android – OnCreate方法不断重复调用

更新：感谢大家试图帮助我解决这个bug.我仍然不确定事情,我能够回滚到以前的承诺,并从那里继续发展.这个以前的提交确实显示了同样的错误,但是在我注释掉了button.performClick()之后,它已经消失了.奇怪的是,这并不适用于最近的提交.

我仍然不明白这个错误,并希望能帮助确定根本原因.我最大的恐惧是不经意地重新介绍它.

我曾经见过最疯狂的错误.

OnCreate方法被一再调用,冻结了我的应用程序,并给了我轻微的闪烁.然后,唯一的解决方案是退出到主屏幕,强制从设置菜单退出应用程序.

这是正在发生的细节：

>申请开始(主要活动)
>主要活动调用第二个活动
> Second Activity调用onCreate,设置正常
>第二个活动随机决定退出创建 – 我认为这是发生了什么
> Second Activity的onCreate再次被调用.它不会回到主要活动.

我运行了@L_262_16@调试器,看来第二个活动成功完成了onComplete / onResume序列,然后决定退出并重启.

有没有人听说过这个行为？

我没有注意到抛出任何异常.此外,在调试过程中,我确实已经进行了检查,您所看到的那些位置是无声的. (这是较早的代码,然后我用print语句)

更新：当尝试停止该过程时,我必须打开飞行模式.这意味着它与这个代码块有关(Second Activity)

else if (Network.haveNetworkConnection(Login.getContext()) && Login.checkClientId())
        {...}

没有互联网,它将打到else语句,不显示此行为.

码：

主要活动的onResume(),我称之为第二个活动：

@Override
    public void onResume()
    {
        super.onResume();

        //check If logged in,else go to login page
        Login.setContext(getApplicationContext());

        //Reset Notification number
        GCMIntentservice.cancelNotifications();

        /** GO TO LOGIN **/
        if(!Login.isLoggedIn())
        {
            //If user is not logged in,open login page
            System.out.println("RESUMING MAIN AND STARTinG LOGIN INTENT");
            Intent intent = new Intent(Activitymain.this,ActivityLogin.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK|Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);

        } else
        {
            Login.setupstuffOnce();
            Event.pullEvents(); //Get New Events

            //update ListView
            updateMainFeed();
        }


    }

这是第二个活动：

public class ActivityLogin extends Activity
{

    private String postData;
    //private Context c;
    //final Timer timer = new Timer();

    //Facebook stuff
    private Facebook facebook = new Facebook(Config.FBAPPID);

    EditText username,password;
    Button loginButton,signupButton;

    @Override
    public void onCreate(Bundle savedInstanceStatE)
    {
        super.onCreate(savedInstanceStatE);
        // Open Database
        Login.setContext(getApplicationContext());
        Database.open(getApplicationContext());
    }

            Transfer.password = null;
            Transfer.username = null;
            loginButton.performClick();
        }

    }

    public void init()
    {

        Login.getUserLoggedIn();
        if (Login.isLoggedIn())
        {
            //Do Any Additional Setup
            Login.setupstuffOnce();

            // If user is logged in,open main
            Intent intent = new Intent(ActivityLogin.this,Activitymain.class);
