Question

我使用Eclipse编译应用程序，我曾经得到这个错误，但不是很多。但是因为我已经切换到android工作室，所以我遇到了很多崩溃。它几乎每台设备都崩溃了。我已经尝试过做一切但似乎无法解决这个问题。我尝试过使用getfragmentManager（）和getSupportFragmentManager（），两者都崩溃了。不知道现在该怎么办？

下面是我用来切换片段的代码。

private void showFragment(Fragment fragment){
fragmentManager = getFragmentManager();
fragmentTransaction = fragmentManager.beginTransaction();
if (!fragment.isAdded()) {
        fragmentTransaction.replace(R.id.home_frame, fragment).commitAllowingStateLoss();
        currentFragment = fragment;
    }
}

我的所有片段都扩展了一个基本片段，其中包含以下代码

private static final Field sChildFragmentManagerField;

static {
    Field f = null;
    try {
        f = Fragment.class.getDeclaredField("mChildFragmentManager");
        f.setAccessible(true);
    } catch (NoSuchFieldException e) {
        Log.wtf("LOGTAG", "Error getting mChildFragmentManager field", e);
    }
    sChildFragmentManagerField = f;
}

@Override
public void onDetach() {
    super.onDetach();

    if (sChildFragmentManagerField != null) {
        try {
            sChildFragmentManagerField.set(this, null);
        } catch (Exception e) {
            Log.e("LOGTAG", "Error setting mChildFragmentManager field", e);
        }
    }

}

请帮忙。我在商店里遇到了大量的崩溃和糟糕的评论。

下面是我的stacktrace
