java.lang.ClassCastException: java.lang.Object[] cannot be cast to pfe.essat.objet.com.Bts[]

I want to pass an array of objects without using the preference I use Intent!!! the Object class Bts

public class Bts implements Serializable {

                int idbts;
                String nombts;
                String ipaddress;
                String logb;
                String pawb;
                int xbts;
                int ybts;
                public  Bts(int idbts, String nombts, String ipaddress, String logb,
                                String pawb, int xbts, int ybts) {
                        super();
                        this.idbts = idbts;
                        this.nombts = nombts;
                        this.ipaddress = ipaddress;
                        this.logb = logb;
                        this.pawb = pawb;
                        this.xbts = xbts;
                        this.ybts = ybts;
                }
                //wthis setter and getter
}

the source activity Ps:JSONParseBts filled listeBts.

public class ApresConnextionActivity extends Activity {

    public Bts[] listeBts;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.setContentView(R.layout.apresconnect);
        final Button btsButton = (Button) findViewById(R.id.btbts);
        //boutonbts
        btsButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {               

              Log.w("myApp",""+listeBts.length);
                                Intent i = new Intent(ApresConnextionActivity.this, BtsBoutonActivity.class);
                                i.putExtra("tabbts",listeBts);
                                
                                startActivity(i);
                

            }
        });
         new JSONParseBts().execute();
    }

    public class JSONParseBts extends AsyncTask<String, String, JSONObject> { ... }

}

and distination Activity

public class BtsBoutonActivity extends Activity {
        cellule[] listecellule;
        Bts[] listeBts;
        int i,xx=0;

        protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                super.setContentView(R.layout.btsbouton);
                
                Bundle b = getIntent().getExtras();
                if (b != null)
                {
                        Bts[] listeBts = (Bts[])b.getSerializable("tabbts") ;
                        Log.w("myApp",""+listeBts.length);
                }else{
Log.w("myApp","you have problem");
}
                
        /*      Intent intent = getIntent();
                listeBts =  (Bts[])intent.getSerializableExtra("tabbts");*/
                
                 final Button[] b = new Button[listeBts.length];
                 LinearLayout ll3 = (LinearLayout)findViewById(R.id.linearLayout2); // Btn      
                 
                        for(i = 0; i < listeBts.length; i++){
                                //Log.w("myApp",listeBts[i].toString());
                b[i] = new Button(BtsBoutonActivity.this);
            b[i].setText(listeBts[i].getNombts());
             xx =listeBts[i].getIdbts();
            Log.w("myApp",""+xx);
            b[i].setId(xx);
            ll3.addView(b[i]);
            
            final Button btbts = (Button) findViewById(xx);
            btbts.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

        Toast saved_message=Toast.makeText(BtsBoutonActivity.this,btbts.getText()+"  "+btbts.getId(),1);
              saved_message.show();                        
              

              }});
            
                        }
        }

}

the erreur is:

05-10 16:29:25.096: E/AndroidRuntime(819): java.lang.RuntimeException: Unable to start activity ComponentInfo{http://ift.tt/1QwWvdL}: java.lang.ClassCastException: java.lang.Object[] cannot be cast to pfe.essat.objet.com.Bts[]
