我在我的应用程序中使用 FragmentActivity 和几个片段。这些片段中的每一个都包含一个图像和一些带有动画的文本。当用户在屏幕上滑动时，片段会发生变化。

现在我已经为此工作了 10 天，并在具有不同 Android 版本的不同设备上测试了 FragmentActivity。从过去 10 天开始我一直坚持这一点的原因是我遇到了崩溃

Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 27830 (ple.myfragexample)

现在，仅当我特别在 Android 4.1.2 上测试 FragmentActivity 时才会出现此错误。它可以在 Android 2.3.3、4.0.3、4.0.4、4.2 甚至 2.2 上正常运行。错误日志如下：

我在互联网上进行了很多搜索并尝试了很多关于此的事情，但是，我的 Fragments 在任何其他版本的 Android 设备上的工作变得更加流畅，但仅限于 Android 4.1.2。我也尝试使用Universal Image Loader，但它仍然因致命信号 11 而崩溃。我使用 Universal Image Loader 时得到的错误日志如下：

现在，我知道这里也有很多关于致命信号 11 的问题，但我很担心和困惑，因为我只在 Android 4.1.2上而不是在任何其他 Android 版本上遇到这种崩溃。

我的问题现在解决了。我刚刚从我的图形团队重新调整了图像的大小。以前我使用的是 1280x768 分辨率的图像，但我将它们缩小到 800x480 并且崩溃消失了。感谢所有的建议。

另外，我认为 Jelly Bean (4.x) 增强了 UI，因此它比低版本的 Android 占用更多的内存来处理 UI 本身，这就是它无法管理处理（缩小）较大图像的原因.

看看我的问题：

Android 4.0.3 上画布上的奇怪崩溃绘图。A/libc：致命信号 11 (SIGSEGV)

也许这是同样的问题。当我尝试将少量数字用于笔画或其他Paint属性时，就会出现问题。

setStrokeWidth(0.007f);

从来没有解决，我建议缩放画布并使用更大的数字。
