Android Material 和 appcompat Manifest 合并失败

Question

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

Answer 1

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

Answer 2

I faced same error when i try to add Kotlin-KTX library to my project.

I try to AndroidX migration, and problem fixed!

Answer 3

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?

Answer 4

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 .

Answer 5

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

Answer 6

只需将依赖项内第一行和最后一行中的“rc01”更改为“alpha1”这对我有用

Answer 7

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'
   }

Answer 8

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

Answer 9

See This Image and Add This line in your android AndroidManifest.xml

tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

Answer 10

Add these lines inside in AndroidManifest.xml file.

tools:replace="android:appComponentFactory"

android:appComponentFactory="whateverString"

Answer 11

1. Please go to Refactor->Migrate->Migrate to Android X.

2. Please add this to your gradle.properties file:

    android.enableJetifier=true android.useAndroidX=true

And perform Sync.

Answer 12

just add these two lines of code to your Manifest file

tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

Answer 13

Follow these steps:

• Goto Refactor and Click Migrate to AndroidX
• Click Do Refactor

Answer 14

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?

Answer 15

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.

Answer 16

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.

Answer 17

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.

Answer 18

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'

Answer 19

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.

Answer 20

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.

Answer 21

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.

Answer 22

If you do not intend to migrate to AndroidX follow the below steps

1. In terminal type gradlew app:dependencies
2. After dependencies are shown in the window press Ctrl+f and type androidX
3. 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.

Answer 23

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

Answer 24

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

Answer 25

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

Answer 26

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.

Answer 27

Try this

tools:replace="android:appComponentFactory"
android:appComponentFactory="android.support.v4.app.CoreComponentFactory"

Rebuild your project.

Answer 28

I had the same error when working with Groupie (implementation 'com.xwray:groupie:2.3.0')

I solved it by changing version to (implementation 'com.xwray:groupie:2.1.0')

Answer 29

In may case I didn't want to pass to androidX. And I have to check my last changes. I figure out that the new component was --> lottie 2.8.0 So I downgrade it to: implementation 'com.airbnb.android:lottie:2.7.0'

I hope that this may help someone.

Answer 30

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

Answer 31

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
}

Answer 32

我也面临同样的问题，对于您的 android studio，您只需更改 android Gradle 插件版本 3.3.2，Gradle 版本为 5.1.1

Answer 33

I have next grade

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0-rc01'

    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

        android:supportsRtl="true"
        android:theme="@style/AppTheme">

</manifest>

Then I get this error in my Logcat:

Manifest merger failed with multiple errors, see logs that I have Linked with it

Answer 34

go to manifest file delete this line

 xmlns:tools="http://schemas.android.com/tools"

and add this line

 xmlns:android="http://schemas.android.com/apk/res/android"
