I have tried to write a service which will upload image from shared pref one by one :
Note : i hv hardcoded some of things here like image are from sdcard so path is hardcoded, images names are hardcoded, so plz change it appropriately and try out below code , i hv tested and worked for me
Below code contains Service, Activity[upload button, listview], xmlLayout, php service which will upload image on ftp.
Activity :
public class MainActivity extends Activity {
SharedPreferences sharedPref;
SharedPreferences.Editor editor;
ListView listview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sharedPref = getSharedPreferences("myfiles", MODE_PRIVATE);
editor = sharedPref.edit();
editor.putString("0", "monika_pin.png");
editor.putString("1", "monika_pin1.png");
editor.putString("2", "monika_pin2.png");
editor.commit();
String[] arr = new String[] { "/mnt/sdcard/monika_pin.png",
"/mnt/sdcard/monika_pin1.png", "/mnt/sdcard/monika_pin2.png" };
List<String> list = Arrays.asList(arr);
MyAdapter adapter = new MyAdapter(this, R.layout.listitem_imv, list);
listview = (ListView) findViewById(R.id.listView1);
listview.setAdapter(adapter);
}
class MyAdapter extends ArrayAdapter<String> {
List<String> mList;
LayoutInflater mInflater;
int mResource;
public MyAdapter(Context context, int resource, List<String> objects) {
super(context, resource, objects);
mResource = resource;
mInflater = getLayoutInflater();
mList = objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
if (convertView == null) {
view = mInflater.inflate(mResource, null);
} else {
view = convertView;
}
ImageView imageView = (ImageView) view
.findViewById(R.id.imageView1);
TextView textView = (TextView) view.findViewById(R.id.textView1);
imageView.setTag(mList.get(position));// tag of imageView == path to
// image
new LoadImage(imageView).execute();
textView.setText(mList.get(position).toString());
return view;
}
}
class LoadImage extends AsyncTask<Object, Void, Bitmap> {
private ImageView imv;
private String path;
public LoadImage(ImageView imv) {
this.imv = imv;
this.path = imv.getTag().toString();
}
@Override
protected Bitmap doInBackground(Object... params) {
Bitmap bitmap = null;
// File file = new File(
// Environment.getExternalStorageDirectory().getAbsolutePath() +
// path);
File file = new File(path);
if (file.exists()) {
bitmap = BitmapFactory.decodeFile(file.getAbsolutePath());
}
return bitmap;
}
@Override
protected void onPostExecute(Bitmap result) {
if (!imv.getTag().toString().equals(path)) {
/*
* The path is not same. This means that this image view is
* handled by some other async task. We don't do anything and
* return.
*/
return;
}
if (result != null && imv != null) {
imv.setVisibility(View.VISIBLE);
imv.setImageBitmap(result);
} else {

}
}
}

}

$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
Note : Above sure where u create this php file on ftp, create a folder also called upload where all files will be uploaded
