Problems encountered:
1, in the Android when the choice is not on

     " div= "document.createelement (' 　　　　　　　Div '); "div.innerhtml=" result; "document.getElementById (' Picupload '). appendchild (Div); }}}< code>
      

Side can use the upload picture interface ...

Our original project useful Ajaxfileupload implementation, at the end should be no problem, if it is a native hybrid architecture, some models such as Millet is not supported.

PS: I seem to see the wrong topic, is to choose more pictures at the same time, I think it is more than one choice, the main ignore it.

Android does not support multi-image selection, this pit has been trampled before.
