MediaPlayer delays more than 20 seconds trying to open a non-existent url

My app uses MediaPlayer to play audio files from our CDN.
It's not the typical situation, but sometimes the file might not exist.
In that case, the CDN (AWS CloudFront-based) returns a 403 - Forbidden HTTP status code (please see attached response dump).
This seems to annoy MediaPlayer, and enters a loop of 10 delayed retries before triggering an error event. The problem is, the Java application does not have a clue on what's going on until the whole process ends.
I don't know if this is a bug in MediaPlayer, not handling the 403-Forbidden code as a fatal error, or this is done for a reason, as this happens at least in Android 5, 6 and 7, the ones I've tried.
Have you faced this problem? Is there any workaround? Should I file a bug to Android ?
in my app, this is what happens after calling prepareAsync() for a non-existent file:

note the above retries took 20 seconds, then the error is reported back to the app.

Android Camera API Error 100 only on back camera

I'm trying to capture an image from the back camera using the Android Camera API.
I'm using this code, 4. Tutorial: Using the camera API. It works when it uses the front camera. When I change CAMERA_FACING_FRONT to CAMERA_FACING_BACK, I get the Error 100 on
camera.takePicture(null, null, new PhotoHandler(getApplicationContext()));
I'm using Samsung Galaxy S3. Anyone knows how to solve this? It has been asked a multiple times, but I haven't found a real solution anywhere.
Edit: Full log until Error 100

cordova media plugin stopped working on Android 6

I have an application on Google Play that streams music from a radio station built with the latest cordova (5.4) and I am using some of the basic plugins such as:
device plugin
crosswalk webview plugin
dialogs plugin
...
files plugin
media plugin
On Android 5.0+ the streaming works fine but recently when I upgraded my nexus on android 6.0 the streaming stopped. I updated media and file plugin to the latest versions (2.0.0 and 4.0.0 respectively), as cordova stated in their blog that these versions support the new permission checking on Android 6 but still the streaming is not working. The log gives me this:

IPADDRESS:PORT is a real http://ipaddress:port URL stream which works fine.
I now it has to do with the permissions but still no luck on finding exactly what. Going on app-info and on new permissions menu I see that the app uses Microphone, Phone and Storage permissions which are all enabled. I searched a lot and couldn't be able to find something similar.
Any help is appreciated

I found the problem, just comment this line on AudioPlayer.java
public void onPrepared(MediaPlayer player) {
// Listen for playback completion
this.player.setOnCompletionListener(this);
// seek to any location received while not prepared
//this.seekToPlaying(this.seekOnPrepared);
// If start playing after prepared
if (!this.prepareOnly) {
this.player.start();
this.setState(STATE.MEDIA_RUNNING);
this.seekOnPrepared = 0; //reset only when played
} else {
this.setState(STATE.MEDIA_STARTING);
}
// Save off duration
this.duration = getDurationInSeconds();
// reset prepare only flag
this.prepareOnly = true;
// Send status notification to JavaScript
sendStatusChange(MEDIA_DURATION, null, this.duration);
}

Checked on Github in the official repo and found this
Tried on a new sample app and worked fine on my Android 6.0 device. The solution is close to what luckakashi suggested with some extra commenting.

Seems something wrong from Crosswalk, have you try if you remove the Crosswalk plugin? And is your Android 6.0 device 64-bit?

Android TV VideoView strange error code

Im coding an player application for Android Tv.
While testing to play videos on a nexus player device the VideoView (that is a wrapper of MediaPlayer) is giving me some strange error codes that are not documented at all in the api references.
My nexus player is api 23 (android M) and i also target api 23 in my app.
Here is the log:

Android audio-streaming issue on version 4.2

I am building an audio streaming app. Here is the code I use to launch the media player:
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("http://wunh.org:8000/"), "audio/*");
startActivity(intent);
The code works fine on my Droid phone (Android 2.3.4) - it brings up the phone media player and plays the station...
But it does not work on Nexus 7 (Android 4.2) - both "Google play music" and "Video player" fail with the same error code:
12-04 11:49:25.373: E/MediaPlayer(13331): Error (1,-1004)
