意图在Android 13上提供null

Question

由于Android 13，您需要使用意图过滤器和类别传递数据的意图。

我使用的是“Intent.PutIntegerArrayListExtra(”)方法，所以我就这样指定了过滤器。

[IntentFilter(new[] { Intent.ActionSend }, Categories = new[] {
    Intent.CategoryDefault })
]

但这不管用。所以我想我可能需要指定数据，但我不知道ArrayList需要哪个“ArrayList”。

更新：

问题：

第一项活动：

var intent = new Intent(this, typeof(ExampleActivity));
intent.PutIntegerArrayListExtra("Items", items.Select(x => (Java.Lang.Integer)x).ToList());

第二项活动：

var items= Intent.GetStringArrayListExtra("Items");

在Android 13上返回null。

解决办法/解决方案：

FirstActivity：

Bundle bundle = new Bundle();
var intent = new Intent(this, typeof(ExampleActivity));
List<Java.Lang.Integer> itemsArrayList = items.Select(x => (Java.Lang.Integer)x).ToList();
bundle.PutIntegerArrayList("Items", itemsArrayList);
intent.PutExtras(bundle);

SecondActivity：

Bundle bundle = Intent.Extras;
var items = bundle.GetIntegerArrayList("Items");

有太多的类型，所以我不能上传所有的。有关更多细节，请查看链接。https://github.com/khellang/MimeTypes/blob/master/src/MimeTypes/MimeTypes.cs.pp
