My Android application runs on emulator but not working on my android device

My application works fine on android emulator. When I'm trying to run it on my device LogCat column gives me info that there is no such columns: USERNAME.
On emulator my SQLite database is created normally and I can add new users and sign but in device there is an exception when I'm trying doing this.
Here is a Log file when i'm trying to create new user:

Anyone could help?

You may have changed the DB schema without increasing DATABASE_VERSION and thus the new app is finding the old DB.
static final int DATABASE_VERSION=2;
should fix it.

Try to uninstall Application on device and rerun it.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textviewres"
android:layout_width="match_parent"
android:layout_height="match_parent" >
remove ID from this
relative layout and textview both have same id and when you get it in activity it is returning the ralative layout object.
Remove it from relative layout just keep it in textview

Please post your xml layout or check if this line is correct:
TextView result = (TextView) findViewById(R.id.textviewres);
Is the view with id textviewres really TextView? According logcat looks like it's RelativeLayout
You have duplicated view id. Try to use this layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true" >
</ListView>
<TextView
android:id="#+id/textviewres"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="TextView" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="38dp"
android:text="TextView" />
</RelativeLayout>

In your code:
convertView = mInflater.inflate(R.layout.display_db_result,parent, false);
You need to inflate layout which contains only TextView.

How to solve NullPointerExpression in Android?

I have a problem while using a database. When I run my SQLView.java, I get a fatal exception. I'll post all my database-related code.
See my commenting lines on Database class (line 71), and SQLView class (Line 14). Maybe there is something wrong? I've tried many things like put in: this, of null.
Also, I've read all related nullpointerexception-question on this website.
To begin: my Database class:
package com.jacob.eindproject;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.database.sqlite.SQLiteDatabase.CursorFactory;
import java.sql.*;
public class Database {
public static final String KEY_ROWID = "_id";
public static final String KEY_NAME = "persons_name";
public static final String KEY_HOTNESS = "persons_hotness";
private static final String DATABASE_NAME = "Databasedb";
private static final String DATABASE_TABLE = "peopleTable";
private static final int DATABASE_VERSION = 1;
private DbHelper ourHelper;
private final Context ourContext;
private SQLiteDatabase ourDatabase;
private static class DbHelper extends SQLiteOpenHelper{
public DbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
// TODO Auto-generated constructor stub
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" +
KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
KEY_NAME + " TEXT NOT NULL, " +
KEY_HOTNESS + " TEXT NOT NULL);"
);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
onCreate(db);
}
public void close(Database database) {
// TODO Auto-generated method stub
}
}
public Database(Context c){
ourContext = c;
}
public Database open() throws SQLException{
ourHelper = new DbHelper(ourContext);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}
public void close() {
ourHelper.close(); //This is line 71, where also an error is given, maybe there should me text between the brackets ()?
}
public long createEntry(String name, String hotness) {
ContentValues cv = new ContentValues();
cv.put(KEY_NAME, name);
cv.put(KEY_HOTNESS, hotness);
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
public String getData() {
// TODO Auto-generated method stub
String[] columns = new String[]{ KEY_ROWID, KEY_NAME, KEY_HOTNESS};
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null);
String result = "";
int iRow = c.getColumnIndex(KEY_ROWID);
int iName = c.getColumnIndex(DATABASE_NAME);
int iHotness = c.getColumnIndex(KEY_HOTNESS);
for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()){
result = result + c.getString(iRow) + " " + c.getString(iName) + " " + c.getString(iHotness) + "\n";
}
return result;
}
}
The SQLite class, to fix the input:
package com.jacob.eindproject;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.app.Activity;
import android.app.Dialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.view.View.OnClickListener;
public class SQLite extends Activity implements View.OnClickListener {
Button sqlUpdate, sqlView;
EditText sqlName, sqlHotness;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sqllite);
sqlUpdate = (Button) findViewById(R.id.bSQLUpdate);
sqlName = (EditText) findViewById(R.id.etSQLName);
sqlHotness = (EditText) findViewById(R.id.etSQLHotness);
sqlView = (Button) findViewById(R.id.bSQLopenView);
sqlView.setOnClickListener((android.view.View.OnClickListener) this);
sqlUpdate.setOnClickListener((android.view.View.OnClickListener) this);
}
public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.bSQLUpdate:
boolean didItWork = true;
try{
String name = sqlName.getText().toString();
String hotness = sqlHotness.getText().toString();
Database entry = new Database(SQLite.this);
entry.open();
entry.createEntry(name, hotness);
entry.close();
}catch (Exception e ){
didItWork = false;
}finally{
if (didItWork){
Dialog d = new Dialog(this);
d.setTitle("Heak Yeay");
TextView tv = new TextView(this);
tv.setText("Succes");
d.setContentView(tv);
d.show();
}
}
break;
case R.id.bSQLopenView:
Intent i = new Intent("com.jacob.eindproject.SQLVIEW");
startActivity(i);
}
}
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub
}
}
After that, my SQLView class, to view the input from the SQLite class:
package com.jacob.eindproject;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class SQLView extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sqlview);
TextView tv = (TextView) findViewById(R.id.tvSQLinfo);
Database info = new Database(this); //as you can see in the logcat, this is line 14, where the error is. Maybe the "this" isn't right?
info.open();
String data = info.getData();
info.close();
tv.setText(data);
}
}
Now, my xml files, maybe I haven't configured a button not well, or something?
SQLView.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="#+id/tableLayout1">
<TableRow>
<TextView android:text="#string/Names" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"/>
<TextView android:text="#string/Hotness" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" />
</TableRow>
</TableLayout>
<TextView android:id="#+id/tvSQLinfo" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="#string/info"/>
</LinearLayout>
The sqllite.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

android:orientation="vertical"
android:layout_width="match_parent"

<TextView

android:text="#string/hotnessscale"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<EditText
android:id="#+id/etSQLHotness"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</EditText>
<Button
android:id="#+id/bSQLUpdate"
android:text="#string/Update"
android:layout_width="wrap_content"
android:layout_height="wrap_content" ></Button>
<Button
android:id="#+id/bSQLopenView"
android:text="#string/View"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
></Button>
</LinearLayout>
The Menu class, to fix the menu, with an OnListItemClick (there are some other activities in there, such as Overgewicht. Don't mind these, I guess..?):
package com.jacob.eindproject;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class Menu extends ListActivity implements OnItemClickListener {
String classes[] = { "BMI- Calculator", "Ondergewicht", "Gezond Gewicht", "Overgewicht", "Database", "Bekijk Database"};
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, classes));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
//Positie 0 is het eerste item (dus de BMI-Calculator.)
super.onListItemClick(l, v, position, id);
switch(position)
{
case 0:
Intent openStartingPoint = new Intent(getApplicationContext(),MainActivity.class);
startActivity(openStartingPoint);
break;
case 1:
Intent openOndergewicht = new Intent(getApplicationContext(),Ondergewicht.class);
startActivity(openOndergewicht);
break;
case 2:
Intent openGezondgewicht = new Intent(getApplicationContext(),Gezond_gewicht.class);
startActivity(openGezondgewicht);
break;
case 3:
Intent openOvergewicht = new Intent(getApplicationContext(),Overgewicht.class);
startActivity(openOvergewicht);
break;
case 4:
Intent openDatabase = new Intent(getApplicationContext(),SQLite.class);
startActivity(openDatabase);
break;
case 5:
Intent openViewdatabase = new Intent(getApplicationContext(),SQLView.class);
startActivity(openViewdatabase);
break;
}
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
}
}
My Android Manifest file: (again, I've declared some other things, don't mind these!)

EDIT:
I have a new error now, please take a look at my LogCat. I think it's because I have a wrong column set or something? Thanks in advance.

The NPE occurs at line 71 of your Database class, somewhere within the constructor or when intializing variables (that's what <init> in the stacktrace stands for.
I just read that you figured that out yourself. So the only thing that can be null here is ourHelper.
Is this really your code?
public void close() {
} {
ourHelper.close(); //This is line 71, where also an error is given, maybe there should me text between the brackets ()?
}
There's something wrong with the brackets here. I'm not sure why this compiles but I guess it does and the compiler executes the
{
ourHelper.close();
}
immediately when instantiating the class.
Change this to
public void close() {
ourHelper.close();
}
and you should be fine.

java.lang.NullPointerException Cant figure out what is causing the error

I am creating a VERY basic POS system for an assignment for class. I keep getting that dreaded nullpointerexception. I know the error is coming from line 72 in main activity but it is declared in both the main activity and in the xml.
Here is the logcat:

Any help in finding the issue with the btnTotal line in the main activity.java would be so helpful. Thanks in advance!

You don't have a btnTotal so when you click on it, the value is null.
See:
btnDairy = (Button) findViewById(R.id.btnDairy);
btnSeafood = (Button) findViewById(R.id.btnSeafood);
btnWine = (Button) findViewById(R.id.btnWine);
btnMeat = (Button) findViewById(R.id.btnMeat);
btnFruit = (Button) findViewById(R.id.btnFruit);
btnVegetable = (Button) findViewById(R.id.btnVegetable);
btnClear = (Button) findViewById(R.id.btnClear);
//add this
btnTotal = (Button) findViewById(R.id.btnTotal);
No button for btnTotal. Add that button and you'll be fine. Simple mistake. Happens all the time. Good luck.

You did not initialise your total field, so it throws NPE

RunTimeException when trying to implement GPS Locater

I am working on adding GPS location services to my app. However I get this error I just can't seem to fix. I have included all of my relevant coding. And if anybody has comments on any of my coding not related to the error I would appreciate them too.
