    int reconnectInterval = 1000;
    int i;

    public boolean reconnect(String URL){
        Thread timer = new Thread(){
            public void run(){
                    for(i=1;i<6;i++){
                        if(APP.testConnection(APP.defaultUrl()) == 0){
                            status = false;
                        }else if(APP.testConnection(APP.defaultUrl()) == 1){
                            status = true;
                        }
                        try {
                            sleep(reconnectInterval * i);
                        } catch (InterruptedException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                    }

        return status;
    }

You create a new thread, which sleeps for a while, but the method which spawned it (reconnect) will return immediately. You should be using a Handler with postDelayed().

Take a look at the answer here:

Sleep is used too often. The correct design is to implement a listener for when a connection is available and respond to listener callback in your UI.
