git checkout master (or whatever branch you were on before you deleted .git)
git merge my_branch

string

public class Adapter_animal extends ArrayAdapter<String>  {
private final Activity context;
private final String[] animal;
private final int[] animal_id;
private MediaPlayer mp;


public Adapter_animal(Activity context, int mylist, String[] animal, int[] animal_id) {
    super(context, R.layout.mylist, animal);
    // TODO Auto-generated constructor stub
    this.context=context;
    this.animal = animal;

    this.animal_id = animal_id;
}

public View getView(final int position,View view,ViewGroup parent) {
    LayoutInflater inflater=context.getLayoutInflater();
    View rowView=inflater.inflate(R.layout.mylist, null,true);

    TextView txtTitle = (TextView) rowView.findViewById(R.id.titolo);
    txtTitle.setText(animal[position]);

    FloatingActionButton btn = (FloatingActionButton) rowView.findViewById(R.id.f1_btn);

    btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            stopPlaying();
            mp = MediaPlayer.create(Adapter_animal.this, animal_id);  //error in this line "cannot resolve method
            mp.start();
        }

    });











    return rowView;

};
private void stopPlaying() {
    if (mp != null) {
        mp.stop();
        mp.release();
        mp = null;
    }
}

You're passing an array to a method that expects a single resource id...

Documentation:

import os import shutil import fnmatch import stat import itertools def copyToDir(src, dst, updateonly=True, symlinks=True, ignore=None, forceupdate=None, dryrun=False): def copySymLink(srclink, destlink): if os.path.lexists(destlink): os.remove(destlink) os.symlink(os.readlink(srclink), destlink) try: st = os.lstat(srclink) mode = stat.S_IMODE(st.st_mode) os.lchmod(destlink, mode) except OSError: pass # lchmod not available fc = [] if not os.path.exists(dst) and not dryrun: os.makedirs(dst) shutil.copystat(src, dst) if ignore is not None: ignorepatterns = [os.path.join(src, *x.split('/')) for x in ignore] else: ignorepatterns = [] if forceupdate is not None: forceupdatepatterns = [os.path.join(src, *x.split('/')) for x in forceupdate] else: forceupdatepatterns = [] srclen = len(src) for root, dirs, files in os.walk(src): fullsrcfiles = [os.path.join(root, x) for x in files] t = root[srclen+1:] dstroot = os.path.join(dst, t) fulldstfiles = [os.path.join(dstroot, x) for x in files] excludefiles = list(itertools.chain.from_iterable([fnmatch.filter(fullsrcfiles, pattern) for pattern in ignorepatterns])) forceupdatefiles = list(itertools.chain.from_iterable([fnmatch.filter(fullsrcfiles, pattern) for pattern in forceupdatepatterns])) for directory in dirs: fullsrcdir = os.path.join(src, directory) fulldstdir = os.path.join(dstroot, directory) if os.path.islink(fullsrcdir): if symlinks and dryrun is False: copySymLink(fullsrcdir, fulldstdir) else: if not os.path.exists(directory) and dryrun is False: os.makedirs(os.path.join(dst, dir)) shutil.copystat(src, dst) for s,d in zip(fullsrcfiles, fulldstfiles): if s not in excludefiles: if updateonly: go = False if os.path.isfile(d): srcdate = os.stat(s).st_mtime dstdate = os.stat(d).st_mtime if srcdate > dstdate: go = True else: go = True if s in forceupdatefiles: go = True if go is True: fc.append(d) if not dryrun: if os.path.islink(s) and symlinks is True: copySymLink(s, d) else: shutil.copy2(s, d) else: fc.append(d) if not dryrun: if os.path.islink(s) and symlinks is True: copySymLink(s, d) else: shutil.copy2(s, d) return fc

Convenience method to create a public static MediaPlayer create (Context context, int resid) for a given resource id. On success, MediaPlayer will already have been called and must not be called again.

When done with the prepare(), you should call MediaPlayer, to free the resources. If not released, too many release() instances will result in an exception.

Note that since MediaPlayer is called automatically in this method, you cannot change the audio stream type (see prepare()), audio session ID (see setAudioStreamType(int)) or audio attributes (see setAudioSessionId(int) of the new setAudioAttributes(AudioAttributes).

Parameters

MediaPlayer - the context to use

Context - the raw resource id (resid) for the resource to use as the datasource

Returns

R.raw.<something> - a MediaPlayer object, or null if creation failed
