代号一个MediaPlayer在Android设备上不起作用

Question

i am creating a mediaplayer app which is supposed to stream mp3 files from remote url.the problem is that the everything works fine on the codename one simulator but not on an actual android device.I want the app to show native player controls like on the simulator.below is my code and screenshots

 try {
      video = MediaManager.createMedia(sample_url,true);
       Display.getInstance().callSerially(() -> {
                if (mp != null){
                    mp.getMedia().cleanup();
                }
                Image samp = theme.getImage("sample.png");
                Label samlabel = new Label();
                samlabel.setIcon(samp);
                mp = new MediaPlayer(video);
                mp.setAutoplay(false);
                video.setNativePlayerMode(true);
                sample.add(BorderLayout.CENTER,BorderLayout.centerAbsolute(samlabel));
                sample.add(BorderLayout.SOUTH,mp);
                 //songDetails.add(mp);

            });

the first image is the simulator screenshot and the second image is the actual android device screenshot

It's unclear from your post if this is an mp3 which is audio and doesn't have media control or an actual video. The MediaPlayer class is strictly for video and you passed true to indicate that this is a video file so I'll treat it as such.

Notice that if this is an audio file then you need to add/create your own controls and shouldn't use the MediaPlayer class.

We recently defined behaviors for native media control rendering as explained here .

Just use:

video.setVariable(Media.VARIABLE_NATIVE_CONTRLOLS_EMBEDDED, true);
