android - 在更新数据和显示 dialogFragment 期间点击主页时崩溃。非法状态异常

Question

就我而言，在我的应用程序设置中，我点击更新数据库的按钮，它会显示带有进度的对话框 fragment ，如果我点击主页按钮 - 我的应用程序崩溃。

记录错误:

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
                                                                        at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1489)
                                                                        at android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1507)
                                                                        at android.support.v4.app.BackStackRecord.commitInternal(BackStackRecord.java:634)
                                                                        at android.support.v4.app.BackStackRecord.commit(BackStackRecord.java:613)
                                                                        at android.support.v4.app.DialogFragment.dismissInternal(DialogFragment.java:201)
                                                                        at android.support.v4.app.DialogFragment.dismiss(DialogFragment.java:167)
                                                                        at com.guardian.glass.ui.settings.SettingsActivity$6.onComplete(SettingsActivity.java:328)
                                                                        at com.guardian.glass.ui.DialogProgressFragment$1.onDataLoaded(DialogProgressFragment.java:63)

在我的类(class) SettingsActivity 方法的代码中弹出错误。

private void fetchDatabaseFromServer() {
        UserOperationsTask getCountriesTask = new UpdateCountries(new DialogProgressFragment() {
            @Override
            public void onComplete(boolean success) {
                dismiss(); // here i get error
                updateDatabaseSize();
                updateFilters();
                MeasureUtils.makeDefaultTemplate(SettingsActivity.this, true);
            }
        });
        getCountriesTask.execute(SettingsActivity.this);
        showProgress();
        updateDataBaseProfile();
    }

我的内心阶层

private class UpdateCountries extends UserOperationsTask {
        final DialogProgressFragment progressDialog;

        UpdateCountries(DialogProgressFragment progressDialog) {
            super(UserOperationsTask.TaskMode.MODE_LOAD_COUNTRIES, null);
            this.progressDialog = progressDialog;
        }

        @Override
        public void onLoadFinished(Bundle resultData) {
            setRegionLabels();
            updateFilters();
            hideProgress();
            String errorMessage = resultData.getString(UserOperationsTask.RESULT_ERROR_STRING);
            if (errorMessage != null) {
                Log.d(TAG, "getCountriesFromServer error: " + errorMessage);
                showMessage(getString(R.string.info_title), getString(R.string.server_request_error));
            } else {
                progressDialog.start(SettingsActivity.this, DialogProgressFragment.DialogMode.MODE_UPDATE);
                progressDialog.setCancelable(false);
                progressDialog.show(getSupportFragmentManager(), DialogProgressFragment.class.getSimpleName());
            }
        }
    }

请告诉我如何最好地解决这个问题？

多谢你们!我找到了解决方案 - 就我而言，相反

dismiss();

更好地使用

dismissAllowingStateLoss();
