ERROR:

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.1.0) from [com.android.support:support-v13:26.1.0] AndroidManifest.xml:28:13-35 is also present at [com.android.support:cardview-v7:26.0.2] AndroidManifest.xml:25:13-35 value=(26.0.2). Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:26:9-28:38 to override.

First you may add missing buildToolVersion below compileSdkVersion then use same version also missing compile 'com.android.support:recyclerview-v7: version so add this check below code

      android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1" //change here
    defaultConfig {
        applicationId "com.aparna.search_recy"
        minSdkVersion 21
        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'])
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:support-v13:26.1.0'
    implementation 'com.android.support:design:26.1.0'
    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.mcxiaoke.volley:library:1.0.19'
    compile 'com.android.support:recyclerview-v7:26.1.0' //change here
    compile 'com.android.support:cardview-v7:26.1.0'
}

finally clean and rebuild project if this not worked goto File->Invalidate Caches / Restart
