More than one file was found with OS independent path

Question

I am working with the library:

    implementation 'androidx.appcompat:appcompat:1.0.0-rc02'

I am trying to integrate com.google.android.material.bottomappbar.BottomAppBar but when I run the application it returns the following error:

More than one file was found with OS independent path 'META-INF/androidx.vectordrawable_vectordrawable.version'

Gradle:

apply plugin: 'com.android.application'
android {
compileSdkVersion 28

    applicationId "gregorio.com.mx.ejemplo"
    minSdkVersion 17
    targetSdkVersion 28

Thank you very much, I hope you can help me resolve my question.

Answer 1

Goto to yourProject/app/build.gradle inside android{}

android { 
        packagingOptions { 
            pickFirst 'the/NameOfThe/lib.so' 
            pickFirst '**/*.so' //if you dont know the name of the library
        } 
    }

Answer 2

You're using two distinct but related versions of appcompat which is causing the conflict error. From your app-level build.gradle:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'androidx.appcompat:appcompat:1.0.0-rc02'

You're using both the old support version and the new androidx version side by side. Both contain the file META-INF/androidx.vectordrawable_vectordrawable.version. Use one or the other, but not both.

You're using a number of older support libraries which may conflict with Androidx libraries. You can see which support libraries can be moved to Androidx by looking at the Migrating to AndroidX documentation.
