I am calling a url to fetch data and insert in my database. I have provided a no internet check. If I open the app without internet connection, it works fins, a pop up comes.. But if I connect to the url when I have internet and the internet goes in middle the process, my app crashes, How to fix it?
My code:
public class DoPOSTPen extends AsyncTask<String, Void, Boolean> implements OnCancelListener {
@SuppressWarnings("deprecation")
@Override
protected Boolean doInBackground(String... arg0) {
try {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://testapi.pharmeazy.in/api/MediEazy/GetAllInvoices");
request.addHeader("Authorization", " basic NDlyaWNva2pvaWQwM2ptZGlraWRES09qZGZpamRmNzY0dDA4NWp6MzcyOHdzMkpJS1M4MTA0c2NvcTJ1OTRkazphd0VEMzI3MkA4WWFzZEU3MjI3IUBeIypVSFMq");
request.setHeader(HTTP.CONTENT_TYPE, "application/json");
System.out.println("PRIINTING");
HttpResponse response = null;
try {
response = client.execute(request);
Log.d("Response of GET request", response.toString());
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
InputStream inputStream = response.getEntity().getContent();
String result = Utils.convertInputStreamToString(inputStream);
System.out.println("server response is :" + result + "\n" + inputStream);
try {
ja=new JSONArray(result);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
catch (Exception e) {
Log.e("ClientServerDemo", "Error:", e);
toastText2 = "Connection Error !";
}
return true;
}
protected void onPreExecute() {
//display the progress dialog
mProgressHUD2 = ProgressHUD.show(Med.this,"Getting Rejected Orders", true,false,this);
}
@Override
protected void onPostExecute(Boolean valid) {
mProgressHUD2.dismiss();
// if server response is successful
for(int i=0;i<ja.length();i++){
try {
jo=ja.getJSONObject(i);
db.insertLabel(jo.get("Id").toString(), jo.get("CustomerId").toString(), jo.get("PharmacyId").toString(),
jo.get("DeliveryAddress").toString(), jo.get("DeliveryName").toString(),
jo.get("OrderStatus").toString(),jo.get("PrescriptionAttached").toString(),jo.get("Discount").toString());
}
catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
new DoPOST3().execute();
}
