Manually create your app directory in sd card and then save image in that directory.
You can try following snippet.
String root=Environment.getExternalStorageDirectory().toString();
File myDir = new File(root+"/demo_image");
if(!myDir.exists())
{
myDir.mkdir();
}
String fname = "Image"+String.valueOf(System.currentTimeMillis())+".jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
photo.compress(Bitmap.CompressFormat.JPEG,100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}

// TODO Auto-generated method stub
Intent i = new Intent(UploadActivity.this, ImagesForAds.class);

}
and it's worked fine, I can back data to my main activity as below :
b = getIntent().getExtras();
if (b != null) {
ImgData = b.getStringArrayList("IMAGE");
for (int i = 0; i < ImgData.size(); i++) {
map.add(ImgData.get(i).toString());
}
}
now it's ok... I need to upload those Images that I selected, here is my asyncTask:
public class ImageUploadTask extends AsyncTask<String, Void, String> {
String sResponse = null;
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
dialog = ProgressDialog.show(ImagesForAds.this, "Uploading",
"Please wait...", true);
dialog.show();
}
#Override
protected String doInBackground(String... params) {
try {
String url = "myLink";
int i = Integer.parseInt(params[0]);
Bitmap bitmap = decodeFile(map.get(i));
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
entity = new MultipartEntity();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);
byte[] data = bos.toByteArray();
//entity.addPart("user_id", new StringBody("199"));
//entity.addPart("club_id", new StringBody("10"));
entity.addPart("images", new ByteArrayBody(data,
"image/jpeg", params[1]));
Log.i(TAG, "array map: " + map.get(i));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost,
localContext);
sResponse = EntityUtils.getContentCharSet(response.getEntity());
System.out.println("sResponse : " + sResponse);
} catch (Exception e) {
if (dialog.isShowing())
dialog.dismiss();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
return sResponse;
}
#Override
protected void onPostExecute(String sResponse) {
try {
if (dialog.isShowing())
dialog.dismiss();
if (sResponse != null) {
Toast.makeText(getApplicationContext(),
sResponse + " Photo uploaded successfully",
Toast.LENGTH_SHORT).show();
count++;
if (count < map.size()) {
new ImageUploadTask().execute(count + "", "hm" + count
+ ".jpg");
}
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
}
}
and here how I invoke it :
int count = 0;
new ImageUploadTask().execute(count + "", "pk" + count + ".jpg");
The issue with AsyncTask.. it's upload only 1 image, how I can upload all images I have selected ?

This is your flaw :
if (count < map.size()) {
new ImageUploadTask().execute(count + "", "hm" + count
+ ".jpg");
}
not a good idea to create a new ImageUploadTask inside ImageUploadTask.
move your for loop inside doInBackground() and for updating user use publishProgress() and catch that event inside onProgressUpdate.

Get the item index of a listview and delete it on the listview and on my database

I hope anyone could help me on this. I really need a help right now. Thanks! :)

You can use this
sql_lite_db_obj.delete(tablename, whereClause, whereArgs)
For your convenience i edited my answer
public void clickHandler(View v) {
if (v.getId() == R.id.deleteOrder) {
int _id = 0;
try {
_id = (Integer) v.getTag(R.id.orderTitle);
} catch (Exception e) {
e.printStackTrace();
}
dh.delete(DatabaseHelpere.TableNAME, "_id=?",new String[] { String.valueOf(_id) });
}
}

adapter holder on listener cannot be final

I need to add a progress listener to each element of the horizontal list view, how can I do that?

How can I resolve the problem?

Something like this should be enough:
...
holder.image.setImageBitmap(item.getThumbnail(160, 160));
final ViewHolder finalHolder = holder;
item.setProgressListener(new ProgressListener() {
#Override
public void onProgress(int progress) {
finalHolder.progressUpdate.setProgress(item.getProgress());
}
});
finalHolder.progressUpdate.setProgress(item.getProgress());

Think that you can remove setProgressListener() from Upload class.
Instead add a ProgressBar variable and a method setProgressBar() to Upload.
In getView():
Upload upload = getItem(position )
upload.setProgressBar(holder.progressUpdate);
In Upload: in setProgress() you can now directly address the ProgressBar variable
this is the setProgress() that in your AsyncTask is called with mFile.setProgress(progress);
Instead of removing better out comment the function and the call.
Untested. Please test. This will not be much work.

Don't make holder final. It will not help you. You also made item final in order to use it in onProgress. But that will not do either. You have to determine the right holder with getTag() and if you put position in the holder (as int variable) then you can use holder.position to get the right item again with a getItem(holder.position)

Thanks for your responses all.

how to convert an class extends activity into independent class

I have a class that is currently extending Activity and I have methods like onCreate(),OnBackPress() etc. I want to turn it into an independent class but all the above methods become undefined. What is the problem? Shouldn't importing the classes be enough? For eg, I import android.view.View for findViewById but it still makes no difference. Please advise.

add image to sdcard folder in android

I want to develop an android application that can select multiple images and save them in a folder of sdcard. I could select multiple files but when i want to save them in sdcard folder there is only images name. I have understood it when i tried to show those images using GridView there are no images. Here is my code.....
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.image_selection);
Bundle b=getIntent().getExtras();
