React Native Android: Manifest merger failed

When I am running the command react-native run-android in the terminal
(React-Native), I am getting the below-mentioned error.
Manifest merger failed : Attribute application#appComponentFactory
value=(andr
oid.support.v4.app.CoreComponentFactory) from
[com.android.support:support-compa
t:28.0.0] AndroidManifest.xml:22:18-91 is also present at
[androidx.core:core:1.1.0-alpha05] AndroidManifest.xm
l:22:18-86 value=(androidx.core.app.CoreComponentFactory).
I tried migrating from android.support to android x as per the solution stated by few.
Expected Result: Build SuccessFul
Actual Result: BUILD FAILED in 9s

Can you try adding below in gradle.properties:
android.useAndroidX=true
android.enableJetifier=true
It will automatically resolve dependency conflicts between google's files and third-party dependencies.

see Manifest merger failed after import a module if this option doesnt work rather than upgrading to android X now.

How to fix Execution failed for task ':app:processDebugManifest' in React Native?

I find an error when run the project, I try to look for many examples but fail all, this is the detail of error:
D:\myApp\android\app\src\debug\AndroidManifest.xml:22:18-91 Error:

Please anyone help me to solve this problem.
Thanks

So I faced this issue while installing react-native-reanimated in order to make react-navigation-drawer working.
The fix was:
Add to android/gradle.properties:
android.enableJetifier=true
android.useAndroidX=true
yarn add jetifier
In android directory run:
./gradlew clean
Run:
yarn jetify
react-native run-android
My RN version 0.59.8

Upgrading 'react-native-device-info' to version 2.1.2 fixed the error for me.
See http://github.com/facebook/react-native/issues/25294#issuecomment-503024749

I had some more libraries(other than deviceinfo) that depended on gcm so I used this to fix the issue: https://stackoverflow.com/a/56648987/8306924

finally found a solution after 2days and just added below two lines to android/build.gradle
googlePlayServicesVersion = "16.+"
firebaseVersion = "17.3.4"

You just have to edit "gradle.properties" and add:
android.useAndroidX=true
android.enableJetifier=true
So you resolved the dependency conflicts between google and third party dependencies.

I downgraded java version from 17 to 15 and it works

i had the same issue and changed version of gradle on android > build.gradle and fixed my problem
classpath("com.android.tools.build:gradle:4.2.2")
to
classpath("com.android.tools.build:gradle:7.1.1")
clean gradle and build again
in android directory command prompt:
#gradlew clean
#gradlew build

The solution to the Execution failed for task :app:processDebugMainManifest’ in React Native Android project for JDK 16, 17, and above is to add the following line in the ./android/gradle.properties file in your project:
org.gradle.jvmargs=--add-opens java.base/java.io=ALL-UNNAMED

AndroidManifest error related to AndroidX when trying to build React Native 0.59 app

I'm trying to build a React Native Android application following an upgrade to RN 0.59.9, but I'm getting an error related to AndroidX.
I've tried many things including removing most native packages, changing AndroidManifest.xml and various other solutions mentioned on the internet but nothing seems to work.
My error is this:
> Task :app:processReleaseManifest FAILED
....\android\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 <application> element at AndroidManifest.xml:35:2-108:16 to override.
See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.
FAILURE: Build failed with an exception.
As I understand it means one of the package uses AndroidX but not the main app, however as far as I can tell nothing in my app uses AndroidX, and I made sure to upgrade to RN 0.59, not 0.60. I've even tried to grep "androidx" and remove all the packages that might mention it.
I've also tried to add "android.useAndroidX=true / android.enableJetifier=true" to gradle.properties just to see what happens but as expected many modules don't build since they have not been upgraded to AndroidX.
Any idea how to fix this bug?

This is most likely due to Android releasing all AndroidX libraries, and '+'-style gradle dependencies leaking in.
You can either ./gradlew :app:dependencies|grep androidx to find the problem libraries and then use gradle resolutionStrategies or android/build.gradle ext{} versioning to pin the Google library dependency, or you can convert your react-native project to androidx and use the jetifier tool via npm i jetifier && npx jetify so that non-androidx react-native libraries work.
Either should result in a working build as the react-native ecosystem transitions to AndroidX

React native "Execution failed for task: ':app:processDebugManifest' after adding Admob module

Working with a React Native project and ready for release but running into this error:
Execution failed for task ':app:processDebugManifest'.
> 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

Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:7:5-117 to override.
Works fine before adding the "react-native-admob" module through npm using "npm i --save react-native-admob#next"
In order to complete the project I need admob running! help please!

You are having this issue because your dependencies are depending on android support libaries. some have the older version named eg. 'com.android.support..', while some depend on the newer androidX library with names 'androidx.core....'. Having both com.android.support and androidx libaries in the same project will prevent the app from building.
This issue likely arose from the June 17 update to google play services which included major breaking changes to android support libraries. https://developers.google.com/android/guides/releases.
To fix this issue, identify all yr react-native packages and check if they have dependencies (listed under the play services release notes) that have been forceably updated to the newest version which gives androidx. If you have the android folder in the project that holds your build.gradles, try cd android, and then run ./gradlew app:dependencies --scan. This generates a unique link to a report for you to inspect each packages' dependencies. Expand your dependencies and make sure react-native packages when fully expanded do not contain any androidx file. Check all paths, testCompileClasspath, testRuntimeClassPath....
If you do have affected dependencies, you will need to force those packages to use the older version with com.android.support. This issue link has several suggestions on how to implement. https://github.com/facebook/react-native/issues/25292
I fixed this issue happening with our builds couple days back by doing stuff similar to this in my app/build.gradle:
implementation(project(':react-native-camera')){
exclude group: 'com.google.android.gms'
}
You might also need to declare some top-level configuration to force google play service and firebase to use specific version.
The official documention on androidx recommends people to switch to using the newer library androidx, and tell you to enable androidX and Jettifier to true. This DOES NOT work 100% for react-native libraries. So don't upgrade packages to androidx until you are sure all dependencies you have in your project are eligible for the migration to androidx.

Gradle - A problems occurred evaluating root project '*'. > Could not find method compile() for arguments [*] on root project '*'

I'm using Eclipse Luna to develop my Android app. I don't have any idea why the error message keep showing again and again. I got this error message after fill up dependencies in build.gradle and run gradle build in my terminal.
build.gradle

BUILD FAILED

change to this:
compile 'com.lorentzos.swipecards:library:1.0.8'

I encountered the error when I tried using gradle 2.6 to build a project that was built using gradle 2.3. Make sure the versions are the same.

The compile task is defined by the java plugin. However, as you do not include it in your root project it does not exist there so gradle does not know how to handle it.
In order to resolve it you can either:
Apply the java plugin to your root project. The downside of this approach would be that this plugin will be included automatically in all your sub project that in somecases may be undesired, and also by default there will be an empty jar created for this project.
Define a dummy empty compile task yourself so gradle will be happy.

compile is a dependency configuration that comes from the Java Plugin.
The Android Gradle plugin applies the Java plugin under the covers. I do not see the Android plugin applied in your Gradle script. I think you may be missing a module-level build configuration that applies the Android Gradle plugin which would add dependencies.compile(...) to the DSL.
