Your compile SDK version must match the support library. so do one of the following:
1.In your Build.gradle
change
compile 'com.android.support:appcompat-v7:23.0.1'
2.Or change:
compileSdkVersion 23
buildToolsVersion "23.0.2"
to
compileSdkVersion 25
buildToolsVersion "25.0.2"
As you are using : compile 'com.android.support:appcompat-v7:25.3.1'
i would recommend to use the 2nd method as it is using the latest sdk – so you can able to utilize the new functionality of the latest sdk.
Latest Example of build.gradle with build tools 27.0.2 — Source
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
buildToolsVersion "27.0.2"
defaultConfig {
applicationId "your_applicationID"
minSdkVersion 15
targetSdkVersion 27
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'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:27.0.2'
compile 'com.android.support:design:27.0.2'
testCompile 'junit:junit:4.12'
}

EDIT
if you are using Facebook Account Kit
don’t use: compile 'com.facebook.android:account-kit-sdk:4.+'
instead use a specific version like:
compile 'com.facebook.android:account-kit-sdk:4.12.0'
there is a problem with the latest version in account kit with sdk 23
EDIT
in your build.gradle
instead of:
compile 'com.facebook.android:facebook-android-sdk: 4.+'
use a specific version:
compile 'com.facebook.android:facebook-android-sdk:4.18.0'
there is a problem with the latest version in Facebook sdk with Android sdk version 23.
