无法在OnSaveInstanceState-Android之后执行此操作

我有一个授权应用程序。在该应用程序中,用户有 accessToken 和 refreshToken . 我做了类似这样的事情,如果用户登录其他硬件而不是真正的硬件,他会自动注销。假设我有我登录的电话1。现在我正在登录phone2。当我授权我的令牌更改时。因此,如果令牌被更改而不是自动注销,我会签入phone1。但有时候在注销之后我会出现这样的错误 例外情况:

java.lang.illegalStateException:之后无法执行此操作 OnSaveInstanceState。

这是我在令牌过期时注销的地方。 注意这是一个

Call<RefreshTokenActivation> newToken = apiClient.newToken(supportObjToken);
        newToken.enqueue(new Callback<RefreshTokenActivation>() {
            @Override
            public void onResponse(Call<RefreshTokenActivation> call, Response<RefreshTokenActivation> response) {
                if (response.isSuccessful()) {

            } else {
                if (response.code() == 401) {

                    //Perform this call if refresh token is expired

                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            Activity activity = (Activity) context;
                            MainActivity mainActivity = (MainActivity) activity;
                            mainActivity.logOut();
                        }
                    }, 1000);
                }
            }
        }

如果响应为401,则意味着我的令牌已过期。如果令牌已过期,则在第二秒钟后,我将用户 mainActivity .

以下是MainActivity中的代码:

public class MainActivity extends AppCompatActivity
    implements FragmentChangeListener, TabLayoutLocationInterface {
private ConnectionDetector connectionDetector;
private SlidePageTabsMainFragment slidePageTabsMainFragment;
private MainFragment mainFragment;
private RelativeLayout logOut;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    SharedPreferencesManager.init(this);

    setContentView(R.layout.activity_main);

    logOut = (RelativeLayout) findViewById(R.id.list6);
    connectionDetector = new ConnectionDetector(this);
    slidePageTabsMainFragment = new SlidePageTabsMainFragment();
    mainFragment = new MainFragment();

    connectionEnable();
    userLogOut();
}

public void connectionEnable() {
    if (!connectionDetector.isConnected()) {
        Toast.makeText(this, "Please check your Internet", Toast.LENGTH_LONG).show();
    } else {
        Boolean loggedIn = SharedPreferencesManager.getInstance().getUserLogged();
        if (loggedIn) {
            this.replaceFragment(slidePageTabsMainFragment, true);
        } else {
            this.replaceFragment(mainFragment, true);
        }
    }
}

@Override
public void replaceFragment(BaseFragment fragment, Boolean isAddToBackStack) {
    String backStateName = fragment.getFragmentName();
    FragmentManager manager = getSupportFragmentManager();

    FragmentTransaction transaction = manager.beginTransaction();
    transaction.replace(R.id.main_fragment_container, fragment, backStateName);
    transaction.addToBackStack(backStateName);
    transaction.commit();
}

@Override
public int getTabLayoutLocation() {
    SlidePageTabsMainFragment slidePageTabsMainFragment = (SlidePageTabsMainFragment)
            getSupportFragmentManager().findFragmentByTag("SlidePageTabsMainFragment");
    if (slidePageTabsMainFragment == null) {
        return 0;
    }
    return slidePageTabsMainFragment.getTabLayoutLocation();
}

//If user click logOut button
public void userLogOut() {
    logOut.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            SharedPreferencesManager.getInstance().setUserLogin(false);
            SharedPreferencesManager.getInstance().removeUser();
            getSupportFragmentManager().popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
            replaceFragment(mainFragment, false);
        }
    });
}


//A function for automatic logOut
public void logOut() {
    SharedPreferencesManager.getInstance().setUserLogin(false);
    replaceFragment(new MainFragment(), false);
    getSupportFragmentManager().popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
    recreate();
    SharedPreferencesManager.getInstance().removeUser();
}

@Override
protected void onResume() {
    super.onResume();
    Log.d("Test", "Text");
}

}

我认为没有什么困难。所以我得到了这个例外 transaction.commit(); 排队 replaceFragment() 方法 MainActivity . 在那个电话里,你看,我在打电话 mainActivity.logOut(); 你看到了 主要活动 这个 logOut 功能。

//A function for automatic logOut
public void logOut() {
    SharedPreferencesManager.getInstance().setUserLogin(false);
    replaceFragment(new MainFragment(), false);
    getSupportFragmentManager().popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
    recreate();
}

所以在这个方法中,我改变了 SharedPreferences 值(在应用程序打开时检查是否需要用户登录?)在那之后,我要把碎片换成 mainFragment (这是基本片段,是的,我正在处理片段)。之后,我弹出所有碎片,因为注销后,如果我单击后退按钮,它将返回,所以弹出后,我重新创建应用程序。重新创建后,感觉像是应用程序第一次打开。好吧,那为什么它会抛出这样的异常呢?知道吗?
