在给定的字符串代码中是什么意思.External_Conten_URI

Question

我想在android中从Gallery中选择一个图像，但我无法理解给定String中EXTERNAL_CONTENT_URI的用途。 请为我详细说明，我不太了解android。

android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI

Answer 1

EXTERNAL_CONTENT_URI will return images that are located in the "primary" external storage, while INTERNAL_CONTENT_URI will return images from the primary internal storage.

Both of these are not directly related to memory, they do not point to internal and external memory.

internal storage is the storage your app is allowed to use, other programs can not access this storage.

external storage is the storage that everyone can access and use.

Hope that helps.
