Pass Connection Between Intents

I am building an android application to do various queries on my MySQL database. Once a successful login has returned on the main activity, I create a new Intent that holds search and query options. Here's the issue I am having. I keep getting a null pointer exception on stmt = con.createStatement(); Below is my logcat:
Code:
08-20 16:12:07.359 654-810/com.android.exchange D/ExchangeService: !!! deviceId unknown; stopping self and retrying

08-20 16:12:12.379 278-278/system_process W/ActivityManager: Unable to start service Intent { act=com.android.email.ACCOUNT_INTENT } U=0: not found
I'm curious whether it is better practice to close the connection and reopen it in the new intent? Or pass the connection between intents somehow?
Any input would be greatly appreciated!

wait...
Here are snippets of my code to help debug.
Code:
[user=439709]@override[/user]
public void onClick(View view) {
if(view.getId() == R.id.LoginButton) {
Toast.makeText(getApplicationContext(), "Attempting Connection", Toast.LENGTH_SHORT).show();
//Spawn new thread
new Thread(new Runnable() {
public void run() {
if(net.execLogin(mUserInput.getText().toString(), mPassInput.getText().toString())) {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "Connected to Database", Toast.LENGTH_LONG).show();
}
});
//start new activity
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
[user=439709]@override[/user]
public void run() {
Intent intent = new Intent(LoginActivity.this, ControlActivity.class);
startActivity(intent);
}
});
}
else {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "Connection Failed :(", Toast.LENGTH_LONG).show();
}
});
}
}
}).start();
}
}
And here is the new activity started by the above code:
Code:
package com.example.testapplication;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
import java.util.ArrayList;
public class ControlActivity extends Activity implements View.OnClickListener {
private ArrayList<Hardware> list = new ArrayList<Hardware>();
EditText mEditText;
ListView mListView;
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_control);
setupPage();
}
public void setupPage() {
Button search = (Button)findViewById(R.id.search);
search.setOnClickListener(this);
mEditText = (EditText)findViewById(R.id.editText);
mListView = (ListView)findViewById(R.id.listView);
}
[user=439709]@override[/user]
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.control, menu);
return true;
}
public void onClick(View view) {
if(view.getId() == R.id.search) {
new Thread(new Runnable() {
public void run() {
list = new Networking().Search("Type", mEditText.getText().toString());
}
}).start();
ArrayAdapter<Hardware> adapter = new ArrayAdapter<Hardware>(this, android.R.layout.simple_list_item_1, list);
adapter.notifyDataSetChanged();
mListView.setAdapter(adapter);
if(list == null) {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "0 Results Yielded :(", Toast.LENGTH_SHORT).show();
}
});
}
}
}
}
And here is the code I use to connect and query the database
Code:
import java.sql.*;
import java.util.*;
public class Networking implements DbQuery {
private static final String DRIVER = "org.mariadb.jdbc.Driver";
private static final String URL = "jdbc:mysql://146.187.16.32/Peirce";
ArrayList<Hardware> ara = new ArrayList<Hardware>();
Database db = new Database();
Hardware h1;
Connection con = null;
Statement stmt = null;
public boolean execLogin(String uName, String pWord) {
try {
Class.forName(DRIVER);
con = DriverManager.getConnection(URL, uName, pWord);
if(!con.isClosed()){
return true;
}
return false;
}catch(SQLException e) {
e.printStackTrace();
}catch(ClassNotFoundException e) {
e.printStackTrace();
}
return false;
}
public ArrayList<Hardware> Search(String arg, String target) {
try {
stmt = con.createStatement(); //throws null pointer exception
ResultSet rs = stmt.executeQuery("Select * from " + db.getTable() + " where " + arg + "='" + target + "';");
while(rs.next()) {
ara.add(new Hardware(rs.getString("Type"), rs.getString("Make"), rs.getString("Model"), rs.getString("Serial"), rs.getString("Comments")));
}
return ara;
}catch(SQLException e) {
e.printStackTrace();
}catch(NullPointerException e) {
e.printStackTrace();
}
return ara;
}

nevermind
i have figured it out.

[Q] Sockets in Android

SOLVED. please lock.
I have 2 buttons, Server and Client.
The server button contain a textview which prints stuff received from the client.
The client button open Editbox and Send button which uses OnClick function.
In debug mode everything works fine.
When I run them independently and playing with ON/OFF SocketServer and Existing/New SocketClient the program would mostly get stuck and sometimes i get flowed with "Client says: null"
It usually happens when I click in device1 on Server Button, in device2 on client -> send a message from device2 to device1 and it successes -> close server on device1 -> send about 3 messages on device2 (remember that the serverSocket is closed) -> open server on device1 -> close and open client on device2.
The app also getting stuck randomaly after some turn off screen and turn on using the power button while playing with buttons.. and I cant find the issue.

CursorTreeAdapter with search implementation

I make an application for Android and I'm using CursorTreeAdapter as ExpandableListView. Now I want to use search box for display the filtered ExpandableListView items. Like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",

I have very considerably simplified and cleaned the code (so that you guys that not need to do).
As you can see, I've in total 3 cursors (1 for the groups and 2 for the children). The data is synced from a local database and put in a Content Provider. (The database is from here and the provider from here). From there I insert it into the CursorTreeAdapter. (The most of the loader functions is from here).
The only thing is now how do I implement a search? Should I do it trough Content Provider or a raw query in the database? I would like that the results of both children tables is displayed. I think because it's easy to make a fault while typing that `tokenize=porter` is a option in my case.
I've tried this in MyListAdapter.java (with FilterQueryProvider as someone suggested on Stack Overflow):
Code:
public void filterList(CharSequence constraint) {
final Cursor oldCursor = getCursor();
setFilterQueryProvider(filterQueryProvider);
getFilter().filter(constraint, new FilterListener() {
public void onFilterComplete(int count) {
// assuming your activity manages the Cursor
// (which is a recommended way)
notifyDataSetChanged();
// stopManagingCursor(oldCursor);
// final Cursor newCursor = getCursor();
// startManagingCursor(newCursor);
// // safely close the oldCursor
if (oldCursor != null && !oldCursor.isClosed()) {
oldCursor.close();
}
}
});
}
private FilterQueryProvider filterQueryProvider = new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
// assuming you have your custom DBHelper instance
// ready to execute the DB request
String s = '%' + constraint.toString() + '%';
return mActivity.getContentResolver().query(CfpContract.Classes.CONTENT_URI,
MyListAdapter.CLASSES_PROJECTION,
CfpContract.Classes.CLASS_NAME + " LIKE ? OR " + CfpContract.Classes.CLASS_CAT + " LIKE ?",
new String[] { s, s },
null);
}
};
And this in MainActivity.java:
Code:
search.setOnQueryTextListener(new OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
listAdapter.filterList(query);
expandAll();
return false;
}
@Override
public boolean onQueryTextChange(String query) {
listAdapter.filterList(query);
expandAll();
return false;
}
});
search.setOnCloseListener(new OnCloseListener() {
@Override
public boolean onClose() {
listAdapter.filterList("");
expandAll();
return false;
}
});
But then I get these errors when I try to search:
Code:
12-20 13:20:19.449: E/CursorWindow(28747): Failed to read row 0, column -1 from a CursorWindow which has 96 rows, 4 columns.
12-20 13:20:19.449: D/AndroidRuntime(28747): Shutting down VM

What I'm doing wrong? Or is this because I'm only return 1 query (Classes) instead of 2 (Classes and Teachers) in runQuery?
I hope that someone can point me in a good direction.

Face Detection in Background Service

I am making an android app which requires to capture image using front camera using android service. Also we need to detect face in the image so obtained. But when calling the detectfaces() function, the app unfortuantely stops. I am posting the code for it here. Please help me find out where i am going wrong.
here is my code..!!!!

Image positioning in Listview search

I have a problem with the pictures when I use the search then the app always takes the first picture instead of the picture that belongs.
I added two pictures where you can see what I mean by "Adrenaline".
Can someone help me by chance?
I would be very happy.
Sorry for my bad English.
