运行我的应用程序时，有50％的时间出现此错误
06-20 12:56:51.183: A/libc(32140): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 32140 (example.www)
我只需要重新打开该应用程序，然后它就可以工作了。但是我不知道为什么会收到此错误，导致应用程序崩溃。
我正在处理尺寸约为1200x1200px的大图像，并将其设置为背景。我还将该图像用作其他 Activity 作为背景的位图。还对服务器进行一些调用，并取回JSON数据。
希望我能提供足够的信息，因为我不知道要寻找什么...
我正在为4.1.2开发
完成Logcat

最佳答案
真正的错误是Out of memory on a 23818256-byte allocation。您正在尝试分配〜22MB的内存块，并且没有足够的可用内存，更不用说这么大的连续块了。
在这种情况下，它来自可绘制资源。大约22MB是一个真正的庞大图像，比1200x1200更像2400x2400。
您的进程堆大小为48MB，这是很大的，但是〜22MB几乎是堆预算的一半。
我建议您找出这是哪个可绘制资源(看起来可能是RelativeLayout的背景)，然后减小其大小和相似图像的大小。在这里，“大小”是指总像素数，而不是磁盘上的大小，因为重要的是RAM中的解压缩大小，而不是磁盘上的图像大小。
同样，这可能是资源目录的问题。例如，如果将1200x1200图像放在res/drawable/中，则实际上就是res/drawable-mdpi/的同义词。如果此设备恰好是-xhdpi设备，则可以解释内存使用情况，因为Android会尝试对该图像进行升采样并将每个尺寸加倍。
