The prefix "tools" for attribute "tools:replace" associated with an element type "activity" is not bound.

Hi,
Followed android installation instructions. All looks good, until I try to build.

I get the "tools" error and everything stops:

[Fatal Error] :37:65: The prefix "tools" for attribute "tools:replace" associated with an element type "activit
y" is not bound.

FAILURE: Build failed with an exception.

• What went wrong:
  Exception while parsing the supplied manifest file D:_mobidev\app\android\app\src\main\AndroidManifest.xml

The prefix "tools" for attribute "tools:replace" associated with an element type "activity" is not bound.

In manifest, I have this, which is the referenced line in the error:

<activity tools:replace="android:theme"
			android:name="com.facebook.FacebookActivity"
			android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
			android:label="@string/app_name"
			android:theme="@android:style/Theme.Translucent.NoTitleBar"/>

Any ideas?

Did you add the xmlns:tools="http://schemas.android.com/tools" inside AndroidManifest.xml?

Specifically,

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.YOUR_APP_NAME"
    android:versionCode="2"
    android:versionName="2.0.1">

Hmm... I uninstalled react-native-facebook-login and left it for later after struggling for several hours. I can't specifically answer yes or no to that question except to say I had followed all the steps as per instructions. If I run into the same issue when I reinstall I will comment. Thanks.

I tried to replicate again and I believe my solution is wrong. What made it build, after having the same error as you, was to just remove the line

tools:replace="android:theme"

Hope this helps.

please use master and not the version on npm. should resolve issue as well as using @pmadruga original solution.

Also see deprecation notice in readme

Just reporting back to help others. I did try to install again, and this time, from master. "Worked" out of the box in the sense that I wasn't getting the error anymore. Instead other issues, namely: #64 finally got me to just uninstall and move on to other modules.
I will try https://github.com/facebook/react-native-fbsdk instead.
Thanks for the help.

@lwhiteley is this still what you recommend? To not install from npm?

@pmadruga I get an error that tools:replace="android:theme" is needed.

@SelaO To fix this, add xmlns:tools="http://schemas.android.com/tools" to the <manifest> header.

This works for me.

Add tools:node="replace" to <application/> tag.

I'm having a similar problem while trying to create a checklist app.

In my build.gradle (Module:app) I was instructed to add

implementation 'androidx.recyclerview:recyclerview:1.1.0'
&
implementation 'com.google.android.material: material:1.1.0'

This gave me error Manifest merger failed and suggested that I add

tools:replace="android:app component factory"

to my element in my AndroidManifest.xml. I also added

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

to my element to make it work, but now I'm getting several log errors that primarily focus on "Couldn't load memtrack module".

I think it is worth mentioning here that this line should be added inside the starting manifest tag.
My mistake was that I added it after the starting manifest tag was closed.

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