Question

整合facebook sdk与Android app.before整合应用程序工作正常，但一旦使用facebook应用程序意外停止在这里我放置code.suggest我如何解决这个

public class MainActivity extends Activity implements OnClickListener {

    Button btnTOLogin, btnTOPost, logOut;
    String APP_ID;
    Facebook fb;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        APP_ID = "308180782571605";
        fb = new Facebook(APP_ID);

        try {
            btnTOLogin = (Button) findViewById(R.id.button1);
            btnTOPost = (Button) findViewById(R.id.button2);
            logOut = (Button) findViewById(R.id.button3);
            btnTOLogin.setOnClickListener(this);
            btnTOPost.setOnClickListener(this);
            logOut.setOnClickListener(this);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

    }
