android - 如何(以及在​​哪里)修复 android.os.BadParcelableException : ClassNotFoundException when unmarshalling: RecyclerView$SavedState?

Question

我的 android 应用程序的生产 apk 中出现以下异常已有 1 天了:

以上所有崩溃报告均来自 Android 2.3.3 - 2.3.7 版本。不确定是什么原因造成的。

我也搜索了其他类似的帖子，但答案是围绕一个实现了 parcelable 的自定义对象，我没有在我的应用程序中实现它。

我在我的应用程序中使用最新版本的 android 支持库和播放服务，如下所示:

compile 'com.android.support:cardview-v7:23.1.1'
compile 'com.android.support:design:23.1.1'

compile 'com.google.android.gms:play-services-analytics:8.4.0'
compile 'com.google.android.gms:play-services-ads:8.4.0'
compile 'com.google.android.gms:play-services-appinvite:8.4.0'
compile 'com.google.android.gms:play-services-plus:8.4.0'

这是失败 Activity 的代码(我觉得相关，如果不合适请告诉我还需要什么):

private void initNavigationMenu() {
    mNavigationView = (NavigationView) findViewById(R.id.nav_view);
    mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem) {
            return onNavItemSelected(menuItem);
        }
    });

    Menu menu = mNavigationView.getMenu();

    MenuItem menuItem = menu.findItem(R.id.action_tutorial);
    IconDrawable iconDrawable = new IconDrawable(this, MaterialIcons.md_ondemand_video)
            .colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_settings);
    iconDrawable = new IconDrawable(this, MaterialIcons.md_settings).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_images_all);
    iconDrawable = new IconDrawable(this, EntypoIcons.entypo_images).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_images_screenshots);
    iconDrawable = new IconDrawable(this, MaterialIcons.md_camera).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_favorites);
    iconDrawable = new IconDrawable(this, MaterialIcons.md_favorite).colorRes(R.color.black);

    menuItem = menu.findItem(R.id.action_translate);
    iconDrawable = new IconDrawable(this, MaterialIcons.md_translate).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_feedback);
    iconDrawable = new IconDrawable(this, MaterialIcons.md_feedback).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_rate);

    menuItem = menu.findItem(R.id.action_invite);
    iconDrawable = new IconDrawable(this, MaterialIcons.md_insert_invitation).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_facebook);
    iconDrawable = new IconDrawable(this, FontAwesomeIcons.fa_facebook).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_twitter);
    iconDrawable = new IconDrawable(this, FontAwesomeIcons.fa_twitter).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_google_plus);
    iconDrawable = new IconDrawable(this, FontAwesomeIcons.fa_google_plus).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);

    menuItem = menu.findItem(R.id.action_remove_ads);
    iconDrawable = new IconDrawable(this, MaterialIcons.md_attach_money).colorRes(R.color.black);
    menuItem.setIcon(iconDrawable);
    menuItem.setVisible(!BuildConfig.IS_PRO);

    setHeaderView();
}

private void setHeaderView() {

    boolean initializePlusOneButton = false;
    GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
    int code = googleApiAvailability.isGooglePlayServicesAvailable(this);
    if (code == ConnectionResult.SUCCESS) {
        initializePlusOneButton = true;
    } else if (googleApiAvailability.isUserResolvableError(code)) {
        googleApiAvailability.showErrorDialogFragment(this, code, REQ_CODE_GOOGLE_API_ERROR);
    }

    View headerView = LayoutInflater.from(this).inflate(
            initializePlusOneButton ?
                    R.layout.activity_home_drawer_header :
                    R.layout.activity_home_drawer_header_wo_plus_button, null);
    if (initializePlusOneButton) {
        mPlusOneButton = (PlusOneButton) headerView.findViewById(R.id.plus_one_button);
    }

    mNavigationView.addHeaderView(headerView);

    gLogger.debug(String.format(
            "setHeaderView(): initialize plusOneButton=%s", initializePlusOneButton
    ));

无论哪个 View 给出错误，在该 View 的 xml 声明上使用 android:saveEnabled="false" 或 yourView.setSaveEnabled(false)以编程方式。这样您就可以避免保存该 View 的状态(当应用程序进程被终止时)并且在恢复时不会崩溃。
