Android App stürzt beim Versuch ab, Daten zur SQLite-Datenbank

Question

hinzuzufügen Also habe ich eine SQLite-Datenbanktabelle erstellt, die ich überprüft wurde erstellt. Allerdings stürzt die App jedes Mal ab, wenn ich versuche, Daten hinzuzufügen. Ich habe eine andere ähnliche Tabelle, die auf die gleiche Weise implementiert ist und funktioniert gut, so dass ich vermute, das Problem ist irgendwo in der Schaltfläche?

My Database Klasse:

package com.example.drivopro.drivopro; 

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 java.util.ArrayList; 
import java.util.List; 


public class DatabaseHelper extends SQLiteOpenHelper { 
    public static final String DATABASE_NAME = "Company.db"; 

    //My company table 
    public static final String TABLE_ME = "TABLE_ME"; 
    public static final String MY_ID = "ID"; 
    public static final String MY_NAME = "NAME"; 
    public static final String MY_ADDRESS = "ADDRESS"; 
    public static final String MY_ZIP = "ZIPCODE"; 
    public static final String MY_CITY = "CITY"; 
    public static final String MY_PHONE = "PHONE"; 

    public DatabaseHelper(Context context) { 
     super(context, DATABASE_NAME, null, 1); 
    } 

    @Override 
    public void onCreate(SQLiteDatabase db) {   
     db.execSQL("CREATE TABLE " + TABLE_ME + "(ID INTEGER PRIMARY KEY AUTOINCREMENT,NAME TEXT,ADDRESS TEXT,ZIPCODE TEXT,CITY TEXT,PHONE TEXT)"); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     db.execSQL("DROP TABLE IF EXISTS " + TABLE_ME); 
     onCreate(db); 
    } 

    public boolean insertMyCompany(String name, String address, String zipcode, String city, String phone) { 
     SQLiteDatabase db = this.getWritableDatabase(); 
     ContentValues contentValues = new ContentValues(); 
     contentValues.put(MY_NAME, name); 
     contentValues.put(MY_ADDRESS, address); 
     contentValues.put(MY_ZIP, zipcode); 
     contentValues.put(MY_CITY, city); 
     contentValues.put(MY_PHONE, phone); 
     long result = db.insert(TABLE_ME, null, contentValues); 
     if (result == -1) 
      return false; 
     else 
      return true; 
    }   
} 

Aktivität Ich arbeite mit:

package com.example.drivopro.drivopro; 

import android.content.Intent; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.Toast; 

public class ModifyCompanyInfo extends AppCompatActivity { 

    DatabaseHelper myDb; 
    Button btnsave; 
    EditText changeName, changeAddress, changeZip, changeCity, changePhone; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_modify_company_info); 

     btnsave = (Button)findViewById(R.id.saveComp); 
     changeName = (EditText)findViewById(R.id.myName); 
     changeAddress = (EditText)findViewById(R.id.myAddress); 
     changeZip = (EditText)findViewById(R.id.myZip); 
     changeCity = (EditText)findViewById(R.id.myCity); 
     changePhone = (EditText)findViewById(R.id.myPhone); 

     addData(); 
    } 

    public void addData(){ 
     btnsave.setOnClickListener(
       new View.OnClickListener() { 
        @Override 
        public void onClick(View v) { 
         boolean isInserted = myDb.insertMyCompany(changeName.getText().toString(), 
           changeAddress.getText().toString(), 
           changeZip.getText().toString(), 
           changeCity.getText().toString(), 
           changePhone.getText().toString()); 
         if(isInserted) 
          Toast.makeText(ModifyCompanyInfo.this, "Tietoja muutettu", Toast.LENGTH_LONG).show(); 
         else 
          Toast.makeText(ModifyCompanyInfo.this, "Mitään ei tapahtunut", Toast.LENGTH_LONG).show(); 
        } 
       } 
     ); 
    } 
}

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_modify_company_info); 

    myDb = new DatabaseHelper(this); //Intialize the database object 
}
