将uri存储在mysql数据库中的最佳方法

Question

I have an android app in which a user registers using his/her facebook account, and I want to get that user's profile picture, the method that the sdk offers returns the URI(i) for that profile picture, I want to send this uri to my php server and then store it in mysqldata base, and because I new to this I have a bunch of questions: What is the best way (field) to store the uri in my server database? I ll be doing in further steps some http request to download that picture, and the method I implemented to download a picture from a web server uses URLs, will I have issues in using the URI? Is there other issues that I ll have to be aware of in using URIs? Thank u in advance.

Answer 1

As has been commented, the best way is to store it is in its String form.

You can store the Uri using the toString method and when you get it back from your database later, you can use the Uri.parse(String) method to get it back into a Uri object.

To answer your other questions...

the method I implemented to download a picture from a web server uses URLs, will I have issues in using the URI?

This shouldn't be a problem as it's a fairly simple task to convert from a Uri to a URL.

Is there other issues that I ll have to be aware of in using URIs?

One thing to note is that Android has two types of Uri available in the SDK. The one in the android.net package (the one I referred to above) and also the one from the Java SDK . I would recommend you familiarise yourself with the available classes and decide which one is more suitable for your purposes.
