compileSdkVersion，buildToolsVersion还有targetSdkVersion要一致，从而避免build的时候报错

Android Studio里的app的build.gradle文件：

 android {
     compileSdkVersion 24
     buildToolsVersion "24.0.0"

     defaultConfig {
         applicationId "com.wingsofts.rxretrofitmvpdagger2databinding"
         minSdkVersion 15
         targetSdkVersion 24
         versionCode 1
         versionName "1.0"
     }
     buildTypes {
         release {
             minifyEnabled false
             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
         }
     }
     dataBinding {
         enabled = true
     }
 }
