我在模拟器上开发并测试了一个应用程序，该应用程序的 API 为 4.1 (Jelly Bean)。当我在实际设备(三星 Galaxy Nexus)上调试应用程序时，它会在 logcat 中显示致命信号 11 (SIGSEGV) at 0x00000000 (code=1), thread 4395。您能帮忙吗？

最佳答案
如果您使用的是 4.1.2 或更高版本的 ics，您可以查看讨论的问题 here .
有人提到，最新版本的 Android 使用了一种不同类型的垃圾收集器，它以不同的方式处理大数据，从而导致致命信号。我在 Samsung Galaxy SIII 上遇到了同样的问题，并通过使用较小的图像解决了。您可以将较小尺寸的图像加载到启动屏幕中(我以为您正在开发一个 baground 图像应用程序或类似的东西)。
关于android - 致命信号11，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12575357/
