我保存照片,像这样:
File dcimDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
File picsDir = new File(dcimDir, "MyPics");
picsDir.mkdirs(); //make if not exist
File newFile = new File(picsDir, "image.png"));
OutputStream os;
try {
os = new FileOutputStream(newFile);
target.compress(CompressFormat.PNG, 100, os);
os.flush();
os.close();
b.recycle();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
然而,当我通过它在内部存储器窗口查找图像,画廊证实了这一点:
However, when I look for the image through windows it is in the internal memory, the gallery confirms this:
这最后一个是混乱的,它说,内部存储器,但后来也有 sdcard0
中的文件路径。
This last one is confusing, it says internal memory, but then also has sdcard0
in file path.
所以,当不对外并不意味着外部?它是一个设备设置的事,或/小姐认识 getExternalStoragePublicDirectory
So when does external not mean external? Is it a device set up thing, or an I miss-using/miss-understanding getExternalStoragePublicDirectory
?
推荐答案
在MTP发动机有时会报告 getExternalStorageDirectory()
为内部存储,这就是为什么它显示出来这个名字,当你安装设备作为Windows,Linux等的体积。
The MTP engine sometimes reports getExternalStorageDirectory()
as "Internal Storage", which is why it shows up under that name when you mount the device as a volume on Windows, Linux, etc.
外部存储始终意味着用户可以通过USB电缆的装置访问存储。在内部存储的标签可能是用在哪里外部存储板上(内部)闪存组成部分的设备。
External storage has always meant the storage that the user can access by means of a USB cable. The "Internal Storage" label is probably used on devices where external storage is part of the on-board ("internal") flash.
