android客戶端閃退

老師，我把客戶端的代碼放在android程序里，給一個(gè)button監(jiān)聽事件，就是調(diào)用這個(gè)socket方法，但是一點(diǎn)button就閃退了，沒連接上~

protected?void?onCreate(Bundle?savedInstanceState)?{
??super.onCreate(savedInstanceState);
??setContentView(R.layout.activity_client);
??btn=(Button)?findViewById(R.id.button2);
??btn.setOnClickListener(new?OnClickListener()?{
???
???@Override
???public?void?onClick(View?v)?{
???
????initClientSocket();
???}
??});
?}
?@Override
?public?boolean?onCreateOptionsMenu(Menu?menu)?{
??
??//?Inflate?the?menu;?this?adds?items?to?the?action?bar?if?it?is?present.
??getMenuInflater().inflate(R.menu.client,?menu);
??return?true;
?}
?@Override
