            int state = intent.getIntExtra("state", -1);
            switch (state) {
            case 0:
                Log.d(TAG, "Headset is unplugged");

                intent1.setData(uri);
                List<ResolveInfo> playerList ;
                playerList = pm.queryIntentActivities(intent1, 0);

                if( playerList != null){
                    for (int i = 0 ; i < playerList.size() ; i++){
                        //playerList.get(i).loadIcon(getPackageManager());
                        Log.v(TAG, playerList.size()+"");
                        Toast.makeText(MainActivity.this,playerList.get(i).loadLabel(pm)+":"+playerList.get(i).loadIcon(pm), Toast.LENGTH_SHORT).show();

                    }
                }

                break;
            default:
                Log.d(TAG, "I have no idea what the headset state is");
                Toast.makeText(MainActivity.this, "I have no idea what the headset state is", Toast.LENGTH_SHORT).show();
            }

Many applications don't support *both* audio and video. But you can create two lists and create the intersection of both: http://stackoverflow.com/questions/5283047/intersection-union-of-arraylists-in-java — zapl, Sep 25 '13 at 12:35

If you want to open an audio or video recording then this is the answer

 File filenew = new File(Environment.getExternalStorageDirectory(), "/Recording/"+filename);
               int file_size = Integer.parseInt(String.valueOf(filenew.length()/1024));
              // Toast.makeText(getApplicationContext(), ""+file_size, 10000).show();
               Intent intent = new Intent();  
              intent.setAction(android.content.Intent.ACTION_VIEW);  

              intent.setDataAndType(Uri.fromFile(filenew), "audio/*");  
              startActivity(intent);
