Android应用程序在SQLite数据库打开后崩溃

我想创建一个应用程序来获取当前的地理位置并将其存储到SQLite数据库中。之后，我希望能够检索该位置进行查看。我有代码来获取位置，但创建我的数据库后，应用程序崩溃。Android应用程序在SQLite数据库打开后崩溃

这是我的主要活动代码

public class WhereAmI extends Activity { 

SQLiteOpenHelper dbhelper; 
SQLiteDatabase database; 

double lat; 
double lng; 



@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 

LocationManager locationManager; 
String context = Context.LOCATION_SERVICE; 
locationManager = (LocationManager)getSystemService(context); 

Criteria criteria = new Criteria(); 
criteria.setAccuracy(Criteria.ACCURACY_FINE); 
criteria.setAltitudeRequired(false); 
criteria.setBearingRequired(false); 
criteria.setCostAllowed(true); 
criteria.setPowerRequirement(Criteria.POWER_LOW); 
String provider = locationManager.getBestProvider(criteria, true); 

    Location location = locationManager.getLastKnownLocation(provider); 
updateWithNewLocation(location); 

locationManager.requestLocationUpdates(provider, 2000, 10, 
             locationListener); 

//Open Database 
dbhelper = new dbHelper(this); 
database = dbhelper.getWritableDatabase(); 

//ContentValues cv = new ContentValues(); 
//cv.put(dbHelper.COULMN_LON, lng); 
//cv.put(dbHelper.COLUMN_LAT, lat); 
//database.insert(dbHelper.TABLE_LOCATION, null, cv); 
} 

private final LocationListener locationListener = new LocationListener() { 
public void onLocationChanged(Location location) { 
    updateWithNewLocation(location); 
} 

public void onProviderDisabled(String provider){ 
    updateWithNewLocation(null); 
} 

public void onProviderEnabled(String provider){ } 
public void onStatusChanged(String provider, int status, 
          Bundle extras){ } 
}; 

private void updateWithNewLocation(Location location) { 
String latLongString; 
TextView myLocationText; 
myLocationText = (TextView)findViewById(R.id.myLocationText); 
if (location != null) { 
    lat = location.getLatitude(); 
    lng = location.getLongitude(); 
    latLongString = "Lat:" + lat + "\nLong:" + lng; 
} else { 
    latLongString = "No location found"; 
} 
myLocationText.setText("Your Current Position is:\n" + 
         latLongString); 

} 

} 


Here is my Database Class 

package com.paad.whereami; 

import android.content.Context; 
import android.database.sqlite.SQLiteDatabase; 
import android.database.sqlite.SQLiteOpenHelper; 


public class dbHelper extends SQLiteOpenHelper { 


public static final String DATABASE_NAME = "geo.db"; 
public static final int DATABASE_VERSION = 1; 

public static final String TABLE_LOCATION = "tablename"; 
public static final String COLUMN_ID = "locationId"; 
public static final String COULMN_LON = "longitude"; 
public static final String COLUMN_LAT = "latitude"; 

private static final String TABLE_CREATE = "CREATE TABLE " + TABLE_LOCATION + 
     " (" + COLUMN_ID + " INTEGER RIMARY KEY AUTOINVREMENT, " 
     + COULMN_LON + " DOUBLE, " + COLUMN_LAT + " DOUBLE, " + ")"; 


//Context context; 


public dbHelper(Context context) { 
    super(context, DATABASE_NAME, null, DATABASE_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase db) { 
    db.execSQL(TABLE_LOCATION); 




} 

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

} 

}

这里是Android运行时错误我得到。在主键和自动增量

试着改变你的表的名称不是'tablename'以外的东西。另外，添加一个';'来结束你的create语句。 – 2013-02-22 06:55:57

拼写错误

而且最后DOUBLE

更改后一个额外的 “” ...

private static final String TABLE_CREATE = "CREATE TABLE " + TABLE_LOCATION + 
     " (" + COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " 
     + COULMN_LON + " DOUBLE, " + COLUMN_LAT + " DOUBLE);";

它是一个简单的错误onCreate方法，你使用了错误的常量。

更改onCreate方法来

public void onCreate(SQLiteDatabase db) { 
    db.execSQL(TABLE_CREATE); 
}
