Unable to stream Audio file through exoplayer in latest version Android

Question

I am using exoplayer to stream my Audio files from Firebase storage to my app. I used Media player earlier which was so slow. So I changed to exoplayer and its version was 2.8.4 at that time.

Here's the Code i used to stream Audio:

SimpleExoPlayer simpleExoPlayer;
private void SetupPlayer(){
    DefaultRenderersFactory renderersFactory = new DefaultRenderersFactory(this,
            null,DefaultRenderersFactory.EXTENSION_RENDERER_MODE_OFF);
    TrackSelector trackSelector = new DefaultTrackSelector();
    LoadControl loadControl = new DefaultLoadControl.Builder()
            .setAllocator(new DefaultAllocator(true, 16))
            .setBufferDurationsMs(MIN_BUFFER_DURATION,
                    MAX_BUFFER_DURATION,
                    MIN_PLAYBACK_START_BUFFER,
                    MIN_PLAYBACK_RESUME_BUFFER)
            .setTargetBufferBytes(-1)
            .setPrioritizeTimeOverSizeThresholds(true).createDefaultLoadControl();
    simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(renderersFactory,trackSelector,loadControl);
    String userAgent = Util.getUserAgent(this, "Play Audio");
    ExtractorMediaSource mediaSource = new ExtractorMediaSource(Uri.parse(audio_url),new DefaultDataSourceFactory(this, userAgent),
            new DefaultExtractorsFactory(),null,null);

    simpleExoPlayer.prepare(mediaSource);
}

It worked great. But now exoplayer has updated its version to 2.11.8 . In this version, ExtractorMediaSource , DefaultRenderersFactory , DefaultTrackSelector , ExoPlayerFactory are deprecated.

So I changed my code for the recent version.

Here's the Code:

    SimpleExoPlayer simpleExoPlayer;
    private void SetupPlayer(){
       // Create a data source factory.
        DataSource.Factory dataSourceFactory =
                new DefaultHttpDataSourceFactory(Util.getUserAgent(this
                        , "app-name"));
// Create a progressive media source pointing to a stream uri.
        MediaSource mediaSource = new ProgressiveMediaSource.Factory(dataSourceFactory)
                .createMediaSource(Uri.parse(audio_url));
// Create a player instance.
        simpleExoPlayer =  new SimpleExoPlayer.Builder(this).build();
// Prepare the player with the media source.
        simpleExoPlayer.prepare(mediaSource);
    }

Now it is showing error

java.lang.NoSuchMethodError: No static method metafactory(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite; in class Ljava/lang/invoke/LambdaMetafactory; or its super classes (declaration of 'java.lang.invoke.LambdaMetafactory' appears in /apex/com.android.runtime/javalib/core-oj.jar)

I searched Stack overflow . But everyone answers are deprecated ones. So I don't know how to fix it. Please help me with some solutions.

Found the Answer. I just missed adding compile options in build gradle. After Adding, it worked.

compileOptions {
        targetCompatibility JavaVersion.VERSION_1_8
    }
