so I am making an app, I am just beginner, but I am stuck, I have this code:
public class MenuChoice extends Activity {
InputStream string = null;
ArrayList<String> Deals = null;
ArrayList<String> ImageBase;
int currentDeal = 0;
public void StreamReader() throws IOException{
InputStreamReader is = new InputStreamReader(string);
StringBuilder sb=new StringBuilder();
BufferedReader br = new BufferedReader(is);
String read = br.readLine();
while(read != null) {
//System.out.println(read);
sb.append(read);
read =br.readLine();
}
String[] DealList = sb.toString().split("±");
//ArrayList<String> deals = new ArrayList<String>();
for(int i = 0; i < DealList.length; i++){
Log.d("msgs", DealList[i]);
if(DealList[i].length() > 5){
Deals.add(DealList[i]);
}
}
// return deals;
}
public String DownloadImg(String urla, String newname){
String fileName = null;
try{
URL url = new URL (urla);
InputStream input = url.openStream();
try {
//The sdcard directory e.g. '/sdcard' can be used directly, or
//more safely abstracted with getExternalStorageDirectory()
File storagePath = Environment.getExternalStorageDirectory();
OutputStream output = new FileOutputStream (storagePath + "/" + newname + "/.png");
fileName = storagePath + "/" + newname + "/.png";
try {
byte[] buffer = new byte[5000];
int bytesRead = 0;
while ((bytesRead = input.read(buffer, 0, buffer.length)) >= 0) {
output.write(buffer, 0, bytesRead);
}
} finally {
output.close();
}
} finally {
input.close();
}
}
catch(Exception e){
}
return fileName;
}
public void SetInp(InputStream inp){
string = inp;
}
public class GetDeals extends AsyncTask<Void, Void, Void>{
@Override
protected Void doInBackground(Void... params) {
InputStream str = null;
HttpClient htc = new DefaultHttpClient();
HttpPost htp = new HttpPost("site/android_connect.php");
try {
HttpEntity resp = htc.execute(htp).getEntity();
InputStream strings = resp.getContent();
str = strings;
} catch (ClientProtocolException e) {
Log.d("problema" ,"BAD!");
e.printStackTrace();
} catch (IOException e) {
Log.d("problema" ,"BAD!");
e.printStackTrace();
}
string = str;
return null;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu_choice);
try {
new GetDeals().execute().get();
}
catch(Exception e){}
/* try {
Deals = StreamReader(string);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
/*
for(int i = 0; i<Deals.size(); i++){
ImageBase.add(DownloadImg(Deals.get(i), "Deal"+i));
Log.d("bugger", DownloadImg(Deals.get(i), "Deal"+i));
}
*/
try {
StreamReader();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_choice, menu);
return true;
}
}
so I get this error thrown:

I understand it's saying that I am trying to perform Network action on main thread, but all I am doing is calling StreamReader which I assume just converts InputStream (saved and retrieved from AsyncTask but it throws error.
Any help? What's causing it?
Thank you.
