Android beginner need help on MediaPlayer - android

I am new to Android Dev but I am trying to get a video to run when the app first starts. I have the .mp4 file in a 'raw' folder under 'res' directory. I have this so far...
public class MainActivity extends Activity {
MediaPlayer videotime;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
videotime = MediaPlayer.create(this, R.raw.lessonslearned);
videotime.start();
}
protected void onResume() {
Log.e("Pickle", "onResume");
videotime = MediaPlayer.create(this, R.raw.lessonslearned);
videotime.start();
super.onResume();
}
Any help would be appreciated. The video should start when the app starts, play all the way through, then stop.
Thanks!
EDIT: I get MEDIAPLAYER error (1, -2147483648)
basically the video does not play and the audio is not in the background.

You shouldn't be calling videotime.start() in onCreate. That will start the MediaPlayer before the activity is in the forefront. You're calling videotime.start() twice. Only call it in the onResume() method.
You also need to call prepare on the MediaPlayer before starting it.
See here for an example of how to properly start a MediaPlayer:
Uri myUri = ....; // initialize Uri here
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(getApplicationContext(), myUri);
mediaPlayer.prepare();
mediaPlayer.start();
This should work the same for video, but with different options.

Definitely a better approach would be to use a VideoView. I´m not completely sure but if you want to play a video with a MediaPlayer you need a SurfaceView to see the video, I have used Phoenixblade9 solution but only with .mp3 files.
You can use a VideoView
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
VideoView v = (VideoView) findViewById(R.id.myVideoView);
v.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.video));
v.start();
}
just add the VideoView into your layout.
<VideoView
android:id="#+id/myVideoView"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
/>
Update: to play a Video in a MediaPlayer a SurfaceView is required.

"Can't play this video" Error using URL with VideoView and Mediacontroller

So I'm trying to do my homework, but the teacher's given me 0 information about this. There is an example of how to play a video from a file in the res/raw folder, but there's nothing about online URLs. Please help me, I just want a simple player. I'll attach a picture detailing exactly what is up. I'll also add the code, since it's not that much and I really have no clue what could be wrong. Error says this:
W/MediaPlayer: Couldn't open http://techslides.com/...
java.io.FileNotFoundException: No content provider: http://techslides.com/demos/sample-videos/small.mp4
And this is the code:
VideoView video;
String url = "http://techslides.com/demos/sample-videos/small.mp4";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
video = (VideoView) findViewById(R.id.videoView);
MediaController mc = new MediaController(this);
mc.setAnchorView(mc);
video.setVideoPath(url);
video.setMediaController(mc);
video.start();
}
I will finally add to this that I've tried several different URLs, including some https ones and some http.
EDIT:
So, I tried fixing it and it ended up looking like this:
video = (VideoView) findViewById(R.id.videoView);
final MediaController mc = new MediaController(this);
mc.setAnchorView(mc);
video.setVideoPath(url);
video.setMediaController(mc);
video.setOnPreparedListener(new MediaPlayer.OnPreparedListener(){
#Override
public void onPrepared(MediaPlayer mp){
video.start();
}
});
But it still gives me the same error when the emu is open. "Can't play this video". On the other hand, I got a bunch of new errors:
E/MediaPlayerNative: error (1, -2147483648)
E/MediaPlayer: Error (1,-2147483648)
D/VideoView: Error: 1,-2147483648
I'm not really familiarized with this technology, and the teacher hasn't given us any notions whatsoever as to what should or shouldn't be in the code for it to work. Just an example of a locally stored video playing in Android Studio with VideoView... that doesn't work when applied to online URLs.
So I've ended up fixing it myself. The problem wasn't in the code, for anyone wondering I've ended up using this simple format:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
video = (VideoView) findViewById(R.id.video);
Uri uri = Uri.parse("http://techslides.com/demos/sample-videos/small.mp4");
video.setMediaController(new MediaController(this));
video.setVideoURI(uri);
video.requestFocus();
video.start();
}
The problem was the AVD itself. I had a Pixel 1 running Android 9, and that for some reason didn't work. I've installed a Nexus 5 with Oreo and it works flawlessly.
This may help you
VideoView simpleVideoView = (VideoView) findViewById(R.id.simpleVideoView); // initiate a video view
// perform set on prepared listener event on video view
simpleVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
// do something when video is ready to play, you want to start playing video here
}
});
Try to start video only when its fully ready to play. Since mp4 will take some time to download.. so it might be in inconsistent state when you started video.
Hope this will help.

Playback video when back button was pressed

Hi All I have got a video set as a background in my app. When the app starts the video plays at the main menu and everything works great. Now when I select to go to next activity the video stop and the next activity starts and when the user is then finished with this activity and presses the back button to go to go to the main menu the video should play again, however it doesn't. Hope some one can help me with this. here is my code:
public class MainActivity extends Activity {
VideoView animation;
private MediaController mc;
MediaPlayer mp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mp = MediaPlayer.create(this, R.raw.leftbanktwo);
mp.setLooping(true);
VideoView animation = (VideoView) findViewById(R.id.imageAnimation);
Uri uri = Uri.parse("android.resource://" + getPackageName() + "/"+R.raw.cartoon);
mc = new MediaController(this);
animation.setMediaController(mc);
animation.requestFocus();
animation.setVideoURI(uri);
animation.start();
}
This is because your onCreate() method is not called again when user back to first Activity. If you want it to work like you described put the code which starts video in onResume() method.
Also, I would recommend to check out Activity Lifecycle.
Try This
#Override
protected void onResume() {
super.onResume();
if(mp!=null){
mp.reset();
mp.start();
}
}
#Override
protected void onPause() {
super.onPause();
if(mp!=null && mp.isPlaying()){
mp.pause();
}
}

Online mp4 video is not playing

what's the problem there, I have uploaded this video to server, but now its not playing, but its playing if i put this video on sdcard which is commented
public class VideoPlayerActivity extends Activity {
/** Called when the activity is first created. */
private MediaController mc;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
VideoView vd = (VideoView) findViewById(R.id.VideoView);
mc = new MediaController(this);
vd.setMediaController(mc);
Toast.makeText(this, "Video Player Started", 20).show();
//vd.setVideoPath("sdcard/video/abc.mp4");
vd.setVideoURI(Uri.parse("http://www.primesquad.com/future.mp4"));
vd.start();
}
}
streaming video differ from playing it from sdCard as you see in Android Supported Media Formats there is restrictions for streaming that don't apply when playing video.
I faced this problem with videos stream normally in HTC Desire but refuse to stream with Motorola droid

You have to call videoview.start() after this call only videoview will start playing video.

HTML5 Video Android VideoView

I am trying to play a video that is passed from a WebView in a VideoView. It works, except VideoView does not want to read it. I keep getting the error:
"Sorry, this video cannot be played."
Here is the code for the VideoView:
public class VideoHandler extends Activity {
WebView myWebView;
VideoView myVideoView;
WebChromeClient chromeClient;
WebViewClient wvClient;
Intent in;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video_player);
myVideoView = (VideoView) findViewById(R.id.videoview);
MediaController mediaController = new MediaController(this);
mediaController.setAnchorView(myVideoView);
String video = (MNWVMainPage.myWebView.getUrl());
myVideoView.setMediaController(mediaController);
myVideoView.setVideoPath(video);
myVideoView.start();
myVideoView.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.stop();
mp.release();
setContentView(R.layout.mnwv_main);
}
});
}
}
Why wont this load the video?
From just reading from your code, I can see no error.
Can you check a few things:
Does the video align to the format list here?
Have you open the camera/ another VideoView? Even if you release them, the buffer seems to need some time to be actually released.
