3:      setContentView(R.layout.activity_main);  
4:      client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();  
5:      Button btn = (Button) findViewById(R.id.btnequal);  
6:      btn.setOnClickListener(new Button.OnClickListener(){  
7:        public void onClick(View v){  
8:          btnonClick();  
9:        }  
10:      });  
11:    }
