Bonjour,

Je crois que je tourne en rond, merci de jeter un oeil avisé ...

Je voudrais exploiter une base SQLITE existante que j'ai rapatrié dans data/data/monPackage/databases/ en m'inspirant de ça : http://www.reigndesign.com/blog/usin...-applications/

Voici la sous-classe de SQLiteOpenHelper

Code :

import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
 
 
public class WpBdd extends SQLiteOpenHelper
{
	private static String DB_PATH = "/data/data/org.BddWpApp.riAndroid/databases/";
 
    private static String DB_NAME = "WP02-BddSqliteOK.db";
 
    private static SQLiteDatabase myDataBase; 
 
    private final Context myContext;
 
    // constructeur
	public WpBdd(Context context ) //, String name, CursorFactory factory,int version)
	{
    	super(context, DB_NAME, null, 1);
        this.myContext = context;
    }
 
	@Override
	public void onCreate(SQLiteDatabase arg0) {
		// TODO Auto-generated method stub
	}
 
	@Override
	public void onUpgrade(SQLiteDatabase arg0, int arg1, int arg2) {
		// TODO Auto-generated method stub
	}
 
	public static void openDB() 
	{
		//Open the database
    	String myPath = DB_PATH + DB_NAME;
    	myDataBase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);
 
	}
}

Puis l'activité :

    	else

    		wpBdd.close() ;
    		flag = true ;
    		showCode.setText("Close");
    	}	
 
	}
}

Pour l'essai le but est de faire une requette (qui fonctionne par aileurs) permettant de retrouver un enregistrement. Le code ne révoit pas l'exploitation, avant, il vaudrait mieux trouver pourquoi le RawQuery plante...
Bien sûr ça plante (sinon je ne vous le soumettrais pas !) et voilà ce que dit le LogCat :
