我有一个 ViewPager 活动，我用它来浏览包含“随机”网页的片段 Web 内容不受我控制。我正在使用 FragmentStatePagerAdapter 和最新的支持库。每个 Fragment 的布局都包含一个加载“随机”页面的 web 视图。用户可以无限期地向前翻转。

当我打开硬件加速时，在几次滑动后我会遇到段错误崩溃（转储在下面）。关闭 Activity 的硬件加速后，不会发生崩溃，但当然 webview 滚动和视图寻呼机转换非常不稳定。另外，我无法在 youtube 等页面上播放嵌入的视频。

崩溃不会发生在特定页面上。重现崩溃所需的滑动次数也各不相同 - 有时是第一次滑动，有时需要几次，但它非常一致。我在运行应用程序时检查了内存使用情况，它看起来很好（ram 和 vram） - 很好，因为我认为我没有使用太多，而且我没有收到任何低内存警告。

到目前为止，我已经在我尝试过的所有 3.0+ 设备上遇到了这个问题：

  • 东芝regza运行4.0.3
  • 摩托罗拉xoon运行3.2.1
  • 运行 4.0.4 的 Galaxy nexus 手机（fwiw，在手机上发生的频率较低）

这是一个已知的问题？任何解决方法？

好的，我找到了解决方法和崩溃的“原因”。我将“原因”放在引号中，因为我认为我在原始代码中没有做错任何事情。

我的片段中有以下代码：

@Override
public void onCreate(Bundle savedInstanceState)
{
    ...
    setHasOptionsMenu(true);
    ...
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
    inflater.inflate(R.menu.options_menu, menu);
}

@Override
public void onPrepareOptionsMenu(Menu menu)
{
    ... // apply a menu strategy that enables/disables some items based on app state
}

出于某种原因，如果我取出通货膨胀代码，则不再发生崩溃。解决方法是在活动级别膨胀菜单，然后仍然在片段级别应用菜单策略。不知道为什么会这样。如果它有所作为，我目前没有使用 ABSherlock。
