Andriod file Upload (ii) Android-side UI

Very simple UI. Click the button and select image upload (not the main thread) from the picture library.

The code for ANDRIOD main loadactivity is as follows:

public class Loadactivity extends Activity {public static final String tag_string= "loadactivity";p rivate string Pathstri ng=null;static final int flag_load=4;private Button button=null;private useruploadservice service=new    Useruploadserviceimpl ();        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);                Setcontentview (R.layout.activity_load);        button= (Button) This.findviewbyid (R.id.button1);                           Button.setonclicklistener (New View.onclicklistener () {@Overridepublic void OnClick (View v) {String status = Environment    . Getexternalstoragestate (); if (Status.equals (environment.media_mounted)) {//Determine if there is an SD card Intent intent=new Intent (Intent.action_pick, an         Droid.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);  Startactivityforresult (Intent, flag_load);    }}}); } @Override Public boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; Adds items to the action bar if it is present.        Getmenuinflater (). Inflate (r.menu.load, menu);    return true; } @Override protected void Onactivityresult (int requestcode, int resultcode, Intent data) {Super.onactivityr    Esult (Requestcode, ResultCode, data);    if (requestcode==flag_load) {if (data==null) {Toast.maketext (this, "You did not select any picture", Toast.length_long).

Setpositivebutton (" OK ", new Dialoginterface.onclicklistener () {@Overridepublic void OnClick (Dialogin Terface dialog, int which) {doupload ();}}               ). Create ().

Show ();//}//});}}). Start ();}}

<span style= "font-family:arial, Helvetica, Sans-serif;" >service.userupload (in, data,pathstring) </span>

An interface class implementation that handles the upload logic.
