I'm new in Android Programming, and I'm stuck in a middle of SQL query with Where condition. I want to store my data from database into an arraylist. But my script's always fail with Error message. Anyone have a clue? Thanks before

and this is my ServiceHandler.java

and the result is :
alert box with no message, and dissmiss button (sorry i cant post a pic hehe)
mysql_query("SELECT * from tbkosan where harga <='$harga' and gender='$gender'");
I had the same problem AS THIS one of yours i have chosen to use volley library on android part where it helped me to pass input variable to php where clause
refer to this post and check the answer:
How to parse multiple rows with jsonOject
or follow the followithing tutorial watch function called function StoreUserInfo and refer to second part to activity called RegisterActivity.java these can help you to fetch using where clause:
https://www.androidtutorialpoint.com/androidwithphp/android-login-and-registration-with-php-mysql/
I need advice about my code.
I'm trying to parse a JSON array generated by the PHP function json_encode().
My json:
{"data": [{"streamer":"froggen","yt_length":"25078"},{"streamer":"wingsofdeath","yt_length":"8979"},{"streamer":"guardsmanbob","yt_length":"4790"},{"streamer":"kaostv","yt_length":"4626"},{"streamer":"kungentv","yt_length":"3883"},{"streamer":"destiny","yt_length":"3715"},{"streamer":"zekent","yt_length":"3428"},{"streamer":"athenelive","yt_length":"1673"},{"streamer":"frommaplestreet","yt_length":"1614"},{"streamer":"keyorikeys","yt_length":"1410"},{"streamer":"riotgamesturkish","yt_length":"1397"},{"streamer":"vman7","yt_length":"1022"},{"streamer":"tiensinoakuma","yt_length":"967"},{"streamer":"affenklappe","yt_length":"748"},{"streamer":"teamkeyd","yt_length":"747"},{"streamer":"lagtvmaximusblack","yt_length":"683"},{"streamer":"lolgameru","yt_length":"665"},{"streamer":"gruntartv","yt_length":"585"},{"streamer":"entenzwerg","yt_length":"579"},{"streamer":"lolgameru_cauthonpro","yt_length":"506"},{"streamer":"basickz","yt_length":"488"},{"streamer":"ilysuiteheart","yt_length":"491"},{"streamer":"kireiautumn","yt_length":"485"},{"streamer":"ultimavv","yt_length":"471"}]}
Java class:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
String response = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
try {

HttpGet httpPost = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {

}
}
And my activity:
public class AndroidJSONParsingActivity extends ListActivity {

private static String url = "http://ololo.tv/vasa";
// JSON Node names
private static final String TAG_DATA = "data";

}
I tried using breakpoints, and see that when I put a breakpoint after GetEntity, the program doesn't get there because it crashed early, or something.
This my async task.

}
ListAdapter error, seems like something wrong in "this". This my version how cut off code, where it stop return variables. Sorry for bad english, but i hope you understand me :)
Add my php json maker. Mb problem there?!
<?php
mysql_connect("localhost","root","");
if (!mysql_select_db("ololo")) {
echo "Unable to select ololo: " . mysql_error();
}
$sql=mysql_query("select streamer, yt_length from pm_videos where category='1'");
if(!$sql) exit("Error - ".mysql_error().", ".$tmp_q);
while($row=mysql_fetch_assoc($sql)){
$output[]=$row;
}
$json = json_encode($output);
header('Content-Type: application/json');
print "{\"data\": ${json}}";
mysql_close();
?>
You programm crashes because you are running
json = Parser.getJSONFromUrl(url);
in the UI Thread context. You have to use an AsyncTask
Code looks good. The only problem is that
public class ParsingTask extends AsyncTask<String, Void, ArrayList<HashMap<String, String>>>{
JSONParser Parser = new JSONParser();
protected Void doInBackground(String... urls) {
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String, String>>();
JSONObject json = Parser.getJSONFromUrl(url);
try {
// Getting Array of Contacts
data = json.getJSONArray(TAG_DATA);
// looping through All Contacts
for(int i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
// Storing each json item in variable
String streamer = c.getString(TAG_STREAMER);
String viewers = c.getString(TAG_VIEWERS);
//String link = c.getString();
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_STREAMER, streamer);
map.put(TAG_VIEWERS, viewers);
//map.put(TAG_URL, link);
// adding HashList to ArrayList
dataList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
return dataList;
}
protected void onPostExecute(ArrayList<HashMap<String, String>> dataList) {
ListAdapter adapter = new SimpleAdapter(AndroidJSONParsingActivity.this, dataList,
R.layout.list_item,
new String[] { TAG_STREAMER, TAG_VIEWERS /*TAG_URL*/ }, new int[] {
R.id.streamer, R.id.viewers /*R.id.url*/ });
setListAdapter(adapter);
}
Have you heard about gson (docs)?
public static final class Content {
#SerializedName("streamer") // you don't need to specify this, JFYI
String streamer;
#SerializedName("yt_length") // you don't need to specify this, JFYI
String yt_length;
}
public static final class Data {
#SerializedName("data")
List<Content> data;
}
public static void main (String[] args) {
Gson gson = new GsonBuilder().create();
Data data = gson.fromJson(jsonString, Data.class);
}
And remember, you cannot call network operations on UI thread! this is reason of what you have for now.

I'm saving two parts of data the users password and username to use at a later data and a random combination of letters to then check when the app is executed again to avoid the login screen again.
I had this working yesterday and for some reason, I expect I misplaced code when adding a feature and now cannot get it working again, I've tried all day to fix it and yet I cannot.
EDIT1: For some reason, it goes to the else statement on the "CheckPrefs" method, which I CANNOT UNDERSTAND.
EDIT2: It saves the preferences fine and goes to the intent but, it just can't read it.
Code:

public static final String PREFS_CHECK = "CheckSignedIn";
public static final String UID ="";

need to see where you are saving your preferences, so we can match it up with how you're calling your preferences... but, is this a typo?
public static final String PREFS_NAME = "MyPregs";
Should it be "MyPrefs" instead of "MyPregs"?
You have
if (SCheck1 != null && equals(UID))
but do you maybe mean to say
if (SCheck1 != null && !SCheck.equals(UID))
?
You could use the 'reverse comparison' pattern too:
if (UID.equals(SCheck1)) {
} else {
}
This way, you don't have to bother checking SCheck1 == null. UID.equals(null) will return false instead of null.equals(UID) throwing a NullPointerException.
