I am a beginner in android, I make tables in eclipse, and I want to retrieve the information entered by the user to put it in a table named user when pressing on the button REGISTER
What code should I wrote to do that ?
params.add(new BasicNameValuePair("mobile_number", number));
params.add(new BasicNameValuePair("password", pwd));
params.add(new BasicNameValuePair("hint", h));
params.add(new BasicNameValuePair("email_id", id));
JSONObject json = jsonParser.makeHttpRequest(url,"POST", params);
Log.d("Create Response", json.toString());
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1)
{
flag=0;
Intent i = new Intent(getApplicationContext(),Welcome.class);
i.putExtra("mobile_number",number);
i.putExtra("password",pwd);
startActivity(i);
finish();
}
else
{
// failed to Sign in
flag=1;
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;

I am using localhost and MySQL database in my project. i have to insert data in database and then move to next intended activity. The Data is successfully added into database but after that app terminates with window leakage error in logcat.
Code:
class CreateNewCourier extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(PackageDetail.this);
pDialog.setMessage("Adding Details..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/**
* Creating product
* */
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("user_no", "120"));
params.add(new BasicNameValuePair("recp_name", recp_name));
params.add(new BasicNameValuePair("recp_no", recp_no));
params.add(new BasicNameValuePair("recp_adres", recp_adres));
params.add(new BasicNameValuePair("pkg_name", pkg_name));
params.add(new BasicNameValuePair("pkg_quan", pkg_quan));
params.add(new BasicNameValuePair("pickup_adres", pickup_adres));
params.add(new BasicNameValuePair("pkg_type", pkg_type));
params.add(new BasicNameValuePair("veh_type", veh_type));
params.add(new BasicNameValuePair("Breakable", Breakable));
// getting JSON Object
// Note that create product url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_product,
"POST", params);
// check log cat fro response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), Login.class);
startActivity(i);
// closing this screen
finish();
} else {
//failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url) {
//dismiss the dialog once done
pDialog.dismiss();
}
Here is the solution , move this code to onPostExecute() after pDialog.dismiss();
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), Login.class);
startActivity(i);
// closing this screen
finish();
} else {
//failed to create product
}
and also in onDestroy of activity add pDialog.dismiss(); to avoid leakage
I am doing an application that need to send data from android to database. I am doing it using JSONParser. But I got problem when I launched the application, it doesn't send the data to the server. I got and error on "String name = inputName.getText().toString();". Here is it:
protected String doInBackground(String... args) {
String name = inputName.getText().toString();
String date = inputDate.getText().toString();
String time = inputTime.getText().toString();
String latitude = inputLatitude.getText().toString();
String longitude = inputLongitude.getText().toString();
String contacts = inputContacts.getText().toString();
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name", name));
params.add(new BasicNameValuePair("date", date));
params.add(new BasicNameValuePair("time", time));
params.add(new BasicNameValuePair("latitude", latitude));
params.add(new BasicNameValuePair("longitude", longitude));
params.add(new BasicNameValuePair("contacts", contacts));
// getting JSON Object

try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), MainActivity.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**

protected void onPostExecute(String file_url) {

}
}
As the error tells you, you cannot call getText() on a background thread. Instead, move your six getText() calls into a constructor of your AsyncTask, or possibly into an onPreExecute() callback, so the getText() calls are made on the main application thread.
I want to update two Mysql tables with one async task and different params, when save button is clicked. It's working properly when its about one table.. How do I implement such a thing?
The code on doInBackground() is:
// getting updated data
Log.d("aa for save", String.valueOf(aa));
Log.d("bb for save", String.valueOf(bb));
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair(TAG_PID, p_id));
params.add(new BasicNameValuePair(TAG_aa, String.valueOf(aa)));
params.add(new BasicNameValuePair(TAG_bb, String.valueOf(bb)));
JSONObject json = jsonParser.makeHttpRequest(url_update_product,"POST", params);
// getting updated data
// Building Parameters
List<NameValuePair> params_user = new ArrayList<NameValuePair>();
params_user.add(new BasicNameValuePair(TAG_UNAME, uname));
params_user.add(new BasicNameValuePair(TAG_aa, String.valueOf(aa)));
params_user.add(new BasicNameValuePair(TAG_bb, String.valueOf(bb)));
JSONObject json_user = jsonParser.makeHttpRequest(url_update_user_votes,"POST", params_user);
// check json success tag
try {
int success = json.getInt(TAG_SUCCESS);
int success2 = json_user.getInt(TAG_SUCCESS);
if (success == 1 && success2 ==1) {
// successfully updated
Intent i = getIntent();
// send result code 100 to notify about update
setResult(100, i);
finish();
} else {
// failed to update
}
} catch (JSONException e) {
e.printStackTrace();
}
The error I get is :
"java.lang.IllegalArgumentException: View not attached to window manager"
on the activity that has the onActivityResult()
Change two mysql tables in one php script and send success and succes2 in one json from servera
// getting updated data
Log.d("aa for save", String.valueOf(aa));
Log.d("bb for save", String.valueOf(bb));
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair(TAG_PID, p_id));
params.add(new BasicNameValuePair(TAG_UNAME, uname));
params.add(new BasicNameValuePair(TAG_aa, String.valueOf(aa)));
params.add(new BasicNameValuePair(TAG_bb, String.valueOf(bb)));
JSONObject json = jsonParser.makeHttpRequest(url_update_all,"POST", params);
// check json success tag
try {
int success = json.getInt(TAG_SUCCESS);
int success2 = json.getInt(TAG_SUCCESS2);
if (success == 1 && success2 ==1) {
// successfully updated
Intent i = getIntent();
// send result code 100 to notify about update
setResult(100, i);
finish();
} else {
// failed to update
}
} catch (JSONException e) {
e.printStackTrace();
}
example php script
<?php
$aa = $_REQUEST['aa'];
$bb = $_REQUEST['bb'];
$p_id = $_REQUEST['p_id'];
$uname = $_REQUEST['uname'];
//db connect.......
$success=0;
$resttt = "UPDATE table1 SET aa='$aa' ";
$result = mysql_query("$resttt");
if($result) { $success=1; }
$success2=0;
$resttt2 = "UPDATE table2 SET bb='$bb' ";
$result2 = mysql_query("$resttt2");
if($result2) { $success2=1; }
// array for JSON response
$response = array();
// success
$response["success"] = $success;
$response["success2"] = $success2;
// echoing JSON response
echo json_encode($response);
?>
I will make a IsLoggedIn Function with PHP (because i check again the name and password in db), but i get a NetworkOnMainThreadException in my logcat.
What is wrong?
public boolean LoggedIn() {
try {
int success;
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("password", password));
JSONObject json = jsonParser.makeHttpRequest(CHECK_URL, "POST", params);
success = json.getInt(TAG_SUCCESS);
if(success == 1) {
return true;
}
} catch (JSONException e) {
e.printStackTrace();
}
return false;
}
Like the exception says, you can't run network operations on the UI thread on Android. You will need to run them on a separate thread so your application doesn't freeze while you're doing stuff on the network. The most common approach for this is an AsyncTask.
I have data from listview, and I want to save it in my database, here's my code;
listResep = (ListView) findViewById(R.id.listResep);
int leng = listResep.getCount();
for(int i = 0; i < leng; i++) {
resep = listResep.getItemAtPosition(i).toString();
new inputResep().execute();
}
and for inputResep;
class inputResep extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(InputRM.this);
pDialog.setMessage("save Resep..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/**
* Creating product
* */
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("rm", rm));
params.add(new BasicNameValuePair("noregis", noregis));
params.add(new BasicNameValuePair("tanggal", tglinput));
params.add(new BasicNameValuePair("pukul", pukul));
params.add(new BasicNameValuePair("ruper", ruper));
params.add(new BasicNameValuePair("kelas", kelas));
params.add(new BasicNameValuePair("profesi", profesi));
params.add(new BasicNameValuePair("kajian", resep));
params.add(new BasicNameValuePair("id_user", id_user));
params.add(new BasicNameValuePair("tglsave", tglsave));
// getting JSON Object
// Note that create product url accepts POST method
json = jsonParser.makeHttpRequest(URL_INPUT_RESEP,"POST", params);
// check log cat for response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
Log.d("stat", success+"");
if (success > 0) {
// successfully created product
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
Log.d("test", "JSONException"+e.getMessage());
}
return null;
}
/**

* **/
protected void onPostExecute(String file_url) {
pDialog.dismiss();
}
}
but every time I tried to input resep, it only save last data from listview as much as data in listview, ex= listview: data1, data2, data3; save: data3, data3, data3;
Put the whole thing in a FOR LOOP, getting the size of the total views in listview and so for each loop the data will be uploaded in the database!!
after looking at #Exeptional answer, this is how I deal with it;
int leng = listResep.getCount();
Log.d("jml resep", ""+leng);
for(int i = 0; i < leng; i++) {
resep = listResep.getItemAtPosition(i).toString();
Log.d("save resep"+i, resep);
// new inputResep().execute();
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("rm", rm));
params.add(new BasicNameValuePair("noregis", noregis));
params.add(new BasicNameValuePair("tanggal", tglinput));
params.add(new BasicNameValuePair("pukul", pukul));
params.add(new BasicNameValuePair("ruper", ruper));
params.add(new BasicNameValuePair("kelas", kelas));
params.add(new BasicNameValuePair("profesi", profesi));
params.add(new BasicNameValuePair("kajian", resep));
params.add(new BasicNameValuePair("id_user", id_user));
params.add(new BasicNameValuePair("tglsave", tglsave));
// getting JSON Object
// Note that create product url accepts POST method
json = jsonParser.makeHttpRequest(URL_INPUT_RESEP,"POST", params);
// check log cat for response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
Log.d("stat", success+"");
if (success > 0) {
// successfully created product
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
Log.d("test", "JSONException"+e.getMessage());
}
}
EDIT:
it works fine when I tried with emulator, then I tried install in my tablet, at first it works fine, but it didn't work when I tried to save data, so I changed it and put loop in the asyncTask:
class inputResep extends AsyncTask<String, String, String> {
/**
* Creating product
* */
protected String doInBackground(String... args) {
int leng = listResep.getCount();
Log.d("jml resep", ""+leng);
for(int i = 0; i < leng; i++) {
resep = listResep.getItemAtPosition(i).toString();
// Building Parameters

params.add(new BasicNameValuePair("rm", rm));
params.add(new BasicNameValuePair("noregis", noregis));
params.add(new BasicNameValuePair("tanggal", tglinput));
params.add(new BasicNameValuePair("pukul", pukul));
params.add(new BasicNameValuePair("ruper", ruper));
params.add(new BasicNameValuePair("kelas", kelas));
params.add(new BasicNameValuePair("profesi", profesi));
params.add(new BasicNameValuePair("kajian", resep));
params.add(new BasicNameValuePair("id_user", id_user));
params.add(new BasicNameValuePair("tglsave", tglsave));
// getting JSON Object
// Note that create product url accepts POST method
json = jsonParser.makeHttpRequest(URL_INPUT_RESEP,"POST", params);
Log.d("testinput", "4");
// check log cat for response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
Log.d("stat", success+"");
if (success > 0) {
// successfully created product
Log.d("test", "berhasil simpan resep");
} else {
// failed to create product
Log.d("test", "failed to create product ");
}
Log.d("test", "in try");
} catch (JSONException e) {
e.printStackTrace();
Log.d("test", "JSONException"+e.getMessage());
}
}
return null;

}
try useing this one in postexecute in forloop
