In my activity I am setting all the Views like ImageView, TextViews with theirs respective data using AsyncTask.
after asyncTask.Execute();
I have a textView.onCLickListener which calls Camera and after the picture is taken, the ImageView in the activity is set to this pic.
But the problem is my asyncTask is called again after the onActivityResult();
Here is my complete Activity code:
public class UserProfileActivity extends Activity {
//many instance fiels here
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_profile);
new LongOperation().execute("");
userImage = (ImageView) findViewById(R.id.profileImage);
userName = (TextView) findViewById(R.id.userName_profile);
userLocation = (TextView) findViewById(R.id.userLocation_profile);
editInfo = (TextView) findViewById(R.id.edit_profile);
changeImage = (TextView) findViewById(R.id.changeImage_profile);
userScore = (TextView) findViewById(R.id.userScore_profile);
friendsLabel = (TextView) findViewById(R.id.userFriends_profile);
changeImage.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
//Point 1
}
});
//Point 2
}
private class LongOperation extends AsyncTask<String, Void, String> {
private InputStream is;
private StringBuilder sb;
private String result;
private ProgressDialog dialog = new ProgressDialog(context);
@Override
protected String doInBackground(String... params) {
//Point 3
try {
HttpResponse response;
HttpPost httppost = new HttpPost(
"http://www.xxxxx.com/yyyy/zzzz");
//httpclient is global to maintain sessions
response = SignUpActivity.httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "iso-8859-1"), 8);
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line = "0";
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
} catch (Exception e) {
Log.e("error in reading input stream", e.toString());
}
try {
JSONObject jObj = new JSONObject(result);
String status = jObj.getString("status");
score = jObj.getInt("credits");
level = jObj.getInt("level");
image = jObj.getString("image");
fname = jObj.getString("fname");
lname = jObj.getString("lname");
city = jObj.getString("city");
email = jObj.getString("email");
clickedUserId = jObj.getInt("user_id");
JSONArray friendsJsonArray = jObj.getJSONArray("friends");
size = friendsJsonArray.length();
ArrayList<String> friendsNames = new ArrayList<String>();
friendsIds = new int[size];
for (int i = 0; i < size; i++) {
friendsNames.add(friendsJsonArray.getJSONObject(i)
.getString("name"));
friendsIds[i] = friendsJsonArray.getJSONObject(i)
.getInt("user_id");
}
adapter = new ArrayAdapter<String>(context,
R.layout.simple_listview_item, friendsNames);
} catch (Exception e) {
Log.d("error in creating json object", e.toString());
}
} catch (Exception e) {
//Point 5
Log.e("error main try", "Error in http connection" + e.toString());
}
return "Executed";
}
@Override
protected void onPostExecute(String result) {
friendsList.setAdapter(adapter);
userScore.setText(score + " points" + " level " + level);
userName.setText(fname + " " + lname);
userLocation.setText(city);
changeImage.setText("Change image");
editInfo.setText("Edit");
friendsLabel.setText("Friends");
Bitmap bitmap = null;
try {
bitmap = BitmapFactory
.decodeStream((InputStream) new URL(image).getContent());
userImage.setImageBitmap(bitmap);
} catch (MalformedURLException e1) {
e1.printStackTrace();
userImage.setImageResource(R.drawable.xxx);
} catch (IOException e2) {
e2.printStackTrace();
userImage.setImageResource(R.drawable.xxx);
}
if (dialog.isShowing()) {
dialog.dismiss();
}
}
@Override
protected void onPreExecute() {
this.dialog.setMessage("Please wait");
this.dialog.show();
}
@Override
protected void onProgressUpdate(Void... values) {
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//Point 4
if (resultCode == RESULT_OK) {
if (data != null) {
photo = (Bitmap) data.getExtras().get("data");
userImage.setImageBitmap(photo);
}else{
Intent intent = new Intent(UserProfileActivity.this,

startActivity(intent);
}
} else {
