调用Intent.getStringExtra()会定期抛出StackOverflowError

标签: android android-intent stack-overflow

我有一个我支持的Android应用程序,在多次调用其中一个活动后,它会在尝试从intent中获取额外内容时抛出stackoverflower错误。这是崩溃时的堆栈跟踪。关于为什么在下次调用活动后至少4次抛出StackOverflowError从intent中获取额外内容的任何想法?

用于构建intent的代码包含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);  

抛出StackOverflowError的代码是:
uri = getIntent().getStringExtra(AppNames.EXTRA_VIDEO_URI);

你的对象看起来太复杂了。序列化Object时,必须序列化其内容。如果它包含其他对象,则必须对它们进行反序列化等等。

答案 1 :(得分:1)

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