No resource identifier found for attribute '…' in package 'com.app…'

Question

I\'ve imported a project from Eclipse to Android studio. It utilizes a custom view:

xmlns:app="http://schemas.android.com/apk/res-auto"

Answer 1

I was facing the same problem and solved it using the below steps:

Add this in your app's build.gradle

android {
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }
}

Use namespace:

xmlns:app="http://schemas.android.com/apk/res-auto"

Then use:

app:srcCompat="@drawable/your_vector_drawable_here"
