我有一个我支持的Android应用程序，在多次调用活动之一后，尝试从意图中获取额外功能时会引发stackoverflowerror。这是崩溃时的堆栈跟踪。关于为什么在从活动中获取额外内容时，下次调用该活动至少4次之后为何抛出StackOverflowError的任何想法？
用于构建意图的代码为，其中包含String，String，boolean，Object：
Intent videoIntent = new Intent(this, VideoPlayer.class);
videoIntent.putExtra(AppNames.EXTRA_VIDEO_URI, uri);
videoIntent.putExtra(AppNames.EXTRA_VIDEO_TITLE, channel.getName());
videoIntent.putExtra(AppNames.EXTRA_VIDEO_MODE_RESUME, false);
videoIntent.putExtra(AppNames.EXTRA_MCD_CHANNEL, channel);
startActivity(videoIntent);
并且引发StackOverflowError的代码是：
uri = getIntent().getStringExtra(AppNames.EXTRA_VIDEO_URI);I/dalvikvm( 1719): Stack overflow, expanding (0x41048200 to 0x41048000)

最佳答案
您的对象看起来太复杂了。当序列化一个对象时，它的内容必须被序列化。如果它包含其他对象，则这些对象也必须反序列化，依此类推。
关于android - 调用Intent.getStringExtra()会定期引发StackOverflowError，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/2130517/
