Answer 1

May be this problem is due to facebook library. Replace

compile 'com.facebook.android:facebook-android-sdk:[4,5)'

by

compile 'com.facebook.android:facebook-android-sdk:4.26.0'

Answer 2

Google's new Maven repo is required for the latest support library that is compatible with Android 8.0. Just update your Google's Maven repository like below:

To add them to your build, add maven.google.com to the Maven repositories in your module-level build.gradle file:

repositories {
    maven {
        url 'https://maven.google.com'
        // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
    }
}

Alternative you can update build.gradle file like this:

    repositories {
        jcenter()
        google()
    }

Then add the desired library to your dependencies block. For example, the cardview library looks like this:

dependencies {
    compile 'com.android.support:cardview-v7:26.1.0'
}

Answer 3

Use compile 'com.android.support:cardview-v7:25.4.0'
If you want version 26 you should use compile 'com.android.support:cardview-v7:26.0.0-beta2', because it is beta for now

Answer 4

try to compile

 compile 'com.android.support:cardview-v7:25.3.1'

Answer 5

Starting from version 26 of support libraries make sure that the repositories section includes a maven section with the "https://maven.google.com" endpoint.

Something like;

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

Answer 6

Update your Android Support Repository from sdk manager.
