Android Combat Simple Tutorial-the 28th gun (based on bmob to achieve Avatar image settings and network upload Function!) ）

In the previous article, we introduced how to convert a URI into a string, and this article uses the method of the previous passage. Below we describe how to set the avatar after the image upload to the cloud method, this article based on the services provided by Bmob.

Take a look at the code: (The layout file is still the same as the first two articles, no longer available)

JavaBean class:

Package Com.example.userphoto;import Cn.bmob.v3.bmobobject;import Cn.bmob.v3.datatype.bmobfile;public class person Extends Bmobobject {private bmobfile icon;public bmobfile GetIcon () {return icon;} public void SetIcon (bmobfile icon) {This.icon = icon;}}

Execute the instance, and again the failure occurs:

Or a permissions issue:

And then do it again:

Prompt image upload successful. Let's look backstage:

OK, the picture has been uploaded successfully! Isn't it very hanging?

Welcome to reprint, Exchange, praise, attention!

Your support is my power!!!
