor->Migrate->Migrate to Android X.
Please add this to your gradle.properties file:
android.enableJetifier=true
android.useAndroidX=true
And perform Sync.

Add these lines inside in AndroidManifest.xml file.
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

just add these two lines of code to your Manifest file
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

Migrate to androidX if it an existing project. If it is new project add these two flags to Gradle.propeties
android.enableJetifier=true
android.useAndroidX=true
for more detail steps https://developer.android.com/jetpack/androidx
or check this What is AndroidX?

Follow these steps:
Goto Refactor and Click Migrate to AndroidX
Click Do Refactor

Only If you don't want to use androidx
So in my case, I am using a library that was using androidx but I am not using androidx so when I downgraded that library version the problem was resolved.
In my Case:
implementation 'com.github.turing-tech:MaterialScrollBar:13.+'
the above-mentioned library makes problem 13.+ will automatically get a new version of the library which using androidx. So I downgraded library version to:
implementation 'com.github.turing-tech:MaterialScrollBar:13.2.5'
And the problem was resolved.

This issue mainly happened for old dependencies.
There have 2 solution:
First one:
Update all old dependencies and ClassPaths from Project level gradle files.
classpath 'com.android.tools.build:gradle:3.3.1'
classpath 'com.google.gms:google-services:4.2.0'
Second one:
Your project Migrate to AndroidX
From Android Studio Menu -> Refanctor -> Migrate to AndroidX
Thanks, let me know if anyone help from this answer.

Finally found a quick and easy solution by adding two lines in the android/build.gradle file.
googlePlayServicesVersion = "16.+"
firebaseVersion = "17.6.0"
Please follow this 100% correct.

Its all about the library versions compatibility
I was facing this strange bug couple of 2 hours.
I resolved this error by doing these steps
hange your build.gradle dependencies into
implementation 'com.google.android.gms:play-services-maps:17.0.0'
to
implementation 'com.google.android.gms:play-services-maps:15.0.0'

All I did was go to the "Refactor" option on the top menu.
Then select "Migrate to AndroidX"
Accept to save the project as a zip file.
Please update Android Studio as well as Gradle to ensure no problems are encountered.

Create new project and compare your build.gradle files and replaced all
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.1'
and other dependencies with the same as were in a new project
someting like that
implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0-alpha1'
androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'
implementation 'androidx.core:core-ktx:1.0.0-alpha3'
And then fixed imports to use androidx in kotlin files.

If you do not intend to migrate to AndroidX follow the below steps
In terminal type gradlew app:dependencies
After dependencies are shown in the window press Ctrl+f and type androidX
You will find all the dependencies which are using androidx lib internally you may have to downgrade that or use alternative for that to ensure it is no longer using androidX libs internally.

1.Added these codes to at the end of your app/build.gradle:
configurations.all {
resolutionStrategy.force 'com.android.support:support-v4:28.0.0'
// the above lib may be old dependencies version
}
2.Modified sdk and tools version to 28:
compileSdkVersion 28
buildToolsVersion '28.0.3'
targetSdkVersion 28
3.In your AndroidManifest.xml file, you should add two line:
<application
android:name=".YourApplication"
android:appComponentFactory="AnyStrings"
tools:replace="android:appComponentFactory"
android:icon="#drawable/icon"
android:label="#string/app_name"
android:largeHeap="true"
android:theme="#style/Theme.AppCompat.Light.NoActionBar">
Or Simply
Go to Refactor (Studio -> Menu -> Refactor)
Click the Migrate to AndroidX. it's working
it's working.

First of all be sure to add this line in manifest tag
xmlns:tools="https://schemas.android.com/tools"
Then add tools replace your suggested one in Android studio

Go to Refactor (Image )
Click the Migrate to AndroidX. it's working
it's working.

Try this
tools:replace="android:appComponentFactory"
android:appComponentFactory="android.support.v4.app.CoreComponentFactory"
Rebuild your project.

I had this same problem for three days.
It is like android wants us to either use Kotlin Or AndroidX, they are doing away with Android.
But this is how I solved it.
I migrated my project to AndroidX. This does not bring in any errors related to this issue in question, It updates files respectively. No method, class or variable name needs to be changed in your application.
NB: You must be using the latest Libraries (build.grudle file) in the latest stable version of android studio 3.4.1

I don't know this is the proper answer or not but it worked for me
Increase Gridle Wrapper Property
distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip
and Build Gridle to
classpath 'com.android.tools.build:gradle:3.4.2'
its showing error because of the version.

Change proguardFile in build.gradle (Module: app) to the following
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
instead of
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
This worked for me

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
}
reference
https://github.com/zo0r/react-native-push-notification/issues/1109#issuecomment-506414941

I'm also facing the same issue,
for your android studio, you just change the android Gradle plugin version 3.3.2
and Gradle version is 5.1.1

AndroidX dependencies error on adding firebase to android

I am working on an android project, When I tries to add firebase dependency to project following Build error occurs. I have tried migrating to appCompat but didnt workded.
This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry.The following AndroidX dependencies are detected: androidx.versionedparcelable:versionedparcelable:1.0.0, androidx.fragment:fragment:1.0.0, androidx.slidingpanelayout:slidingpanelayout:1.0.0, androidx.core:core:1.0.0, androidx.customview:customview:1.0.0, androidx.swiperefreshlayout:swiperefreshlayout:1.0.0, androidx.interpolator:interpolator:1.0.0, androidx.loader:loader:1.0.0, androidx.drawerlayout:drawerlayout:1.0.0, androidx.viewpager:viewpager:1.0.0, androidx.collection:collection:1.0.0, androidx.localbroadcastmanager:localbroadcastmanager:1.0.0, androidx.lifecycle:lifecycle-common:2.0.0, androidx.arch.core:core-common:2.0.0, androidx.annotation:annotation:1.1.0, androidx.legacy:legacy-support-core-ui:1.0.0, androidx.lifecycle:lifecycle-livedata:2.0.0, androidx.lifecycle:lifecycle-viewmodel:2.0.0, androidx.lifecycle:lifecycle-livedata-core:2.0.0, androidx.arch.core:core-runtime:2.0.0, androidx.legacy:legacy-support-core-utils:1.0.0, androidx.documentfile:documentfile:1.0.0, androidx.cursoradapter:cursoradapter:1.0.0, androidx.lifecycle:lifecycle-runtime:2.0.0, androidx.coordinatorlayout:coordinatorlayout:1.0.0, androidx.asynclayoutinflater:asynclayoutinflater:1.0.0, androidx.print:print:1.0.0

implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
Please help to resolve above issue.

android.useAndroidX=true
The Android plugin uses the appropriate AndroidX library instead of a Support Library.
android.enableJetifier=true
The Android plugin automatically migrates existing third-party libraries to use AndroidX by rewriting their binaries
Add both line in your gradle.properties file.
Then clean project and rebuild project.
May be your problem will be solved.
If not let me know.
You are currently using Android based library should be migrated to Androidx.
I suggest you migrate your project in Androidx.

gradle not syncing when adding firebase to android studio

So I'm trying to add the Firebase SDK to my Android Studio app as per the instructions from the Firebase website (see picture).
Adding the line classpath 'com.google.gms:google-services:4.3.2' to the project level gradle works fine. I can sync the gradle files.
However, adding the line apply plugin: 'com.google.gms.google-services' to the app level gradle file breaks my app.
I get the following error:
ERROR: Manifest merger failed : 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.
So i go to do the suggestion. I add tools:replace="android:appComponentFactory" to >application< element in AndroidManifest.xml file. This then gives me a Namespace "tools" not bound error. I press Alt+Enter to fix which adds xmlns:tools="http://schemas.android.com/tools" to the top of my file.
Try sync again. Now i get a similar error: ERROR: Manifest merger failed with multiple errors, see logs. And this is where I'm lost. I'm not sure what to search in Google. a search for this specific error brings up a lot of answers that aren't related to my problem. This territory is completely new to me.
P.S. On top of all that, the line implementation 'com.android.support:appcompat-v7:28.0.0'inside my build.grade(app level) file is underlined red after adding the previously mentioned 3 lines.
I noticed there's other questions related to this but none seem to have solid answers. So I'm taking the risk that this might be a repost.
EDIT::
Here are my gradle depencies.
Project Gradle
dependencies {
classpath 'com.android.tools.build:gradle:3.5.2'
classpath 'com.google.gms:google-services:4.3.2'
}
App Gradle
dependencies {
implementation 'com.google.firebase:firebase-analytics:17.2.0'
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0'
}
EDIT 2::
Ok after migrating to androidx, I updated all my import statements to use androidx. It still kept saying merger failed with multiple errors. I had to delete the line tools:replace="android:appComponentFactory" that it had previously suggested to add. Finally I was able to sync and run my app! Except now the app just starts and stops immediately. I suppose that's progress. Any ideas on this?
EDIT 3::
I finally got it to work. The last issue was a RunTimeError "Error inflating class androidx.constraintlayout.ConstraintLayout". This is caused because all my xml files had the line androidx.constraintlayout.ConstraintLayout. replaced this with the line androidx.constraintlayout.widget.ConstraintLayoutand everything is gravy now. Gradle syncs, app loads, doesn't crash and everything works as it's supposed to
Any help would be greatly appreciated.
Thx in advance,
Vlad

The problem is your app is using android.support libraries while the Firebase sdk you added to your project uses AndroidX.
Note: AndroidX and android.support are not compatible.
So you have to either migrate your project to AndroidX or use a support version of Firebase.
Migrate code to use AndroidX
From Refactor option choose Migrate to Androidx.
Sync the project and you should be fine.
Use a Non-Androidx firebase.
Go to Firebase release notes
Find the last version that is before migrating library to AndroidX (For instance Firebase messaging 19 uses androidx and lower versions don't)
TL;DR
Migrate to AndroidX or use a lower version library of Firebase.

In your application tag add tools:replace="android:appComponentFactory"
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:replace="android:appComponentFactory"
>
then gradle.properties add
android.enableJetifier=true
android.useAndroidX=true
