我一直在研究一种解决方案，该解决方案涉及从代号一个应用程序捕获图像并将其存储在图库中，但根据我看到的图像是临时文件的文档，我需要一个代码将该文件复制到画廊，所以我可以随时得到它我想要的
到目前为止的代码:
String imageName = "Hello.png";
String filePath = Capture.capturePhoto();
if(filePath != null) {
try {
Util.copy(FileSystemStorage.getInstance().openInputStream(filePath), Storage.getInstance().createOutputStream(imageName));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
我需要注入(inject)替换 Storage.getInstance().createOutputStream(imageName)
画廊的完整路径
我发现有一个名为 CameraKit 的原生库:
我在 iOS 上尝试了演示 [在 iPhone 7 上尝试过]，当按下捕获图像时导致以下异常

问候，
这会将图像复制到您的本地存储中。您也可以将其复制到本地文件系统主目录，但不能将其复制到设备库中。
为此，您需要一个明确的 API 将图像文件存储在那里。一些相机和操作系统实现将图像存储在图库中，而另一些则不存储。不幸的是，这不是一般容易控制的东西。
关于android - 如何将捕获的图像保存到画廊代号一？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52354291/
