Android MediaPlayer java.io.IOException: Prepare failed.: status=0x1

Question

I am using Android's MediaPlayer to set up a URL stream in my application. I have tried several different posts to deal with the exit code and error: (1, -2147483648).

I have attempted several different streams, but I can't seem to get the MediaPlayer to work. I have thought about moving over the Google's ExoPlayer but it is a little more complex and I don't want to jump ship in case I am missing something.

MediaPlayer:

private MediaPlayer player;
String url = "http://199.180.75.118:80/stream";     //temp stream
private void initializeMediaPlayer() {
    player = new MediaPlayer();
    player.setAudioAttributes( new AudioAttributes.Builder()
        .setUsage(AudioAttributes.USAGE_MEDIA)
        .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
        .build());

    try { 
        player.setDataSource(url);
        player.prepareAsync();
        player.setOnPreparedListener(new OnPreparedListener() {
            public void onPrepared(MediaPlayer mp) {
                mp.start();
            }
        });
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalStateException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } 
}

I have also included the android permission:

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

I have attempted to use the original stream type (but it throws a deprecated warning):

player.setAudioStreamType(AudioManager.STREAM_MUSIC);

So instead I used the .setAudioAttributes(...) I have attempted to just run prepare() instead of prepareAsync() which gave the title of the problem, but I still result in the same error. I have looked into the actual error definition with no luck either (Android MediaPlayer error (1, -2147483648)). I don't think it is a source issue since I have tried multiple other streams. Please let me know if I am skipping over something crucial that might be causing my error.

Edit If it helps at all, I have been looking into my calls and I found out that MediaPlayer is never calling onPrepared(...). I checked the Content-Types of all of the media I have been testing and they have all been audio/MPEG headers. So I don't understand why the MediaPlay isn't accessing the onPrepared.

private void initializeMediaPlayer() {
        player = new MediaPlayer();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            player.setAudioAttributes(new AudioAttributes.Builder()
                    .setUsage(AudioAttributes.USAGE_MEDIA)
                    .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                    .setLegacyStreamType(AudioManager.STREAM_MUSIC)
                    .build());
        } else {
            player.setAudioStreamType(AudioManager.STREAM_MUSIC);
        }
        try {
            player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    mp.start();
                }
            });
            player.setDataSource(url);
            player.prepareAsync();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

onPrepared calling in seconds.

In android 9, check this https://developer.android.com/training/articles/security-config

AndroidManifest.xml add networkSecurityConfig attributes

...
<application
android:networkSecurityConfig="@xml/network_security_config"
...>
...

in src/res/xml add network_security_config.xml file

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
            <certificates src="user" />
        </trust-anchors>
    </base-config>
</network-security-config>

try with this code Tested with real device Vivo V7+ Android 8.1.0

    private MediaPlayer player;
    String url = "http://199.180.75.118:80/stream";     //temp stream
    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    private void initializeMediaPlayer() {
        player = new MediaPlayer();
        player.setAudioAttributes( new AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_MEDIA)
                .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                .build());

        try {
            //change with setDataSource(Context,Uri);
            player.setDataSource(this, Uri.parse(url));
            player.prepareAsync();
            player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                public void onPrepared(MediaPlayer mp) {
                    //mp.start();
                    player.start();
                }
            });
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Make sure u defined the permission in manifest file

Manifest.xml

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

<Application
  android:usesCleartextTraffic="true"
  ....
  >
  //.....
  </Application>
