Android Fixing Manifest Error - manifest merger failure

When included a new Android Library module, got the conflict below. This happens when the Manifest merge fails between the module and the Application.

Error:(10, 9) Attribute application@label value=(IoT League) from AndroidManifest.xml:10:9

Error:(10, 9) Execution failed for task ':app:processDebugManifest'.

> Manifest merger failed : Attribute application@label value=(MyTestApp) from AndroidManifest.xml:10:9

  is also present at MyTestApp2:mytestlib:unspecified:13:9 value=(@string/app_name)

  Suggestion: add 'tools:replace="android:label"' to element at AndroidManifest.xml:7:5 to override

To solve it, below can be added in the application manifest 

"http://schemas.android.com/apk/res/android"

package=“com.testapp” xmlns:tools="http://schemas.android.com/tools"

android:allowBackup="true"

android:icon="@drawable/ic_launcher"

android:label=“MyTestApp2”

android:theme="@style/AppTheme"

tools:replace="android:label"
