What am i doing wrong.Granted i don't know much java.

{"result":[{"id":"7","nama":"sadasdas","kategori":"berkendara","pesan":"dasdasda‌​sdasd"},{"id":"5","nama":"Menggati Ban Bocor","kategori":"berkendara","pesan":"asdsadasdas"}]}

Well you can try this way if you are getting proper JSON response:
...

try {

Android Application Force closing (retrieving data)

According to your LogCat message:
Caused by: java.lang.NullPointerException at com.example.trackstatus.ViewTrackingStatusActivity.onCreate(ViewTrackingStatusActivity.java:55)
You are missing :
setContentView(R.layout.your_layout);
where your EditText trackingNumberText must be declared.
thats the reason for what trackingNumberText is null
trackingNumberText = (EditText) findViewById(R.id.trackingNumberText);
More info:
setContentView() method
Update:
Since you have this new exception: NetworkOnMainThreadException
android.os.NetworkOnMainThreadException at android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1133)
you have to implement the use of AsyncTask
And hey! you don´t need to use runOnUiThread inside the doInBackground() method of the Asynctask :P:
protected String doInBackground(String... params) {
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
Move the lines that implies operations on UI thread like
Toast.makeText(getApplicationContext(),"Service not found!",Toast.LENGTH_LONG).show();
to the onPostExecute() method of the Asynctask

The error is in Line55
String trackingno = trackingNumberText.getText().toString();
trackingNumberText is NULL
instead try to do NULL check
String trackingno = "";
if(trackingNumberText.getText().length() > 0)
{
trackingno = trackingNumberText.getText().toString();
} else {
Toast.makeText(getApplicationContext(), "Enter values", Toast.LENGTH_LONG).show();
return;
}
EDIT:
You have to send all requests to server in Background Thread, use AsyncTask
Here is the detailed example for performing Network Operation.

Any help is much appreciated!

your URL string is wrong, you wrote it like:
Private static String url_all_products = "http://http://000100023.host56.com/db_all.php";
it should be:
Private static String url_all_products = "http://000100023.host56.com/db_all.php";
one http:// is enough ;)

i don't know where the problem is, please help me
is my code incorrect ???
if any one have correct code please give it to me i am using codeigniter for php and this is the code that i call it above
function register_get()
{
$json = array('status' => false );
if($this->input->post()==null){
$this -> response($json, 200);
}
$firstname = $this->post("first_name");
$lastname = $this->post("last_name");
$password = $this->post("password");
if(!$firstname || !$lastname || !$password){
$json['status'] = "wrong insert";
$this -> response($json, 200);
}
$this->load->model('Data_model');
$result = $this->Data_model->search($firstname, $lastname);
if($result)
{
$this->Data_model->insert($firstname,$lastname,$password);
$json['status'] = true;
}
// here if false..
$this -> response($json, 200);
}

There are issues with your PHP. You are not passing back any JSON. You will need to change your script to encode your array into JSON.
$result = json_encode($json)
Returning the actual JSON will help. Make sure you are not returning any HTML either. Your Java is trying to parse a JSON response, but you are responding with <!DOCTYPE...

Android: Inserting space in an edittext causes a crash

My edit text serves as a search box, and I am getting movies from rotten tomatoes API, using the text inside my edit text, problem is. when a space is inserted the application crashes, I am assuming that I need to convert the spaces into +'s, but I have no clue how where to add this code or how exactly, I hope someone here will be able to help me.

You should use standard URL encoding as follows:
case R.id.bGo:
new RequestTask()
.execute("http://api.rottentomatoes.com/api/public/v1.0/movies.json?apikey="
+ API_KEY
+ "&q="
+ URLEncoder.encode(searchBox.getText(), "UTF-8")
+ "&page_limit=" + MOVIE_PAGE_LIMIT);
This will replace spaces and all other non-URL-friendly characters with allowed characters (as defined by RFC 1738 and the HTML spec)

Need to see your logcat to make sure that's the actual problem, but from your code it looks like it is at least one of your issues.
Ideally you'd do something like
String search = searchBox.getText();
search = search.replace(" ", "+");
and then use that variable to send to your RequestTask

Conversely, you may be better off doing a full encoding on the string returned instead of just replacing spaces... as other characters will cause you issues as well (?, &, etc)
EDIT: See EJK's answer for the URLEncoding version.
