I bought a new macbook pro
i have installed all the latest stuff from android studio in my laptop from the stable channel

i am not able to successfully build my project gradle when i add
implementation 'com.google.android.material:material:1.0.0-rc01'

gradle
`apply plugin: 'com.android.application'

android {
compileSdkVersion 28
defaultConfig {
applicationId "com.silverpants.todolist"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

`
errror it shows is

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0-rc01] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0-rc01] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:5:5-19:19 to override.

and when i take its suggestion an error appears like this
code

Duplicate of #103.

This is because you are using the new Material library with the legacy Support Library. You have to migrate android.support to androidx in order to use com.google.android.material.

Please take a look at our Getting Started Guide which talks about this.

[sammrabatool]

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:5:5-19:19 to override.

[sammrabatool]

i have this error i want to show a barchart

[blessingofallah]

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.

[bukunmialuko]

I got a similar problem when using a new library,
I fixed the problem by migrating the project to androidx

The new android studio does the migration smoothly just click on Refactor-->migrate to androidx-->It will ask you to back up-->then do refactor.

Watch this tutorial, hope it helps.

[PGMacDesign]

@bukunmialuko One issue I am having is that if I try your method, it indicates you need to be on Gradle 3.2.0 or higher, but switching to that version causes this exception:
https://stackoverflow.com/a/52608833/2480714
Which does not seem to have a working solution other than downgrading gradle.

[bukunmialuko]

Update all your dependencies after migrating to androidx.

[drachomi]

The error usually occurs whenever you use AndroidX with legacy support dependencies.
To solve it, just add the following line in your gradle.properties file:
android.enableJetifier=true
android.useAndroidX=true

[sandeepmaxpayne]

still error exists

[IDFDeveloper]

I am just extending the answer that
Add this implementation 'com.google.android.material:material:1.0.0' dependency and
Remove this dependency implementation 'com.android.support:appcompat-v7:28.0.0' from module level gradle file and its working for me.

I hope some one will get help.

[Harishn28]

As of Android P, the support libraries have been moved to AndroidX.

so remove com.android.support dependecies and move them to use android x namespace.

more details @ https://developer.android.com/jetpack/androidx/migrate

[androidqasim]

add these lines in the manifiest

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

[iamjpsharma]

The error usually occurs whenever you use AndroidX with legacy support dependencies.
To solve it, just add the following line in your gradle.properties file:
android.enableJetifier=true
android.useAndroidX=true

this one workeed

Can you please tell me where to add these two line in gradle?

[dsn5ft]

They can be added anywhere in your gradle.properties file.

I had a similar problem.
solution for me was to change the version of react-native-device-info from 0.21.5 to 2.1.2.
after changing this I got this error.

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:preDebugBuild'. Android dependency 'com.android.support:support-media-compat' has different version for the compile (27.0.2) and runtime (28.0.0) classpath. You should manually set the same version via DependencyResolution

And then added the following code in android/build.gradle in subprojects section

subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "26.1.0"
}
}
}
}

then it works for me

[Gnkumararaja]

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.

It's Working thanks...

[abdussamad123]

After use, all the above suggestions my Error still exists. can anyone help me, please?

[ziarno]

Was having this issue in a ReactNative project - I used the "Migrate to AndroidX" option in Android Studio, and all it did was:

1. Add

android.useAndroidX=true
android.enableJetifier=true

at the bottom of the file android/gradle.properties

1. Replace the line
   implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
   with
   implementation 'androidx.appcompat:appcompat:1.0.0'
   in android/app/build.gradle

Works great for me after this change

[nikopolidi]

in my react-native app I solved it that way:

yarn upgrade --pattern react-native solved my issues
Refactoring to androidx only created cascades of issues
I had no androidx dependencies in build.gradle file, but had some inside node_modules.
I stayed up with "com.android.support:appcompat-v7:28.0.0"

[madgreasemonkey]

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.

My app crashed after writing these two lines

[send2abhishek]

I had similar problem. Added two lines in gradle.properties file:

android.useAndroidX=true
android.enableJetifier=true

Add this two lines of code in Gradle.properties files

[buddhiv]

The error usually occurs whenever you use AndroidX with legacy support dependencies.
To solve it, just add the following line in your gradle.properties file:
android.enableJetifier=true
android.useAndroidX=true

worked! thanks.. Build is successful. Yet don't know if there is any runtime issues. I ll update if there is any.

[barakucrut]

if another error still exist, you can try this way :

1. npm install --save-dev jetifier
2. npx jetify

[bhogteyash99]

I just added
android.useAndroidX=true
android.enableJetifier=true
to gradle.properties and it resolved my issue.

[AliYar-Khan]

My app was working fine and then I installed react-native-push-notification library and now I'm getting this error as my Gradle files are not syncing.

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

    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at manifestMerger5259550878296044450.xml:7:5-9:19 to override.

My issue is not with Material and I tried every mentioned solution but still facing same error even when I remove the dependencies of that library.

[jairhumberto]

This gradle is the worst thing in Android, NEVER works fine; if you get your project and move from one computer to another, you have headache.

[jairhumberto]

Then you have to do some sort of hack to get it to work... like adding these two properties. This thing really need improvement.

[sandeepmaxpayne]

Hey need help ping me

Those two properties need to be defined in a gradle.properties file at the root of your project, not in your build.gradle.

android.useAndroidX=true
android.enableJetifier=true

[milesmeow]

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.

I needed to also follow this:
https://github.com/facebook/react-native/issues/25483#issuecomment-520344889.

The combination of adding those lines to gradle.properties worked for me!

:(
Already I used Android Studio to migrate my project to AndroidX. It automatically adds the 2 lines in gradle.properties and replaces all android support libraries to the new AndroidX but I continue having the same issue.

[khatzie]

Was having this issue in a ReactNative project - I used the "Migrate to AndroidX" option in Android Studio, and all it did was:

1. Add

android.useAndroidX=true
android.enableJetifier=true

at the bottom of the file android/gradle.properties

1. Replace the line
   implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
   with
   implementation 'androidx.appcompat:appcompat:1.0.0'
   in android/app/build.gradle

Works great for me after this change

This solve my problem.. 👍👍👍👍👍👍👍

[androidcode33]

The error usually occurs whenever you use AndroidX with legacy support dependencies.
To solve it, just add the following line in your gradle.properties file:
android.enableJetifier=true
android.useAndroidX=true

worked for me

Works like a charm !

[sandeepa91]

After adding
android.useAndroidX=true
android.enableJetifier=true
it solved and added androidx classes for all layouts
androidx.constraintlayout.widget.ConstraintLayout
androidx.drawerlayout.widget.DrawerLayout
Thank you @dsn5ft dsn5ft

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:5:5-19:19 to override.

not geetin the problem plzz help.

[hyunjkim]

For anyone who isn't using Androidx and if you're using proguard, I see that adding this line in your proguard helped without adding anything to the manifest:

Proguard.flags https://android.googlesource.com/platform/packages/apps/Settings/+/master/proguard.flags#58

-keep class androidx.core.app.CoreComponentFactory

I got the same error

Android Studio>Refactor>Migrate to AndroidX
Then Do Refactor.

This solves my problem.

[RashmiShrestha]

build.gradle

• use only one in bulid.gradle '1' or '2'
  1) implementation 'com.android.support:appcompat-v7:28.0.0'
  (or)
  2) implementation 'androidx.appcompat:appcompat:1.1.0'

• incase if you have
  implementation 'com.google.android.gms:play-services-maps:$suitable_version
  example:- implementation 'com.google.android.gms:play-services-maps:16.0.0'

[NiklasWilson]

Doing the refactor, works but you have to do it every single time.
The file below get overwritten each time.
android/capacitor-cordova-android-plugins/build.gradle
Replacing the androidx line with appcompat-v7
