Android code to connect PHP response changed to null

Android code to connect PHP response changed to null - java

I'm facing problem in getting a response back in android from PHP.
First, it gets the right response in try then I don't know what cause problem it goes to catch and change response to null. My PHP files are perfectly working I tested them by giving default values.
Below is the code:
This class is used to connect to server and send data to PHP:
public class DatabaseFunctionality extends AsyncTask <String, String, String>{
int flag;
Context context;
String username;
String password;
String rname;
String city;
int mnum;
String sname;
String area;
String sadd;
int snum1;
int snum2;
String cpic;
String ppic;
Bitmap coverpic, profpic;
public String resp;
//public String r;
StringBuilder sb;
public DatabaseFunctionality(Context context, int f){
this.context=context;
this.flag=f;
}
#Override
protected String doInBackground(String... params) {
if(this.flag==0){
username=params[0];
password=params[1];
resp = login();
}
else if(this.flag==1){
rname = params[0];
username = params[1];

mnum = Integer.parseInt(params[4]);
sname = params[5];

snum1 = Integer.parseInt(params[8]);
snum2 = Integer.parseInt(params[9]);
resp = signup();
}
return resp;
}

Android Studio org.json.JSONException: Value <br of type java.lang.String cannot be converted to JSONObject

I'm trying to post some data using volley to a server.
The issue seems to with an encoded string image.
On this line
String name = namefield.getText().toString();
String age = agefield.getText().toString();
String gender = genderfield.getText().toString();
String color = colorfield.getText().toString();
String notes = notesfield.getText().toString();
String images = encodeImage(bitmap);
updatedetails(name, age, gender, color, notes, String.valueOf(owner), String.valueOf(id), images);
if I change image to empty string
updatedetails(name, age, gender, color, notes, String.valueOf(owner), String.valueOf(id), "");
then than the data sends to server, which is how I know the image is the problem.
I logged the image response and this is what I get:

And then where I submit:

String images = encodeImage(bitmap);
updatedetails(name, age, gender, color, notes, String.valueOf(owner), String.valueOf(id), images);
Log.d("Strings",images );
Log.d("Strings",color );

image response is ok. you must set image data type as LONGTEXT or LONGBLOB on database server. but a better solution is to use Multipart Image Upload for upload image on server.
you can try with Uploading Images to Server android

Registering with a new account failed

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!

android java run activity without restarting it

I created simple application which would login to DB and get data from it. But now I found a problem: If you in the first time write wrong login data and try to login second time it won't work. You have to restart it.
I think there is a problem in this code: EDITED
public class MyMoodleApplicationActivity extends Activity {
/** Called when the activity is first created. */
EditText username;
EditText password;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
username = (EditText)findViewById(R.id.username);
password = (EditText)findViewById(R.id.password);
final Button loginButton = (Button)findViewById(R.id.login);
loginButton.setOnClickListener(loginListener);
final Button clearButton = (Button)findViewById(R.id.clear);
clearButton.setOnClickListener(clearListener);
}
private OnClickListener loginListener = new OnClickListener(){
public void onClick(View v){
String usr = username.getText().toString();
String psw = password.getText().toString();
System.out.println("Username: "+usr);
System.out.println("Password: "+psw);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("usern",""+usr));
nameValuePairs.add(new BasicNameValuePair("passw",""+psw));
InputStream is = null;
String result = "";
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://ik.su.lt/*****");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
}
//convert response to string
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result "+e.toString());
}
String usernameFromDB = "";
String firstnameFromDB = "";
String lastnameFromDB = "";
String emailFromDB = "";
String phoneFromDB = "";
String skypeFromDB = "";
String cityFromDB = "";
String descriptionFromDB = "";
try{
JSONArray jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
usernameFromDB = json_data.getString("username");
firstnameFromDB = json_data.getString("firstname");
lastnameFromDB = json_data.getString("lastname");
emailFromDB = json_data.getString("email");
phoneFromDB = json_data.getString("phone1");
skypeFromDB = json_data.getString("skype");
cityFromDB = json_data.getString("city");
descriptionFromDB = json_data.getString("description");
System.out.println(usernameFromDB+ " " + firstnameFromDB+" "+lastnameFromDB+" "
+ emailFromDB + " " + phoneFromDB +" " + skypeFromDB+ " " + cityFromDB + " "+
descriptionFromDB);
}
}
catch(JSONException e){
AlertDialog alertDialog = new AlertDialog.Builder(MyMoodleApplicationActivity.this).create();
alertDialog.setTitle("Klaida!");
alertDialog.setMessage("Toks vartotojas neegzistuoja");
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
return;
}
});
alertDialog.show();
Log.e("log_tag", "Error parsing data "+e.toString());
}
if(usr.length()== 0){
AlertDialog alertDialog = new AlertDialog.Builder(MyMoodleApplicationActivity.this).create();
alertDialog.setTitle("Klaida!");
alertDialog.setMessage("Jūs neįvedėte slapyvardžio");
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
return;
}
});
alertDialog.show();
}
else if(psw.length()==0){
AlertDialog alertDialog = new AlertDialog.Builder(MyMoodleApplicationActivity.this).create();
alertDialog.setTitle("Klaida!");
alertDialog.setMessage("Jūs neįvedėte slaptažodžio");
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
return;
}
});
alertDialog.show();
}
else if (usr.equals(usernameFromDB)){
Intent in = new Intent(getApplicationContext(), LoggedUser.class);
in.putExtra("firstname", firstnameFromDB);
in.putExtra("lastname", lastnameFromDB);
in.putExtra("email", emailFromDB);
in.putExtra("phone1", phoneFromDB);
in.putExtra("skype", skypeFromDB);
in.putExtra("city", cityFromDB);
in.putExtra("description", descriptionFromDB);
startActivity(in);
finish();
}
}};
private OnClickListener clearListener = new OnClickListener(){
#Override
public void onClick(View v){
username.setText("");
password.setText("");
}
};
In these if statements I check if username and password you enter is empty username is not equal to the one in database.
How to rewrite the code that it would work?
Edited:
I have user john in DB but if I write John in login field and press login button it won't say that there is not the John user. And in LogCat I see that json stream is readed. Is there a way to set up a rule that upercase and lowercase letters would be different?
