   buildToolsVersion "29.0.2"

defaultConfig {
    applicationId "com.example.nibotransporti"
    minSdkVersion 21
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
 }
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

}
dataBinding.enabled = true
compileOptions {
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
};

}
