this is my php script
<?php
try{
$con = new PDO('mysql:host=localhost;dbname=pfe'/*info db*/,'root'/*login*/, ''/*mdp*/);
}
catch (Exception $e)
{
die('Erreur : '.$e->getMessage());
}
$msg = $_GET['msg'];
$mail = $_GET['mail'];
$result = $con->prepare("INSERT INTO message ( `msg`, `mail`)
VALUES ('{$msg}', '{$mail}')");
$result->execute();
if($result == true) {
echo '{"query_result":"SUCCESS"}';
}
else{
echo '{"query_result":"FAILURE"}';
}
my script i think is good cause i tried it with my browser it works but with android does not insert the data
and this is java class,
EditText msg,mail;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
msg = (EditText) findViewById(R.id.editText);
mail = (EditText) findViewById(R.id.editText2);
}
public void signup(View v) {
String message = msg.getText().toString();
String email = mail.getText().toString();
Toast.makeText(this, "wait...", Toast.LENGTH_SHORT).show();
new Insertinto(this).execute(message, email);
}
public class Insertinto extends AsyncTask<String, Void, String> {
private Context context;
public Insertinto(Context context) {
this.context = context;
}
protected void onPreExecute() {
}
#Override
protected String doInBackground(String... arg0) {
String msg = arg0[0];
String mail = arg0[1];
String link;
String data;
BufferedReader bufferedReader;
String result;
try {
data = "?msg=" + URLEncoder.encode(msg, "UTF-8");
data += "&mail=" + URLEncoder.encode(mail, "UTF-8");
link = "http://192.168.43.93/dysfonction.php" + data;
URL url = new URL(link);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
bufferedReader = new BufferedReader(new InputStreamReader(con.getInputStream()));
result = bufferedReader.readLine();
return result;
} catch (Exception e) {
return new String("Exception: " + e.getMessage());
}
}
this is json
protected void onPostExecute(String result) {
String jsonStr = result;
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
String query_result = jsonObj.getString("query_result");
if (query_result.equals("SUCCESS")) {
Toast.makeText(context, "Data inserted successfully", Toast.LENGTH_SHORT).show();
} else if (query_result.equals("FAILURE")) {
Toast.makeText(context, "Data could not be inserted", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(context, "Couldn't connect to database.", Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(context, "Error parsing JSON data.", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(context, "Couldn't get any JSON data.", Toast.LENGTH_SHORT).show();
}
}
}
}
when i execute it show me "Error parsing JSON data" i didn't find where is the pbm.
debug and check the result received in the postExecute(); and from next time paste the logcat as well..
Try to change this to
if($result == true) {
echo '{"query_result":"SUCCESS"}';
}else{
echo '{"query_result":"FAILURE"}';
}
this
if($result == true) {
$data = array(
'query_result' => 'SUCCESS'
);
}else{
$data = array(
'query_result' => 'FAILURE'
);
}
echo json_encode($data);
It seems to be your java code is so clear. So sent response from php code like above may be works.
in the place of
result = bufferedReader.readLine();
use
result = bufferedReader.readLine().toString();

I have a table in ms sql this table contains FName and FInfo i want to get th FInfo according to the FName like if the FName in the app is equal to john it gets the FInfo of john in the same row.
i have tried everything including query's and Result set but it didn't work out for me.
here is my code:
public class InsideFamily extends AppCompatActivity {
private TextView inf;
private boolean success = false; // boolean
private ConnectionClass connectionClass;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_inside_family);
getSupportActionBar().hide();
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
inf = (TextView) findViewById(R.id.thefamilyinf);
connectionClass = new ConnectionClass();
SyncData orderData = new SyncData();
orderData.execute("");
}
private class SyncData extends AsyncTask<String, String, String> {
String msg = "No Data Found";
ProgressDialog progress;
#Override
protected void onPreExecute()
{
progress = ProgressDialog.show(InsideFamily.this, "Synchronising",
"Please Wait...", true);
}
#Override
protected String doInBackground(String... strings)
{
runOnUiThread(new Runnable() {
#Override
public void run() {
try {
Connection conn = connectionClass.CONN();
if (conn == null) {
msg = "Please Check Your Connection";
success = false;
} else {
String gettingfam = getIntent().getStringExtra("defamily");
String query = "SELECT * FROM family where FName='" + gettingfam + "'";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query);
if (rs != null) {
while (rs.next()) {
try {
inf.setText((rs.getString("FInfo")));
} catch (Exception ex) {
ex.printStackTrace();
}
}
msg = "Found";
success = true;
} else {
msg = "No Data found!";
success = false;
}
}
} catch (Exception e) {
e.printStackTrace();
Writer writer = new StringWriter();
e.printStackTrace(new PrintWriter(writer));
msg = writer.toString();
success = false;
}
}
});
return msg;
}
#Override
protected void onPostExecute(String
msg)
{
progress.dismiss();
Toast.makeText(InsideFamily.this, msg + "", Toast.LENGTH_LONG).show();
if (success == false) {
} else {
try {
} catch (Exception ex) {
}
}
}
}
}
the errors i get is that it brings a toast for me saying that "No Data Found!"
which means that that the result set equals null how can i fix it??
I found the answer
the wrong was in the query
because its nvarchar i have to wright
"SELECT * FROM family WHERE FName = (N'" +dta+ "')"
rather than
"SELECT * FROM family where FName='" + gettingfam + "'"

So i'm into a tutorial at Udemy "The Complete Android N Developer Course" and trying to make lecture 86 about a weather app.
I use the API from here https://openweathermap.org/current#cityid and use JSON to get the data needed.
The app is working properly when i input a correct city name, but when the input is wrong or empty the app crashes without catching any exceptions.
I don't know why it is crashing and where to look. So i give you all the code i wrote. I tried to implement if statements here and there to try and find it but without any luck.
I would like to know where the problem is and how to fix it so the app doesn't crash anymore.
Thanks in advance.

It is because you're trying to changes UI with background thread inside the doInBackground(Params...) method of AsyncTask with this line:
try {
...
return result;
} catch (MalformedURLException e1) {
Toast.makeText(MainActivity.this, "MalformedURLException", Toast.LENGTH_SHORT).show();
} catch (IOException e2) {
Toast.makeText(MainActivity.this, "IOException", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(MainActivity.this, "General exception (doInBackground)", Toast.LENGTH_SHORT).show();
}
You should not call Toast inside the doInBackground(Params...). Do that inside the onPostExecute(Result).
You can avoid that by either ignoring the error or returning specific text in doInBackground. Something like this:
public class DownloadTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
String result = "";
...
try {
...
return result;
} catch (MalformedURLException e1) {
result= "MalformedURLException";
} catch (IOException e2) {
result= "IOException";
} catch (Exception e) {
// do nothing and returning empty
result= "Exception";
}
return result;
}
#Override
protected void onPostExecute(String result) {
// check if there is an error
String errorMessage = "";
switch(result) {
case "MalformedURLException":
errorMessage = "MalformedURLException";
break;
case ""IOException":
errorMessage = "IOException";
break;
case "Exception":
errorMessage = "Exception";
break;
}
// there is an error, show a message.
if(!errorMessage.isEmpty()) {
Toast.makeText(MainActivity.this, "Could not find weather: " + errorMessage, Toast.LENGTH_SHORT).show();
return; // stop the process.
}
// do something when no error found.
}
}
I have an app where I use the info provided by the user to get a list of data
Using the code below, I'm getting two different results:
When where username = '$username' is presented on the PHP side, I receive just the Toast message. However, ListView remains empty.
When I remove where username = '$username' from PHP side, Toast message is displayed and the ListView also shows some content
Could you please help me to undestand why the ListView remains empty on that specific case?
Thanks in advance

Below is a registration form where user can register a new account, however when I try to sign up it connect to the server, but for some reason it failed to register!
with message from php file (Hmmm Look Like User Already Exist...) however I'm sure that the user doesn't exist in the database table!

I have two functions, one is update and another is updateWithoutImage. They using the same php. But the php works for updateWithoutImage but not for update function.
ok,I know why the update() does not functioning.
In my php code, I have two $id. Change the $id inside the if(isset($_POST['image'])) to $id1, and now it can be updated.
