Android Material and appcompat Manifest merger fai

问题:

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

回答1:

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

回答2:

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

回答3:

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

I try to AndroidX migration, and problem fixed!

回答4:

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?

回答5:

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.

回答6:

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

回答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'
   }

回答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

回答9:

Add these lines inside in AndroidManifest.xml file.

tools:replace="android:appComponentFactory"

android:appComponentFactory="whateverString"

回答10:

Follow these steps:

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

回答11:

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

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

回答12:

just add these two lines of code to your Manifest file

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

回答13:

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.

回答14:

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'

回答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.

回答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.

回答17:

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.

回答18:

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

回答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.

回答20:

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.

回答21:

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.

回答22:

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

回答23:

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

回答24:

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.

回答25:

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

回答26:

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')

回答27:

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.

回答28:

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

回答29:

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
}

回答30:

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
