Multiple apk based on Flavours in Android Studio

Step 1. Create Android Studio Project

Step 2. Go to the build.gradle file in the app module then add Flavours in that file

productFlavors {

    demo {
        applicationIdSuffix ".demo"
        resValue "string", "app_name", "Demo App"
    }
    full {
        applicationIdSuffix ".full"
        resValue "string", "app_name", "Full App"    }
}

after changes sync gradle ,their will be option Build Variants their we can switch demo / full application build









 Full Source code of build.gradle




apply plugin: 'com.android.application'
android {
    compileSdkVersion 25   
    buildToolsVersion "25.0.2"
    defaultConfig {
//        applicationId "com.example.nithin.flavoursample"        
//       minSdkVersion 14        
//       targetSdkVersion 25   
//       versionCode 1  
//       versionName "1.0"
//        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
   }
    buildTypes {
        release {
            minifyEnabled false      
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'      
            }
    }


    productFlavors {

        demo {
            applicationIdSuffix ".demo"
            resValue "string", "app_name", "Demo App"
        }
        full {
            applicationIdSuffix ".full"
            resValue "string", "app_name", "Full App"        }
    }


}

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-v7:25.1.0'   
     compile 'com.android.support:design:25.1.0'    
     testCompile 'junit:junit:4.12'}

Step 3. Create folders (demo/full) under src

Step 4. Create java,res, manifest file folders
          before adding files change build variants option

full application (build variant - fullDebug)

demo application  (build variant - demoDebug)
