Android 应用程序在四个特定活动上崩溃

Question

我在四项具体活动的意图方面遇到了一些问题。它随机崩溃，我不明白为什么会这样。它发生在四个活动上，我认为这与活动没有正确接收意图有关。我使用了一个 diff-checker 来验证这段代码和没有崩溃的活动之间没有什么不同，并且没有发现任何差异。更有趣的是，它似乎重新启动了在崩溃之前的活动，并在该活动之后正常继续而没有崩溃，但随后在这四个活动中的另一个上崩溃。

这是我的 Logcat：

08-09 16:16:39.031      384-399/system_process I/Choreographer﹕ Skipped 75 frames!  The        application may be doing too much work on its main thread.

如果我需要发布更多代码/logcat 读数，请告诉我。我是这方面的新手，所以请尽可能彻底地解释你的答案。

谢谢。

看起来您在主线程上做的太多并加载了一个非常大的图像（在主线程上不好）。该图像导致您的 VM 堆内存不足： 08-15 20:08:05.380 1547-1547/tk.emposoft.wirewizard E/dalvikvm-heap﹕ Out of memory on a 106990144-byte allocation.

您需要在读取图像时对其进行缩放，并在后台线程上进行加载。
