    }
    
    compileSdkVersion 23
    buildToolsVersion "23.0.2"
    
    project.archivesBaseName = "LMS"; // HERE YOU NEED TO PROVIDE PROJECT NAME (BASE NAME)
    
    signingConfigs {
        release {
            keyAlias 'ALIAS_NAME'
            keyPassword 'ALIAS_PASWORD'
            storeFile file('C:/../../.android/KEYSTORE_NAME.keystore')
