1.Gradle

implementation 'com.google.android.exoplayer:exoplayer:2.9.1'

이걸 하니까 

implementation 'com.android.support:appcompat-v7:27.1.1'

이 부분에서 에러가 났는데 버전을 똑같이 27.1.1로 바꿔주니까 된다.

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

이 부분을 꼭 넣어줘야 한다.

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.lipnus.exoplayer"
        minSdkVersion 19
        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'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

요 자리에 넣으면 된다.

2.Permission

<uses-permission android:name="android.permission.INTERNET" />

3.XML

<com.google.android.exoplayer2.ui.SimpleExoPlayerView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/exo_player_view">

</com.google.android.exoplayer2.ui.SimpleExoPlayerView>

simpleExoPlayerView는 deprecated되어있다. 일단 예제에 나온대로 구현.

4.MainActivity.kt

class MainActivity : AppCompatActivity() {

    private lateinit var exoPlayer: SimpleExoPlayer

    private var videoURL: String = "http://blueappsoftware.in/layout_design_android_blog.mp4"

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        try{
            var bandwidthMeter: BandwidthMeter = DefaultBandwidthMeter()
            var trackSelector: TrackSelector = DefaultTrackSelector(AdaptiveTrackSelection.Factory(bandwidthMeter))
            exoPlayer= ExoPlayerFactory.newSimpleInstance(this, trackSelector)

            val videoURI = Uri.parse(videoURL)

            val dataSourceFactory = DefaultHttpDataSourceFactory("exoplayer_video")
            val extractorsFactory = DefaultExtractorsFactory()
            val mediaSource = ExtractorMediaSource(videoURI, dataSourceFactory, extractorsFactory, null, null)

            exo_player_view.setPlayer(exoPlayer)
            exoPlayer.prepare(mediaSource)
            exoPlayer.setPlayWhenReady(true)
        }catch (e:Exception){
            Log.e("MainAcvtivity"," exoplayer error "+ e.toString());
        }


    }
}
