how to fix mixed versions - error in build.gradle (Module:app) implementations (android studio)

Question

I'm building a simple app, and my build.gradle (Module App) has all the default code:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "gr.aegean.icsd.samossellbuy"
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0' // line 23
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    compile 'com.facebook.android:facebook-android-sdk:[4,5)'
}

When i compile and run the app into the emulator it crashes immediately

Error Message line 23:

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 26.1.0, 25.3.1. Examples include com.android.support:animated-vector-drawable:26.1.0 and com.android.support:cardview-v7:25.3.1 less... (Ctrl+F1) There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.

I'm completly new in Android Studio , I tried to be as much detailed as i could.

Thanks for your time!

phill i hope have posted full gradle file from app folder, because buildToolsVersion is missing and the error you are pointing seems to be ok. can you post the error you are getting now after build tool version update — vikas kumar, Nov 28 '17 at 16:59

Try changing the implementation to compile.

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 26
        buildToolsVersion "26.0.0"
        defaultConfig {
            applicationId "gr.aegean.icsd.samossellbuy"
            minSdkVersion 19
            targetSdkVersion 26
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:appcompat-v7:26.1.0' // line 23
        compile 'com.android.support.constraint:constraint-layout:1.0.2'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test:runner:1.0.1'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
        compile 'com.facebook.android:facebook-android-sdk:[4,5)'
    }

the app when i run the emulator still crashes:/ – Mr.Nois Nov 28 '17 at 17:12
I hope you are not making changes in top-level build.gradle instead it should be in module level build.gradle – vikas kumar Nov 28 '17 at 17:12
