我正在编写一个寻宝游戏类型的应用程序，该应用程序允许用户拍摄奖励位置的一两张照片，然后通过电子邮件提交这些图像。但是，我似乎无法将两个图像都放入电子邮件中，只能获取最新的图像。
我找到了这个答案：Cant send email with multiple attachment in android programmatically，这似乎表明我必须使用数组来执行此操作，但是那里的示例似乎与我正在执行的操作完全不匹配，因此我不确定如何制作数组。
下面是我当前的代码。有人可以告诉我如何将我的两个EXTRA_STREAMS放入必需的数组中（或者如果这不是正确的解决方法，请指向正确的方向）？

答案 0 :(得分：0)
您应该将Uri的所有文件放入var data = getComputedStyle($('span')[0]).background;
console.log(data);
，然后由Arraylist<Parcelable>放入意图
