android - 当我在 android 4.1 中发送大小超过 20 的 HashMap 时，我崩溃了

Question

当我在 android 4.1 中发送大小超过 20 的 HashMap 时，我会崩溃并显示以下日志:

我为此做了什么:

Intent intent = new Intent(MyActions.PREVIEWS);
HashMap<String, Bitmap> thumbnails = new HashMap<String, Bitmap>();
// added more than 20 items
intent.putExtra("previews", thumbnails);
setResult(RESULT_OK, intent);
finish();

Answer 1

您应该将Bitmap 保存到文件中并将它们的引用传递给另一个 Activity 。 Extra 的 bundle 大小有限制:https://groups.google.com/forum/?fromgroups=#!topic/android-developers/kwmTGz8GAoQ

在 this 上回答问题也应该有帮助
