Suggestion: add ‘tools:replace=»android:appComponentFactory»‘ to element

jaredrummler commented Jan 16, 2019

Are you sure this is related to the library? It isn’t using IconCompatParcelizer

Android X: tools:replace specified at line: for attribute, but no new value specified

I have tried many solutions on this website but still, the problem is not solved. The issue is due to Android X library. When I added Android X, this issue was resolved but it opened up new issue. How to fix this issue?

Earlier this error was coming:

After I added tools:replace=»android:appComponentFactory» , this error is came:

Merging Error (in Android Manifest):

Error: tools:replace specified at line:2 for attribute android:appComponentFactory, but no new value specified app main manifest (this file), line 1

I think you are migrating to AndroidX libs.

Add below lines to gradle.properties file

Remove tools:replace=»android:appComponentFactory» from manifest.

Replace android.support.v7.app.AppCompatActivity to androidx.appcompat.app.AppCompatActivity

You can try adding:

I got same error in my project, I have resolved it You can try it

Android Studio > Refactor > Migrate to AndroidX

In my case, I had updated Firebase and play services dependency, result in this issue.

Reverted back the dependency updates and the error vanished

Seems that the latest Firebase and Play Service dependencies are compatible with androidx.

It often happened because you used Androidx libraries and support libraries at the same time. Some 3rd-party libraries may contain support libraries and other 3rd-party libraries may contain Androidx libraries, this can also lead this problem. If you have gradle environment in you PC, try «gradlew :app:dependencies» command in the terminal of Android Studio, this command will list all libraries including 3rd-party libraries of your project, and see which library or framework used Androidx libraries and which not. Then try to upgrade old libraries used support libraries, and this problem should disappear.

Manifest Merger fails for appComponentFactory [duplicate]

Using Google’s so called Material Design 2.0 requires you to add

in the app Gradle which also includes

which shows conflicts

Here’s what the log says

Even after adding that to the Manifest it shows Manifest Merger failed with multiple error

This error is common nowadays:

When we get this types of error: When library is updated and providing use of AndroidX but we are using old one.

You can follow the steps to solve this:

• Migrate your project to AndroidX:

With Android Studio 3.2 and higher, you can quickly migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

Note: To migrate an existing project that does not use any third-party libraries with dependencies that need converting, you can set the android.useAndroidX flag to true and the android.enableJetifier flag to false.

THIS STEP WILL DO EVERYTHING AUTOMATICALLY THAT ALL ANSWER SAYS TO DO MANUALLY

• You can check Overview of AndroidXhere.
• More details for migration

Even If you get any other error like run-time build failed, then:

• Invalidate cache and restart

Put these flags in your gradle.properties

After hours of struggling, I solved it by including the following within app/build.gradle:

Put these flags in your gradle.properties

Changes in build.gradle:

Reason of this error-

Because after upgrade, androidx.core:core is accessed somewhere, when your project is still not using androidx. So classes like CoreComponentFactory and many others are now found at two places — androidx.core:core and com.android.support:support-compat . That’s why this error occured.

What is solution?

You should migrate to AndroidX. If you don’t know about AndroidX. Please read What is AndroidX?

How to migrate your project

After Android Studio 3.2 (September 2018), there is direct option to migrate existing project to AndroidX . This refract all packages automatically.

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

Error explicitly says-

[com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0]

AndroidX is the latest support library from Google. It contains all previous components from all older appcompat versions. Do NOT use appcompat-v-any number. Instead, use a similar component from AndroidX libraries. Remove the numbered support libraries from your Gradle and your code wherever it is imported. Then sync your gradle.

Component similarity table can be found here. Also, follow the steps mentioned in Migrating to AndroidX.

Again, stop using any previous appcompat numbered versions. There’s only AndroidX now.
