Question

I am using Android studio 2.3 and Thought for support new android 26 in my app.But I am stuck on error with title message. My gradle file is like below

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"



    defaultConfig {
        applicationId "com.example.shayari"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"

        manifestPlaceholders = [onesignal_app_id               : "",
                                // Project number pulled from dashboard, local value is ignored.
                                onesignal_google_project_number: "REMOTE"]

        vectorDrawables.useSupportLibrary = true
    }



    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')

    compile 'com.google.android.gms:play-services-location:10.2.6'
    compile 'com.android.support:support-v4:26.0.0'

    flatDir {
        dirs 'libs'
    }
}

Add this to your project level build.gradle file:

repositories {
    maven {
        url "https://maven.google.com"
    }
}
