调用Intent.getStringExtra（）定期抛出StackOverflowError

Question

我有一个Android应用程序，我支持并在多次调用其中一个活动之后，在尝试从intent中获取额外内容时抛出stackoverflowerror。这是从崩溃时的堆栈跟踪。任何想法为什么在下次调用活动至少4次之后抛出StackOverflowError时，从意图中获取额外内容？

用于建立意图的代码，并包含字符串，字符串，布尔值，对象：

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); 

和被投掷的StackOverflowError代码：
uri = getIntent().getStringExtra(AppNames.EXTRA_VIDEO_URI);

Answer 1

你对象看起来太复杂。当你序列化一个对象时，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，等等。

Answer 2

据我所知getIntent().getStringExtra()返回的字符串不是URI。
