android - Activity状态丢失，部分设备Illegal state异常

Question

我在我的 android 应用程序中使用 BottomBar 菜单。 BottomBar 中有 5 个菜单。这是主要 Activity

public class MainActivity extends BaseActivity {
    private static final String TAG = "MainActivity";
    private static final String COMMAND_RESET_PASSWORD = "reset-password";
    private static final String COMMAND_REFERRAL = "referral";
    private static final int HOME = 0;
    private static final int MAP = 1;
    private static final int DEAL = 2;
    private static final int NOTIFICATION = 3;
    private static final int SETTINGS = 4;
    private BottomBar mBottomBar;
    private int mCurrentTab = HOME;

在选项卡(底部栏菜单)之间切换会导致某些设备上的应用程序崩溃。但我无法重现异常。
这是堆栈跟踪

快速解决方案是对您为当前 Activity 执行的所有 FragmentTransactions 使用 .commitAllowingStateLoss(); 而不是 .commit();。
