                case REQUEST_CODE_FILE:
                    ArrayList<EssFile> essFileList = data.getParcelableArrayListExtra(Const.EXTRA_RESULT_SELECTION);

主要是这个Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean androidx.fragment.app.FragmentManager.isDestroyed()' on a null object reference，在com.maple.filepickerlibrary.activity.SelectFileByScanActivity.onDestroy(SelectFileByScanActivity.java:123)

initUi方法里用了FragmentManager

List<Fragment> fragmentList = new ArrayList<>();
        for (int i = 0; i < SelectOptions.getInstance().getFileTypes().length; i++) {
            fragmentList.add(FileTypeListFragment.newInstance(SelectOptions.getInstance().getFileTypes()[i], SelectOptions.getInstance().isSingle, SelectOptions.getInstance().maxCount, SelectOptions.getInstance().getSortType(), EssMimeTypeCollection.LOADER_ID + i));
        }
        FragmentPagerAdapter adapter = new FragmentPagerAdapter(getSupportFragmentManager(), fragmentList, Arrays.asList(SelectOptions.getInstance().getFileTypes()));

能否看下什么问题，谢谢您
